Just set up my new phone yesterday, at first, the wi-fi was fine, but after a few hours the happy green color of the wi-fi icon started going white. Now it always seems to be having trouble, it doesn't seem to "like" my wi-fi. It is constantly "obtaining IP address" even though it worked in the beginning. Would the "wi-fi protected setup" help? I don't know what it means and the "Quick start guide" that came with the phone is seriously lacking in detailed information.
