interesting...
what this computer connected to?
a hub, a switch or a router?
and also (as you said that you do static ip addressing)
did you try a higher ip (guessing since your subnet is 192.168.1.0 with your Subnet mask being 255.255.255.0) such as 192.168.1.192 or 252?
also can you try a different interface?
does ubuntu have the same IP info as the windows machine?
it seems that something is missing?
also if the routing device has any logging info can you check that...
