Router suggestions for 10/100/1000

Anyone have a suggestion for a router that would provide 6 ports at gigabit speeds? I would like to set up 2 Express's as a roaming wireless network and have 2 desktops that would benefit by having gigabit speed and 2 network printers. If I buy a new Airport Extreme, I'm still going to need some more ports.

Thanks, Duane. That option occurred to me too. I don't yet have any devices that are "n" capable, but I always like to plan ahead, thus the desire to have everything gigabit. I guess I'm wondering if you have a favorite brand of switch. I've never been happy with my current Netgear router. For some strange reason I have never been able to use the WAP when printing to my big color laser.

Need router suggestions for G4 MDD

Wi-Fi availability is very sparse in my neighborhood, so using an iPhone at home can be challenging. I thought that by purchasing a router I could improve my situation. I would also like to control my iTunes library on the G4 through my iPhone.
The G4 is running 10.4.11 and connects to the Internet via cable modem. The G4 doesn't have an Airport card.
I would very much appreciate any router suggestions or other pertinent advice.
Thank you.

I've installed a number of routers on Mac system and they don;t have to be "Mac-compatible." I set up a network for my daughter with teh cheapest wireless "n" wireless router I could find at Fry's electronics, a TrendNet I think--about US$35 on sale. Her computer is a Mac Mini running 10.5.8 but mu old PowerBook running 10.4 connects without issue.
The easiest thing may be to ask your ISP if they have a wireless router/modem combo unit. That's what our ISP gave us. Might be a monthly upcharge if you are renting the modem but it's likely not much. Ours has wired ports as well
If you go for a separate wireless router: Typically a wireless router will also have regular wired ports. Connect the new router between the modem and the computer with Ethernet cable. The router's instruction will have a set-up section. There they will give you an IP address for your router. Type that address into any browser and you can set the options: power level; channel on some models; set a name for the Routers, and set a password (you want to protect your network with a password so people don't snipe your service or snoop).
Once so set, you can see the wireless network you've created from your phone or computer if the computer has a wireless card. If it doesn't have a card simply leave the Ethernet wired connection from the router to the computer--it will nicely co-exist with the phone.
We have three Macs and two network printers wired to our network, plus two Mac Notebooks connecting via wireless. I still have a spare wired port or two left over for when I'm servicing someone else's computer lacking a wireless card.
It probably took longer for me to type this that is would to set up a router.

Any suggestions for an all-in-one "cable modem router print server" (N)

any suggestions for an all-in-one "cable modem router print server" (N)?

If that's a problem with your cable company, change the company.
If your cable company is not able to provide you with a cable modem which gets you full performance for their service why would you bother with that company or try to make it better than them?
If you subscribe to a 100 Mbit/s service they must be able to provide you with a modem that does 100 Mbit/s and be able to demonstrate you 100 Mbit/s on your cable.
If they are unable to provide you with a modem which does 100 Mbit/s and thus cannot demonstrate that the service they have installed in fact can do 100 Mbit/s but only give you a 50 Mbit/s because that's the best they have, why bother buying yourself a better modem to find out whether or not their service does what it promises or not??
In addition, an integrated device won't get you better performance. On the contrary, consumer devices are generally single CPU (and core) devices. It's usually running some Linux or similar. If a single process gets overloaded it can drag down the performance of the whole device. For instance, let's say there is a bug in the print server software of the router. You print something and it hangs and the print server process on the router runs wild. Now the CPU is fully loaded and the routing performance will go down. If there is a bug in the routing software it will bring down the whole device and you can't even print.
You'll get the best performance if you use dedicated devices because then one device cannot overload another. Get a modem. Get a wireless ethernet router. Get a printer with integrated print server. That's far better.

Suggestions for Cable Modem and Wireless Router

Hey everyone!
I have the new iMac and would like to have a faster wireless router. Currently using an old D-Link Wireless G router and would like something like the Time Capsule (as it has Airport Extreme in it) or Netgear Rangemax Dual Band Wirless-N Gigabit Router. My problem is, my Internet is through my cable company, so it comes into the house as a cable connection. It appears that these two combos would still require the use of a cable modem.
Any suggestions to keep the equipment down to one piece? If not, any suggestions for a cable modem so I can return this old one to the cable company?
What would be the best/quickest wireless router?
Thanks for your help!

Go to your ISP's web site and do a search from your ISP for compatible cable modems. Then buy the capable modem your ISP says that is comp[atible. On the new cable modem find the Serial number & MAC address, make then call your ISP tech help desk and tell them the new modem you got and he/she will ask you that information. When the ISP tech says they can see/ping that new cable modem then it will work. Then connect a new cheaper Airport Extreme and any external USB2 hard drive to connect to that new Airport Extreme. I say this because Apple put out and Update a little while ago that will allow an external connected to an Extreme as a Time Machine disk.
PS: Remember the old trick of checking you Ethernet cables. I can't count how times I have seen professionals install all new high speed switches, routers, etc. and wonder why no speed is seen. Then after numerous trouble shooting they discover they used the old 10 Base T cables and just changing the cable solved their problem.
Just make sure you do this one at a time starting with getting the ISP compatible cable modems list to know what cable modem you can buy (to save that monthly ISP rental fee). Then you can get the going as long as so speak with your ISP tech to give them that new cable modem Serial number and MAC address so they can register it with their servers.
This will be to easy as long as you do things in step.

