20.04 - Fix Wifi issue network unclaimed (AX201)

I don't have Wifi on my laptop (Dell, Linux Ubuntu 20.04 no dualboot) since I rebooted it. Before, I had no problem and I did not change anything. On the reboot, I had a blue screen talking about "MOK Management" and I choose to "Continue boot". Once on the OS, resolution has been changed and I lost Wifi options. I rebooted it again, resolution has came back to normal but still no Wifi. Oh and I can't connect though Ethernet either.

Here are some infos, sorry for the quality I had to take it myself with my phone : kernel 5.11, Wifi Intel AX201 https://ibb.co/N24wzrt

I saw a lot of answers about it but I can't make it works so if you can help me, it would be great.

EDIT :

Result of sudo modprobe iwlwifi && sudo dmesg | grep iwl :

modprobe: ERROR: ../libkmod/libkmod-module.c:838 kmod_module_insert_module() could not find module by name='iwlwifi'
modprobe: ERROR: could not insert 'iwlwifi': Unknown symbol in module, or unknown parameter (see dmesg)

EDIT 2 :

Empty result for sudo dmesg | grep iwl

Result for sudo dkms status : backport-iwlwifi, 8324: added

Result for modinfo iwlwifi | grep filename : modinfo: ERROR: Module iwlwifi not found.

Start by disabling Secure Boot in UEFI and troubleshoot from there.

@ChanganAuto I checked and disabled it already, did not resolve anything

Please edit your question to show the result of the terminal command: `sudo modprobe iwlwifi && sudo dmesg | grep iwl` Welcome to Ask Ubuntu.

Verrry interesting! May we now see: `sudo dmesg | grep iwl` and also: `sudo dkms status` and finally: `modinfo iwlwifi | grep filename`

@chili555 Done ! Hope it will help, because it does not give me any clue as a newbie :D

Please try: `sudo dkms remove backport-iwlwifi/8613 --all` Reboot and show us again: `modinfo iwlwifi | grep filename`

@chili555 The remove command show `Error! There are no instances of module: backport-iwlwifi 8613 located in the DKMS tree`. But the autocomplete show me a backport-iwlwifi/8324. Same message after reboot for the `modinfo` command

In our chat, we learned thet the package *linux-modules-extra* that provides the driver iwlwifi, among others, was not installed. We therefore undertook the same fix as the duplicate and all is working as expected.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
