If you are unable to connect to any website it could be: 1) If you used network manager to set the manual (static) network address, try logout and login to make sure all your apps picked up the network change. 2) You have not entered the right IP address for the gateway and / or Primary DNS - Check the settings on your windows machine - you will probably find the gateway and dns is the same IP address, possibly ending in 254 or 0 or 1. 3) A proxy setting on the firewall - check the LAN settings on your windows box If you can surf the web but cant do apt-get updates, etc, something could be blocked on the router :-( Good luck. -- John Stevenson Lean Agile Consultant / Coach jr0cket.com | leanagilemachine.com
