My wireless network adapter keeps failing and the console light goes out. Switching it on and off using Fn-F5 does nothing when it has failed. It is re-enabled when I reboot but fails again after a variable time from minutes to days. Windows XP and Lenovo are both fully updated. I'd appreciate any advice.

Thanks for the quick response and helpful advice.
I don't see WLAN listed under Add/Remove Programs. The only relevant entry I see there is Intel PROSET/Wireless Wifi Software. Is this the same thing?
Searching for WLAN shows many directories and files, such as C:\drivers\WLAN. Maybe these are installed by the Intel entry above?

Wlan means wireless local area network, which in your case is the Intel pro card, so that does sound the the correct drivers to uninstall.
I'm inclined to think that you have a thermal hardware failure, since you say it works for a while when first starting the system. If reinstalling the software doesn't fix it, then you may have a bad card, or even a bad system board. That is a common part (intel pro 3945ag), I have a few sitting on my desk, but it's a shame I'm half a world away... but check if you can pick on up local to you, would be the easiest way to tell if yours is bad to just replace it. A used one sells for about $5 here.

Thanks for following up on this. I can't find 3945AG mentioned in the T61 HardwareMaintenanceManual. Any pointers to how to go about replacing this part assuming I can locate it locally?

I am in Zimbabwe but I am meeting someone from New York City in Nairobi in two weeks time. Is there any way we could discuss getting one of those parts off your disk to me that way?

Sure, send me a PM and we can discuss how to get one to you.
