Since the Icecream Sandwich update for my HTC Thunderbolt, my phone connects and then disconnects with my wireless connection in my house or anywhere else. I have a strong signal, but then it drops. I have to turn WiFi off and then on again, and it will stay connected for a little while and then I no longer have a WiFi connection even though I am right next to my router. This didn't start until the update. I have seen in the forum that other people are having the same problem. What can we do to fix it? Thanks.
