Using 26.04.
My WiFi has now died. I am using a Panda PAU0F USB adapter.
I’ve read a few articles where they made a mistake in the kernel that did this, and have made the corrections in the kernel to fix it.
I am just wondering when this will come out in an update, and is it even existing yet as a bug on the Ubuntu side.
Thank you.
@worcester12345 Please stop cross-posting and hijacking threads. Your problem is unrelated to the thread topic. File a bug: ubuntu-bug linux.

For some reason, not given, my previous post was “reported” for something.
I am quite sure my post was not “offensive, abusive, to be hateful conduct or a violation of our community guidelines”, but it most certainly “adds to the conversation”. I have thought over what to say and am now trying with a new and corrected post.
I don’t recall “hijacking” anything. I thought the “Ubuntu Community” was supposedly warm and welcoming, as in the phrase: “Please treat this discussion forum with the same respect as would a public park. We, too, are a shared community resource — a place to share skills, knowledge and interests through ongoing conversation.”
Instead, I am being bullied/nannied, directly opposite of the advice quoted above, into looking elsewhere for information. I asked a very specific question, which probably has a very specific answer. Sorry you could not provide more helpful info here, but perhaps there are others who could, while following the community guidelines. The topic discussed here matters to me, and I wish you would act as if it matters to you, too. Be respectful of the topic and the people discussing them, even if you disagree with some of what is being said.
I am merely trying to find some information on a problem I am having with Ubuntu. I am trying to help with the testing of version 26.04, and am trying to report an issue and find a fix for this one specific problem, so that maybe this solution can also help others. Again, if anyone else has an answer, it would be greatly appreciated.
One way to improve the discussion is by discovering ones that are already happening. I may have a lead in another post on here, so will also be pursuing that. I have spent some time browsing the topics here before replying here. I hope I’ll have a better chance of meeting others who share that interest.
@worcester12345, your previous post would fall under the “Keep It Tidy” portion of the community guidelines that you linked, as it’s starting a topic in the wrong category (this being a general announcement of the kernel version to be included in 26.04). Please file a Launchpad bug in the prescribed manner above so our triage team can have a look.

OK. Sorry, but I did not see any other, better, place to put it.
I will have to find out how to do these launchpad bugs, and probably have to sign up to do it, then learn that system. If you have any guidelines or links on that, it would be greatly appreciated.
Hello, here is a link to a guide to file bug reports and other things on launchpad.
https://documentation.ubuntu.com/launchpad/user/how-to/work-with-bugs/index.html.

For a quick start, refer to this guide:
https://help.ubuntu.com/community/ReportingBugs
Please note that if your topic is related to a development release, like 26.04, the correct place to start a discussion is in the Pre-Release Discussion category.
However, we do not use that category for reporting bugs, this is done on Lanuchpad instead.

Moved to Pre-Release Discussion
Reminder: Pre-release software is not released and supported. It is in testing. Bugs and breakage are expected and routine.
We welcome testers who have basic testing and reporting skills, including how to troubleshoot problems and file bug reports.
Folks who are not comfortable with those requirements are strongly encouraged to use a supported release of Ubuntu, which includes community support to assist tracking down problems.

Using 26.04.

Thank you.
Ububtu version 26.04 is still an unreleased development version, and is still relatively early in the 6 month development cycle. Problems are to be expected, and help with those problems may not be forthcoming.
It would help us to help you if you provided links to your references articles, as that would help us to identify the actual kernel issue. Myself, I am getting no hits searching for “Panda” or “PAU0F”.
My best guess is this (and it is really a guess):
doug@s19:~/kernel/linux$ git tag --contains af7809f037e6
v6.19-rc4
Where:
doug@s19:~/kernel/linux$ git show af7809f037e6
commit af7809f037e6e56f63a4d66b6a02826ce786af2c

Revert "wifi: mt76: Strip whitespace from build ddate"
This reverts commit f804a5895ebad2b2d4fb8a3688d2115926e993d5.
This change introduced the following panic, and mt792x_load_firmware()
fails. wifi is dead on systems with mt792x wireless.
...
I don’t know how long that fix would take to propagate down to 26.04, but since it is fixing an issue introduced with kernel 6.19-rc1 I would say not long (if I have identified the correct issue).
doug@s19:~/kernel/linux$ git tag --contains f804a5895ebad2b2d4fb8a3688d2115926e993d5
v6.19-rc1
v6.19-rc2
v6.19-rc3
v6.19-rc4
If the issue has already been identified and addressed upstream, I wouldn’t bother filing a bug report on the Ubuntu side, but that is just me.

Reference
www.intel.com/content/www/us/en/support/articles/000005511/wireless.html
and 2 links here:
www.phoronix.com/news/Linux-6.19-Fix-MediaTek-WiFi
same as above
ending in Linux-6.19-rc4
“Among the fixes to land during this New Year’s holiday week were [fixing broken MediaTek WiFi driver support] for the MT792x wireless hardware and many smaller fixes throughout kernel space.”
So, it seems it was fixed in the kernel, and it is just a matter of time before it comes down to Ubuntu. I was just wondering whether that happens automatically, or if a bug needs to be reported for it to pick up that kernel update into Ubuntu’s updates. Is there any way of tracking this, so I could follow along?
Thank you.
So, my guess was correct. It will trickle down to Ubuntu automatically. Since this is all in the kernel 6.19-rc series it’ll be sooner rather than later.

Yes, you seemed to be correct. The only thing I was wondering was whether it needed a bug in order to track it. Any idea on that? Thank you.

OK. I am not 100% sure on what to do with this information.
So far, so good. I am new to the Ubuntu testing software and links, but am willing to learn, and someone else here has already started helping.
I’m comfortable with how to troubleshoot problems and submit bug reports in general. I have not yet done any for Ubuntu. I am willing to get started. Is Ubuntu willing to take the help?
Some additional info from a recent (today) Ubuntu update, related to WiFi, which just came in, in case this is helpful to someone else on here:
Technical description
Package: rfkill
rfkill is a simple tool for accessing the Linux rfkill device interface, which is used to enable and disable wireless networking devices, typically WLAN, Bluetooth and mobile broadband.
Changes for rfkill versions:
Installed version: 2.41.2-4ubuntu1
Available version: 2.41.2-4ubuntu2
If in doubt, open a new topic 
Not if you do not file it with ubuntu-bug linux… (launchpad will tell you in the first dialog if similar bug reports already exist and allow you to instead comment on an existing one if so …)
Especially when testing a pre-release your main job as a tester is to report issues via the bugtracker (only very few devs read the forum)

I did not realize this. I thought they were an integral part of this forum.
Thanks.
Is there a way to look around before signing up on this? Maybe this has already been addressed and is ready to happen. Thanks.
