Are there any simple guides around on how to set up a PCI wireless card on an A1200 with a Mediator?

Also, are there any tips on what cards work/don't work?

That's if PCI wireless is even possible.

I currently have it set up with a Realtek PCI ethernet card which works well, but I would like to change to wireless so I can use the system without uncoiling an extremely long ethernet cable.

Using a PCMCIA card isn't really possible as the tower case prevents it.

Thanks
