DNS problem with Linksys router

I have debian linux on my laptop and connect to the outside world using a
linksys adsl2mue modem and wrt54gs router.
I'm having some problem with connections: due mainly to gross ignorance,
and any help anyone can give would be much appreciated.

Everything works when the laptop is
running windows xp, but I don't usually want to do that.

Running linux I can ping succesfully but many other programs, ssh, scp,
mozilla, netscape, will not work
unless I find a specific ip number (using ping) and then
use that instead of a domain name. I've tried editing
resolv.conf, but so far to no effect.

ifconfig returns the following:
