adding a router within a workgroup

OK…here’s the deal. I have an existing workgroup, and added a router to it with a couple of computers behind it. Now, here’s the problem. The computers behind the router cannot access the rest of the workgroup. I have a netgear MR314 router so I can take advantage of wireless networking.

Does anyone know why I can’t see the rest of my workgroup?

Thanks in advance!!

Mike
