Oh. I didn't even think about this part, but that's just a consequence of having a hidden SSID. We need one entry to track the beacon, and then we add another entry for each hidden SSID it may have. Some APs implement multiple SSIDs that way (old Cisco equipment, IIRC, though then with zero-length SSID instead of zero-bytes), so you can't lump them together into a single BSS entry. > It would seem that even with the flush flag set, there could still be > spurious beacons getting in causing these results to appear in the scan > result set, right? In general anything can, there's no filtering. So you might do a flush scan for a specific SSID and still get 20 (different) results, if 20 beacons happened to be received while you were scanning. johannes
