WRT600N - Network Sharing / Storage Issues

I recently bought a WRT600N v1.0 from Dell.com and configured the router (I'm a CCNP, so I've been using routers, etc.. for years). I had a WRT54GS v1.0 before this and that worked great for years.
The WiFi (both 5GHz and 2.4GHz) has been rock solid on the WRT600N, but my issue is with the network sharing/storage (NAS) part of the router.
I plugged in a Seagate USB 2.0 750GB HDD (already formatted to NTFS using Windows Vista). I was able to create folders and share them out. However, I cannot map a drive to about half of the folders. All folders are set up the exact same way, and even those I can map a drive to.. the network performance copying files to those shares is horrible (even over Gigabit Ethernet). I'm talking like 1MB/s, when I was getting 20MB/s using my old solution.
When I formatted the disk using the WRT600N, it only allowed me to format it to FAT, not even FAT32 or NTFS. Then it would still only work half the time.
Any ideas?
This seems like a FW issue, like many brand new Linksys products. I've already contacted Linksys support and they don't have a beta FW available to resolve this either.

Have you fixed your issues with the storage feature of this router...? I recently bought the WRT600N router and the SAME exact Seagate HD for the storage link feature. I have spent over 15 hours numerous phone calls to Linksys Techs and My Computer Works Techs and NOTHING doing, it still does not work right.
I have set up my drive and I to had to FORMAT using the FAT system of the router per one of the Linksys Supervisor Techs. I did this and set up everything related to my drive and MAPPED all my drives... I have access to all the drives at first and can move files around and delete from the network.
I wait for a few minutes and open a NEW program and try to SAVE to the network drive location and get "You Need Permission to Preform This Action. Try Again or Cancel" are the only options I get and NO REQUEST for a paswsword is given. I am administrator and cannot now access my drive / network...
The TECH's for MCW are puzzled as well as they initially set the drive and Share folders up. They cannot figure out why there continues to be a problem accessing the folders on the drive.
I spent 2 1/2 hours tonight on the phone with LinkSys and got really no healp only try this and try that. While experiencing the problems with the tech on the phone, I preformed a REFRESH on the Storage / Disk page and ALL Share Files I created Disappeared. I looked physically at my router and discovered the USB was now out...Why? The TECH thought is was a loose connection. NEW Router and NEW HD. Both are in a secure location and no one around to touch them. I could not get the router to discover the HD plugged into the USB location so I finally unplugged it and plugged it back in.
All setting remained and the router came back up without what seemed to be any hitches. At this point, I played with the configuration settings while on what seemed like eternal hold and FINALLY got access to the NETWORK drives and was able to save to all the partitions that were created.
The Tech decided that all was OK and we disconnected and guess what... I again tried to SAVE to the a partition and "You Need Permission to Preform This Action. Try Again or Cancel" came up again.
I am TRULY frustrated with this NEW SETUP and don't know what to do now. Can anyone help me fix this thing to make it work right?????
One thing you will learn about LinkSys, is that they have the best prodcuts out there..but if you buy a first generation product (such as the WRT600N), it will have issues that will take firmware updates to resolve the problems. The best thing is to report the issues and wait a few months until several firmware updates come out to resolve the problems.
I recently installed the latest FW update and my WRT600N has been acting "better", but still needs a few more FW updates to fix the other stability issues. I'm fully prepared to wait it out, but it is unfortunate that we have to wait anything out...as LinkSys Q/A should have caught these bugs prior to product release and had them fixed then.
I've tried products from NetGear, Belkin, etc.. and all of them are horrible. At least LinkSys products work once the FW updates come out. I just hope you never need to contact LinkSys support as they are horrible.
Here's my configuration:
- WRT600N v1.0
- Latest FW
- Seagate 750GB USB 2.0 External HDD formatted to NTFS using Windows Vista
- Shared folders created using WRT600N
- Media Server Enabled (still does not work with my Playstation 3)
- File write performance, still horrible..even over Gigabit Ethernet (around 200KB/s, should be around 4-5MB/s at least)
- File share mapping, still intermittent.. usually works.. but I noticed it seems to be case senstitive in mapping the drive names (odd)
- Should have an option to format the HDD as FAT, FAT32 or NTFS (only FAT is used currently)

Uninstalling VMM 2012 SP1 can cause any Network or Shared Storage Issues?

