I have COX cable. Had a wireless Linksys (WRTG54GX2) set up with my Linksys Cable modem. All is well. Room mate unhooks from Linksys router, and connects his laptop to the modem. He surfs for a while. Now I can't get my LInksys to work. It sees public IP from the modem, but I can't surf or PING the DNS servers.
Do I need to clone the MAC of the laptop? I can get a public IP and surf on the laptop.
