2 routers?

i got 2 routers, i need one downstairs in ma house, only prob is that when i plug it in, it says it aint got enough mtu or whateva (found this out through the 360) anyways was wonderin, how would u go about puttin 2 routers in the same house?

if this aint makin sense, jus repost, and i can try and explain further

I would look at the documentation on your 2nd router about setting up 2 routers. The biggest problem is DHCP. That means you buy the internet and an IP address. Your first router gets the ip and using DHCP it gives all other computers in the house fake ip's or private. so when one computer wants to send somthing to the internet it sends its stuff to the router with its private IP. The router sends the request to the internet using its real IP. The outside world only sees you as that one router. When the information comes back to the router it uses the private IP your computer has and sends it to you using that IP.

in short turn of dhcp on your 2nd router
