One of the routers should be set to IP address 192.168.1.1 and the other should be set to 192.168.1.2 otherwise neither will be able to communicate on the network. Connect a computer directly to port 1 on tyhe second router and adjust the IP address accordingly. Then Disable DHCP on the router, you want the primary assigning the address (this will prevent IP address conflicts). Are you using a crossover cable configuration, if not do so. Go from one port on one to another port on the other (DO NOT USE THE WAN PORT).
