The solution is to install a wireless driver. Connect your laptop to the internet using e.g. a phone by a USB cable, then tun in a terminal:

sudo apt update
sudo apt install git dkms
git clone https://github.com/lwfinger/rtw88.git
sudo dkms add ./rtw88
sudo dkms install rtlwifi-new/0.6

Then reboot and disable Secure Boot in BIOS.
