Networking help needed, I want to run two routers on my lag

So I have this problem (https://discussions.apple.com/message/17067869#17067869) and I am thinking now that maybe there is something in the broadband company supplied router that is amiss. As I have plenty of other routers lying aroung, how do I do this: Just use the ISP router to get internet into the room, and use another router to set up the LAN network, so I can isolate the problem somewhat. Is this possible? Turn off the DHCP server in main router, and turn it on in the second router, while plugging the second router into one of the ports on the main? Not too sure about that thx.

Had a look at your other thread and really could not make any sense out of it.
If you can put the ISP supply Modem/Router combo box into Bridge Ethernet mode then you can connect your own router as the LAN DHCP server and default gateway to the internet.
You don't say what the ISP router is, whether you are on a DSL or cable or some other type of connection from your ISP. You also don't state whether the modem you have from your ISP is really a router or just a modem.
In the states most Cable ISPs use bridged modems handing out a public IP to the piece of equipment connected to it. These are single Ethernet port boxes and will usually assign just one public IP address. But there are some ISPs, and services like for businesses, that do allow multiple public IPs.
What is the IP address of one of your computers? If it is in the 192.168 or 10. or 172.x range then you have a modem router combo box. It the IP is in any other range then that box from your ISP is just a bridge modem and you need to install a router.
If the IP is in one of the ranges I listed above then it is more then likely a combo box of modem and router. In that event adding a second router will cause what is called Double Natting. which isn't a good thing to do.
Also some Cable ISP in the states have gone to installing there own router somewhere in the loop of connections and they do hand out private IPs through a bridge modem. That way they don't have to buy more public IP address space, which is running out.
So a little more info is needed.

HELP...want to merge two itunes accounts into one running several ipods

Hi, I need advise as I have two Itunes accounts for my family running on tow different laptops with win7 and with two iphones and two itouchs. I do I merge all this into one account that I can access from all devices and all computers?

Do you have a home network? You can set up itunes Home Sharing and transfer your purchases that way. You need to authorize each PC for the two different STORE accounts to transfer each account's purchases.
If you don't have a home network you'd have to use an external hard drive or USB stick.
Long story short, there's no automatic way to do it. You need to keep track of each account's purchases and what PC they are on, then move them to the PC that is missing those items.
There are some 3rd-party programs like Tune Ranger that say they will keep everything insync from one PC to the next, but they cost around $20 or $30.

Want to run two 30" cinema displays from Mac Pro

I'm running Avid Media Composer software to edit a film that I made, and I would like to run (if possible) two Apple 30" cinema displays next to each other off of my Mac Pro (the computer was purchased at end of 2009). While editing with Avid software, I like to spread out my work and bins in able to see everything, and strange as it may sound, I'd like more room than one 30" display can provide. Currently, I have one Apple 30" Cinema display in use, and could purchase another large display if I can find out-- definitively, if my Mac Pro computer will be able to handle it and power it effectively. I realize that Apple doesn't sell the 30" displays anymore, but I saw a few relatively inexpensive ones available on Craigslist recently.
The second monitor that I'm using now is a much older (non-Mac) monitor (and smaller) and the resolutions don't match the high resolution of my single Apple 30" display. So, my reason for wanting a second, larger display are twofold... 1) to see more of my work, and 2) to get the highest resolutions to match (2560x).
The ports on the back of the Mac Pro don't look like they will support the use of a second 30" display, just one. Does anyone have any suggestions?
Do I need to purchase another video card to run a second 30" Apple display? If so, which ones are best/do you suggest?
Do I need to upgrade my processing speed (get a faster processor) to run two large, high-rez monitors?
specs:
Mac Pro
10.6.6
Processor: 2 x 2.8 GHz
Memory: 2 GB
800 MHz DDRZ FB-DIMM
Quad-Core Intel Xem
Purchased end of 2009

If it has two DVI ports, just plug in the second display with an additional Dual-Link DVI cable -- the card can run both displays without issue.
If it has one DVI and one other type, Exactly which display card do you have installed?

Clueless with networks, help needed!!

