need help with dynamic routing for Comcast

[Siva]

Comcast switched their network from one with static IP addresses, to one with dynamic IP addresses. I can't seem to get my router to work (linksys BEFSR41) no matter what i do. My settings appear correct, but under status the IP address is always shown as 0.0.0.0 as is the host address. Any ideas as to why?

As far as I know you should have the WAN IP Address configured as "Obtain an IP Address Automatically". That said it doesn't matter if the "Specify an IP Address" portion says "0.0.0.0", because you are no longer using a static or fixed IP. You will probably need to have "PPPoE" and "DHCP" enabled. Make sure the "Number of DHCP Users" is set to at least 1 (the default is 50). Do your idiot lights on your router light up showing you are connected to the WAN? Same goes for your modem, if there are any idiot lights. Have you tried the "Disconnect" button and then a few seconds later the "Connect" button? Sounds lame but sometimes if I lose my connection I'll go into the router setup it will still show me connected, and I'm not. If I do the "Disconnect" and "Connect" thing it usually fires right up. If not I have a hammer you can borrow.

yeah my router is on DHCP. i just had to enable dhcp in the router program, and in my LAN connection on the computer (should be an option like: get IP address automatically).

Actually i didn't need dhcp for my router. I had obtain IP address automatically, but what I had to do was clone my MAC address for my NIC on the main computer to the router, otherwise it wouldn't allow the router access.
