Please try our latest version from https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-8265-36.ucode

This firmware is not upstream yet. I sent the pull request today.

Hi James:
Could you try the new fw of 8265?
If it works, I will try to pick the new fw to Ubuntu release.

I think the test and regression potential templates on this bug are not up to the normal SRU standard. There are a number of firmware blobs updated, what is the set of chips that make use of these firmware blobs that could potentially be affected by this update? Why is this complete range of firmware blobs being updated, if there is a bug being reported with only a single chip?

Seth Forshee (sforshee) wrote :

It is because of the way Intel updated the firmware upstream. The updates which brought in the fixes wanted for 8265 wireless also updated these other files, and since the upstream changelog doesn't provide any specifics about what fixes the updates contain we don't know whether or not the update contains the same fixes in the other firmware files. In the past we've generally just pulled in the bundle of updates where the fix was identified. Perhaps Emmanuel can chime in with more information (though I'm pretty sure he'd prefer we were always pulling in the newest firmware anyhow).

Otherwise, I can back out the updates for the 7000 and 9000 series if you prefer.

Seth, my only preference here is that the test cases be appropriate for what's being updated. If there are going to be updates affecting multiple series of chips, then I think the test case should also cover testing across multiple series. Otherwise, if that testing is onerous, I think withdrawing this SRU and changing only the firmware for the series we know is affected by this bug would be better.

Hello James, or anyone else affected,

Accepted linux-firmware into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/1.175.3 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 and change the tag from verification-needed-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. 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.

src:linux-firmware is only accepted into cosmic-proposed but still waiting in Bionic-unapproved.
AFAIK the current status of "Fix committed" will make it not to be seen by the SRU Team (at least for similar cases I had in the past).
Therefore to increase the chance to get also the Bionic portion accepted into -proposed lets dial back the current status of the bug task.

Thanks for accepting that into Bionic-Proposed.
I have switched to 1.173.5 from Proposed and unplugged the cables.

The install (a downgrade for me as outlined) itself worked fine, I'll reboot now and check on Monday I'll check if any connectivity issues came up over the weekend.

Therefore I'd think this firmware in proposed is as good as the PPA I used int he last time.

Let me make sure it loaded the right FW ...
Ok, yeah it switched I have loaded
- 36.7596afd4.0 (from my PPA)
- 36.9f0a2d68.0 (from proposed)
- 36.e91976c0.0 (and all of 22.x - 36.x when it was failing)

Since back than I had a short time where it failed even with 36.7596afd4.0 (probably due to all the debugging I had enabled, but not for sure) I'll declare my test alone not sufficient for the verification. But from my POV at least it seems good (If no other reporter tests proposed at all you might take that as verified for Bionic, I have no system to test the same on cosmic).

I have a problem that looks very similar to this one, but it's happening with linux-firmware 1.173.9 and only on my home 5 GHz SSID (the 2.4 GHz SSID connects fine). What do I need to send you in order to have it fixed?

I started getting this after getting a new router. The router I had before didn't trigger this.

I'm seeing this very same issue on a new Lenovo T590 running 19.10 with linux-firmware 1.182 and linux-image-generic 5.3.0.10.11. See attached files for more verbose info on the network controller and journalctl logs.

Thanks to the previous comment, I can say that the issue is only seen if the system connects to a 5GHz network.

Ok, this is a complex matter. I just experienced this unpleasant feature on my laptop using the above described driver and hardware for the last two days. =>It seems to be a radio transmission issue.<=

The Linux driver as well as the microcode of the WiFi device must be able to cope with the small frequency jumps of the access point. Yes, frequencies are =>NOT<= very stable. This is shown in the logs by the following messages: wpa_supplicant[971]: wlp1s0: CTRL-EVENT-SIGNAL-CHANGE. When this event occurs, your hardware must resync with the access point. The driver as well as the microcode of your WiFi device may or may not support such a frequency jump. In other term they may or may not be able to cope with the noise. The following log message shows that my system was not able to cope with it: iwlwifi 0000:01:00.0: Microcode SW error detected.

What actually solved the issue is re-configuring the access point. I limited the channel width on the 2.4 Ghz frequency to 20 Mhz to avoid interference with other access points in the area. In addition I defined a precise channel for the access. For the channel selection, prefer channel 1, 6 or 11, since they do not overlap. Now my connection is stable and my logs are clean.

For the 5 Ghz network, these problem might not occur as frequently as on the 2.4 Ghz one, since it is less used. In case similar issues are faced, proceed similarly.

Hope it helps, Illi

Comment #28 seems to offer some good insights about the best path forward here, also supporting that this bug should be reopened. Note that with a Google Wifi router, there is no capability to reconfigure the router to work around this issue, as the poster mentions.

I have similar problem with similar dmesg output with Lenovo T480 (Intel 8265 wifi) and Huawei router.

The problems started after upgrading from 18.04 to 20.04.1 about a week ago.

I just found out that my Lenovo dock also affects this situation -- when I undock my T480, wifi starts working properly. (No, the dock doesn't have ethernet cable attached.)

Still, I had problems already before starting to use the dock, but wifi performance was bearable then. With dock it is not.
