I have used xbox live for a couple years while we had ATT, don't remember the type of router...have recently switched to comcast due to a move. We are now hooked up through a NETGEAR WNR1000v2. i have tried everything step by step through the xbox website, but i cannot get connected. Have manually entered IP info, changed to an alternative MAC address, even added 5 port forwardings. I am getting nowhere...HELP!
