When it is connected directly to the router, what IP are you using 
then?  Can you post your
ifconfig -a
output then, and when it is connected to the router.

What router are you using?  How do you have it set-up?  What are the IP 
settings for the router?  What are the DHCP settings?  Can the router ping 
itself or other hosts?
