I opened up Network tools, ping, 82.239.101.0  no reply.  Not being
sure which of the addresses to use, I tried them all, the others did
not work either .  I am connected to the router by cable.

I can ping ubuntu.com, and 212.27.40.241, I can not ping google.com

as you can see I am using Network Manager.
