I just got my N900 and it's a great device for the most part, but it seems to absolutely not get along with my WPA-protected home network. Actually, it worked fine at first and continued to do so for a few hours after I initially turned it on, but then the problems started. Basically the connection will stop working and then I will get an 'Authentication failed' message and it will ask me to enter my WPA pre-shared key again. This is despite the fact that the key I initially entered was working for a while and I certainly didn't change anything. After getting this message the first time, no matter how many times I enter the key again it will never work. If I reboot the device a couple times, reboot the router, and pray I might be able to get the connection working again...for a couple of minutes. Inevitably I will start having the same problem again soon enough. Despite what the device is telling me I am not at all convinced that this is an authentication issue. In fact, if I look at my router's log I see a bunch of messages saying 'Authentication success' with the N900's MAC address. I think the actual problem it's having is that it's not getting an IP address for some reason. However, I have had absolutely no problem connecting to other networks. Actually, I've resorted to stealing the neighbor's wifi since it doesn't want to talk to my router...but that is not a solution. I do not want to disable the WPA encryption on my network just to get my N900 to work and I shouldn't have to. Any suggestions?
