The first entry is your local network, and says 'anything for 192.168.0.1 
through 192.168.0.255 send locally'.  The second entry says 'anything else, 
send to 192.168.0.1 and it'll handle it'.  So the question is: is 192.168.0.1 
your router or your own machine?

Then there's the question of how your name resolution is set up.  What's in 
/etc/resolv.conf?

To take a step back here, does the router support DHCP?  If so, try doing 
'dhclient eth0' on your Linux machine.  That will not only set your routing 
correctly, but will also set up /etc/resolv.conf correctly and do bits of 
other plumbing to make your Linux machine talk correctly to the internet. 
It's much easier doing that if you're learning your way around than to try to 
do all of what dhclient does manually.

Hope this helps,
