I too have this problem. I don't think its specific to wep though as I have WPA and the same issues.
always dmesg says: wlan0: disassociating by local choice (reason=3) and manual wpa_supplicant just spins trying to connect and getting booted. ** Changed in: network-manager (Ubuntu) Status: New => Confirmed ** Summary changed: - Cannot connect to WEP 802.1x network + Cannot connect to wireless networks.
