i got a problem with AWUS036H with r8187l chip. It disconnects the wifi connection after 10 mins+-. i tryed it with a clean BT5R1 and it didnt help. its working fine with ubuntu 10.04.
i tryed other drivers, nw manager, wicd, static ip and so on... couldnt resolf the problem :/
bt kernel: [ 1163.079035] wlan0: deauthenticated from 5c:d9:98:e1:da:26 (Reason: 3)
this is what syslog says at the connection drop
