Hi list, I have setup a mobile pc to roam across our building. By reducing the dwell time and changing the channel list to only the channels I use roaming now works within ten seconds en sometimes within one or two seconds. The previous configuration was with fedora and there I was unable to get roaming time under 25 seconds. I do have one very annoying problem however and I have no idea how to solve it. The software uses psycopg (a python postgresql module) wich uses the standard system parameters for connections (At least that is what I think). -On fedora if the connection gets lost and it takes 30 seconds to remake a new connection operation is not interupted, after the 30 seconds you get the data you've been waiting for. -On freebsd however we get it a lot that the connection is "lost", you can easily start a new connection wich works fine, but the old connection you wore using stops working and the app. hangs (If I had to guess I would say that roaming works about 95% of the time and the connection is lost about 5% of the time). I also get a lot of IFDOWN IFUP messages but this seems normal to me. Is there some way to tune sysctl values so that it doesn't lose the connection or how should I proceed in debugging this problem ? Sorry about my poor english Tkanks in advance
