When a nullfunc probe fails for lack of an ACK, it is retried almost immediately. The current setting of 2 retries completes in about 4 ms. If an AP is off-channel scanning, this is not enough time for the AP to return to the operating channel and ACK the nullfunc. As a result, the client disconnects when the AP is still there and operating.