Hello There,
I'm studying for the 70-409 Exam and also planning to reinstall the VMM 2012 on my company, since it was created a long time ago and somehow the old administrator created the environment in a way that only he could understand.
After looking online and don't find any answers, I decided to create this thread to see if anyone can help me. My questions are:
1 - If I Uninstall the VMM, my Hosts will loose any network configuration? I already checked and I am not using any Logical Switches in the current configuration, and only have some Logical Networks created. Removing the VMM can cause any network issues
on the physical hosts or in the VMs under it?
2 - Is there a guid somewhere about the Uninstall process? It could be in a book, there is no problem in buying it, but i really cannot find it anywhere.
Thanks!

Hello Ed,
So, it will cause some disruption, but the VM's and the Hyper-V Hosts will be disconnected from the Network or it will be a "temporary" disruption?
I Will try to explain better my concern: The VMM, as it is on my company, is useless. I really need to rebuild the entire Farm from the Scrath, document the project and start to use the VMM software. We are starting to use a lot of Hyper-V Vms and it's very
hard to keep using the Hyper-V Manager.
I dont have Logical Switches in place, neither IP Address Pool published. I got some Logical Networks and VM Networks in place, but my Logical Networks are empty, with no IP Address and Sites/VLAN associated.
I Also don't have any Storages Published on the Fabric. If I remove my VMM server, i will change something on the Vswitches of the Physical Servers? Which will be the best plan to reinstall my Hyper-V Farm?
Thank you!

File sharing in Network Attached Storage

This isn't strictly a Mac question, but I always get good advice, so here goes: We are a design shop using Macs for CAD and similar work. We want to get a NAS for centralized file sharing. But how does the NAS handle two people using a file at the same time? If user A opens and modifies a file, but doesn't save or close it, what does user B see when he opens the same file on the NAS? Is there a way to restrict access to one user at a time? This seems a prudent strategy. Some of the NAS models we're looking at offer an even more confusing Dropbox-like synced folder system that resides on each machine. Same question: if I open a file on my machine that is NAS-synced, what does my neighbor see? Thanks to anyone for your help!

Hi,
You need not to use MSCS cluster solution for TREX distributed installation. You can have all data on central storage that can be NFS mounted or on SAN that can be access by both master and slave servers. Check installation guide. Please find an extract from the guide:
Centralized Data Storage
With centralized data storage, the data is stored so that all TREX hosts can access it.
Centralized data storage can be realized with different hardware solutions: The data can be located on a server that is optimized for file sharing, in a storage area network (SAN), or on a network attached storage server (NAS server). It is important that the connection between the TREX hosts and the data is sufficiently fast. In the following documentation, a central storage location is referred to as a file server regardless of the underlying hardware.
Centralized data storage is necessary if you want indexing to be highly available. You can only move from a master index or queue server to a backup index or queue server if you are using centralized data storage. You can use standard solutions such as the RAID system to make data highly available.
Centralized data storage also has the following advantages if you are only using master and slave hosts:
● Index replication generates less of a network load because the replicated files do not have to be copied onto every slave host.
● Index replication is quicker.
● Less disk space is required for the replicated indexes because all slave hosts share an index copy.
Thanks

Shared variable engine network published source issue

Hello,
I am attempting to use the shared variable engine to share some simple stings over a network between a Windows 7 computer and a Windows XP computer.
I got through the shared variable example just fine and can share variables between VIs on a single computer. When I open the shared variable engine, it shows the client and server variables that are shared on the local computer. I then create a new process, and attempt to define a new variable, and the Shared Variable Property screen comes up. I attempt to "Bind to Source" and click browse, and see the computer name I am attempting to connect to. However, when I click it, it stalls and I cannot expand the computer to find the variable I am trying to bind to. What am I missing?
Thanks, Arron

Arron,
This document may be useful in helping to setup your network shared variables. Take a look at this and see if you have followed all the outlined steps in setting up a network shared variable.

Access iphoto 08 file on shared storage device from multiple machines

I recently installed ilife 08 on both an imac and macbook. Previously (iphoto 06), both devices accessed the iphoto library on a shared storage device without any problems. After the upgrade, my imac is able to view thelibrary but my macbook (the second machine to be upgraded) no longer has access. 'Sharing' is too slow over the wireless network and doesn't represent a reasonable option.
Is anyone else experiencing this issue? Any suggestions.

Actually, neither repairing permissions or changing them with Get Info worked for me. What did work for me was deleting the empty iPhoto Library in the user folder who couldn't access the shared library, and put an alias of the shared library in that user's Pictures folder. Everything then worked as it did prior to upgrading. Thanks.

Qmaster error: shared storage client timed out while subscribing to...

