Several months ago, I switched from an Apple AirPort 802.11g access point to a Apple TimeCapsule 802.11n access point. Due to the security requirements of 802.11n, I was forced to switch from WEP to WPA. Specifically, the TimeCapsule is in "WPA/WPA2 Personal" mode.

At around the same time, my N800 running (then) OS2007 and now OS2008 has become very unreliable w.r.t. staying connected to the network. I'll boot the device, listen to (say) 10 minutes of internet radio and then it will stop. Canola will say "Network is down" and indeed, no network access will work. However, the home screen will say that it is still connected to the access point, and show fine signal strength. Sometimes, I can disconnect from the network and reconnect, and then things will work again (for awhile). Other times, I'll have to reboot. Other wifi clients (macbooks, powerbooks, roku soundbridge radio, tivo, hp laserjet) work just fine so I don't think it is the access point.

There is never any problem connecting to the access point, only a problem actually making network connections.

It feels to me as if it is a problem with the security mode. I am somewhat unwilling to disable all security for a few days in order to test this theory. If it isn't a software problem with the encryption mode, then perhaps I have a hardware problem with my N800.

I'm posting in order to see if anyone else has problems operating in WPA mode, and especially if you are using an Apple Airport Extreme or TimeCapsule.

Suggestions?

Thanks,
