GitHub - lwfinger/rtw89: Driver for Realtek 8852AE, an 802.11ax device

You will need to install "make", "gcc", "kernel headers", "kernel build essentials", and "git". You can install them with the following command, on Ubuntu:

sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git

If any of the packages above are not found check if your distro installs them like that.

Installation

For all distros:

git clone https://github.com/lwfinger/rtw89.git -b v5
cd rtw89
make
sudo make install
How to disable/enable a Kernel module
sudo modprobe -r rtw89pci         #This unloads the module
sudo modprobe rtw89pci            #This loads the module
Problem with recovery after sleep or hibernation

Some BIOSs have trouble changing power state from D3hot to D0. If you have this problem, then

sudo cp suspend_rtw89 /usr/lib/systemd/system-sleep/.

That script will unload the driver before sleep or hibernation, and reload it following resumption.

Option configuration

If it turns out that your system needs one of the configuration options, then do the following:

sudo nano /etc/modprobe.d/<dev_name>.conf

There, enter the line below:

options <device_name> <<driver_option_name>>=<value>

The available options for rtw89pci are disable_clkreq, disable_aspm, and disable_aspm The available options for rtw89core are debug_mask, and disable_ps_mode

Normally, none of these will be needed.

When your kernel changes, then you need to do the following:

cd ~/rtw89
git pull
make
sudo make install

Remember, this MUST be done whenever you get a new kernel - no exceptions.

These drivers will not build for kernels older than 5.4. If you must use an older kernel, submit a GitHub issue with a listing of the build errors. Without the errors, the issue will be ignored. I am not a mind reader.

When you have problems where the driver builds and loads correctly, but fails to work, a GitHub issue is NOT the best place to report it. I have no idea of the internal workings of any of the chips, and the Realtek engineers who do will not read these issues. To reach them, send E-mail to linux-wireless@vger.kernel.org. Include a detailed description of any messages in the kernel logs and any steps that you have talenovo wifi
