Its working stable!
I try to contact the pfsense core team about this option to be added in the future.
Shall I install 11-Current and continue from there with the testing?

hi,

you can do that. but I'm surprised there's no way in pfsense to
explicitly configure the channel as being ht/20 only.

You may find some devices won't let you tune to channel 13. It's all
very regulatory-y restricted.

I changed my settings to channel 13 since that is using only ht/20. Is that
ok for further testing?

no, you'll have to ask the pfsense people if they provided a UI to set

Ok, it's doing HT/40 in 11n mode, and you're on channel 3.

Try HT/20.

ok, so you have to use no-11n in order for it to be tsable, ok.

when you test, can you just verify that it's always using the same
channel?

are you using HT/20 or HT/40 when you're in 11n mode?

Besides that I had also a lot of these: ath0_wlan0: discard frame w/o
leading ethernet header (len 6 pkt len 6).

One night when WiFi stopped working then I came with my laptop in my
hand
to
sit in front of my router to do the usual ifconfig ath0 down/up but
before
doing that I observed that while I was near to the wifi antenna with
my
laptop the wifi started to work fine again without doing anything (on
laptop
the connection went from 15Mbps to 280Mbps automatically). I don't
know
it
this information is usefully to you. Of course this happened only one
time,
I tried next day the same and it wasn't enough.

Hi,

That's fine. Ok, try this:

ifconfig ath0_wlan0 -ampdu

.. then reassociate evryone.
