i actually have a lynksys broadband router for my system
what i did was setup up my ether net card for dhcpd
and then i set up the router via a webrowser you connect to its default ip 192.168.1.1 and set it up
if you are using dsl just enter some simple things click on PPPoE and connect its pretty simple i really didnt have
any problems at all

good luck

if you have any problems just contact me and i will be happy to lend a helping hand
