Okay, that explains and hw_crypto is indeed disabled (avoids the TKIP
problem) and my fallback caught this disabling AMPDU-RX.  Good.

Though I am still wondering why the AX201 does not freak out given it cannot
decrypt frames when doing HT.  Some hoemwork for me tonight to test on
AX200 or AX210 w/ and /wo VHT enabled.  I hope some others are reading
along as they may be curious to try this too.

Did you do change the hw_crypto and iwlwifi_disable_11ac value yourself
(in loader.conf.local) or did the firmware update not do the right thing?

For me it looks like:

cat /boot/loader.conf.d/iwlwifi-ax210.conf
compat.linuxkpi.80211.hw_crypto=1
compat.linuxkpi.iwlwifi_11n_disable=0
compat.linuxkpi.iwlwifi_disable_11ac=0

I am just asking in order to catch any possible general problems early.
If you've done it manually then that's all fine.

Great!


Lots of joy,
