Internet connection sharing problems

I just installed Fedora Core 2, and tried to get it connected to the internet, with no luck.
on my home network there are 3 computer (one is mine), with windows XP on them (including mine).
all 3 computers are connected to an EdiMax router, and he is connected to an eci (B-fucus router 270pr) modem.

I'm begining to think that the router just doesn't support a Linux computer, because I've tried any possible configuration (I think :? )..

let me know if I need some software to identify me in front of the router, or something else...

I need help..
