Bug Description
On a fresh 11.10-beta2 install, with the 'Belkin N150 Surf' usb NIC, which uses driver rtl8192cu, network-manager freezes randomly with the message 'Configuring Interface'. It ends up connecting after unplugging/plugging the nic several times in two different ports, even though the connection drops a few minutes later, or displays as connected in network-manager but isn't really connected.
After trying it with wicd, wicd.log shows it may have something to do with wpa_supplicant. It shows WPA_CLI STATUS is ASSOCIATING, and shortly after, WPA_CLI STATUS is SCANNING.
This also happens applying all possible updates (sudo apt-get update + sudo apt-get upgrade).
