So the clients are connecting and I get 25 mbps data rates. But if more then 10 meters from the antenna strange things are happening. - If I am connected to the network and will walk away everything works perfect. - But if i disconnect (disassociate) when I am away I cannot connect back. - this also means I cannot connect when turning the notebook on :) - if I go closer to antenna I am able to connect and while walking away the connection seems perfectly stable ... My first idea is the congestion control issue ... But maybe some will have the better idea. Regards Tomasz -- Tomek
