My wife has the same phone. We had the same problem. I ended up configuring my router for a Static IP to address the 8320. That seemed to help things a lot. Now when we are at home, most of the time it's connected to my WiFi.
Try to get the MAC address of your BB and plug in a static IP for it in your router. That should help you out. If I remember correctly I found 2 MAC address in her BB. I can't remember which one was addressed to the WiFi.
But just try them both. Turn wifi off on you BB - set the static IP with the MAC then turn WiFi on and try to connect (sit right next to the router when you do this). Check the IP Address and see if it's the one you assigned. If not, trun WiFi off then plug in the other MAC and turn wifi back on.
If I can help you further just let me know. I think you will have better luck with a static IP.
