[SOLVED] Wireless card no longer works after update

Hi,

My system has an Intel Wireless 8265, and after updating my system it no longer seems to work.

I'm not sure how to even parse what's going on in dmesg, it looks like the card won't come up because it doesn't return a temperature value?

*edit: I tried booting with kernel 5.2 instead of 4.19-lts and the card works, but only after disabling->re-enabling it in Network Manager's applet, and there are still crash traces in my syslog.

Re: [SOLVED] Wireless card no longer works after update

Firmware bugs, do you have a log (journalctl will be your friend here) from a working boot?  There are a few things to try here:

1. Nudge it to load an older firmware:

   mv /usr/lib/firmware/iwlwifi-8265-36.ucode /usr/lib/firmware/iwlwifi-8265-36.ucode.bak

2. Alternatively downgrade linux-firmware to a working version, that's a bit of a shotgun approach since that will downgrade all otherwise working firmware as well

3. Pick up an older (or newer!) revision of the -36 firmware specifically.

Re: [SOLVED] Wireless card no longer works after update

Thank you for the troubleshooting advice, V1del.

I ran `mv /usr/lib/firmware/iwlwifi-8265-36.ucode /usr/lib/firmware/iwlwifi-8265-36.ucode.bak` and restarted. The wireless card still seems to crash though. It looks to me like it's falling back to -34 for the card to work?

But even then I cannot join a wireless network until I disable and re-enable the card after logging in.

This less-severe issue (where I can join after toggling the card) has been going on for months now, I'm not sure if I can find a clean boot in journalctl but I'll take a look around.

How do I tell which version of -36 I have?

Re: [SOLVED] Wireless card no longer works after update

ls /usr/lib/firmware/iwlwifi-8265*
/usr/lib/firmware/iwlwifi-8265-21.ucode
/usr/lib/firmware/iwlwifi-8265-22.ucode
/usr/lib/firmware/iwlwifi-8265-27.ucode
/usr/lib/firmware/iwlwifi-8265-31.ucode
/usr/lib/firmware/iwlwifi-8265-34.ucode
/usr/lib/firmware/iwlwifi-8265-36.ucode

If you also move /usr/lib/firmware/iwlwifi-8265-34.ucode does iwlwifi then fallback to iwlwifi-8265-31.ucode and if so is the issue still present?
Edit:
Looking at the kernel source for linux 5.2 you should be able to use ucodes down to -22.

Did that, issue persists.

I'm going to backup -31 as well and try forcing -27 next.

OK, still doesn't work properly on -27.

Re: [SOLVED] Wireless card no longer works after update

I found that I had set some driver variables:

$ cat /etc/modprobe.d/iwlwifi.conf
options iwlwifi power_save=1 d0i3_disable=0 uapsd_disable=0
options iwldvm force_cam=0

So I tried moving iwlwifi.conf to iwlwifi.bak and rebooting. The wireless appears to work properly now, and I do not need to toggle it after booting the system anymore.

V1del, loqs, thank you both for helping me sort this out.
