Perhaps something to do with the rates the peer supports; it would help if you could grab a scan next time you are in the area. Turn off auto-connect to open networks, then do: # iw dev wlan0 scan trigger # iw dev wlan0 scan dump >> dump.out # do this a few times Then if a particular peer triggers the problem, we can look at the advertised rates to see if anything jumps out. -- Bob Copeland %% www.bobcopeland.com
