Ok so I have this old wireless router / modem combo. the Westell 327W. What I want to do is run a hard line cat5 from it to my basement and put another router on the other end.

Problem being I have no idea what kind of router to get.
in the basement it would get use from 2 laptops and a desktop that I would want to hard wire with cat5 also to the router because I use it for gaming.

(I have a old Linksys WRT54G with the extended antenna laying around. But I have no idea how to set it up)

I was reading someplace that what I really needed was a bridge, but from what I have seen of bridges they don't have more than one port in the back which is the input from the other router?

Have to bear with me I am terrible at networking stuff too. Never was my forte.
