I just bought a asus tuf gaming a15 and wanted to install ubuntu 18.04 (not 20.04 because some programs like tensorrt is not yet supported there). I used a bootable usb to install and after installing i could not boot because of this issue Can't install Ubuntu 20.04 on ASUS Tuf a15 (ACPI?) so following the recommended answers (GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset") i manage to boot. But then i realised that while wifi seems to working it cannot find any networks around.
