Hi, I was wondering if it would be possible for me to use two WRT54G routers in line in a certain set up.

The first WRT54G is currently on the first floor connected to the cable modem and this what is now used for my home wireless network... and with this I would like it to remain operating in that capacity.

I have a second WRT54G that I would like to put on the second floor (hardwired to the first one with a single 100' ethernet cable) to be used as a "switch" that I could hardwire two gaming PC's to. I don't really have any concerns about the second unit providing any sort of wireless network support. as the first unit can reach every device in my home with full signal.

I was told that this is entirely possible to do. But I just have no idea how to go about setting it up. Is it as easy as just wiring it all together and powering up? Or will the second router require some modification to make it operate correctly?

I sketched up a (crude) diagram to show what I'm looking for
