Wireless

I am trying to set up my wireless using Fedora 6.  So far unable to get 
it to work.

I am presently on a completely wireless setup.  No ca ble or DSL modem.  
I just connect to a wireless network.  Do I need another driver, or am I 
just missing something.

The card comes up and will show a very low signal, but X's on everything 
else.  Trying to figure out were to start.  I am brand new at this stuff.

Thanks
