Configure wireless by hand

[Gordon Charrick]

I've got a little netbook and I've put a copy of Fedora 10 on a USB 
stick. If I boot up using runlevel 5, I can use the wireless via 
NetworkManager. These netbooks don't have the speediest processors so 
I'd like to use runlevel 3 most of the time. I haven't been able to get 
the wireless to work that way. How can I configure wireless by hand?