Here's my Qmaster setup:
computer 1: CONTROLLER, no nodes
- 8TB RAID hooked up via Fiber
- connected to the GigE network switch via a 6-port bond
- cluster storage set to a path on the RAID
computers 2, 3, 4, 5: RENDER NODES
- each computer has a 2-port bonded connection with the GigE switch
computer 6: Client, with FCS2 installed.
- connected with a single GigE link
I have set up this cluster primarily for command-line renders, and it works great. I submit command-line renders from the client computer, which get distributed and executed on each node. The command line renders specify a source file on the RAID, and a destination path on the RAID. Everything works great.
I run into trouble when trying to use Compressor with this same setup. The files are on the RAID, and all my computers have an NFS automount that puts it in the /Volumes folder on each computer.
I set up my Compressor job and submit it to the cluster. It submits sucessfully, and distributes the work. After a few seconds, each node gives me a timeout error:
"Shared storage client timed out while subscribing to [computer1.local/path to cluster storage]"
Is this a bandwidth issue? Command line renders work fine, I can render 16 simultaneous Quicktimes to the RAID over NFS. I don't see much network activity on any of the computers when it's trying to start the Compressor render, it's as if it's not even trying to connect.
If I submit the SAME compressor job to a cluster with nodes ONLY on the controller computer, it renders fine. Clearly the networked nodes are having trouble connecting to the share for some reason.
Does anybody have any ideas? I have tried almost everything to get this to work. Hooking up each node locally to the RAID is NOT an option unfortunately.

WELL I DO NOW!
Thanks. it's taken 6th months and several paid 'professionals' and then you come in here...swinging your minimalist genius. one line. one single line. and its done.
if you are in london, lets lift a beer or five together.
thank you sir. thankyou!

Installing RAC on External Network Attached Storage

Is it possible to use External Network Attached Storage device to install Oracle RAC?
It is much cheapter than to buy SAN or other devices.. All I am thinking it buying a External NAS enclosure and put a couple of hard disks in it and use it as NAS to store RAC database..
any suggestions?
Thanks
Data Sheet

Since you only want to learn ... Google for RAC SCSI or RAC Firewire
Based on my experience, my suggestions and observations around RAC are simple
1) Go straight to 10g, do not bother with 9i;
2) If you are a competent Oracle10g DBA, RAC knowledge is a mininal upgrade in effort;
3) 99.9% of the 'RAC problem' is from the hardware configuration.
I find that the RAC configuration issues are different for each operating system and storage subsystem combination I seen, and they have almost nothing to do with RAC. They are mainly about system, network and disk administration and making them able to handle a shared disk configuration. Once the stable shared disk configuration is achieved RAC is almost self-installing.
So, going cheap just to learn RAC is not going to provide much headway in the long run.
However, being able to say you've seen it is possibly worth while, and that can be accomplished very inexpensively using SCSI or Firewire disks. Do the web search - there are a lot of cookbooks.
Note though that Jonathan Lewis recently said, and I paraphrase: "A 2-, or even 3- node RAC is not really interesting. 2-node is a boundary condition, and 3 node falls back to boundary condition quickly. Detailed investgation doesn't happen until you have 4 or more nodes." And that requires a real configuration. Which is going to cost.
And no - I do not know anything about Z-SAN.

WRT610N Shared Storage

I recently purchased a WRT610N and have been having some problems setting up the USB shared storage feature. I have a 1.5 Terabyte Seagate drive that I have created two partiions on (I had read elsewhere in the forums that the WRT610N only handled partitions/dirves up to 1 TB). Both partitions are NTFS with the first one being 976,561 GB and the second one being 420,700 GB. Both drives show up in the "Disk" section of the admin console and I can create/define a share for the larger of the two partitions without any problems.
The first of my problems comes when I try to create/define a share for the smaller partition. I can create a share but the admin console does not save the access privleges that I assign to it. Despite setting them up in the admin console they don't show up when I go back and look (in both the detail and summary views) the Access rights show as blank. I do not have this issue with the larger partition where I can add and later view groups in the Access section.
The second problem comes when I try to attach to the larger share from a network client. I can look at the shares if I use ..........Start - Run - and Type \\192.168.1.1. If I enter in my admin User ID and password, I can see the new share on the WRT610N. When I try to double click on it, I am then pompted again for a Username & Password, When I try to re-enter the admin user ID and password, the logon comes right back to me with "WRT610n\admin" populated in the User ID field. From there it won't accept the admin password. There are no error messages.
Help with either problem would be appreciated.

When you select your Storage partition and open it, and if it ask you for the Username and Password, thats the username and password is of your storage drive, Might be you must have set some password for your storage drivers.
Login to your Routers GUI. and click on the Storage Tab and Below you will find the Sub tab "Administration" click on it, if you wish you can Modify the "admin" rights, Like change the password or else you can Create your Own User and password. So whenever you login to your Storage Partition, and it ask for the username and password then you can input that username and password and click OK. This way you will be able to access your Storage Driver.

