[Ubuntu18.04 solves the ax201 wireless network card driver installation for Bluetooth wifi]

1 Introduction

The desktop is installed with a dual-system win11+Ubuntu18.04 system, and it is found that there is no wireless network card and Bluetooth. After consulting the information, it is found that the ax201 network card driver has not been integrated in Ubuntu because the network card has not been used for a long time. You need to install the ax201 network card driver yourself. First make sure whether the kernels version is greater than 5.2, then go to the official website to download the driver, and restart the computer!

2. Update the linux kernel

First check the kernel version

uname -r

Mine is 5.4 enough and does not need to update the kernel. The ax201 network card driver needs version 5.2 or above. Try to use the new kernel version.
