In my room, I have my cable modem connected to my Linksys WRT54G2. I have an ethernet cable going down all the way to the basement connected right now to my xbox. I want to hook up my older Linksys BEFW11S4 wireless b router down in the basement via this ethernet cable so I can connect wirelessly with laptops downstairs because connecting down with the laptops to the upstairs router is very flakey. An I'll use one of the lan ports from the router in the basement for the xbox. How can I do this? Thanks in advance!
