    I recently got a WRT54GX and have been having problems during periods of high network activity for WIRELESS ONLY. This is what I have done to test this problem, it should be noted that I am using the same file just for kicks, however it doesn't actually matter as any sustained transfer will cause the problem.

    Connect with my laptop via wireless to my router, download largeish file, within a few seconds I will get disconnected. My roommate, on a wired connection to the same router, will NOT get disconnected.

    If I connect, using my laptop, to my helpful neighbors unsecuried AP and download the same file, there are no problems.

    If I connect, using my laptop, to my router with a WIRE and download the same file, there are no problems.

    My firmware is the latest Linksys firmware for the WRT54GX, I got a clean copy of the firmware and flashed it just to be sure, no change. In all cases my signal strength and quality are at, or near 100% (I did tests sitting right next to the router just to be double-sure).

    What other kind of tests can I perform to get more useful information, or does anyone have any thoughts on the problem?

    Any idea what hardware the neighbor is running?

    No idea, but it doesn't really matter, I don't think. I have used this laptop on many an occasion at coffee shops, friends houses etc. One test I have not done is to have a friend of mine with a different notebook come over and try it...I will try that next, but I think it's probably RMA time.

    yha, if I'm doing full 54Mbps client to client copy via this router it crashes... even with Firmware Version: 1.01.07 ..

    It doesn't do it right away... sometimes I can copy as much as 3GB ... but it seems like it overheats or something.

    I'm in relatively cold temps too, as low as 65 degrees F inside...

    Try setting ACK Mode to "Immediate". This same issue was seen sometimes in the Belkin F5D8230-4 (essentially the same router - same mobo and firmware from Airgo with just cosmetic changes), and is almost universally solved with Immediate ACK.
