Ubuntu 22.04 XPS 13 plus 9320 kernel 6.0 OEM and 5.19 breaks wifi frequently

Hello,

Could you try the latest pnvm file to see if it improves the issue?
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/tree/iwlwifi-so-a0-gf-a0.pnvm

Or copy the attached file to /lib/firmware and reboot.

Thanks,

Attach firmware for #2.

622e1bc1a7a94deb424bbc3dde7fce37 iwlwifi-so-a0-gf-a0.pnvm

Hello, unfortunately that file did not help. I get the same error. To confirm I did this right

md5sum /lib/firmware/iwlwifi-so-a0-gf-a0.pnvm
622e1bc1a7a94deb424bbc3dde7fce37 /lib/firmware/iwlwifi-so-a0-gf-a0.pnvm

I rebooted with 6.0.0-1011-oem and got the same error with Loaded firmware version: 72.daa05125.0 so-a0-gf-a0-72.ucode in dmesg.

Another observation that maybe someone can help me clarify. I suspect that this bug only affects newer wifi routers, possibly only 6E. The problem always happens at my home router (Nest Wifi Pro with 6E) and not my work router (older, though does support 5Ghz).

I don't know how to get a more precise reading of the wifi router capabilities from Ubuntu. Both say "Link speed 5.7Ghz" in Wi-Fi settings. Let me know if there is anything further I could post to help debug.

Hello,

Could you install intel backport iwlwifi wifi on your system? and replace the firmware file by the attachment to /lib/firmware.

u@u-Precision:~/Workspace/iwlwifi-linux-firmware$ md5sum iwlwifi-so-a0-gf-a0-73.ucode
f374c4f9043c785f74a6574edea6db83 iwlwifi-so-a0-gf-a0-73.ucode

890f1a5e9e62f355edc1900157d85c4b iwlwifi-so-a0-gf-a0.pnvm

You can install Intel backport-iwlwifi by
$ sudo apt install linux-modules-iwlwifi-generic-hwe-22.04
$ sudo reboot
You should see the kernel log that loads the -73 ucode.
Please be aware to boot into 5.19.0-32-generic.

Also, could you dump the country code setting on your machine by
$ iw reg get
The link info by
$ iwconfig
Phy capability info by
$ iw phy0 info => be aware you don't have other wifi card on your machine, otherwise the index might change.

Attachment for #7.

Hello, so far so good. Wireless hasn't failed today. Using your provided files and 5.19.

Did you install backport iwlwifi, linux-modules-iwlwifi-generic-hwe-22.04?

reply #9,

The iwconfig seems empty, can you use command below instead, devname can be obtained by $ ip link
$ iw dev <devname> info

I installed the backport iwlwifi package.

$ sudo apt install linux-modules-iwlwifi-generic-hwe-22.04

Hello,

Could you help to confirm that the updated bin file #8 solves your problem, so that we can proceed SRU for it.

Thanks,

I attempted this and booted into kernel 5.19.0-32-generic however I then had no wifi at all. The option to connect no longer existed in the top right corner.

Prior to this, it failed in the same way, with Microcode SW error detected, a second time today. It does seems like it happened less often but it's hard to prove that. I switched back to 5.15 for now so as to have a usable computer.

Do you mean you are not able to install new driver firmware by step in #21? Did you disable secure boot? Since the step didn't include module signing, your system can't load it if the secure boot is enabled.

To the best of my knowledge, I followed the steps you outlined cloning both repos and installing/cp'ing the files. I've double checked the firmware files exist. When I run "update-grub" just to check, I see

Found linux image: /boot/vmlinuz-6.0.0-1012-oem
Found initrd image: /boot/initrd.img-6.0.0-1012-oem
Found linux image: /boot/vmlinuz-5.19.0-35-generic
Found initrd image: /boot/initrd.img-5.19.0-35-generic
Found linux image: /boot/vmlinuz-5.19.0-32-generic
Found initrd image: /boot/initrd.img-5.19.0-32-generic
Found linux image: /boot/vmlinuz-5.15.0-67-generic
Found initrd image: /boot/initrd.img-5.15.0-67-generic

When I boot, I pick 5.19.0-32-generic. That is what I should pick, right? I'm not familiar with how drivers are selected for each kernel nor how exactly the backport-iwlwifi make and make install actually work, but it looked successful.

Before running the commands, it appeared that kernel 5.19.0-32-generic would have the wifi error once a day or so. After I ran the commands and rebooted, I had no internet at all. That also made it difficult for me to look up any commands necessary to provide more information.

I can try other things if that is desired. This is my primary computer and I need to use kernel 5.15 to get work done, so it may take me a day or so to respond. This is the only device that has failed. My Android phone and other family Ubuntu computers do not have a problem with the same wifi router.

I wonder if it only fails when it happens to use the 6Gz frequency? Is it expected to see that when running iw dev wlp0s20f3 info? Does center1: 5775 MHz mean what a lay person would call "5Ghz" and the MHz would be above 6000MHz if it was using "6Gz"? Once the wifi crashes, I don't know what frequency it was recently using. Another perhaps less common thing about the Nest Wifi Pro is that it's a Mesh network with two access points.

Actually, the $ sudo make install for backport-iwlwifi will only be installed into the kernel you build it, it will not install itself to all the kernel version.

To fix your firmware issue we usually try the latest firmware but it needs to update the driver to bump the ABI for loading the new firmware.

If it is okay, would you please try to build it on 5.19.0-35-generic and boot into 5.19.0-35-generic kernel. Of course, please do it when you are available, don't bother to do it immediately since you already have a stable 5.15 kernel for your daily work. The reason that I suggest you to try it is because I can't reproduce it with my Netgear Nighthawk AP.

Thanks for your understanding,

Thanks, I think I'm now using 5.19.0-35 with the new driver. I'll monitor for crashes. Is there anything in particular I should look for in "journalctl -k -b"?

Hello,
Just to tell I have the same issue, but do not get the technical skills to build kernels.

I attach journactl log if it may help....

Reply #27

Could you try steps in #21 to see if it helps?
Please disable secure boot after reboot.

Thanks,

Reply #28

I am sorry, but this is my daily workstation (I'm Freelancer) and I don't want to take the risk to break it for the next days (lot of work to do! :) )... :/

Status changed to 'Confirmed' because the bug affects multiple users.

reply #29

Would you like to try #7 and #8? it doesn't need to compile anything.

Hello David, or anyone else affected,

Accepted linux-firmware into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/20220329.git681281e4-0ubuntu3.11 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I have done an apt update on classical chanel 2 hours ago and it works like a charm now :) (even latencties problems are gone!)

But i have also installed a VPN wich had maybe changed things ion the config... I put log of the install in attachment.

reply #34,

The linux-modules-iwlwifi-generic-hwe-22.04 just provide an alternative intel wifi driver which loads later Intel firmware for your system, I think install any userspace package won't impact it, unless you install new kernel without upgrading the package against the new kernel.

the firmware in #8 is in jammy-proposed now, please keep monitoring to see if you still suffer from the issue you met before.

Thanks,

After an apt update && apt upgrade on stable chanel, and then reboot, the problem is still there...

Hello,

From the log, you are not using the fixed firmware which is 73 ucode, Could you check if you have linux-modules-iwlwifi-generic-hwe-22.04 installed?

How to check:
$ apt policy linux-modules-iwlwifi-generic-hwe-22.04
$ apt policy linux-firmware
Check your running kernel
$ uname -r
Please upload the full kernel log by $ journalctl -k -b.

Of course :)
