I'll just get straight to it. I have a WRT54G v5 that I have running to my Cable modem. I would like to use an extra (linksys)BEFW11S4 v4 I have laying around to extend the range of my network using about 80 feet of ethernet that is running from one end of my house to the other. Except I don't knowwhere to start, or if it's possible to use a wireless router as a wireless switch. It doesn't particularly matter to me in what order things are connected, just so long as I have a wireless access point at each end of the house that both have internet access and are on the same network. Is what I ask possible?
