Workgroup broken with added routers
I've got a network of about 70 PC's here, all on the same workgroup. We added a couple of wireless routers to add wireless access around the building. In one room, we were short on connections, so we plugged the router into the connection, and then plugged the three PCs in there into the wired connections on the back of the router.
All computers on the network still have the same workgroup name, but now the two are separated from each other; the three computers down here have their own workgroup, and everyone else not on this router has their own, and they can't see each other.
Is there any way to fix this with what we have? Should we have gotten "wireless access points" instead?
