Networking/Internet for outbuilding

Specs: Windows XP SP2, Pent 4 2.8 GHz 2.5 RAM
I need to know how to network so I have wireless internet with an outbuilding (shop) that we just built. I ran a cat 6 cable from the house router to the shop and if I plug the shop computer directly into the ethernet jack, the internet works great. If I plug it into a wireless router at the shop I only get local network access, no internet. I tried a crossover cable from the jack to the router but that didn't work. Please help!

Please clarify,

This is my understanding.

Internet --> Router --> Cat6 --> PC (WORKS)
Internet --> Router --> Cat6 --> Router --> PC (NOT WORKING)

If this is the case, log into the outbuilding router's web page, and disable the function called DHCP. (Usually found under the Lan settings).

You should only have one DHCP server per network.

Please post back to advise if this has worked for you.

Your understanding is correct. I can also add:
Internet --> Router --> Cat6 --> Switch --> PC wired (NOT WORKING)

I went into the router and disabled the DHCP server. I still had the same result...PC not connecting to the internet. It doesn't like the router or the switch either.

Thanks for your reply!

You will need to disable DHCP on the second router. Leave the internet router as it is.

Otherwise it will distrubute the wrong DNS address to the clients, meaning that all computers wherever they are on your network will not be able to get internet names resolved.

As Gavin said, leave the router in the house untouched because it's working properly.

Using a crossover cable in the shop from the wall to the router in there is recommended so leave it in place. Ensure you plug that cable into a LAN port on the router in the shop and configure it's TCP/IP info on the LAN side. Make sure the gateway address points at the router in the house.

With the second router setup properly, and with DHCP on it disabled, clients connecting to the shop router should still get their TCP/IP info from the DHCP server on the router in the house. Giving them full network access as well as external (internet) access.
