Please add latest kernel update with WiFi fix to next Ubuntu "Snapshot" release

[Worcester12345]

Have successfully installed/updated to 26.04 and ran "Snapshot 2" and any subsequent updates to that. Initially, all was well I think, but then the WiFi started flaking out. I am using a Panda Wireless WiFi 6E AXE3000 model PAU0F USB adapter as seen here https://www.amazon.com/dp/B0D972VY9B?

This has never worked at the speed desired. I have iphones and Android phones and Windows and Apple laptops which all work at closer to 300Mb speeds, but this one has always been just over 100. Anyhow, after the most recent updates, it has stopped working completely.

I did some research online, and found these, among others:
https://www.phoronix.com/news/Linux-6.19-Fix-MediaTek-WiFi
https://www.webpronews.com/linux-kernel-6-19-reverts-code-to-fix-mediatek-mt792x-wifi-issues/

So, it seems there was indeed a fix to the kernel (actually, a back-out). I am just wondering if a bug needs to be put in to bring this code into the latest Ubuntu code base, and if so, will that make it into "Snapshot 3"?

Is there anything else I should or can do, to ensure that this happens, and is there any way for me to track the progress on this? Is there any way I can assist in moving this forward or testing anything to assist you in this?

Thank you

What kernel are you using? The problematic change you linked to was not added until 6.19-rc1
As far as I can tell, Ubuntu 26.04/Resolute is still using 6.18 kernel, and I'm not sure why they would backport the problematic change as it was not a security/critical fix.

I have 26.04, which has Linux 6.18.0-8-generic kernel. I do not touch any of that stuff.

If that is the case, then there is something else going on with this adapter. How should we proceed, then?

[Daniel Letzeisen (dtl131)]

You said it stopped working after most recent updates. If that batch included a kernel update, booting into the previous kernel to see if that works would be a good start.

Paolo Pisati will eventually bump the kernel to 6.19, likely when it gets a bit closer to release. (Its only at 6.19-rc4 at the moment).

If you want to keep an eye on things, Paolo places kernels in https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable before they go to the standard -proposed and -release pockets.

Resolute is likely to ship with 6.20 / 7.0, so it will be fixed eventually.

I also am experiencing this issue on 26.04 and I have a new Asus tuf mobo.

Hi, echoing what Daniel said, try rolling back the kernel and confirming that this is a regression with newer versions.

Keep in mind that the 26.04 snapshot kernel is closely following the upstream kernel, so you can expect some bugs that have yet to be fixed by the upstream kernel developers, and we are unlikely to attempt fixing them until after the kernel has stabilized on 6.20 in several months.

[Worcester12345 (worcester12345)]

Do you have a link to "rolling back the kernel"? It might make sense to just wait, if it is coming out in the next couple of days. I've received kernel updates along the way previously, and it was pretty seemless. Hoping this is the case. I've never done a kernel downgrade before, and prefer not to if possible. Thank you.

Ubuntu keeps at least one previous kernel as a failsafe. You are not "downgrading" the kernel. You're booting a previous one. https://askubuntu.com/questions/16042/how-to-get-to-the-grub-menu-at-boot-time
