Can't remember ever seeing 127.0.0.1 in a "route -n". Maybe you're
thinking of "route -nC" Nick.
Anyway, the absence of 127.0.0.0 is not important here.

Not *clearly* wrong since the Linksys maybe issuing another one of its
private IP interfaces as the DNS server address. But yes, 192.168.1.1 is
likely to be a better bet. The PC can get to it because it's only got one
default route - via 192.168.1.1 as it happens!

If that doesn't work, try changing /etc/network/interfaces as such:
--- Snip here
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
mapping hotplug
script grep
map eth0
iface dsl-provider inet ppp
provider dsl-provider
iface ppp0 inet ppp
provider ppp0
--- Cut here
Then do "ifdown eth0" and then "ifup eth0".
Then do:
host www.google.co.nz
arp -a
ifconfig eth0
route
By the way, do you have a link light on your network card and on your
Linksys?
