I put in an ip address for the computer (192.168.1.6), the Netmask 
(255.255.255.0), the gateway (192.168.1.1)
and the Primary DNS supplied by my ISP (212.135.1.36)

Looking at the desktop:
Mouse arrow on the small "connection" icon at top RHS of screen shows 
"Wired network connection Auto eth0 active"
Clicking the Firefox icon brings up the Welcome to Ubunto 9.10 screen. 
Clicking on any of the links has no effect.
Trying google  (top RHS)  with some word  has no effect.
Putting a known URL in the Firefox address has no effect.

Your help much appreciated.
