11

I have a dual boot with Ubuntu 22.04 and Windows 11 freshly installed, but my Wi-Fi is not working. It states that "No Wi-Fi Adapter Found". The card is a Realtek RTL8852BE WiFi 6 802.11ax.

The result of terminal command lspci -nnk | grep 0280 -A3 is:

01:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b852]
    DeviceName: Realtek Wireless LAN + BT
    Subsystem: Hewlett-Packard Company Device [103c:88e3]
02:00.0 Non-Volatile memory controller [0108]: Micron Technology Inc Device [1344:5404] (rev 03)

My laptop has an AMD Ryzen 7 5825U processor and AMD Radeon graphics. Any help will be greatly appreciated.

EDIT: Please remove the incorrect driver package:

sudo add-apt-repository -r ppa:kelebek333/kablosuz 
sudo apt purge rtw89-dkms 
sudo apt update
sudo apt install git bc build-essential
git clone https://github.com/HRex39/rtl8852be.git
cd rtl8852be
make

Several possibly harmless warnings will appear.

sudo make install

Reboot. You will probably need to disable secure boot.

After each kernel update, you must recompile:

cd rtl8852be
make clean
git pull
make
sudo make install

This solved my WIFI:

git clone https://github.com/HRex39/rtl8852be.git

and Bluetooth worked after:

git clone https://github.com/HRex39/rtl8852be_bt.git.

Thanks

#Turn off your Security Boot in BIOS

git clone https://github.com/HRex39/rtl8852be.git
cd rtl8852be
make -j8
sudo make install
sudo modprobe 8852be

After some tinkering, I got this to work on a new Lenovo ThinkBook G2 (took longer than necessary because I didn't check the README). If your kernel version is 5.18 (check with uname -r) or above, you need to use:

git clone https://github.com/HRex39/rtl8852be.git -b dev

to get the correct version. Other steps are the same as in chili555's answer. Make sure Secure Boot is disabled if you run into problems.

Hope my addition helps someone, and thank you chili555!