My current configuration (with problems, mentioned below) is... computer (ethernet port) wired to a Lynksys router. From router (wired & I don't mind the wires), extensions to... a) cable modem, b) printer 1 (via asante), c) printer 2 (via asante), and d (newly configured and probably wrong) airport extreme w/APPLE TV). I had airport express with airtunes (which I would like to keep). Finally... I have airport card (what does that do?) Before the airport extreme (&ATV not linked with tv yet) everything worked fine, however now- airtunes blinks amber and only sometimes works, airport tells me I have 2 networks running. Diagnostics tells me the airtunes IP address missing. Apple TV light is green however I can no longer print (tells me appletalk is not connected, however if I connect... airtunes music stops). So basically... 1)How should this be configured? 2)What does the airport card do? 3)Do I have to have multiple networks? 4)How can I get airtunes to play, and my printers to work simutaneously) 5)Can everything be on just one network (and run correctly)?
Thanks, and yes I am clueless regarding networking

What you need to do is configure the "Airport Extreme" as your "main" wireless access point. Then configure the Airport Express to "join" and/or "extend" the network you created with the Airport Extreme. That way, you will only have one wireless network and your computers will not get confused. If you have the new airport, the linksys router is not really needed because the airport will serve as the router/hub. If you have the "old" airport base station, connect it to a LAN port on the Linksys router and configure it to serve only as a wireless access point and "print server". Otherwise, you will have two routers "competing" with each other. Set up and configure one device at a time.

Wired network help needed

hi i'm new to support communities
this is my Question:
i want a wired network for the 2 mac's and the pc desktop, the router is in the hallway and the 2 mac's are in the living room so my idea is to run a cat6 ethernet cable to an airport extream base station and 2 ethernet cables to the mac's and get a usb hard drive for all my muisc and tv programs, movies to share on the network so i can stream them where ever i need it . then run ethernet cable's to my son's bedroom and our bedroom and so we can run apple tv in our bedroom via airport express wired to apple tv and make wifi better as well for all wifi devices. i prefer wired network as it's faster and more reliable.
so i was going to buy a 5th gen apple extream x 2 and an airport express latest one.
would this be a good setup any help would be very welcome. many thank for your help
mac mini 2012 i7, imac, window's 8.1 pc (son's), iphone, sony z1, apple tv (not setup yet), now tv box,

A very good plan to use an Ethernet "backbone" for the network, which will result in much faster and more reliable performance.
The 5th Gen AirPort Extreme was discontinued in June 2013.
The 802.11ac version of the AirPort Extreme offers quite a bit more performance, even if you do not have 802.11ac devices at the present time.
Apple added two additional antennas in this version and moved all of the antennas up to the top of the "tower" for more efficient broadcast operation.
The 2nd Gen Express would really limit performance since it uses 100 Mbps ports. Your Ethernet cabling and the AirPort Extreme model that you choose offer Gigabit or 1,000 Mbps ports. The numbers speak for themselves.
If the budget allows, two AirPort Extremes would be the way to go.
Apple tends to introduce new models in June of most years, so if you are not in a rush, you might want to wait and see what might be coming soon.

Help needed - i want to buy the lenovo a720

Hi
-i plan on buying the lenovo a720, but a720 is generally being sold with windows 7. so when we upgrade to windows 8, are there any compatibility, bugs or drivers issues that occur? i mean to ask is that does it run perfectly with windows 8 or not? im asking because it was released before windows 8 and i have read many pre-windows 8 computers not being fully windows 8 compatible and having driver issues etc....
-secondly when i buy it, i will have to take it to Pakistan on plane. so i was wondering if is it is possible for someone to kindly tell me the exact dimensions (length, width, height) and weight of the box in which the A720 comes in? because il have to carry it in my luggage so i want to know the exact size to be sure that whether il be able to carry that large box or not.
i have tried contacting lenovo but to no avail. i sent emails but didnt get a reply. can someone plz help?
thank you in anticipation !

Go to Solution.

Hi Ehsan,
I bought a720 at the beginning of October and installed Windows 8 on a separate partition (now I have Windows 7 on C: and Windows 8 on D: ). Windows 7 works perfectly on this machine. Windows 8 has multiple issues with device drivers. I downloaded and installed the latest drivers from Lenovo's web site. Still there are many issue (OSD, TV Tuner, touch interface seems to be limited, and so on). I'm working mostly in Windows 8 however and I like it very much. So these issues aren't showstoppers. Also, it is very probable that the device drivers will be updated soon.
The box dimensions are the following: 770 x 520 x 195 (in millimeters). The gross weight is about 15 kg.
If you don't need to buy something immediately I would rather recommend to wait for the a520 machine (not b520 !). According to its specification, the a520 machine will have better display matrix (IPS) in comparison with a720. It's display size is lesser however. One big advantange of a520 is that it will be shipped with the preinstalled Windows 8.

