My Nokia N85 is often failing to reconnect automatically upon wlan availability. E.g. when I leave home, it gets disconnected, but when I arrive at my office (which also has wlan), it often simply fails to reconnect and in the contacts-> Gizmo VoIP tab, it shows "Connection failed" message and won't reconnect, unless I manually ask it to connect (by pressing middle button). I am really feeling frustrated as I dont even know when it would fail (sometime even when walking in my office building, it would just fail, due to a prolonged unavailability of wlan). My firmware is latest version (30.019). I would really appreciate any suggestion.

Thanks
