this is how i fixed my A-E connection to nokia n800 --- mine also reboots router when downloading youtube or talking on skype or it just wouldnt connect to router so i went to apple and let my nokia connect there to A-e and i was amazed there was no trouble (darn) so i chatted with a genious and he told me to hard reset the airport extreme n and im connecting now and not resetting router and i tried shutting down and resatrting n800 not less than 20 times and still working like a jem 2 hours into surfing and its a wonderful thing if i run into more with this i will post but for now im this was too easy .
