My FreeBSD is unable to recognize a WiFi card

I have a PCI NIC card which I believe is D-Link DWL-G520. I had it in a very old box that I set up to act as an access point. The box was running FreeBSD 8.2 or 8.3. In any case, it is using AR5212 chip.

Everything worked fine, but today the machine gave its last breath and died.

I decided to move the NIC to another box that is more recent and is already running FreeBSD. The version is 9.1 RC3.

The problem here is that the card is not recognized, and by not recognized I mean I don't see it anywhere in pciconf output:

The machine's motherboard is Gigabyte GA-H77-DS3H, which has built in Atheros NIC (unlike the old box it is 64bit). I tried to compile various options, but no luck, here are relevant fragments of my config:

I'm running out of ideas what the problem could be. Please help.

Thanks,

Here's a similar post:
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2009-05/msg00518.html

The only difference is
Code:
chip=0x0013168c

I'm not sure how the various fields in pciconf are used to extract vendor and chip id in the driver (I know nothing about the ath driver), however I noticed that 0x168c is the Atheros vendor id and your chip id is missing that last 0x168c (yours shows 0x0000). I'm guessing the high order bytes 0x0013 correspond to AR5212 (the same as the link I provided and in ah_devid.h). Anyway, if something like vendor and chip id don't match up, then ath would never attach. Does it try to attach? (can you show dmesg?).

I checked ah_devid.h in /usr/src/sys/dev/ath/ath_hal.
 
The output of dmesg is attached.

The last line showed up due to me calling:
Code:
kldload ath_pci

You can probably force the attach by changing the atheros vendor ID to 0x0000 ... though I'm not sure if this has consequences. I would comment out the lines for ath* in your kernel config and build them as modules instead to experiment.

You probably should file a PR. I know Adrian is very quick to respond. I have submitted PRs about ath(4) before and he responds fast.
 
Hey, I just wanted to follow up and thank you for your help.

After contacting Adrian and following his suggestion by trying to check whether it works on Linux (it wasn't) after many experiments (I won't bore you with useless details, but if you really want it is archived here) it turned out that the connection was dirty, and application of isopropyl alcohol solved the issue :)

It's interesting that the card was partially recognized.

Anyway, thank you again for your help.
