After a fresh install of Ubuntu on my new Lenovo Legion Y9000P 2022，I'm unable to use Wi-Fi or Bluetooth，or even the touch tablet of the PC. My Wi-Fi model is Intel Wi-Fi 6E AX211 160MHZ.

Can anyone help me? I'll appreciate you so much!

I have exact same wifi module on my laptop and solved this problem by installing the latest dkms backport-iwlwifi-dkms_9858-0ubuntu2_all.deb downloaded from https://launchpad.net/ubuntu/+source/backport-iwlwifi-dkms

check my answer here No hope for AX211 wifi working on ubuntu 20.04?

Simply

$ sudo dpkg -i backport-iwlwifi-dkms_9858-0ubuntu2_all.deb

and reboot.

I'm running Ubuntu 20.04.4 LTS, and what worked for me was to just update the Linux kernel to version 5.15 from version 5.13. Note: I am assuming that when installing Ubuntu, you installed the third-party software that includes WiFi drivers.

There are two ways to do this:

  1. If you have internet access (via an Ethernet to USB adapter for example), just run sudo apt-get upgrade linux-generic-hwe-20.04 followed by sudo reboot. To check that version 5.15 was installed, run apt list linux-generic-hwe* and you should see linux-generic-hwe-20.04/focal-updates,focal-security,now 5.15.0.46.49~20.04.16 amd64 [installed].
  2. If, like me, you do not have internet access, then you will need to install the latest version of the linux-generic-hwe-20.04 package manually. In my case, I had another laptop that had internet access, so I used that laptop to download the package and its dependencies, put them on a USB, and then moved them to the laptop that does not have internet access.

To do this, first go to this page. You will see the following dependencies:

linux-headers-generic-hwe-20.04 (= 5.15.0.46.49~20.04.16) [amd64]
    Generic Linux kernel headers 
linux-headers-generic-hwe-20.04 (= 5.4.0.26.32) [not amd64]
linux-image-generic-hwe-20.04 (= 5.15.0.46.49~20.04.16) [amd64]
    Generic Linux kernel image 
linux-image-generic-hwe-20.04 (= 5.4.0.26.32) [not amd64]

Before installing the package, you will need to install these dependencies first by clicking on their links. In my case, I installed the dependencies that had the label [amd64] next to them, since my laptop runs a 64-bit architecture. Unfortunately, these dependencies have their own dependencies, so you will have to click on each one and then download the corresponding .deb file. In total there were 7 .deb files that I had to download, so this does not take too much time. To download each package, click on the amd64 link under the Download <package name> title. Then, click on the link security.ubuntu.com/ubuntu. Once all packages are downloaded, put them all into a folder, and then put this folder onto a USB.

Finally, connect the USB to the laptop with no internet access, move the folder containing the packages to the desktop, cd into this folder, and then run sudo dpkg -i *.deb. You will get an error that the linux-generic-hwe-20.04 package could not be installed, but that is OK. Just run sudo reboot, and once logged in again, check that you have version 5.15 of the linux kernel by running uname -r. You should see 5.15.0-46-generic. Your WiFi should now be working.

I faced similar problems with the following setup:
+CPU: Intel core i7 13700H
+GPU: Nvidia GeForce GTX 1650
+Bluetooth-wireless: Gigabit Lan & Wireless intel @ Wi-Fi 6E AX211

The solution was to update Ubuntu to version 23.04, which also included the latest kernel. Despite trying multiple solutions and reading through numerous posts, I couldn't find any effective remedies. In my case, I also struggled with Nvidia drivers and issues related to suspend/resume functionality. If you're dealing with similar headaches, opting to install version 23.04 might just be the comprehensive solution you need. Choose "Third Party" options during the Ubuntu installation, and everything will work correctly after rebooting.

Follow these steps and you will make it:

Change your apt source to Main server in 'Software & Update' application. Then run

sudo apt -y update && sudo apt -y upgrade
sudo apt install bcmwl-kernel-source

Check the printed log for version number, such as:

update-initramfs: Generating /boot/initrd.img-5.15.0-106-generic

Then install 'Synaptic Package Manager' aplication:

sudo apt-get install synaptic

Open it, search for 'iwlwific' and select the one correspondding with the kernel version, for example "iwlwifi-5.15.0-106-generic". unselect others, then press 'Apply', wait until done

reboot

I have a ROG Zerphyrus G16 laptop and the wifi adapter (Intel(r) Wi-Fi 6E AX211 160 MHz) was not being recognized. After connecting through an Ethernet port and trying a million different tutorials that didn't work. I downloaded "linux-firmware-a19bb447e57a0caa2bcc1ddbda0476c1df2e098a.tar.gz" from this website below:

https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/commit/?h=for-upstream&id=a19bb447e57a0caa2bcc1ddbda0476c1df2e098a

Then after extracting into Downloads and from within the download directory I ran

$ sudo cp ./* /lib/firmware/

and rebooted and now Wi-Fi is working.

Maybe not tottaly related to Your problem, I'll share my story. I've bought NUC12WSHi5 with Intel Wi-Fi 6E AX211(Gig+)-removable. Installed Ubuntu 24.04.2 LTS Intel Wi-Fi 6E AX211(Gig+) works perfect on all frequencies (2,4 and 5GHz) when WLAN and Bluetooth are enabled in BIOS settings (if I disable BT in BIOS it get a bit buggy). Problem with connectivity arises when I connected a small USB (5V, 20mA, 0,1W) light into NUC, as NUC is always in the dark mounted behind monitor. If I disconnect the light, WIFI works. Not sure why this happens and I couldn't find a log mentioning this.. Maybe someone knows why and shed some light on this matter...much appreciated.
