|Click on my name above in my response and read my how-to guide pertaining to 'adding a second router' to your LAN. You'll want to use the version wherein you interconnect the two routers "LAN port to LAN' port.|
You'll want DHCP off on the downstream router once it's configured to be part of the same LAN as the one connected to the internet. Since you have them hardwired (much better idea than connecting them wirelessly) you won't need to put one in "bridge or repeater" mode.
You will want to configure the exact same wireless settings on the second router as you have on the first with regard to SSID and encryption key. You will want it on a different wireless channel (ie: if router 1 is on channel 11, put the second router on channel 1)
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
