My icon shows that the connection is good using wifi. However, I could not go online. What's wrong ?
Thank you !

Several things might be causing problem. First, verify that you can ping the router. Check (post) results of route -n and contents of /etc/resolv.conf. Help is available for these tasks if you need it...

You've probably already noticed that you have no gateway or nameservers. Ordinarily, that information is provided to DHCP clients by the (DHCP) server - if you're set up for DHCP.
Are you using Network Manager, and is it set up for DHCP?

I am sorry ! I am a newbie. I am not sure if I am using network manager or not. What can I do then ?

Unless you specifically set up a static address, you probably use Network Manager and DHCP. Why your DHCP server (router) doesn't "play nice" is a different question... I'll need to fire up my Jaunty laptop to see how it handles wireless configuration.
