wireless networking in ubuntu 8.04

[Harold Hartley]

I am running ubuntu 8.04 on a Dell Latitude D800 under Gnome.
I have my wireless working just fine, but I have to redo my settings 
everytime I boot up.
I'd like to know if there is something I can do so I don't have to redo 
the setting for my wireless each time I boot.

I'd like to know what network tools are out there under gnome that will 
display all the wireless networks within my network.
