I've been using a budget-line Compaq laptop which has an AR242x wireless controller from Atheros. It was running out of the box when I first put 8.10 on the system, but future kernel upgrades stopped the drivers from working - so I'd just been booting into an old kernel. After upgrading to 9.04, however, it was working out of the box again - until I rebooted, and presto! the wireless card was no longer detected by the system, even though there was supposedly an active proprietary driver.

I went to the compat-wireless site, downloaded and made the package, and after typing "make load," it appeared to work. Here's what I got.

ath5k loaded successfully
Module bcm43xx not detected -- this is fine
b43 loaded successfully
b43legacy loaded successfully

My networking applet now shows a "wireless networks" tab, but cannot see any networks. Further, I installed the wifi-radar package, to make sure it wasn't somehow a problem with GNOME and not the hardware drivers, and the terminal output says:

wlan0 Interface doesn't support scanning : Device or resource busy


Does anyone have any idea how I can resolve this issue and get my wireless back up and running? If going back to proprietary drivers will work, I'll do it - but I think that was what was working and stopped for no particular reason.
