Installation instruction
Requirements
You will need to install "make", "gcc", "kernel headers", "kernel build essentials", and "git".
For Ubuntu: You can install them with the following command
sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git
For Fedora: You can install them with the following command
sudo dnf install kernel-headers kernel-devel
sudo dnf group install "C Development Tools and Libraries"
For openSUSE: Install necessary headers with
sudo zypper install make gcc kernel-devel kernel-default-devel git libopenssl-devel
For Arch: Install the necessary kernel headers and base-devel,
If any of the packages above are not found check how your distro installs them.
Requirements

bc
gcc

git
Installation
For all distros:
git clone https://github.com/lwfinger/rtw8852be.git
cd rtw8852be
make
sudo make install
Installation with module signing for SecureBoot
For all distros:
git clone git://github.com/lwfinger/rtw8852be.git
cd rtw8852be
make
sudo make sign-install
You will be promted a password, please keep it in mind and use it in next steps. Reboot to activate the new installed module. In the MOK managerment screen:
- Select "Enroll key" and enroll the key created by above sign-install step
- When promted, enter the password you entered when create sign key.
- If you enter wrong password, your computer won't not bebootable. In this case, use the BOOT menu from your BIOS, to boot into your OS then do below steps:
sudo mokutil --reset
Restart your computer Use BOOT menu from BIOS to boot into your OS In the MOK managerment screen, select reset MOK list Reboot then retry from the step make sign-install
How to disable/enable a Kernel module
sudo modprobe -rv 8852be #This unloads the module
sudo modprobe -v 8852be #This loads the module
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>
This driver has many options as you will see with 'modinfo 8852be'. Thus far, no one has needed to use any of them.
When your kernel changes, then you need to do the following:
cd ~/rtw8852be
git pull
make
sudo make install
Remember, this MUST be done whenever you get a new kernel - no exceptions.
Installation with module signing for SecureBoot

git clone git://github.com/lwfinger/rtw8852be.git
cd rtw8852be

sudo make sign-install

If you enter wrong password, your computer won't not rebootable. In this case, use the BOOT menu from your BIOS, to boot into your OS then do below steps:
sudo mokutil --reset
Restart your computer Use BOOT menu from BIOS to boot into your OS In the MOK managerment screen, select reset MOK list Reboot then retry from the step make sign-install
These drivers will not build for kernels older than 4.14. 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.
DKMS packaging for ubuntu/debian
DKMS on debian/ubuntu simplifies the secure-boot issues, signing is taken care of through the same mechanisms as nVidia and drivers. You won't need special reboot and MOK registration.
Additionally DKMS ensures new kernel installations will automatically rebuild the driver, so you can accept normal kernel updates.
Prerequisites:
A few packages are required to build the debs from source:
sudo apt install dkms debhelper dh-modaliases
Build and installation
# If you've already built as above clean up your workspace or check one out specially (otherwise some temp files can end up in your package)
git clean -xfd
dpkg-buildpackage -us -uc
sudo apt install ../rtw8852be-dkms_1.0.0_all.deb
That should install the package, and build the module for your
currently active kernel. You should then be able to modprobe
as
above.
