Based on this
Install driver rtl8814au on ubuntu 18.04
I installed manually (make && make install) the driver when I had the kernel
$ uname -r
5.4.0-26-generic
Now, ubuntu 20.04 wants to install the new one:
linux-image-5.4.0-29-generic
I did it before (upgrade the system then, the kernel) and the driver stopped to work, even I installed thousand times, was impossible to up the driver which logical name is "wlx50c4ddcf488e".
The installation I made:
$ sudo apt install build-essential
$ sudo apt install bc
$ sudo apt install linux-headers-`uname -r`
$ sudo apt install git
$ git clone https://github.com/aircrack-ng/rtl8812au.git
$ cd rtl8812au
$ make && sudo make install
Does anyone has idea about what can I do? Now, I cannot upgrade my system without losing the wireless connection.
Thank a lot.
