|Yes it's possible. For information on how to connect the second router click on my name above in this response and read my “how-to” guide titled, “Add a second Router to your LAN”|
You'll want to use the scenario where you interconnect the two routers using the "LAN port to LAN port" configuration. You will want to disable DHCP on the wireless router because the DHCP on the router connected to the internet should already have DHCP configured and enabled.
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.
