I've been having a problem with my BB on my wifi network. When I put the wifi on my BB on it logs in and I get the BB logo next to the wifi icon, but after a while the BB logo goes away while the wifi is still logged on. I guess that means BB is not connected to the NOC through wifi. I then need to shut off wifi on my BB and restart. Does anyone have any clue what's going on? I have tried automatic settings and manual settings for my wifi network.
Also having problems with BBM7. I can only talk for 45 seconds before the call drops off. Any solutions?

Does your phone lose the BIS sync (four dots) when you're off WiFi? If so, it might be a network or service books issue.

Regardless, I'd try a manual resending of service books, and re-registering using the Host Routing Table.

For BBM7, I read in a couple of threads that uninstalling and then re-installing it has worked for some people. Why don't you give that a shot?
