wifi card disconnected right after assoicated with AP

[Shu, Nick]

Hi, All:
I'm trying to use a wifi card to associate to a access point, but got a strange thing here.
Right after associated with AP, it disconnected from AP, the pattern repeated for:
Scan
Authentication
Association
De-authenticated
Dis-associated
I captured the frames as below, saw a "wlan0 del station <AP's MAC>", why wlan0 do this local request?
