Sorry, it seems like the newlines and paragraphs didn't work out as intended. I 
hope this is more readable now:


I'm new to FreeBSD. I decided to install 9.0-RELEASE (amd64) on a machine I 
have been given, which has a PCI WLAN card installed.
After booting the newly installed system, I ran ifconfig, which however only 
shows fxp0, plip0 and lo0.
I tried to google for users with similar problems and follow suggestions made 
by others in hopes to fix the problem. In the process, I compiled a new kernel 
with AH_DEBUG and ATH_DEBUG and created /boot/loader.conf with the two 
following lines:

Since I do not have a network connection of the affected machine, I will only 
type in the part of the dmesg output which I guess could be relevant. If you 
want, I could try to find a USB drive or something similar to post the whole 
dmesg output.

ath0: <Atheros 5413> mem 0xfdee0000-0xfdeeffff irq 16 at device 4.0 on pci2
ar5212ChipTest: address test failed addr: 0x00008000 - wr:0x00000000 != 
ar5212Attach: hardware self-test failed
ath0: unable to attach hardware; HAL status 14
device_attach: ath0 attach returned 6

I tried a Ubuntu live-CD, which recognised the WLAN card and allowed me to 
connect to my network and browse the web.

I don't know what I could do to solve this issue. I'm willing to try various 
things, especially since this machine is not in any way in productive use right 
now (and there is no valuable data stored either.)

Being quite proficient in C and C++, I wouldn't mind if your suggestions 
involved me looking at some code and modifying it in some places. However, 
please keep in mind that, since I'm a new FreeBSD user, I'm have no idea about 
the inner workings of the FreeBSD code (although I had brief look at the ath 
sources prior to writing this mail.) Also, I don't know anything about 
programming hardware, and I don't know much about IEEE 802.11 either.

I would be very thankful for all kinds of input. Please let me know if you need 
further information.
