yeah, pretty hard to go wrong with that, assuming your router routes to 
the subnet in question.

You might try pinging the machine in question from a machine on the 
unreachable subnet. Other than that, I don't know. I guess you could run 
'arp' to see if there are any machines on that subnet in the cache, and 
check /var/log/messages for anything interesting.

One more thing, have you tried replacing the ethernet cable or using a 
different port on the hub?