Acessing shared storage

For some reason I just cannot access the shared storage device on my home network. The device appears as a media device, but not as a computer as it normally does. I have tried every kind of troubleshooting, but nothing seems to work.

Hi,
If the issue did not occur before, you may try to use the system restore, return to the point which did not appear the problem.
Please try the following:
1. Check the permission settings of the network storage device: Add Everyone to Sharing tab and Security tab
2. Adjust "File sharing connections” encryption setting:
a. Go to “Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings”.
b. Adjust the File sharing connections setting and check if the computer can access the network storage device.
3. Please temporarily disable Windows Firewall and security software.
4. Try to manually use UNC (\\server\share) and IP (\\ip.add.res.s\share) to access the device for a test.
Please also use Device Manager to verify that your network adapter is working correctly and reinstall the drivers.
If the shared folder still can’t be accessed, please re-create the connection and check the result again.
Hope it helps.

Airport Extreme and NAS (Network Attached Storage)

I am using a brand new AirPort Extreme (ver. 7.4.2) connected to a Motorola cable modem, with two different MacBooks running Snow Leopard, two AirPort Express units for distributing music wirelessly around the house, and an HP multifunction printer connected to the Extreme via USB, all of which works fine.
But I recently purchased a 1TB Iomega Home Media network attached storage device (NAS), which is connected to the Extreme via ethernet cable, and I can't get the Extreme or either MacBook to recognize the NAS drive. The NAS doesn't "mount" on the desktop like a USB external drive would. It doesn't appear under "Shared" in Finder. It doesn't appear in AirPort Utility under "AirPort disks". Oddly enough the only place where the NAS does appear is in iTunes under "Shared"!
I know that the NAS device is functioning properly because my IT guy tested it at the office, connected to his PC, and it worked fine. The NAS came with Iomega "Home Storage Manager" software, which I installed but it's pretty useless because it also can't "find" the NAS and only offers to re-scan for it.
Much to my surprise there is very little information about troubleshooting NAS storage with the Extreme, either on the Support forums or in the "Apple Airport Networks" document published by Apple in early 2009.
I would greatly appreciate any guidance!
Thanks in advance,
MG

Thanks to both of you for your input. The Iomega NAS (Home Media Network Hard Drive is the model) comes ready out of the box for use with either PC or Mac.
Actually I resolved the problem by going to Iomega's tech support page. I needed to download an updated version of the Home Storage Manager software as well as 2 firmware updates to the NAS drive itself; so that it would be compatible with Snow Leopard. That was the issue. Now it appears to be working just fine.
Thanks again & happy holidays.

I want a new and more powerful (non-Apple) wireless router but I still want to use my existing Time Capsule to continue with my Time Machine backups and I still need the Time Capsule's Network Attached Storage (NAS) features and capabilities

