You may be able to just add a router. And Linux is not a problem...
I am setting up a home network (or trying to) but my situation is slightly complicated; I have two computers at my home which I want to share a broadband connection (supplied by Pipex Homecall). However one of the computer is a dual boot with Ubuntu and I would like to have an internet connection using both Ubuntu and using WindowsXP.
My plan is to use an ADSL router( i have my eye on a DSL-524T ) and connect everything to that. I assume that both Windows XP and Ubuntu will work with this router? I'm not entirely sure how the ISP fits into all this though? They provided me with a modem and an installation disk when I had just one computer. I have already contacted them and they don't know anything about linux, so they helpfully suggested I search on the internet!
sorry to babble on. any help appreciated. I am sure that for many budding linux users this is a common problem.
