The RNETLINK error is just telling you eth0 is configured with an IP
address.  But having an IP address won't get you to the Internet if
you don't have a default gateway.

any of the following should show you your gateway address:
netstat -rn
route -n
ip route show (or: ip ro sh)

You are looking for a line that starts 0.0.0.0 or default via ...

Without that, you're going nowhere.

ip ro add default 192.168.0.1 via eth0
(substituting your default gw for 192.168.0.1 should do it for you)
or:
route add default gw 192.168.0.1

If you still have problems, check /etc/resolv.conf and make sure you
have good nameserver lines.
