WRT54G V8 Dropping wireless connection

Hello,
I have an issue with my Lynksys WRT54G V8 (firmware upgraded to V8.00.2). No problem whatsoever with wired connection, however, it appears to drop my wireless connection every 10 or so minutes. I appear to be able to connect to my neighbors unsecured connection with no problem however. The only way I can figure out to reconnect is to power the device off and on again. Disabling and enable the wireless adapter on my laptop does nothing.
Here is what I have tried:
I have moved the device to be closer to my laptop (it is now approximately 6 inches away).
I have changed the channel to be 11 instead of default 6.
I have changed client lease time from 0 to 999
I have upgraded the firmware to 8.00.2
Verified that my SSID is unique
This is the 3rd wireless setup I have done (separate places, 1 office and 1 in my home and this one in my vacation home). This is the first time I have had any issues. It is the same laptop, I have the same model of cordless phone in my home as the vacation home. The only thing I am not sure of is the firmware level of the other two devices. They are the same model.
Any suggestions before I return this device and buy another model?
Thank you

After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since the last firmware upgrade, please do this now, and see if it corrects your problem. If you saved a router configuration file, DO NOT use it. If the above does not fix your problem, then read on:
There are many causes for poor wireless connections, and many solutions:
Set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
Also, you did not mention what type of encryption you were using. If you are using WPA2, or "WPA with AES" (= WPA2 ), then note that Windows XP requires a patch to run WPA2. Go to Microsoft Knowledge base, article ID=917021 and it will direct you to the patch.
Sadly, the patch is not part of the automatic Windows XP updates, so lots of people are missing the patch.
If the above does not fix your problem, download and install the latest driver for your wireless card.
If you continue to have trouble, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps. For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
If you still have trouble, download and re-install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

WRT54G keeps dropping wireless connections

Wired connection to the router works fine. But it drops all the wireless devices (PC, phone, tablet) multiple times each day, sometimes only 30-60 minutes after reconnecting. Power cycling the router "fixes" the router and allows reconnection. There are 2 topics in the FAQ section that looked helpful:
Getting poor or no signal from a wireless router
Top causes of dropping wireless connection on a Linksys router
but clicking on those does not bring up anything. Anyone know where to find those 2 FAQs? Any other ideas for what might be causing this?

Hi. You may need to do firmware upgrade on your router as is the case these days for legacy routers. What is the hardware version by the way? You can find it at the bottom of the router right after the tiny print of the model. Access homesupport.cisco.com and search for the model. When you get the router's page click downloads below support sections and from there you have to select the hardware version, once you do that you will see the firmware version for the said hardware version. Usually it is a bin file when you save it and you can open that one on the router's page. Once you access your router's page go to Administration and click Firmware Upgrade and select the file you downloaded from the website. Make sure that you do this upgrade with a computer plugged-in to the router. When upgrade is done, you do a 30-second reset and unplug/replug the router also for 30 seconds. You may refer to this link http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&vw=1&articleid=4030.
As for the link for Getting poor or no signal from a wireless router, I found this one from Cisco's public kb site but not able to for the other one but I believe they are related.
http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=d9a3b1b2039741948a2365b053a93ea8_3759.xml&pid=80&r...
Try to change channels as well on your router: you can try 1,3,6,9. Make sure the router is placed at least 3 feet above ground and check the antenna as well if it is still okay.

E3200 - Dropping wireless connection on the Mac

Pros: Gig Eth switch, no front-facing indicator lights, familiar web interface...
Cons: WiFi Protected Setup doesn't belong. Continually drops wireless connections to my Mac Book Pro (but none of my other devices), which worked just fine on the E3000 this unit replaced and works perfectly on other WiFi networks. REALLY SLOW web interface - average time to move from one page to the next is something north of 9 seconds. Again, never a problem with the E3000 that this unit replaced. Price? I wouldn't complain about price if this thing actually worked as expected.
Other Thoughts: I'm hoping it's just a flaky/defective unit and not indicative of the overall quality of newer Linksys products. Firmware isn't the issue - it's running the latest one from Linksys' site.

