Configure Home Router Network

Please see the attached pic to learn more about my situation.

I have two routers at home: Buffalo wifi router and Cisco 1700


So far, i have configured on the cisco router
Fa0/0 with 192.168.12.1 255.255.255.0
eth0/0 with 192.168.11.60 255.255.255.0

route with RIP v2, no auto-summary.


In LAN 1, my PC1 can go online and Ping to LAN2 with no problem.

MY PROBLEM:
In LAN 2, my pc2 and laptop can PING to pc1 and router 1. but they CAN'T go online. It seems LAN2 can't go beyond LAN1 to the internet.


Does anyone if I am missing anything to configure on the cisco router?? Thanks a lot!!!
