Can't browse any where - FC1 freshly installed

[Barry Yu]

When tried to go to any website, getting alert "The connection was 
refused when attempting to contact www.google.com"
When I issued "ping www.google.com" I got "Connect: Network is unreadchable"
**
I can pint 192.168.1.1 (The router ) successively.
The firewall is turned off.
This FC1 is a fresh installation.
This machine works on w2k,
This machine also worked on Red Hat 9 before this new FC1 installation.
This machine has fix ip add 192.168.1.222, the router (gateway) is 
192.168.1.1 and I can ping it without failure.
can any one provide some steps to diagnose this ? Tks a lot.
