Both, quite radical for me.  The laptop was already "re-built" 
with the built-in restore, so the problem can't be the PC.

Also.. the PC had no problems connecting to my own network that 
apparently uses the same 192.168.1.1 starting point.  Internet 
was smooth, and no ill effects to my network of PCs.

The user was not given any login credentials to the router.  I 
was thinking of just doing a big fat button reset, but I was 
afraid that might wipe out some particulars the provider 
programmed it with.

Anyway.. all seems to be good since I simply forced the PC to use 
a specific IP address and the gateway address.

Now, I seem to have other problems of my own: my regular laptop 
is simply not starting up. No AC/power light at the laptop even 
when the AC adaptor is plugged in.  :(
