Hi,
I am on travels so forgive if I miss things and will be selective with
my reply.
I'm having trouble with my wireless interface on a FreeBSD
13.1-RELEASE installed Laptop. The wlan0 interface that uses the
iwlwifi driver does not come up after booting. I have to bring it up
manually. I was advised to email this list as it is suspected to be
some issue with the driver.
I have a DELL XPS-13 9360 model laptop in which I've replaced the M2
slot wifi adapter with a wifi 6e adapter using an AX210 chip, wise
tiger is the brand name. I've properly configured wpa_supplicant to
join an AP in my home and I have the following options in /etc/rc.conf:
wlans_iwlwifi0="wlan0"
ifconfig_iwlwifi0="WPA DHCP"
The interface does not come up after booting the laptop. In
troubleshooting I've found that I can manualy bring the interface up
using the following commands:
# ifconfig wlan0 up scan
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf &
# dhclient wlan0
Once I bring up the interface, everything works as expected. I'm
composing and sending this email from the machine now that I've
manually brought up the interface.
I have no idea, why the interface does not come up automatically
following a boot. I've noticed errors loading up firmware for the
adapter and was wondering if this could be throwing off the timing
during boot?
Here are the iwlwifi messages logged during boot:
iwlwifi0: <iwlwifi> mem 0xdc100000-0xdc103fff at device 0.0 on pci2

How do you load iwlwifi? You are not by any chance doing this from
loader.conf?

Why is it attaching a 2nd time? Is this the same boot or did you
kldunload if_iwlwifi?

These next three were problems mostly from the past... I have not seen
them or heard from them in a while...
iwlwifi0: No beacon heard and the session protection is over already...
iwlwifi0: Not associated and the session protection is over already...
iwlwifi0: Not associated and the session protection is over already...
I hope someone here can help me to resolve this issue.
Most of these issues have been solved in main and (pending MFC for some)
will be sorted in stable/13 for 13.2.
So the 1st problem seems to be getting iwlwifi loaded and running and
wlan0 created.
The 2nd issue seems to be able to get wpa_supplicant to get it up and
then dhclient to get you an address.
Now the driver + LinuxKPI framework in 13.1-R (first release this
shipped after not too much time of having started to work) are missing
things and have bugs.
The other thing is that wpa_supplicant also got changes since. You
could try the port for that and see if it helps a bit but I fear you may
have to switch to stable/13 more likely (especially after MFCs are
done).
You can probably try to search the archive here or check
https://wiki.freebsd.org/WiFi/Iwlwifi
if there were any good workarounds found at that time.
I frankly have gone through too many details of all those to remember
at the moment.
hope this helps (at leats until next week),
