Hello Bjoern,
My wifi card (AX201) doesn't seem to connect to a 802.11n network; it only
uses 802.11a
Connecting and using is two different things.
What does
ifconfig -v wlan0
say?
What does
ifconfig -v wlan0 list chan
say?
What does
ifconfig -v list scan
say?
Here's the card itself:
iwlwifi0@pci0:0:20:3: class=0x028000 rev=0x00 hdr=0x00 vendor=0x8086
device=0x02f0 subvendor=0x8086 subdevice=0x0070
vendor = 'Intel Corporation'
device = 'Comet Lake PCH-LP CNVi WiFi'
class = network
% grep AX201 /var/log/all.log
Mar 1 03:34:07 hamster kernel: iwlwifi0: Detected Intel(R) Wi-Fi 6 AX201
160MHz
Here's my OS info:
% uname -a
FreeBSD hamster 15.0-CURRENT FreeBSD 15.0-CURRENT #16
main-n275691-5b511473999a: Wed Feb 26 20:55:54 +05 2025

Here's what I chnged in loader.conf:
% grep linuxkpi /boot/loader.conf
compat.linuxkpi.80211.hw_crypto=1
compat.linuxkpi.iwlwifi_disable_11ac=0
compat.linuxkpi.iwlwifi_11n_disable=0
Another symptom would be that iwlwifi_disable_11ac doesn't seem to set to 0:
Did you reboot?
% sysctl compat.linuxkpi.iwlwifi_disable_11ac
compat.linuxkpi.iwlwifi_disable_11ac: 1
And iwlwifi_11n_disable, does that unset if you check the sysctl?
