I have a Linksys WRT54G2 Wireless Router. Every so often it decides to stop transmitting. I have to reset the router everytime and its doing my head in! Sometimes it will go a week before I have a problem and then other times it will do it upto 3 times a day.

It has the latest firmware installed. All encryption etc is set up right. No other electrical items are nearby. I have no cordless phones to interfere. I've tried different channels. The router sits only 6ft away from me so it's not a distance problem.

I had the same problem with a Netgear router I used to have. Exactly the same problem.

When my WAG54G started doing that, it had a bad electrolytic capacitor on one of the PCB supply lines. I replaced all the electrolytics on the circuit board anyway as a precaution.

Off the top of my head I don't think the WRT54G is as prone to this, but almost all routers/modems can have capacitor problems. It could be the cause of your troubles. Likewise bad capacitors in the PSU unit can cause misbehavior, which can be checked for by getting to use a known good PSU for a while.

If this has happened with two different routers I don't think the router is the problem it may be the wireless adapter on the computer. What kind of computer are you using?

if you connect directly to the modem do you get the disconnects
if you connect with a cable to the router do you get the disconnects
do you have more than one PC connected do they also disconnect

when its working post the following test results - then also when it disconnects post ALL the results again

If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

We would like to see the results from ipconfig /all post back the results in a reply here

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste

Run Xirrus Wi-Fi Inspector Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

http://www.xirrus.com/library/wifitools.php
Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, http://www.bleepingcomputer.com/forums/topic14738.html

Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

If you are using the Mac OS then use http://www.istumbler.net/