First of all please verify that you have got a 802.11n card in your computer. New generation routers (i.e. E3200) speaks an entirely different language with 802.11g cards, so while those adapters can work with the E3200, but they are not optimized to provide good performance. It is like having to translate from one language to another in real time when going from N to G.
Well, there are few things you should keep in mind with regards to N routers:
1) For the best possible speeds, you need to be using WPA2-AES as your security mode. Any other security mode will see your speed/range capped.
Any G devices in your wireless network will tend to hamper the performance of your overall network.
Ensure that your router is running the latest firmware from homesupport.cisco.com The new firmware includes performance enhancements and fixes.
The router by default uses a channel setting of auto, which means that it would keep switching channels depending on the interference. I’d recommend you set it to a fixed channel. Usually, 1, 3, 6 and 9 give you the best performance depending on your environment of course. I’d suggest you try different channels, observing each for a while, to see which gives you the best performance. You can follow the link here on how to change channels.

WRT330N Dropping Wireless Connections

I have a WRT330N which I have been using for a while with a couple of wired connections and 3 wireless connections.
It has been working great for months, but has suddenly started dropping wireless connections. I basically haven't touch the thing since I set it up and it has worked flawlessly.
Any idea why it would suddenly start behaving this way? Nothing else about the environment has changed either.
Could it be dying?
BTW, it will drop connections with a system literally sitting right next to it.. so distance isn't an issue.

Try to upgrade the firmware of the router .
And also do not use any electronic devices in the range of router .

WRK54G dropping wireless connections

Hi,
I have a WRK54 firmware Version 1.56.01
It keeps dropping wireless connections and can't get back on, requires restarting (power) the router to allow wireless working again.
I have set the MTU to 1300
Doesn't allow me to update the firmware, error "Upgrade action is not finish!! Upgrade file pattern error."
Using Windows XP SP2
Any ideas?
Regards,
Sercan

Are you trying to Upgrade the firmware on your Router from your Wireless Computer? If yes, then you can Hardwired your computer to the Router using an Ethernet Cable and then try to upgrade the firmware of your Router....
If still you are Unable to upgrade the firmware on your Router, then you need to Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable..... Now you can try to upgrade the firmware on your Router.

WRT54G dropping wireless connection on laptop

My laptop (WinXp SP2) is frequently loosing it's wireless connection to my WRT54G router. It seems to happen on a random basis. Sometimes, I'll boot the laptop and I'll have my connection, sometimes I won't have it. When I have the connection, I may loose it for no apparent reason. It may happens even when my laptop is near the router. There's no wireless phone close. Microwave is not working. I'm in an appartment so it might be a wireless channel problem. I have yet to try that.
I have the lastest firmware upgrade (8.00.2). I have activated WPA2 security and MAC filtering. I'm using aes for WPA entryption method. Naturally, I have downloaded the microsoft patch for WPA2 on the portable. I have tried to change the MTU size to 1498 instead of 1500 to see if anything would change. From my tests, the default value was right on anyway. I have tried without WPA2 security (just MAC filtering) and I still got the same problem.
I also have a Wii which is connected wirelessly to my router who experience the same problems. My desktop computer is wired connected to my router and never has any problem. So it's really just a wireless problem.
Has anyone experienced a similar problem?
Thanks

try to change the wireless channel, you could choose from 1-6-11 i suggest 11...and try to check the advnced wireless settings set the beacon interval=50 fragmantation threshold=2304 and RTS threshold=2304
with the mac filtering that you have make sure that the MAC addres of your wireless computer is properly saved there...

