Another member told more such as their 64 character password. You didn't tell much. And we know the WEP will do this. Fix? Don't use WEP.
I am running Windows XP Professional Version 2002 Service Pack 3 on a Lenovo T420. My wireless network connection works fine everywhere (airport, hotel, coffee shop, etc.) except on my home network. At home, it will connect and then disconnect seemingly at random. Once connected, it will stay connected for a while (60-90 minutes) and then disconnect. Later on, it will reconnect again. I don't have this problem with any other devices that I use on my home network (Windows 7 desktop and laptops, ipad, printer, etc.) Any thoughts on how to diagnose / troubleshoot would be appreciated.
