DHCP and @home HELP!

[star_rob]

Hi guys,

Setting up my first home network and am getting a bit frustrated. I have purchased a Linksys BEFW11S4 EtherFast Wireless AP + Cable/DSL Router w/ 4-Port Switch. Trying to get it to function with a COM21 Cable Modem and comcast@home network with Win98. Without the router in place, everything is great. Set up with hostname CCxxxx-A hostname @home workgroup and DHCP enabled.

With the router in place, I cannot get an IP from DHCP anymore. Everything I have tried ends in failure. I enter Hostname "CCxxxx-A" and domain "@home" with DHCP for lan enabled as per instructions and I get no IP address. (Rebooted and did the renew thing for DHCP) The enternal LAN DHCP seems fine...I can see the router and get to the router web server. I have also tried it with the domain as home.com and my fully qualified name witch is something like albqrq1.home.com. I got this info from the @home support section. No luck. I still cannot get an IP address established for the router. I tried winipcfg and input all the info directly rather then using DHCP and I it then works. The problem with this is 1. @home says not to do this and 2. After a while, it stops working unless I reset the Router....I assume because my IP lease expires. Anyone with Ideas? Anyone successfully getting DHCP to work with a Linksys Router and comcast@home? I have no clue what else to try.

Thanks for your time,
Robert

Just a thought here. Have you configured the PPPoE on the router. @Home may be using PPPoE for validation before you get assigned an IP.

Try "cloning" the mac address from your nic card in the router setup. Some ISP's use MAC address for authentication. Check out your manual for how to do it.

why?..

@home doesnt provision the nic card, that is rr.

It was just a guess, I wasn't sure if all @Home was the same. Can't think of why else the router can't grab an ip address.

double check the DNS numbers, cant tell how many times i have seen them entered in wrong.;)

Thanks for the help guys!. Ok, last night I played around some more and still, no luck with DHCP. I can't get an IP to show up through the router. No problem if I take the router out of the picture though. I just go to the TCPIP on the nic and put in my CCXXXX-A and @home for workgroup and everthing is groovy. I am able to connect when I plug in the IP gateway and DNS stuff through the router manually. Something weird with their DHCP servers? I have tried MAC cloning and still no dice. Someone mentioned making sure I have the correct DNS numbers. Maybe this is where I am mistaken? I thought you didn't need the DNS if you were using DHCP. I don't need it without the Router in place. If I should enter the DNS info when using DHCP through the router...where do I put it? On the Nic side or the router side? Do I need to fill in the host and domain if I enable DNS?

The only reason I don't like the static IP is because it seems every so often I am forced to reset the router. My guess would be my lease expires on my IP and is not renewed automatically if I don't have DHCP enabled.


Thanks!
Robert
