Intel Wireless Adapter suddenly not working - Ubuntu 20.04.3

cn flag

I have a Intel Corporation Wi-Fi 6 AX201 wifi adapter that is suddenly not working after a reboot. None of the existing askubuntu solutions help me with my issue.

I have found an error code in the logs that I would like to diagnose:

Does anyone know how to solve this?

Search for "AX201" here on AU and you'll find your answer.

Is this a dual-boot with Windows? Is Fast Boot turned off? https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled
cn flag
This is not dual boot. Fast boot is also turned off. Unfortunately looking up AX201 on AU hasn't helped me so far.

Please try upgrading to kernel version 5.15: https://askubuntu.com/questions/1377110/intel-ax201-wi-fi-6-and-ethernet-wont-work-ubuntu-20-04-and-21-10
cn flag
I updated to 5.15 but unfortunately still get `[ 7.834573] iwlwifi 0000:00:14.3: Failed to run INIT ucode: -110`. It does seem to try initialising twice now though with `retry init count 2`

Does it still load the -63 version of the firmware? `sudo dmesg | grep firm`
cn flag
Yes it does - `[ 7.294605] iwlwifi 0000:00:14.3: Loaded firmware version: 63.c04f3485.0 QuZ-a0-hr-b0-63.ucode `

The official Ubuntu package linux-firmware for 22.04, a testing release, also contains firmware versions -66, -67 and -68. Let's install them and see if the wireless now works.

Please open a terminal and do:

cd /usr/lib/firmware
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-66.ucode
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-67.ucode
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-68.ucode

Also, on the chance that the current firmware version -63 is somehow corrupted, let's install a fresh copy:

sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-63.ucode

Reboot and tell us if there is any improvement.

That fixed it. Thank you so much!

I stuggled with this and tried all the suggestions ... then as soon as I did this it and rebooted it worked!

Edit : /etc/default/grub

From : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"

Run: sudo update-grub

Reboot =)

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.
