Problems with Atheros AR5006EG 802.11 b/g Wireless Adapter

The problem is quite simple; I can't get Fedora to detect the card no matter what I do. If I try the Madwifi drivers, I'm hampered by the following problem:

Quote:

Yeah, according to Fedora, the wireless card isn't really there, even though I know it is. It shows up in lspci, though.

Because I can't see it, I can't get it to work with the Madwifi drivers.

I also tried using the Windows driver through Ndiswrapper. It works in Kubuntu and openSUSE, but in Fedora using Ndiswrapper with this particular driver causes a kernel panic:

Trying different kernels had no effect at all; all of them either crash this way or give me a list of similar errors (only instead of forcing a restart, it simply prints the error over and over again). I'm about out of ideas now...

I, too, have the same issue...

It (ndiswrapper) freezes the system solid when you try to do anything w/ it including activating 'wpa_supplicant' service or simply editing through system -> admin -> network. No issue(s) w/ any other distro except F7.
