22.04 802.11 (wifi) firmware failure

Question

I just updated in place (no new harddrive, no new partitions) from 20.04LTS to 22.04LTS. Everything worked except that there is a firmware loading diagnostic (along with a separate failure to compile the VMWare kernel support -- but that may be a VMWare issue, not Ubuntu). Thus, the 802.11 hardware is NOT "seen" by the kernel, etc. (I am using bluetooth to Android phone to our 802.11 network to get to the Internet right now -- not the laptop 802.11). The relevant section of the dmesg log seems to be:

and more. The machine is a HP Zbook G2 that had no issues with Ubuntu 20.04LTS. Any help would be appreciated. Would it work to downgrade the firmware .deb to 20.04LTS or would this be not compatible with the current 22.04LTS production kernel or environment? If downgrading would work, please provide "detailed" instructions (e.g., the apt command invocations to use).

My apologies -- I read "edit" but understood that to be "reply". In the very limited and controlled Ask Ubuntu system (unlike the Scientific Linux Users List, now effectively defunct with the end of Scientific Linux), only the original posting can accommodate the length of output requested. Here it is:

Is this a dual-boot with Windows? https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled — chili555, Apr 28 '22 at 20:36
NO -- under no circumstances would I consider a dual-boot unless the two OSs are on separate physical hard/ss drives and that under no circumstances could MS Win access the Linux drive. I do use Virtual Box, VMWare, and, for the few situations possible, CrossOver (supported licensed for fee WINE). — Yasha Karant, Apr 28 '22 at 22:11
The internal Intel 7260 802.11 "card" still does not work under 22.04LTS -- firmware issue. So as not to transfer through bluetooth to an Android "smart" phone that does connect to our 802.11 access point, I just purchased and installed a USB 802.11 unit that is advertised to and does work with Ubuntu; I did not even have to reboot (but did have to enter the 802.11 security sequence -- NetworkManager had not retained this information). The USB device is Panda N600 Dual Band (2.4GHz & 5.0GHz) 300Mbps Wireless N USB Adapter w/WPS Button https://www.amazon.com/dp/B00U2SIS0O — Yasha Karant, Apr 28 '22 at 22:18
Until such time that Canonical releases a fix (revised firmware?) for 22.04 LTS to solve this issue, is it feasible to downgrade the firmware .deb file/files to those from 20.04 LTS? Or, is the 20.40 firmware incompatible with 22.04 LTS? If it is feasible, which .deb/s should be used and what are the specific commands / syntax to accomplish this? — Yasha Karant, Apr 30 '22 at 01:47
I am not convinced it is a bug that Canonical, or the actual author of the driver and firmware, Intel, need to address. My own 22.04 system uses the Intel 7260, loads the same firmware version and works perfectly. Viz: loaded firmware version 17.3216344376.0 7260-17.ucode op_mode iwlmvm As well, on AU and Ubuntu Forums, yours is the only case I've seen. I would like to see the size of your firmware file: ls -al /usr/lib/firmware/iwlwifi-7260-17.ucode We hope the size is 1049340. — chili555, Apr 30 '22 at 02:39
Note the same size here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ Also note the log shows that the firmware file hasn't changed since 2018; certainly not between 20.04 and 22.04. Can you run a live session of 20.04 where the wireless works correctly? — chili555, Apr 30 '22 at 02:41
-rw-r--r-- 1 root root 1049340 Mar 28 23:17 /usr/lib/firmware/iwlwifi-7260-17.ucode``` Any other suggestions? Note that another user of the same computer model as I am using has the same issue. It may be an issue in the current Linux kernel and associated kernel "applications" that has the issue -- in which case, does one downgrade to a previous kernel? Again, the same hardware was NOT an issue with 20.04LTS and routinely installed the latest nobeta kernels presented by Software Updater. — Yasha Karant, Apr 30 '22 at 03:04
I note that the G2 was introduced in 2014. Has your BIOS been updated? — chili555, Apr 30 '22 at 11:21
How does one "update BIOS" from Linux? The last time I had to do this I had to remove the harddrive, put in the OEM MS Win 7 harddrive (NO LONGER SUPPORTED and I have not updated a harddrive beyond this) and used the HP web site. Note that 20.04LTS current (and before that, Scientific Linux current) had NO issues -- only 22.04LTS has an issue. Any idea why? — Yasha Karant, Apr 30 '22 at 15:46

In the latest software revision (I installed the latest production Ubuntu 22.04 Linux kernel and kernel related packages as provided by the Software Updater Ubuntu application on 28 June 2022), the issue has been resolved. During a normal reboot after the kernel "upgrade" the on-board (not USB plug-in) 802.11 chipset is recognized by Ubuntu and the network manager application and seems to function as well as it did under 20.04 LTS. Thus, the issue evidently was a software defect ("bug") in either the executable source code, the building thereof to a .deb file, or an interpreted configuration file/s -- not a hardware issue with the HP Zbook G2. Again, the problem seems to have been solved.

Could you add more details to your answer? As such, it relies too much on the link you refer to and that could disappear. Add to which file to add what you suggest and how. Leave the link as reference. – Marc Vanhoomissen May 30 '22 at 10:25

The comment by chili555 helped with iwlwifi on a Thinkpad P15 that had been updated to Ubuntu 22.04 and linux-firmware 20220329.git681281e4-0ubuntu3.2. The solution was to hold down the power button for 5 seconds to power cycle the laptop. Soft reboots would consistently result in wifi failure and the following dmesg entries:

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review — Pilot6, Jun 23 '22 at 19:53
This does provide an answer. The answer is to try a full power cycle because the intel wifi firmware appears to be sensitive to fast, soft or otherwise accelerated reboots. — HueyDeweyandLouie, Jun 24 '22 at 20:09
The comment concerning a ThinkPad does not address my experience on my HP Zbook G2 laptop. I did full cold boots, not re-boots, not soft boots. The issue concerning timing would indeed be consistent with what I could observe from the scrolling text terminal messages on the screen during boot; there indeed could have been a specific wait interval between booting sequence operations that was not being obeyed by the previous 22.04 kernels and related code but it did not seem to be a stochastic race condition in that the Linux "wifi" system NEVER worked with the on-board hardware — Yasha Karant, Jun 29 '22 at 05:12
