My apologies Brakki, real life intervened...I didn't mean to drop this.
Have you gotten the card to work? I've been doing a little digging and from what I can tell, this is NOT an easy card to get up and running.
I hate to point you in this direction, but there is a HUGE thread on the WPC11 drivers
that seems to be relevant. You might skip to page 23 where finegan discusses the MA521 a bit. One of the themes that seems to run through that thread is that something happened with the kernel around 2.4.22 that caused difficulties for this card. I haven't seen if the 2.6.x kernels have worked. From what I can tell the kernel version is the single biggest obstacle to fixing this problem
Another relevant section from that thread would be on page 36 by prinaldi where he got it to work in Gentoo and details how. Also check out pg. 45 by Astro
I don't think I'm alone when I say that 10 or more lengthy steps are not acceptable to setup wireless networking. Please reply. What are the most significant challenges to this issue?
Perrond, the obstacle is the card manufacturers, plain and simple. My personal nemesis is Broadcom. They supply OEM cards to a number of vendors yet refuse to write linux drivers or (even more evil) refuse to release enough information for someone else to write one. Ndiswrapper really shouldn't be necessary but is because of the pigheadedness of some card manufacturers.
After a bit more reading, it looks as if the 2.6.x kernels may work. It looks like a kernel upgrade may be your best bet.