THE SHORTER STORY
My goal is to successfully use my existing Time Capsule (TC) with a new and more powerful wireless router. I need a new and more powerful wireless router in order to reach a distant Denon a/v receiver that is physically located in a master bedroom some 50 feet away from my modem. I need to provide this Denon a/v receiver with an Internet connection so that it can obtain its firmware updates and I need to connect this Denon a/v receiver to my network in order to use its AirPlay feature. I believe l still need the TC's Network Attached Storage (NAS) features because I am not sure if the new wireless router will provide me with the NAS like features / capabilities I need to share files between my two Apple laptops with OS X 10.8.2. And I know that I absolutely need my TC's seamless integration with Apple's Time Machine (TM) application in order to continue to make effortless backups of my two Apple laptops. To my knowledge nothing works with TM like Apple's TC. I also need the hard disk storage space built into the TC.
I cannot use a long wired Ethernet cable connection in this apartment and I cannot use power-line adapters. I have read that wireless range extenders and repeaters are difficult to successfully set-up and that they will reduce data speeds, especially so when incorrectly set-up. I cannot relocate my modem and/or primary base station wireless router.
In short, I want to use my TC with my new and more powerful wireless router. I need to stop using the TC to connect to the modem. However, I still need the TC for seamless TM backups. I also need to use the TC's built in hard drive for storage. And I may still need the TC's NAS capabilities to share files wirelessly between laptops because I am assuming the new wireless router will not provide NAS capabilities for OS X 10.8.2 (products like this/non-Apple products rarely seem to work with OS X 10.8.2/Macs to provide NAS features and capabilities). Finally, I want to continue to use my Apple laptop and AirPlay to wirelessly access and play my iTunes music collection stored on the TC's hard drive. I also want to continue to use my Apple laptop, AirPlay and Apple TV to wirelessly watch movies and TV shows stored on the additional external hard drive connected to the TC via USB. Can someone please advise on how to set-up my new Asus wireless router with my existing TC in such a way to accomplish all of this?
What is the best configuration or set-up to accomplish my above goals?
Thank you in advance for your assistance!!!
THE FULL STORY
I live in an apartment building where my existing Time Capsule (TC) is located in my living room and serves many purposes. Specially, my TC is at least all of the following:
(1) Wi-Fi router connected to Comcast Internet service via Motorola SB6121 cable modem - currently the TC is the Wi-Fi base station that connects to the modem and has the gateway address to the Internet. The TC now provides the DHCP service for the Wi-Fi network.
(2) Wireless router providing Internet and Wi-Fi network access to several Wi-Fi clients - two Apple laptop computers, an iPod touch, an iPad and an iPhone all connect wirelessly to the Internet via the TC.
(3) Wired Ethernet router providing Internet and Wi-Fi network access to three different devices - a Panasonic TV, LG Blu-Ray player and an Apple TV each use one of the three LAN ports on the back of the TC to gain access to the Internet.
(4) Primary base station in my attempt to extend my wireless network to a distant (located far away) Denon a/v receiver requiring a wired Ethernet connection - In addition to the TC, which is my primary base station, I am also using a second extended Wi-Fi base station (a Netgear branded product) to wirelessly extend my WiFi network to a Denon receiver located in the master bedroom and requiring a wired Ethernet connection. I cannot use a wired Ethernet connection to continuously travel from the living room to the master bedroom. The distance is too great as I cannot effectively hide the Ethernet cable in this apartment.
(5) Time Machine (TM) backup facilitator - I use my TC to wirelessly back-up two Apple laptops using Apple's Time Machine (TM) application. However, I ran out of storage space on my TC and therefore added external storage to it. Specifically, I added an external hard drive to my TC via the USB port on the back of the TC. I now use this added external hard drive connected to the TC via USB as the destination storage drive for my TM back-ups. I have partitioned the added external hard drive, and each of the several partitions all have enough storage space (e.g., each of the two partitions used by TM are sized at three times the hard drive space of each laptop, etc.). Everything works flawlessly.
(6) Network Attached Storage (NAS) - In addition to using the TC's Network Attached Storage (NAS) capabilities to wirelessly back-up two Apple laptops via TM, I also store other additional files on both (A) the hard drive built into the TC and (B) the additional external hard drive connected to the TC via USB (there are additional separate partitions on this drive for these other additional and non-TM backup files).
I use the TC's NAS feature with my Apple laptop and AirPlay to wirelessly access and play my iTunes music collection stored on the TC's hard drive. I also use my Apple laptop, AirPlay and Apple TV to wirelessly watch movies and TV shows stored on the additional external hard drive connected to the TC via USB. Again, everything works wirelessly and flawlessly. (Note: the Apple TV is connected to the network via Ethernet and a LAN port on the back of the TC).
The issue I am having is when I try to listen to music via Apple's AirPlay in the master bedroom. This master bedroom is located at a distance of two rooms away from the TC's current location in the living room, which is a distance of about 50 feet. This apartment has a long rectangular floor plan where each room is connected to the next in a straight line. In order to use AirPlay in the master bedroom I am using a second extended Wi-Fi base station (a Netgear branded product) to wirelessly extend my WiFi network to a Denon receiver located in the master bedroom and requiring a wired Ethernet connection. This additional base station connects wirelessly to the WiFi network provided by my TC and then gives my Denon receiver the wired Ethernet connection it needs to use AirPlay. I have tried moving my iTunes music directly onto my laptop's hard drive, and then I used AirPlay on this same laptop to connect to the Denon receiver. I always get a successful connection and the song plays, but the problem is that the connection inevitably drops.
I live in an apartment building and all of the many wireless routers in this building create a great deal of WiFi interference on both the 2.4 GHz and 5GHz bands. I have tried connecting the Netgear product to each the 2.4 and 5 GHz bands, but neither band can successfully maintain a wireless connection between the TC and the Netgear product. I also attempted to maintain a wireless connection to an iPod touch using the 2.4 GHz band and AirPlay on this iPod touch to play music on the Denon receiver. Again, I was able to establish a connection and successfully play music, but after a few minutes the connection dropped and the music stopped playing. I therefore have concluded that I have a poor wireless connection in the master bedroom. I can establish a connection, but it is intermittent with frequent drops. I have verified this with both laptops by working in the master bedroom for an entire day on both laptops. The Internet connection in this master bedroom proved to drop out frequently - about once an hour with the laptops. The wireless connection and the frequency of its dropout are far worse with the iPod touch and an iPhone.
I cannot relocate the TC. Also, this is an apartment and I therefore cannot extend the range of my network with Ethernet cable (I cannot drill through walls/ceilings, etc.). It is an old building with antiquated wiring and power-line adapters are not likely to function properly, nor can I spare the direct power outlet required with a power-line adapter. I simply need every outlet I can get and cannot afford to block any direct outlet.
My solution is to use a more powerful wireless router. I found the ASUS RT-AC66U Dual-Band Wireless-AC1750 Gigabit Router which will likely provide a better connection to my wireless Internet in the master bedroom than the TC. The 802.11ac band of this Asus wireless router is totally useless to me, but based on what I have read I believe this router will provide a stronger connection at greater distances then my TC. And I will be ready for 802.11ac when it becomes more widely available.
However, I still need to maintain the TC's ability to work seamlessly with TM to backup my two laptops. Also, I doubt the new Asus router will provide OS X 10.8.2 with NAS like features and capabilities. Therefore, I still would like to use the TC's NAS capabilities to share files on my network wirelessly assuming the Asus wireless router fails to provide this feature. I need a new and more powerful wireless router, but I need to maintain the TC's NAS features and seamless integration with TM. Finally, I want to continue to use my Apple laptop and AirPlay to wirelessly access and play my iTunes music collection stored on the TC's hard drive. I also want to continue to use my Apple laptop, AirPlay and Apple TV to wirelessly watch movies and TV shows stored on the additional external hard drive connected to the TC via USB. Can someone advise on how to set-up my existing TC with this new Asus wireless router in such a way to accomplish all of this?

