Wireless event: cmd=0x8b15 len=20
Wireless event: new AP: 00:0d:ed:c3:02:1b
State: 4WAY_HANDSHAKE -> ASSOCIATED
ioctl[SIOCGIWAP]: Invalid argument
Associated with 00:00:00:00:00:00

These are driver problems.  First, the driver says it's associated.  The
SIOCGIWAP event should _not_ fail here, it should be returning
00:00:00:00:00:00 if disconnected, or a valid BSSID if connected.  It
shouldn't be returning EINVAL if it's connected.  If it's _not_
connected, then it should have sent a disconnect event right when it
disconnected, which it doesn't appear to be doing.