Suggestions for new router/switch

I have a wired Ethernet network in my office, and have been using a Linksys BEFSR81 router with it since installation. The following machines are connected:
MacPro early 2009 OSX.5.7
G5 2.0 dual OSX.5.7
iMac flat panel 700 mHz OSX.4.11 (2 identical machines)
HP 2300n printer
Brother multifunction printer/fax/copier
The router is dying and needs to be replaced. The whole network is hard wired but I could use a wireless router (e.g. Linksys WRT310) with a switch (I need at least 6-7 ports total. The selection of wired-only routers is very limited; what would people suggest for replacing the Linksys BEFSR81?

Check these pages out first on how to install. NOTE, to look for the"GL" version, as the G, GL, GS, GX are all on the same page.
http://www.dd-wrt.com/wiki/index.php/Installation
http://www.dd-wrt.com/wiki/index.php/Linksys_WRT54G/GL/GS/GX
http://www.dd-wrt.com/wiki/index.php/Index:FAQ
For the GL, you need to flash 2 firmwares initially in the beginning.
You first need to flash a mini generic (or micro); just go with mini, to the router first. Then after the mini is installed, flash the standard generic.
To easily find the right versions. Go to the dd-wrt homepage, and then look for the tab that says "supported hardware". Click on that and type in: WRT54GL (which is your router name, the one I recommended). The model GL model will show up, and click on it. There you will have all the firmwares that can be used with the WRT54GL.
There are a few different ones, but the ones you need to download are the "mini generic" AND "standard generic" (non-usb standard generic, if you're connecting through ethernet. Only if you use usb to connect to the internet then the usb version). Look at the file name to confirm.
Flash mini first, then standard second. And you only have to do this once.
Make sure to read through the above installation guide carefully, and just basically take your time. Some things to look out for are mainly just 2 things:
(1) Doing 30/30/30 hard-resets before AND after flashing.
(2) Use Internet Explorer to do the initial flash. DO NOT use firefox (maybe not even safari). This is only for the initial flash with the linksys firmware on. Once dd-wrt firmware is on, any browser will do. This is in the install guide, but basically any PC with IE will do fine. If you don't have access to a PC, you can even use the "old" IE for mac. That will work too.
Again just take your time, read things, and double check them. It's actually a very easy process after you've done it once.

Should I always let my iPad 3rd generation die and charge ? Takes almost close to 12 hours for a 100% charge. Any suggestions ? iPad is over a year old

Should I always let my iPad 3rd generation die and charge ? Takes almost close to 12 hours for a 100% charge. Any suggestions ? iPad is over a year old and don't want to buy a new one if this problem will continue to happen. Help

Do not let the battery drop to 0%. That is very damaging for a lithium based battery, as in the iPad. Charge at any time, for any amount.

I started to have connectivity issues with a linksys router. The linksys rep suggested ...Check from Apple if they have some particular ports for the Apple TV that we might need to open on the router, anyone have any suggestions for this?

Creating a 20MB bandwidth using two cisco asa 5515x with a hub (10/100/1000)

hi all,
I would like to simulate a bandwidth of 20MB for my DR project testing on my two cisco asa 5515x and with a cisco hub (10/100/1000). I was thinking to make two connections on my "outside" vlan with both speed of 10 and etherchannel it and do it again on the other asa.
Do you think it will simulate 20MB bandwidth? Or any other suggestion? Please add any comment, thanks to all.

Hi Nicholas,
You have the HSRP running between your core devices. You can have your core A - ASA1 & Core-B - ASA2.
In your core switch you need to have a sepearate VLAN to connect the uplink to the firewall and asusual in asa you can have the primary and standby address configured and in core also you can have the vlan with hsrp ip configured.
But make sure that in your firewall you should mention the static routes for each subnets pointing to the core device hsrp.
The other scenario is you have make you ASA a standalone firewalls and in one firewall you need to have route to core a as primary and core b as secondary and in the other firewall vice versa. So that your traffic will get load balanced.
Please do rate if the given information helps.

Difference in speed btw 100 & 1000 ethernet

I'm considering wether to buy the Apple wifi 802.11n router. It has 100 ethernet ports only. How much slower is the speed btw 100 on the apple router and a Linksys 1000 router?

