That depends on whether you are using fixed addressing, or the router has a 
dhcp server in it.  I do both here, with an /etc/resolv.conf set as read 
only, and pointing at my dd-wrt router, with a dhcp server enabled on the 
router, basically for the lappy.  All other machines here use host files and 
fixed addressing.  No dhcp listed in the ifcfg-portname files at all except 
the lappy.

So check the server settings in the router, and its NAT settings too if the 
above doesn't tickle a memory.