In regards to a Plan B, I hear ya brother. I am already on what feels like Plan Z. Getting WiFi to a far off room in an apartment building crowded with WiFi routers is a major pain.
I am basing my thoughts on the potential of a new and more powerful router reaching the far off master bedroom based on positive reviews on cnet.com, pcmag.com and pcworld.com. All 3 of these web sites have reviewed the Asus RT-AC66U 802.11AC wireless router as well as its virtual twin cousin 802.11n router. What impressed me is that all 3 sites rated this router #1 overall in terms of both range and speed (in both the 802.11n and 802.11AC flavors). They tested the router in real world scenarios where the router needed to compete with a lot of other wireless routers. One of the sites even buried this Asus router in a media room with thick walls and inside a media cabinet. This Asus router should be able to serve my 2.4 GHz band wireless clients (iPod Touch and iPhone 4) with a 2.4GHz Wireless-N band offering some 50 feet of dependable range and a 60 Mbps throughput at that range. I am hoping that works, but it's borderline for my master bedroom. My 5 GHz wireless clients (laptops) will enjoy a 5GHz Wireless-N band offering 150 feet of range and a 200 Mbps throughput at that range. I have no idea what most of that stuff means, but I did also read that Asus could reach 300 feet and I got really excited. My mileage may vary of course and I'm sure I'm making some mistakes in my interpretation of their data. However, my Winter 2009 Time Capsule was rated by cnet.com to deliver real world performance of less than that, and 802.11AC may or may not be useful to me someday. But when this Asus arrives and provides anything other than an excellent and consistent wireless signal without drops in the master bedroom it's going right back!
Your solution sounds great, but I have some questions. I'm using OS X 10.8.2 and Airport Utility (version 6.1 610.31) and on its third tab labeled "Wireless" the top option enables you to set "Network Mode" to either:
Create a wireless network
Extend a wireless network
Off
Given your advice to "Turn off the wireless on the TC," should I set Network Mode to Off? Sorry, I'm clueless in regards to how to turn off the wireless on the TC any other way. Can you provide specific steps on how to turn off the wireless on the TC? If what I wrote is correct then what should the rest of this Wireless tab look like, or perhaps it is irrelevant when wireless is off?
Next, what do you mean by "Configure the TC in Bridge Mode?" Under Airports Utility's fourth tab labeled "Network" the top option "Router Mode" allows for either:
DHCP and Nat
DHCP Only
Off (Bridge Mode)
Is your advice to Configure the TC in Bridge Mode as simple as setting Router Mode to Off (Bridge Mode)? If yes, then what should the rest of this "Network" tab look like? Anything else involved in configuring the TC in Bridge Mode or is it really as simple as setting the Router Mode to "Off (Bridge Mode)"?
How about the other tabs in Airport Utility, can they all stay as is assuming I use the same network name and password for the new Asus wireless router? Or do I need to make any other changes to the TC via Airport Utility?
Finally, in regards to your Plan B suggestion. I agree. But do you have a Plan B for me? I would greatly appreciate any alternative you could provide. Specifically, if you needed a TC's Internet connection to reach a far off corner of your home how would you do it? In the master bedroom I need both a wired Ethernet connection for the Denon a/v receiver and wireless Internet connection for the iPhone and iPod Touch.
Power-Line Adapters - High Cost, Blocks at Least One Wall Outlet and Does Not Solve the Wireless Need
I actually like exactly one power-line adapter, which is the D-Link DHP-540 PowerLine AV 500 4-Port Gigabit Switch. This D-Link power-line adapter plugs into your wall outlet with a normal sized plug (regular standard power cord much like any other electronic device) instead of all of the other recommended power-line adapters that not only use at least one wall outlet but also often block the second outlet. You cannot use a power strip with a power-line adapter which is very impractical for me. And everything about my home is strange and upside down. The wiring here is a disaster and I don't have faith in its ability to carry Internet access from the living room to the master bedroom. And this D-Link power-line adapter costs $90 each and I need at least two to make the connection to the Denon A/V receiver. So, $180 on this solution and I still don't have a dependable drop free wireless connection in the master bedroom. The Denon might get its Ethernet Internet connection from the power-line adapter, but if I want to use an iPhone 4 or iPod Touch to stream AirPlay music to the Denon wirelessly (Pandora/iTunes, etc.) from the master bedroom the wireless connection will not be stable in there and I've already spent $190 on just the two power-line adapters needed.
Extenders / Repeaters / Wirelessly Extending the Wireless Network
I have also read great things about the Amped Wireless High Power Wireless-N 600mW Gigabit Dual Band Range Extender (Repeater) SR20000G and the My Net Wi-Fi Range Extender. The former is very powerful and the latter is easier to install. Both cost about $150 ish so similar to a new Asus router. However, everything I read about Range Extenders points to them not being very effective for a far off corner of your house wherein it's apparently hard to place the range extender in the sweet spot where it both gets a strong enough signal to actually effectively extend the wireless signal and otherwise does not reduce network throughput speeds to unacceptable speeds.
Creating a Roaming Network By Hard Wiring with Ethernet Cable - Wife Would Say, "**** No!"
Even Apple seems to warn against wirelessly extending your network (see: http://support.apple.com/kb/HT4145#) and otherwise strongly recommends a roaming network where Ethernet cable is used to connect two wireless base stations. However, I am in an apartment where stringing together two wireless base stations with Ethernet cable would have an extremely low wife acceptance factor (WAF). I cannot (both contractually and from a skill prospective) hide Ethernet wire in the walls or ceiling. And having visible Ethernet cable running from room-to-room would be unacceptable, especially to the wife.
So what is left? Do you have a Plan B for me? Thanks in advance for your help!

