Cable router working - bafflement

The Linksys WRT54GR arrived. I plugged it all in. Then went to the set
up page which has lots of queries about DCHP la la la. I get a few from
System Prefs, but am stumped by the rest and the router web page won't
let me do anything. I am about to give up and ask Here/Virgin MEdia/etc
when I launch Mail for the hell of it, and find emails coming in, and
Safari working fine, and the laptop connected also by ethernet to be
working fine too.

Is a cable connection simpler than ADSL through the phone line??
