I also had problems setting up this card under RH9 and Mandrake 9.2. A great thread to get a newbie started is this one:

I am still having a few interesting issues with this card. I am going to post in Hardware and see if anyone can help me solve it, as I've done everything I can think of to do. However, if it makes you feel better, I am using that Belkin F5D6020 ver 2 card to enter this post.
By the way, you need to make sure that your card is an F5D6020 version 2 (or ver. b) card, as Belkin switched the chipset from version 1 using the prism chipset, to an atmel chipset, which most Linux distros don't like right away. Read that thread and most of your problems will be solved.
