Using a used NVG510 wireless gateway.
I recently signed up for ATT Uverse service, and chose self installation. I was aware that they would send me the NVG510 for which I would have to pay $100 for. I figured I would find one cheap at a garage sale and send the orginal back to ATT. Low and behold, I found a used NVG510, but the network name and password has been changed. Any help on how to "reset" the device or work around this would be appreciated. Thanks!
