Hello Bjoern,
I'm using AX201 @ main-n276448-a1adefb139b3

Okay, that explains and hw_crypto is indeed disabled (avoids the TKIP<br>
problem) and my fallback caught this disabling AMPDU-RX. Good.<br>
<br>
Though I am still wondering why the AX201 does not freak out given it cannot<br>
decrypt frames when doing HT. Some hoemwork for me tonight to test on<br>
AX200 or AX210 w/ and /wo VHT enabled. I hope some others are reading<br>
along as they may be curious to try this too.<br>
<br>
Did you do change the hw_crypto and iwlwifi_disable_11ac value yourself<br>
(in loader.conf.local) or did the firmware update not do the right thing?<br>
<br>
For me it looks like:<br>
<br>
cat /boot/loader.conf.d/iwlwifi-ax210.conf<br>
compat.linuxkpi.80211.hw_crypto=1<br>
compat.linuxkpi.iwlwifi_11n_disable=0<br>
compat.linuxkpi.iwlwifi_disable_11ac=0<br>
<br>
I am just asking in order to catch any possible general problems early.<br>
If you've done it manually then that's all fine.<br>
