My laptop says "No WiFi adapter found" when I go to settings. Here is what lpsi returns:

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b852]

and lshw -C network:

WARNING: you should run this program as super-user.

I have checked that it is not hard-blocked in BIOS. I have tried both the rtw89 and rtw88 drivers and followed instructions for those to no avail. I also tried buying a wifi usb dongle, but cannot get that one to work with linux either.

I have a Lenovo yoga 6 13ALC7 and Ubuntu 22.04 LTS. Is there any way to get wifi on this computer?

Thank you in advance for any help!

User @Chilli just posted an alternate driver for your particular device. Reboot before you run the commands. The answer is here, just skip the first two commands (start with sudo apt update). Also, after you run sudo make install you may need to run sudo modprobe 8852be to load the driver.

sudo apt update

sudo apt install git bc

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

cd rtl8852be

make

sudo make install

sudo modprobe 8852be
