Help with two router networking

Alright, this is the current setup I have between two houses. I have one broadband internet connection in the main house, with a linksys wire router plugged into it. Into the linksys's LANs, I have that house's computer, along with a standard(non-crossover) cable that is running from the WAN port on my wireless netgear router in the second house. This router is wireless, and has both the second house's computer, and an xbox wirelessly linked to it. The internet works fine on all machines, though they can't establish a common network, so computers from one house can't access the computers in the other. I'm wondering what configuration I would need to get these two routers to connect with each other so I can share files and such between houses. The netgear has auto mxd, and I've tried connencting LAN to LAN with RIP enabled, but all I manage to do is lose the internet connection in the second house. Can some help me please?

Well, I've tried connecting the wireless router through LAN, so both routers have LAN to LAN between them, but even with RIP enabled, they don't sence each other on the network. I'm using a standard cable, but my Netgear wireless router has auto mdx, so I shouldn't need to make it a crossover. At least I don't think.

That solved everything and now my network is working perfectly. Thanks a bunch guys.