Wrvs4400n keep dropping wireless connection

hi there,
has anyone got problem with wrvs4400n keep dropping the wireless connection? i tried to find out anywhere but not much hints are given how to solve the issue.
i have 1.1.03 firmware installed, and currently running on
b/g/n mixed on channel 9
wpa2 personal mixed security
the rest of the settings on default
i had the router running for about 3 months and most of the time i have to either restart the server to get the wireless working again. normally the wireless works ok until few days when suddenly I just can't access the internet using the wireless.
once i replug my computer using cable, the wireless router suddenly can give me IP address and the wireless return back to normal.
i have tried to use
different channels
changing to G/N, and B/G mode
change key renewal frequency
reduce RTS Threashold
accessing the wireless router from 3 different wireless network card
none of them really works, normally after few days, 1 week top, i suddenly lost wireless connection again. the SSID still there, i can authenticate, somehow the wireless just won't give me IP address
checking the website, it seems like i'm on the latest firmware from linksys and they don't seem updating the firmware anymore, is this product not supported anymore?
anyone knows of the same problem ? or has already solved the issue?

Hey Stewey,
I have a similar problem with my iMac G5. My roommate, who has an HP, bought a Linksys WRT54G when we moved in to our place and it gives me trouble with Airport sometimes. We use G only and WPA Personal. I updated the firmware in February and I swear it got a bit better, but it still goes out sometimes. If I move it just a few inches in any direction, generally it will start working again. Resetting it also helps sometimes. I don't know if its the fact that it doesn't say it's compatible with any Mac on the box, but it's annoying as all ****. My roomie rarely has problems with it (our rooms are the same distance away from the router), but my friend brought his PB over to do some work and he had trouble in my room as well. Is it Linksys, or is it Airport? I have no idea. Our router is out in the living room, next to the TV and Xbox 360, so it might be interference. If possible, try moving the router to higher ground and away from other electronics.
I tried looking up your router online to see if I could find anything else out. Didn't find too much info, but it says that you get free 24 hour tech support. You don't see that too often. If you can't figure it out, give them a call.
Good luck!

WRT320N & IBM T42 laptop keeps dropping wireless connection at key times

I have an IBM T42 laptop whihc keeps dropping the wireless connection at what seems to be the same time windows each day.
I have my cable modem connected to my WRT320N.
My wireless it set up as follows :
Manual configuration
Wireless Band = 2.4Ghz (Think it needs to be this for the T42 wireless).
Network Mode = Mixed
Channel Width = 20Mhz only
Channel = 2
It seems to be that at approx 8pm each night when using the latop downstairs, the wireless connection will drop and then fail to reconnect for a period of time. I reboot the laptop and it will then begin to work again. The wireless connection does seem to keep trying to connect but it cannot maintain the connection to the router.
Any ideas?

Well I've pretty much given up trying to get this router to work so have spoken to the supplier I bought it off who said it's now discontinued by Linksys - all support is through them now. Took it up with them went through all the steps I've done to try and troubleshoot it (helps to be an IBM engineer as I logically follow procedures through).
I've RMA''d the router and hope it's replacement works better. I've just unbricked my old WRT54GS to make do whilst I wait for a replacement - back down to 100mb traffic - I'll miss my gigabit switch for a while!

Time Machine Causes MacBook to Drop Wireless Connection

Recently I started having tons of problems with my wireless connections (dropping after a few minutes, unable to reestablish)
The fix was to turn off Time Machine.
Help! How can I use time machine on my computer without it causing me to lose my wireless connections!
This affects my computer no matter what network I am on. As soon as Time Machine starts the backup I lose the connection to the wireless router.

Satellite U920T - dropping wireless connection

My Satellite U920T seems to sporadically drop its wireless connection and reverts to 'limited' connection which provides no internet access. This is the case on both my home and work wireless networks.
Can anyone offer any advice please?
Thank you

Do you use original preinstalled OS that you got with your notebook?
Is latest WLAN driver installed?
Is the situation the same when you use it with battery or AC power supply?
For testing purposes have you tried to restart your home router and check if the same will happen again?

T41 dropping wireless connection

I've had nothing but trouble with my T41 wireless connection.The model number is 2374-3HU.
With Windows XP installed, my home wireless connection (which has excellent strength) would drop intermittently. The network would not be found and I would pull my hair out over this. I wiped out XP and installed Windows 7, hoping the problem would go away. No such luck.
The first time I set it up, the network was found and ever since then it comes and goes but I am never able to connect to it. I have a Toshiba connected to the same network and have never had a problem with it.
Are there any firmware updates that can be applied to resolve this very frustrating problem?

