For about 5 years now I have:

Everything is perfects upon device's fresh config and init.
There were and always are problems with this card, AFTER some time passes.
It's like it simply becomes unresponsive.
Now at 12.2-RELEASE-p3 - i386, after some time passes:
1) As station/client => in associated state it simply stops transmitting
packets
It can't ping it's AP!
# service netif restart ..., "fixes" issue.
2) As AP => it ignores it's clients and simply stops transmitting packets
And WORST, slowly but surely freezes whole OS!
Even console becomes unresponsive and only hard reset helps!
Where should I look at?
What should I do?
PS: Take a note that SAME setup poses no problem for:
--
ath0@pci0:3:1:0: class=0x020000 card=0x3a131186 chip=0x0013168c rev=0x01
hdr=0x00
vendor = 'Qualcomm Atheros'
device = 'AR5212/5213/2414 Wireless Network Adapter'
class = network
subclass = ethernet

I saw in section 'Known chipset issues/limitations/bugs':
interrupt read-and-clear bug
Has anyone yet found a way to deal with it?
PS: freebsd-wireless@ => I'm not on a mailing list, so keep me posted.
Thx in advance,