Hi,
I spotted this thread, and thought it might be appropriate to ask my question here.
I know I must be a bit of a dunce, but are their any ways to make sure that the ethernet port on my PowerPC iMac are set to work at the correct speed?
I ask, because I am having a problem with my cable broadband connection with my iMac. I have a 20MB connection, and when I use my 4 year old Win XP system I can achieve great speeds up to around 15 - 17 MB downloads speeds.
But on my PowerPC iMac, I can hardly get above 2MB download speeds.
My service provider has confirmed that my connection is working fine, and they have replaced my five year old cable modem, but still this problem persists on my iMac.
My Service Provider suggests that I check that my Ethernet port is set to receive 100MB+
Can you advise, or anyone else put me in the picture.
I am using a an Ethernet cable connected directly to my cable modem, and the Ethernet socket on my iMac.
Thanks

Is there any suggestion for the "SafeNamedCache was explicitly released"

I deployed the coherence-java-3.6.0-java on red had with core 2.6.18 with 64 bit.
Then the deployed the coherence-3.6.0-cpp on the same manchine and complied the example "hellogrid" and it works ok . No any error .
My requirement is to integrate the Coherence into the Nginx0.7.62 for my web server . And i wrote a thread pool for the NameCache::handle and get a newly hendle after a 5 seconds just because of the error "was explicitly released" . But it is not useful for solving the problem .
Anybody please give me a suggestion for the root cause of this problem .
Thanks .

ESW 540 24 10/100/1000 POE Firmware upgrade

It seams a new firmware was issued on the cisco download site on january 11 :
ESW_540_K9_2.1.16.zip
I have succesfully downloaded this file, but each time I try to unzip it, I get an error.
I have tried to download it several times, using different navigator and different pcs or macs and using the donwload manager or without it, and I get the same result.
Also the md5sum of the downloaded file is the one indicated on the download screen :

First call attempt fails with 12000; reason="Routes available for this request but no available gateway at this point"

We've installed a new Audiocodes Mediant 1000B gateway for our customer. They only have about 6 users enabled for Enterprise voice and using Lync for all calls. They have an intermittent problem whereby the first call attempt to a number on the
PSTN fails with 12000; reason="Routes available for this request but no available gateway at this point". There is only one PSTN gateway installed. All routes point to this gateway. What I found initially is that the calls
were failing after 10 seconds which is the default "failovertimeout" in the OutboundRouting.exe.config. I found this post http://voipnorm.blogspot.co.uk/2012/06/lync-2010-gateway-timeout-call-failures.html and
changed the value to 20 seconds. Subsequent failures failed after 20 seconds (the new value). The interesting thing is that the second attempt even a couple of seconds later succeeds. My Lync server event log has 46046 "A call to a PSTN
number failed due to non availability of gateways." for the failed call and 46047 "A PBX gateway is now responding to requests after some failures." for the successful call moments later.
My environment is Lync 2010. A single enterprise edition Front End with collocated mediation. The server is virtual and in a different physical location to the gateway. The two sites are connected via a LES1000. The RTT between the
sites is very low so it isn't necessarily networking.
In the Syslog output on the Audiocodes we don't see the call even reach the gateway. It's likely that Lync has simply marked the gateway as down and doesn't route the first call. Then it wakes up and marks it as up and routes the next call.
Update wise I'm on 4.0.7577.183, 199 and 217 for those that are up to date and the only components that are behind say that 223 is available. Those being Core Components, Lync Server, Conferencing Server and Web Components.
As I said, this is intermittent, apparently doesn't happen for every user (which I don't buy), but is easily replicated on request.
I definitely think changing the failovertimeout value has reduced the number of failures. But realistically I don't want users sitting there for 20 seconds before their call fails. Or 19 seconds for the call to route.
I've found a few posts on this and similar issues. I don't get the 25051 or 25052 errors.
Any help gratefully appreciated.

Randy Chapman

What kind of antivirus do you suggest for mac OS X Maverics?

What kind of antivirus do you suggest for OS X Maverics?

OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Any suggestions for building a home network (in a modest 1600 sq. ft. home) with the following requirements...
1) Laptop(s) and PC share broadband (cable) internet connection
2) Access files on PC from laptop(s) and vice versa
3) PC and laptop(s) share printer (Canon Pixma 610)
4) Send media on PC to TV
5) Send music to wireless speakers (not purchased yet)
Note hardware specs:
A) One laptop runs on Windows XP and has an Intel PRO wireless 2915ABG network connection
B) PC runs Windows XP Media Center
I was thinking about the wireless N broadband router 300. From the experiences of the community, will I be able to achieve my goal? Beside a PC adapter, is there any other hardware I will need?
A couple other questions.
The router will likely be sitting right next to my PC. Does the PC need to have a wireless adapter or can it be wired from the router to the PC?
When will the media extender be available? Will it work with Windows XP?
Thank you.
Chris

I personally might not buy Wireless-N, but the idea of being on the bleeding edge is nice.
Anyway, whichever router you choose, you should be able to accomplish almost everything you need.
You'll be able to share your internet amongst all of the computers, and share files between them all. Local firewalls and permission settings on individual computers could potentially pose a problem.
Sending media to your TV may or may not be possible, depending on what other hardware you have. A router itself would not be able to do that, as a TV doesn't usually have any form of WiFi, but if you had a box connected to it for displaying content on the TV, you could do something like that...
Wireless speakers are generally a separate wireless system. As far as I know, there is a wireless transmitter that sits next to the amp (or other sound source), and broadcasts the music wirelessly to the speakers. You'd have to make sure the speakers and wireless router are on different channels as to not cause interference.
Don't know much about the media extender, but highly likely will be compatible with XP.
