Wireless to Wired routing help

Hi,

I'm trying to network a Buffalo WZR-G240 MiMo Airstation Router
with a NetworkEverywhere NR041 Linksys Router. The Link is the gateway
router with 1 PC and the MiMo attatched. From the MiMo is 1 wireless
Notebook and 1 hardwired PC. The 2 computers on the MiMo are
communicating and sharing, and I am able to access both routers via
Firefox. The PC off the Link is not communicating, and there is no
internet connected to the network when there is a Cable connection with
RoadRunner. I've read a few things and it's still just a little
advanced for my knowledge. If someone could provide some info, and
elaborate on destination IP and routing if applicable, I would
appreciate the help.
