I want to make a setup like this:

cable modem <-cable-> wireless router 1 <-wireless-> wireless router 2 in another room <-cables-> PCs in another room

Basically, I want to extend my network access across the house and then have a bunch of network jacks available for my office PCs.

Right now, I have a cable modem going to a wireless router in one room and a PC with a wireless PCI card in it in the office on the other side of the house. I use internet connection sharing with the other PCs in the office. The problem is that ICS is flaky, especially when I switch to VPN on the Windows box to access files at work. I picked up a wireless USB adapter that I thought I could share among the PCs I work on but I'm not very happy with it so I'm going to return it (NDISwrapper support for it is poor).

Is this possible? My wireless experience so far has been pretty straightforward so I have no idea what kind of hardware is available. I've looked at network extenders but those just look like repeaters for signal strength. I want wired network jacks in my office.
