OK, your interface is UP and RUNNING. Though M$ can reach the gateway,
can your ubuntu ping 192.168.0.1? If so, what about the IP of the
gateway's other port? If so, any of your ISP's servers?

Packets are coming and going, so it may be a route issue, as you appear
to suspect. A quick alternative to pinging is to try "traceroute
202.113.16.10", if you have it or quickly install it. 

Has the machine been up a long time, with a "route add ..." done from
the command line? That wouldn't hold across reboots, obviously.

As a last resort, what's in /etc/network/interfaces?
