Running FreeBSD 13.1-STABLE (FreeBSD 13.1-STABLE #86 stable/13-n250051-ddb842e2ad6: Sun
Mar 20 20:49:26 CET 2022 amd64), using if_iwm is a horrible mess and almost unusable
(configured both re0 and wlan0 as "lagg0").
I tried - several time since iwlwifi is available for FreeBSD 13, iwlwifi, but without
any success.
I have to load if_iwlwifi.ko via /boo/loader.conf[.local], since outoloading iwlwifi does
not work by defining
wlans_iwlwifi0="wlan0"
in /etc/rc.conf. Loading iwlwifi via /boot/loader.conf.local leaves me with two problems:
first, the firmware does not load, although setting these lines in /etc/rc.conf.local:
# Intel WiFi driver for Linux
if_iwlwifi_load="YES"
iwlwifi-7260-17.ucode_load="YES"
(also tried:
# Intel WiFi driver for Linux
if_iwlwifi_load="YES"
iwlwifi_7260_17.ucode_load="YES")
I'm not aware but I might remember that there is a rc script issue causing this regarding
the "_" and "-" interpretation. So the weird part is, that something alway load the
if_iwm.ko module additionaly and I have no clue were this comes from.
Without manual intervention dmesg reports this error:
[...]
Intel(R) Wireless WiFi based driver for FreeBSD
iwlwifi0: <iwlwifi> mem 0xf1c00000-0xf1c01fff at device 0.0 on pci4
iwlwifi0: could not load firmware image 'iwlwifi-7260-17.ucode'
iwlwifi0: File size way too small!
iwlwifi0: no suitable firmware found!
iwlwifi0: iwlwifi-7260-17 is required
iwlwifi0: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Loading the firmware manually by typing
"kldload /boot/kernel/iwlwifi-7260-17.ucode.ko"
does finally load the firmware, but there is no wifi adpator at all ...
Kind regards,
oh
