Can't detect intel wifi 6235

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1920180

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Please give the test kernel (https://people.canonical.com/~alexhung/LP1920180/) a try. It adds a new id to iwlwifi as below. If it works, a patch will be sent to upstream and stable kernels which will be picked up by Ubuntu kernel later.

Hi Alex Hung,

it works like a charm. thank you so much for your help, really appreciate it brother.
since i'm new to linux, is it alright to update anything after i try this kernel ?

It will take a while for a patch to be merged, so you will lose wifi 6235 if you update to newer kernels.

There are processes to merge a patch. A normal process is like below:

1. a patch is sent to upstream (cc to stable kernel)
2. it gets reviewed and merged by a maintainer, and is included in next kernel release
3. it gets merged to stable kernels (in this case, 5.4 kernel)
4. a kernel is released by a distro (i.e. in this case Ubuntu kernel)

Note: I don't know how Linux Mint picks up Ubuntu kernel and there may be some time too.

I will update status here if there is any

For references, the patch was sent and can be viewed @ https://www.spinics.net/lists/stable/msg452937.html

Hi Alex,

Really appreciate what you did for me. I hope lm could update it asap on
next kernel sir

Updates: the patch was not included in kernel 5.13-rc1 yet but I sent a follow-up email and let's see how this goes.

Dear Mr. Alex,

Thank you so much for your help and great information. I'm very excited
while wait for it to work.

There are still no responses from upstream so let me send SRU to Ubuntu kernels first.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed-hirsute'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
