No Wifi after fresh installation of ubuntu 22.04 intel Wi-Fi 6 AX200

Question

After a fresh installation of Ubuntu 22.04 I'm not able to use my wifi. The card is the intel Wi-Fi 6 AX200.

During installation I had no trouble using the card downloading updates. After the installation I can't use wifi.

I use a dual boot with Windows 11.

I tried to fix it with sudo apt install backport-iwlwifi-dkms. After rebooting there was no change.

After that I installed the official firmware from Intel for this card by unzipping the ucode file and transferred it to /lib/firmware. After a reboot it worked.

a few hours later I started into win11 where I got a prompt regarding some firmware files that where tried to install. After googling the name it was about the mentioned network card (before I never saw this and didn't have issues in win11 with the card). After that I just forced closing the window and never saw this dialog again (I didn't know what to do and I also don't know if there is a correlation, but I wanted to mentioned it)

After my next boot to Ubuntu the network drivers where gone in terms of I couldn't use wifi so I reproduced the initial fix, but I had no luck.

You didn't indicate which Ubuntu 22.04 LTS product/ISO you actually used, as some ISOs can boot and use older kernels in the live session to what you'll use after updates & first boot. Is this Ubuntu 22.04 LTS Server? Ubuntu 22.04 LTS Desktop? and which ISO (22.04? 22.04.1? 22.04.2? 22.04.3 etc). 22.04 media is available using the 5.15, 5.19 & 6.2 kernels, and post-install it will use 5.15 or 6.2 now ; but you didn't specify which you used. — guiverc, Sep 02 '23 at 12:52

@chili555 thx this hint solved my problem. The solution was to disable fast startup in win11 — jimboextended, Sep 02 '23 at 16:06

Allow me to share how I fixed this. Regardless of the root cause, [ 3.747829] iwlwifi: probe of 0000:07:00.0 failed with error -110 generally means the driver failed to init. To get a driver that works on your system

1.) $ sudo dmesg | grep iwlwifi Will show you which driver is attempted to be loaded.

Something like [ 3.109344] iwlwifi 0000:00:14.3: loaded firmware version 68.01d30b0c.0 QuZ-a0-hr-b0-71.ucode op_mode iwlmvm

2.) note the driver version number (in the above case it's 71)

3.) now in the directory /lib/firmware search (using find or fd or whatever) for all files that start with iwlwifi-QuZ-a0-hr-b0-*. Your system keeps many versions of the driver designed for your wifi card, probably indicated by this portion QuZ-a0-hr-b0-.

4.) Progressively try the previous versions of your driver. For example if the driver that you see failing to load in dmesg is QuZ-a0-hr-b0-71, then do $ cp iwlwifi-QuZ-a0-hr-b0-71 backup_iwlwifi-QuZ-a0-hr-b0-71
and either $ sudo modprobe -r iwlwifi; $ sudo modprobe iwlwifi or reboot to make the new driver take effect.

You can view what driver loads from that dmesg command: $ sudo dmesg | grep iwlwifi

and keep doing this until you reach a iwlwifi-QuZ-a0-hr-b0- that works for you. In my case I had to eliminate all of these:

[    3.096222] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-77.ucode failed with error -2
[    3.096379] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-76.ucode failed with error -2
[    3.096454] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-75.ucode failed with error -2
[    3.096935] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-74.ucode failed with error -2
[    3.096970] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-73.ucode failed with error -2
[    3.097172] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-72.ucode failed with error -2
[    3.097212] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-71.ucode failed with error -2
[    3.097458] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-70.ucode failed with error -2
[    3.097916] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-69.ucode failed with error -2

That's my dmesg log showing that my kernal is looking for these drivers that I've deleted (I've recommended above that you rename them, but it has the same effect). Until it finally finds one that works:

[    3.109344] iwlwifi 0000:00:14.3: loaded firmware version 68.01d30b0c.0 QuZ-a0-hr-b0-68.ucode op_mode iwlmvm

So you can see I had to go back quite a few versions in order to reach one that works.

(I discovered this by booting from a live usb with the same major version as my ubuntu system with the broken wifi and noted what driver was working from dmesg)

It saved me having to do anything drastic

"note the driver version number" Those are firmware versions, not driver versions. Nonetheless, I like this approach and I'm glad it worked. — chili555, Feb 10 '24 at 20:50
