Network Problem

[Pete Holsberg]

I turned all my computer gear off when the wife and I went on a short 
vacation and now I'm having a strange network problem with the ubuntu box.

The other PCs are up and running as is the DSL device -- all Internet 
connects are fine.

On the ubuntu machine, I can log in to the DSL router (via wireless 
connection) and see that the router's Internet connection is up and 
running, but I cannot make a connection of any kind beyond it, even if I 
supply the IP address! I can ping the two PCs.

What could be wrong?

Thanks.
