Hi again Colin,
As you suggested above I started the PC & ran ifconfig:
chas at Charles-PC:~$ sudo ifconfig -a
[sudo] password for chas:

Before I could paste the results above, a message showed "Disconnected"
and soon "Connected" again.
Restarted the PC & ran ifconfig:
chas at Charles-PC:~$ sudo ifconfig -a
[sudo] password for chas:

Hooray. Opera works on my ISP websites so the router is "Connected"
So what do you suggest now?
Sorry for the long email with all the ifconfig results.
I wonder if I could disable the network card (eth0) in bios before
Ubuntu boots up?
