Extending wireless with a 2nd, spare router

I set the IP address of my 2nd router as 192.168.1.x with "X" being outside the first or present router's address range. I turned off the DHCP on the spare router and plugged my wireless cable FROM the original router into the LAN port (not the uplink port) of the spare. This gave me additional wireless range, as the spare router was placed nearer the back of the house. I get a full signal in the garage behind the house, from the spare router. -tp.