Oracle 10g RAC using ASM - Storage Issue

I’ve an issue related to Oracle 10g RAC.
I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
I’ve EMC CX300 SAN storage with following partitions
/orasoft     10 Gb          OCFS2 File system
/oracrs          2 Gb          OCFS2 File system
/orabackup      100 Gb          OCFS2 File system
The datafiles are on ASM which is not directly visible in OS.
I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
I’ve faced an issue recently related to EMC storage.
The /orasoft partition displays 1.4 Gb space available using df command.
With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
Is this setup correct ??
Can anyone help me with this storage issue ??

Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
Here is what you can do:
- Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
- Create a ASM disk group which would mirror Disk_1 to Disk_2.
Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.

Hi,
If you create a new diskgroup you may be to add the same diskgroup to parameter file or spfile and which will be needing down time.
sugestion: Instead of creating new diskgroup you should to add disk to existing group.if you add asm disk to existing group your all problem will be solved and Oracle itself will be managing all.And than i am sure no need to add entry in the parameter or spfile like +db_create_file_dest=.....

Distributed application: Networked Shared Variables, Named Services (Raw TCP/IP) or Other?

Happy New Year NI forums!
I am working on a project involving mobile interacting robots. In the future it is likely the application's components may need to run on different PCs (Targets). Note: at this point in time all the components are seperate but all running on the localhost machine. Thinking towards the future I want to pick the 'best' architecture to allow all these components (VIs performing various functions) in multiple locations. For example, several VIs on the Robots, VIs on serveral PCs.
I am currently aware of using Server/Client TCP/IP using named services. My mock up works well, but is it time efficient (my time coding) I wonder.. ?
Whereas I am aware of networked shared variables which handle connections and all the parsing for the underlying tcp/ip communication. But will this be difficult the manage? I am unsure if I can associate shared variables with a VI similar to named services. I suppose I could pro grammatically create the variable upon initialization of the server component - and the client could just search the list of avaiaible variables to connect too. Downside this would require DSC module.
As you can see, I am rather unsure. Any advice would be great!
Kind Regards,
James

