Hey folks. Trying to learn if anyone else has experienced this. My Casio Commando connected to University secure wifi no problem with Froyo but after the GB update, if I turn on wifi at University, the phone totally freezes, black screen, only a battery pull (out in the parking lot, out of range of wifi so I can turn wifi off again) can restore functionality. It happens if I try to connect to either the secure network, or the one that uses an authentication portal, whereas on 2.2.1 I could connect to both with no problems. An alternative outcome is that I can press the widget button to toggle off wifi and the button itself becomes de-illuminated, but the bar at the bottom of the button forever remains illuminated. A visit to "wifi settings" then freezes the phone as above. Sometimes it prompts to force close "wifi settings" but this is not effective. I got Verizon to mail a replacement, but the new one behaves exactly the same, so it's some sort of software issue I guess with one of the last couple updates with how the wireless network is interacting with the phone. Would love to know if anyone knows where to begin a search for solutions.