IPhone 4S - Could not scan for wireless networks - help needed please

Hi
Can anyone offer any advice please.
My 4s has developed an wifi issue. It cant scan for wireless networks My bluetooth is intermittent also.
I have turned it on/off, rebooted, reset all networks, reset to factory settings, set to airplane mode, set to do not disturb - everything and all to no avail.
I am under a two year contract with Vodafone and went into their branch at Merry Hill, Dudley today and they failed to help me saying it was nothing to do with them.
I am at a loss as to what to do. I have not had any accident with my phone and it is still in mint condition.
Can anyone please offer any suggestions on what to do.
Many thanks.

Apple's out-of-warranty policy is a feeble attempt at covering up it's issues and is a clear cut demonstration for their lack of respect for its user base. Their WIFI/Bluetooth dropping issues have been around for several years now and it started within the last 3 IOS updates. Apple engineers acknowledge this problem and don't have a solution yet... this was confirmed at the Genius Bar at their Nashua, NH outlet. My phone is 6 months passed warranty and my Verizon contract isn't up for renewal for another 6 months.
There are a lot of complaints about this (a LOT), yet Apple continues to stick its head in the sand instead of owning up to providing shoddy hardware and/or glitches software. They certainly don't want to be in the business of replacing phones, so they put the onus on us by charging $200 for a replacement... such a deal for Apple!
Apple's support communities are basically useless on this subject with a lot of screwy so-called solutions to work around their flaws. I've seen one fix where you heat up the phone with a hairdryer until the temp warning appears and then refrigerate it for 10 minutes... then BINGO, it's all fixed! Ya right!!!
Resetting network settings, or all settings (including a complete reset) is ineffective and appears to do nothing more than to further upset Apple users once they realize that they have wasted their time following Apple's so-called fix.
I just wonder if or when Apple pulls it's collective head out of the sand will they be able to see that their competition has surpassed them by leaps and bounds. There really isn't any good reason to stick with Apple now-a-days since their conscience passed away. Their competition offers superior technology while Apple continues to impress up with new connector technology and placement of their sockets.
I am finished with Apple and am incredibly sick of their spoon feeding what they want rather than what we want.
The best way to make Apple improve is to provide them with a taste of their own WIFI/Bluetooth offerings by DROPPING THEM!
They have abandoned us and have no problem trying to charge us to replace their flawed technology instead of doing the right thing!

Help needed in Automatic payment run

Good afternoon, i want to create a payment run and use Special GL aslo... i have assigned in fbzp--> all co. codes and special gl "A" but according to my client he is asking that Special GL"N" should aslo be allowed for Automatic payment. but when i assigned Special GL "N".. its shows a error "Payment is not possible for special G/L indicator N" Message no. F3072... Please help me as N is needed as Special GL indicator...
Regards,
Abhay

Hi Abhay,
Let me first clarify a note item. A noted item is only for information purpose in the system and has no financial impact.
Meaning say you have recd a post dated cheque from a customer and you post in the system, it is a single line entry, though you can see it in FBL5N, when you select note item on the selection screen, but in real world you financial impact is same and has not gone down by the posting on noted item. You can just track in the system how many post dated checues you ahve in hand.
Now, coming to your scenario, you are saying you posted a noted item of 2000 from Special GL "N". You are also mentioning that Vendor liability is Rs. 10000/- and then you say balance is Rs. 8000/-.
It cannot be.. if it is a noted item entry, balance would still be 10000 which need to be paid to vendor and even APP will pick up 10000, irrespective of whether Special GL N is specified in FBZP or not and this is what system is doing.
I am again requesting you to write the scheme of entries at each stage with amounts.
Regards,
Kavita

Networking help needed

Hi,
I have two types of clients, a and[b] b, that need to pass messages between each other.
Type a are searching for a suitable client of type b to begin communicating with.
A server keeps a record of who has joined, and allows type A to look up type b in a shared datastructure.
- a >I want to talk to a[b] b with x characteristics.
- sends request to server.
- server looks up in a shared datastructure sellers with this characteristic, and returns to a any that have this
- a selects which out of the results returned from the server it wishes to communicate with
- a then begins to communicate with the selected b, ideally I'd also like the server to check that the communicated messages are reasonable and within certain constraints... but I could avoid this and have the clients talk directly with each other if its a lot easier.
So I have a basic understanding of what I need to happen, but I really don't know how to go about doing it.
Does anyone know of tutorials explaining the best way to do this?
Thanks!

