My Droid Charge connects to a WiFi signal without any problems but after a few minutes it will stop sending and receiving data over WiFi. It shows a strong signal in settings and that it is connected still. I run speedtest app and it can't find a server. If I disconnect WiFi and reconnect it will work for a few minutes and then the same thing will happen again. I have tried several different locations with the same results. Thanks in advance for any help!
