Whenever the software asks for an AP scan, the device disconnects from its current AP and blacklists it, making it impossible to reconnect until I kill wpa_supplicant. If I manually configure wpa_supplicant and launch it directly, the adapter stays associated with the AP properly. I was able to reproduct this behavior with kernel version 3.0.4, 3.1.4, and 3.1.5, but downgrading to 2.6.39 or lower solves the problem. I haven't seen any other reports of this problem specific to 3.x -- did I miss some other step I need to do when upgrading?
