Sure enough (netstat -rn):
-----------------------------------------------------------------------------------------------------
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
24.93.45.0 0.0.0.0 255.255.255.0 U 0 0 0
eth0

I'm using a cablemodem (so dhcp obviously). I have bee trying to just
ping the
IP addresses that are listed in resolv.conf, since I know those are the
closest, and on my
network, but that's that's where I get the "network unreachable".

That's what I figured, but I can't figure out why I don't have a default
gw
anymore. I did before I upgraded everything and now... not so much.
How can I manually
set the default gw when I'm using dhcp?

I used netcfg originally to setup my network, and it looks the same now
as it
did before, the settings within I mean. Should I try to removing my
ethernet
adaptor and then adding it again in netcfg to 'fix' the net scripts?
Thanks for the
recommendation, I may pick it up if I can squeeze it into my budget :)
