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

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
