Description

Occasionally, my WiFi adapter will stop working. Clients lose their connection to it, and if I scan nearby WiFis with my cell (using SatStat, https://mvglasow.github.io/satstat) my AP no longer appears in the list.

I have tried disabling and re-enabling the adapter in the Web GUI (applying canges after each step), but to no avail. I need to reboot to get the adapter back to life.

I have been running this setup for a few weeks now. I encountered the issue once in 2.1.4 during setup. I upgraded to 2.1.5 a couple of days ago and noticed yesterday morning that the WiFi was down. I investigated in the evening, eventually rebooting, and got the WiFi back to life. Tonight, as I was working, I noticed that the WiFi once dropped out briefly, then came back. About one or two hours later the WiFi dropped out again, this time for good.

I am seeing the following entry in the log file:

Sep 5 22:15:37 kernel: ath0: stuck beacon; resetting (bmiss count 4)

Just rebooted and WiFi is back again. I still get the stuck beacon message in the system log, but less frequently than while the WiFi was down (at that time I got some 4 messages per second, now the rate of messages varies, 1 message per second on average, with gaps up to 5 seconds).

Wifi's gone again, after just 75 minutes of uptime. Wireless log attached.

Update: after the last loss of WiFi I just left everything alone and the next morning I noticed the WiFi was back (though later the same on-off game started over again).

Therefore I can't tell for sure if the WiFi is ever gone for good or if all failures are just sporadic in nature and the WiFi eventually recovers by itself.

In any case, this behavior is rendering the WiFi adapter completely unreliable and thus unusable.

I have downgraded to 2.1.4 (i.e. reinstalled 2.1.4 from scratch and restored config). I noticed that after the first few reboots the WiFi adapter was not detected at all, after a few reboots it was there again and I could configure it.

I'll watch the setup for a few days and will post if going back to 2.1.4 improves the situation.

I had the same issue, with nearly the same setup (APU 1D4 engine).

What really helped me, was to set the Wireless Standard to 802.11b. Unfortunately you're now limited to 11Mbit/s.

The other wireless settings are the same as yours.

driver issue that's outside our control, and is almost certainly fixed in 2.2's base OS.

I have a similar issue with an "APU3 C2" board since upgrading pfSense from v2.4.5p1 (FreeBSD 11.3-STABLE) to v2.5.0 (FreeBSD 12.2-STABLE)

Symptoms
WiFi lost after some working hours.

Workaround
Restart pfSense each time the issue appears.

I can see these new improvements with FreeBSD v12.2 :
"Updates to the wireless networking stack and various drivers have been introduced to provide better 802.11n and 802.11ac support."
