We use them mostly for client mode, but we do test them as access points as well.
I've only tested 32-bit kernels in AP mode, but 64-bit and 32-bit kernels in station
mode.  Will be testing 64-bit AP mode shortly.

It has some modifications..but nothing very significant for AP mode,
as far as I know.  It does have all of the stable patches applied, which
may help.

You may still see problems, and if you do, please let me know.  Not sure
I can fix anything, but post your hostapd conf file and such and I'll
see if we can reproduce the problem at least.  I have a couple of older
ath9k NICs lying around, maybe some with your chipset.

We also run with nohwcrypt enabled, so possibly that has some impact on
stability.

Thanks,
Ben
