I played with this thing little bit more tonight at hotel. What I can say that with my N800 the WiFi and Bluetooth are absolutely NO-NO to use at the same time.

I'm starting to wonder if my N800 is somehow defective? Anyone has similar symptoms that with Bluetooth on (such as MaemoMapper running and searching GPS receiver, actual GPS receiver was not powered on) your WiFi connection gets very erratic?

The hotel AP seem to be on channel 6... so this does not seem to be related to channel 11 as I previously though.
