Why do you need to rename the firmware files? What version of ath6kl are
you using? Where did you get it?

You should be using fw-3.bin. Better to remove athwlan.bin and fw-2.bin
altogether from your platform.

I think I don't have AR6103 myself. I'm not sure if it has some
differences compared to AR6003, that's one possibility as well.

I haven't renamed files except for the data file. I had to rename one of three bdata files, otherwise I got error from the driver that it wasn't able to load the bdata file, because it couldn't find it. I tried all combinations fw-3.bin only without athwlan.bin, fw-2.bin without athwlan.bin and so on but without success ;-(
I downloaded ath6kl FW from kernel firmware git repository and I'm using linux kernel 3.4.5 downloaded from kernel source tree, I know that you use some other repository for downloading Kernel but I also downloaded that before we were introduced and made a diff with my kernel on ath6kl drivet and there are practically no changes between the two in loading and powering up the modulei to the point where my module doesn't reply anymore? If you downloaded F ath6kl FW from some other repository, could you please tell me the URL?

I actually did that. As explained above I tried different combinations also using fw-2.bin or fw-3.bin without athwlan.bin being present in the corresponding FW folder. But things were even worse ;-(

Hi Kalle,

Could you please tell me what are the binaries for AR6103 to function properly
and where can I download the FW and the corresponding binaries. I would like
you to send me proper FW files if possible. I actually don't know what is happening
but as I explained after uploading FW to the WiFi module, there communication
error occurs.

I would like to thank you for all your help and information.

Best Regards,
Ales
