Always ping the IP address when you get "unknown host." The above
only tells you DNS isn't working. "ping -c 1 81.223.126.153" goes
around DNS.
So, what's in your /etc/resolv.conf?

DNS problem.

"... didn't help" means what? What did dhcp do, what was the result
(messages), etc?

Good to know; I'd have suggested frobbing (power cycling) the router
next. Not necessary.

You have two computers, one of which works fine. How can this be
"urgent"?