I understand that you need to develop some sort of client server based application.
Before you get into thick of the things, you need to know what are requirements and what Java can offer.
Add to that already available frameworks mostly opensource in abundance.
You can probably use JDK to code the entire application (client/server). But in that case you would have to take care of threading issues etc.
Or you can use a webserver to host the business logic(rules of who finds what and finally interacts or not) of your application(eg:- tomcat could be the webserver/container- you can have servlet(s)/JSP to handle the clients) to make the business logic better you can also use struts framework to design the server part of your networking quandary.
The message between the server and client could be HTTP(I could think of that or you might have to come up with your laws for interaction between the client and server).
Using a webserver for this has its own stigma attached(like performance) but it would almost erradicate the issue to handle multiple clients etc.
This could be one of the worst suggestions.
Cheers

Home Networking help needed.

All: I am refinishing the basement and installed some ethernet to 2 walls. I outlet for a TV (when I buy it) and another for a PC (for if the resident needs it). I also want to have my wireless from upstairs be a strong signal.
So I need to know the device that will:
1) Pick up my existing wireless signal and repeat it for the basement rooms wirelessly.
2) Have 2 ethernet ports available for the hard wiring I put in.
The location for this in the drop ceiling has an 110V outlet readily available next to it.
Can someone guide me what I need to purchase to complete this and test the wiring (connectorization) I did?
Thanks a ton: Ed

I tend to like Ubiqiti (http://www.ubnt.com/ ) products but they can be difficult to find. These are dedicated APs, they do no routing and you'd need to also get an Ethernet switch (any old switch will do) to take the one hardwire drop from upstairs and provide a few wired ports (2 for the walljacks and 1 for the AP) downstairs. I linked to a switch below.
Also nearly any wireless router can be reconfigured as a combo AP/switch, in which case I'd just reccommend something with stable firmware. (This can be hard, you just have to read LOTS of reviews, or find something on the DD-WRT compatibility list and flash the router with that firmware. Note that DD-WRT will void a router's warranty, but if you put it into a cheap router it's usually worth the risk.)

According to CMSInitiatingOccupancyFraction=60 , GC should work when reaching 60% of the memory. But that's not happening instead memory consumption goes above 4GB then GC works and memory comes down to 500MB ,during this our GUI screen hangs for few seconds.
Could somebody please help me in this ?

I'm not as familiar with tuning the hotspot VM as i would like to be so the following may well be things you have already tried. If i had an extract from the GC logs that would probably help me visualize what is happening under the covers.
With CMSInitiatingOccupancyFraction=60, a Major GC will kick in when more than 60% of the tenured generation size is in use. Based on your description that appears to be the case here, if you set this to the default (92% iirc) does this help any with the pause or is it basically the same?
You may want to take a look at http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html (the "Starting a Concurrent Collection Cycle" section).
This could be one of those cases where the heap is just too big (probably not if you have 8 cores working through it) or it could be that you have in-flight threads that need to be brought to a safe point prior to processing and your CPU is pinned (what was CPU looking like before/during/after the GC cycle?) see:- http://mail.openjdk.java.net/pipermail/hotspot-gc-use/2011-August/000915.html
It might be worth investigating the use of UseCMSInitiatingOccupancyOnly (consider not using it see if that helps) http://docs.oracle.com/cd/E19543-01/820-2962/Performance_Tuning.html#wp1265817

Please Help~Need to swap data between two 2010 MacBook Pros

Ok I have a 13" mid-2010 MacBook Pro and my wife has a 15" i7 2010 MacBook Pro. I need her MacBook's processing power to start doing some short videos for our church (After Effects, Premiere). She prefers the lighter 13" anyways so we've decided to swap. I've made two "complete" backups onto a partioned external hard drive using the software, Carbon Copy Cloner. My objective is to swap all data AND settings from one to another and vice versa. She has very important settings on her MBP that cannot be lost. What is the best route to take from here?
Thanks in advance for your advice!

Pretty easy, using the original Install Disc that came with each computer restart the computer while holding down the Option key. Choose the Install Disc to boot from. Then choose the language and next choose the Utilities Menu-Disk Utility. Once you are in Disk Utility choose the internal HD of the computer-Erase tab (ensure it's set to Mac OS Extended (Journaled)-Erase. Once the erase has been done then exit Disk Utility and continue with the installation. At the end of the installation it will ask if you want to restore from a Volume connected to the computer. Choose that option and choose all the options and within a couple of hours the machine will look and act like your old machine. Do the same with the other computer and you're done with the swap.
