Recently got Comcast high speed internet. They gave me an Arris Telephony Touchstone modem # TM502G. I don't have any problem with the wireless aspects of the WRT54G, however I cannot get the router to make an internet connection with the modem. I have cloned the MAC address and I have changed the local IP address to 192.168.2.1. None of these actions have caused the modem and router to communicate. I would appreciate any help to quickly rectify this problem.
