Bluetooth uses the same frequency as wifi. Try changing the channel on your router. If you cannot do so then you SOL. I had the same issue at work, but when I came home it worked fine. Difference was that at my work place there were several Access Points that had channels probably overlaping with the bluetooth.

So try changing the channels. I recommend channel 11 on the router. In the shell I had a ping running to google.com. When I hit a channel that gave me the lowest ping and the least packet loss, I left it at those settings.

To verify that the problem was resolved, I simply played an mp3 on the N900 that was streaming to my headset and then I started websurfing, youtube and so on. All the while that my skype was connected as well.

I have the N900 with PR 1.3. I actually put the power kernel on it. My N900 is overclocked at 850. Everything is super snappy... !

Love this phone... am really looking forward to Nokia's Microsoft venture. Hoepfully it will bring out something new.
