Is it possible your wireless channel was overused? Most of my neighbors have comcast, as do we. I've had poor coverage and connection also, couldnt even get our wireless printer to work anymore.

Cleared up all of our problems instantly. I would check this, perhaps his google modem was preset to another channel.
