First: is the green led around the network port on? If yes, hardware link is ok.

Second: "ip link" should list all interfaces on the machine, including eth0 or
similar wired interfaces.

Third, "type dhclient" should list a binary. If that program is installed, we
can try bringing up the network with DHCP manually. As root/sudo:

  service network-manager stop # getting rid of evil, fails if not installed but that's ok
  dhclient -r ; # release stale dhclient instances brought up by scripts in /etc/network
  pkill -SIGKILL dhclient ; # make sure all dhclients are dead
  dhclient $your_wired_interface # eth0, often. Try to get a new DHCP lease

route -n as suggested by Stephen should now return the routes common on your
network. If you get errors about interfaces being down, do "ifconfig $interface
up" before doing the above command sequence again. If not, inspect the output of

  grep dhclient /var/log/syslog

since dhclient is logging quite verbosely to the syslog. Any errors logged here
should provide pointers to the underlying/actual network problem.

Best regards
Jens.
