Comment 18 for bug 548992

Confirm. Dell D630, Intel 4965AG. Everything was fine on Hardy until I installed Lucid. Don't have problem with unsecured or WPA1-Personal, only have problem with WPA2-Enterprise (PEAP, MSCHAP). I couldn't tell when it get disconnected, but I can use the Internet for about 30 seconds, then it takes about 15 seconds to connect to the servers again, but in the whole time there is no sign that the connection dropped (IP address stays the same the whole time). Same result for both NetworkManager and wicd.

I think this is a problem of iwlagn. I disabled iwlagn (blacklist it from modprobe), installed ndiswrapper and use a Windows XP driver, and it works fine (except ntos-wq keeps crunching CPU).

I'm currently on 2.6.32-22-generic.
