    Hello –

    I am trying to connect my router to my Comcast modem but I cannot seem to get an IP address. I recently wiped my config and just have it setup as basic as possible to get an address. I will configure the NATing and everything else later. My linksys gets an IP no problem, but not my 2611. Help!

    I am also getting DHCP discover requests being sent out from the router on the e0/0 interface but not getting any responses.

    Am I doing something wrong?