Hi Jason,
Thanks for your reply. I hope your enjoying NI UK as much as I did.. fun times!
I have seen the link you posted a few times before. But today, I took a better look at it.
My issue is I need several multi-client severs, i.e. many servers which allow multiple clients to connect to them.
Now the STM does have an example of this - STM mutli-client Example - Server.vi (used with the STM mutli-client.vi)
However, when a make copies of these code (to have my second server) - it refuses to run. As in , it just stops itself.
I DID change the port number, on the lister aspect of the server code. But I Am unsure what else I would need to change to get this setup to work?
One thought I had was, the FIFOs all having the same name - this probably isn't a good idea between servers.
Any suggestions would be grateful!
*please could you provide me email support

Network shared variables lose binding

Hello,
I am developing an application in LabVIEW that uses network shared variables to transmit data between two PC's on the same subnet. The shared variables work fine when running the VI's in development mode, however, when i build the vi's into an executable I find that they no longer work. Here is what I have found so far:
I deploy the shared variable library on the publisher machine (also happens to be the development machine) through an invoke node in the executable. NI distributed system manager confirms that this does deploy and indeed updates as it should.
For the executable on the subscriber PC I created a second shared variable library (same project) with the same shared variables and bound them to the respective shared variables from the first library by selecting enable aliasing, then bind to PSP URL and browsing to the shared variable I wish to bind it to (e.g. \\hallnet-ellm2\shared variable library\serial Number). The machines listed under browse were listed by name so when I tried this initially and it did not work I manually changed the name of my machine in the URL box to the IP address of the publisher hoping that would fix it in case the subscriber could not resolve the publishers machine alias. So now my bind URL read \\192.168.0.1\shared variable library\serial Number.
As part of the executable on the subscriber I deploy this second shared variable library. NI distributed system manager confirms that this deploys but under quality for an individual variable it has a list of issues (see attached) and the bound variable is not updating. At this point the publisher shared variables are still functioning fine. By clicking on 'edit variable' I can see that the variable on the subscriber is still bound but the PSP URL is now \\localhost\shared variable library\serial number. Changing the PSP URL on the subscriber to \\192.168.0.1\shared variable library\serial number enables the variable to update as expected.However by this time my executable has already picked up the error and does not function.
I think that the issue lies with the bind URL used on the subscriber as for some reason it does not keep the binding configured in the project and instead changes to 'localhost'. Why is this? Should it not stay bound to the address specified in the project?
I have tried changing the IP addresses in the aliases file so that
[My Computer]
My Computer=localhost
becomes
[My Computer]
My Computer=ip of local machine
This did not help.
The shared variable libraries are included in the build spec to go into the support files directory and they are successfully deployed from there on both publisher and subscriber.
I am using LabVIEW 8.6 on Windows XP
Thanks for any help you may be able to offer,
Lee

Hi Lee,
I hope you are well. Thank you for your post. Your application sounds very interesting.
Looking at your issue I was wondering, have you tried lowering your firewalls, as this may be causing the problem.
Also, another option would be to setup a private network. Do you have access to any routers that you could use to link the two machines independent of your IT's infrastructure?
The other thing to try is two other computers entirely. Again, it would be ideal to take them off the network you are on, but it's something to try if my prior suggestion doesn't work. It should work on the original two machines though, and it's likely that different computers won't solve your problems because I suspect the network.
Remember that the client variables must know the location of the variables on the server, so you can't move the server exe around without changing this value.
Make sure to set the network location in the "Bind to Source" option for the client variables.
It is also possible to write a separate piece of code to install on every machine that is responsible for deploying the library and by doing so eliminate the need for programmatically deploying the variables in the original application. However, this won't really help you, because the variables you use in the application have to be the same as the ones deployed in the library, so if you change the library, they'll no longer be linked and they won't receive data. You'd have to create a separate exe for every binding source you wanted to link to, and then have a second, known library for the sake of communication locally on the computer between the ‘deployer’ and the actual application. The main application could then be assigned the responsibility of launching the correct ‘deployer’' if it sees it needs to switch to a different variable binding source. This method is not the most streamlined or effective, but it might work.
Just to let you know, you will need to use the DSC toolkit.
Please find below some knowledge base links that I think you will find helpful in your application.
Using Shared Variables in Executables
How do I Programmatically Change the Data Binding Source for Shared Variables?
I hope this information helps and if you can give these suggestions a go and let me know how you get on, that would be great.
