Intel AX201 WiFi card not recognized

Question

I have a Samsung Galaxy Book Flex2 Alpha with an Intel AX201 WiFi card dualbooting Windows 10 and Ubuntu 20.04 (now 21.04). In Windows, the WiFi card works just fine, but it doesn't work in Ubuntu.

lspci and lshw both recognize it.

I have tried disabling Windows' "fast boot" feature, as well as using version 21.04. I also apt upgraded linux-firmware, with no useful results. sudo dmesg | grep iwl shows a message like No suitable firmware found!.

Any help would be much appreciated. Thank you very much. I'm a total Linux noob, but I'm comfortable with the Unix shell.

Edit:

`ls -al /boot`

See https://askubuntu.com/questions/1352653/intel-ax201-wi-fi-6-is-not-working-on-ubuntu-21-04 — heynnema, Sep 18 '21 at 21:45
Hi @heynnema, thanks for your reply. I was trying to follow your instructions, but I got caught up on the “dkms build” step. It’s saying that “make” exited 2. I looked at the log file, and it looks like there are some “implicit function declaration of function “kzfree”” errors. Do I need to try with 21.04? — ajs256, Sep 18 '21 at 23:54
Sorry for not noticing that! I followed the steps there, but it’s still not working. Notably, backport-iwlwifi-dkms did install normally, and I see only kernel versions 5.11.0-34 and 5.11.0-16. I used the latter. — ajs256, Sep 19 '21 at 02:34
Edit your question and show me ls -al /boot and dkms status and modinfo iwlwifi. Select the pasted text and then click the {} icon to format the text. Start comments to me with @heynnema or I may miss them. — heynnema, Sep 19 '21 at 02:56
Thanks for the info. The modinfo command didn't show me what I needed to see. So show me the drv.c file where you added the line... and include about 10 lines above and 10 lines below the edit (21 lines total). Show me grep -i iwlwifi /var/log/syslog. Why did you dkms build on kernel -16 instead of -34? — heynnema, Sep 19 '21 at 03:28
And show me grep -i OBSOLETE_BY /usr/src/backport-iwlwifi-8613/dkms.conf — heynnema, Sep 19 '21 at 03:33
Why did you dkms build on kernel -16 instead of -34? - because that was the "other one" from the default, and I used that one since I didn't see -2x. Files forthcoming later. — ajs256, Sep 19 '21 at 03:49
I'm told that this won't work with the -16 kernel. Boot to the -34 kernel and do the dkms commands again, and then do dkms status again to make sure it got built/installed correctly on -34. Then reboot and retest. — heynnema, Sep 19 '21 at 03:54
It's not finding the AX201 firmware .ucode files. Install linux-firmware and add the firmware files from https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html with sudo cp. Then reboot. — heynnema, Sep 19 '21 at 12:53
I assume that you added the two comments, "// START AJS256 CHANGES" and "// END CHANGES" to drv.c. I'm not 100% sure that's the correct format, so I'd remove those lines. Then do the dkms commands again. Remember to start comments to me with @heynnema — heynnema, Sep 19 '21 at 12:57
YESSSSSSSSSSS!!!!!!!!! All I had to do was enroll the MOK encryption key after the reboot (for some reason, it wasn't automatic). Thank you so much for your help @heynnema! — ajs256, Sep 19 '21 at 16:55
Great news! After making the various mods, was it the Intel firmware that was the final missing piece? Please make a "it worked for me" comment, and upvote my answer on the other question. Thanks! — heynnema, Sep 19 '21 at 18:24
@heynnema I think the MOK was the problem. Yes, I am using the -34 kernel now. I don't have enough reputation to upvote or comment on your answer, but I would. — ajs256, Sep 19 '21 at 18:38