Hi itmanager8815,
Unless i'm wrong your computer got the Intel 2100 3B wireless adapter?
If that's the case i would only recommend to replace the mini PCI wireless adapter since i had some really bad experience with those adapters as well as some other old Intel wireless adapter in the past.
I would say that the 2100 3B mini PCI adapter is basically useless. At the time when i had a Thinkpad T40, T41, T42 and T43 i replaced the Intel wireless mini PCI adapter with the Thinkpad Wireless (Atheros) and it worked a lot better. I also had a lot of disconnect issues with the 2100 3B and 2200bg. The newer Intel wireless adapter like 5300 and 6200 i find to work great though.
I don't know any solution to fix the problem with the 2100 3B since i tried in the past without success.

WRT54GS v7 loses wireless connectivity after 15 minutes or so

I just installed a WRT54GS v7 router to work with my cable modem. It has the latest firmware. The wireless connection seems to work for about 15 minutes or so at a time and then it stops working. I can't even get to 192.168.1.1. The only way to get it to work is unplug the router and plug it back in. Originally, I thought it was interference from my 2.8GHz cordless phone, so I unpluged it. But that still didn't fix the problem. What could be the problem? Thanks.

Macbook keeps dropping wireless connection

Hi
this is my first post so be gentle with me LOL
I have had many issues with BT over the last 8 months, mostly due to the speed I had in my area (was 0.45MB when wired at one point), but I recently started to have an issue with the laptops in the house.
I have 2 teenagers and luckily for them we all have Macbooks as I have given them my old ones when I have upgraded I am using a macbook pro (less than a year old & wireless N) and my eldest boy is using a Macbook (about 6 years old with wireless G) you might see where I'm going here....
the problem is the older macbook keeps losing connection on the wireless, I have called and spoken to the 1st line support guys in India but it's a bit of luck if you can understand them let alone find someone who knows what they are doing. As I work in IT I completely understand and normally ask them to read my notes before advising me especially as I had so many issues last year when I was given a number to get through to the priority care team LOL , so far I have tried the following:
moving the Hub 3 to several locations around the house
reinstalling snow leopard
using a wireless dongle
I live in the middle of nowhere so there are no other houses around which have a hub3 sp none can be affecting me and I've checked this by using programs like inSIDDer.
Finally I thought I'd take it to work to see if I could get the model number of the wireless card and order a new one and guess what it works fine!! So I thought I'd check at a friends and again it works fine for the whole time I'm there.
Brought it home and it won't stay connected GRRRAAA!!!!!!!
I've heard that the hub3 doesn't like having a wireless N & and wireless G laptops on the connecting at the same time is this correct? Has anyone else heard of this?
finnally I do have windows machines in the house and none of them (2 laptops and a desktop which is wired) are having an issue but the Sony TV which is wired directly in to the hub will also drop connection randomly between 8 PM and 10 PM every day so I'm leaning towards the hub being a rubbish router instead of the problem lying with my Macbook

ATV keeps dropping wireless connection, loses connection information...

Hello.
I'm running the latest OS for ATV. Every other day I'm noticing, when I flip over to my ATV, that's it's lost its connection to my wireless network. I realize this may be the result of interference, but when the ATV drops its connection, does it also "forget" network connection information? I mean, I can understand dropping a connection because of interference, but shouldn't it remember the connection information, so when the connection is available again, it just reconnects?
I never had this issue with OS 2.x and only started with the OS 3.x upgrade.
I don't have the option to hardwire the ATV.
Regards,
Kristin.

Since I went to 5ghz wireless N on Apple Extreme device none of my 4 ATVs have lost connection. That was 18 months ago. Before then I too experienced frequent and frustrating loss of signal problems. I picked up a used Apple Extreme on Amazon for about $100 and set it up in the basement, near the center of the house. It communicates well through 2 floors and multiple walls.
