Hello mudmansm
Don't have that particular card, but I do use wireless under Fedora 8.
I understand you have identified the card from lsusb.
Have you tried the following commands:
The output from the first command should tell you the name assigned to your wireless interface with luck. If it is not wlan0, then substitute what you find for where I have used that in the second command.
Both of those need to be run from a root command prompt:
that's aminus sign and a space after the su. It gives you all of roots privileges when you run the commands.
Do you see anything in the NetworkManager software. You should have an icon for it in the notification area of the Gnome top panel, left clciking on if may reveal something.
Copy and paste the results of the first two commands back in a new post.
