I am trying to set-up a Cisco 2901 router that is connected to a Comcast High-Speed Modem.  The connection is live since I connected a laptop directly to the modem and the internet works.

Below is the configuration from the router:
no service pad
service tcp-keepalives-in
service tcp-keepalives-out
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
service password-encryption
service sequence-numbers
!
hostname Cisco2901

boot-start-marker
boot-end-marker

no aaa new-model

no ipv6 cef
no ip source-route

no ip bootp server

 no activation-character
 no exec

Is there something I am missing?  It tries to connect from the laptop, but just keeps looping.
