Canonical does not make drivers for hardware. If they are not in the kernel, they aren't. If they aren't, then you have to install one. If it doesn't work, that's on the OEM's developers. The Linux kernel developers aren't going to do that for them. That's not their job.

It's no different in Windows. OEMs write drivers, not Microsoft. The OEMs have to go through flaming hoops to get their drivers into the Windows driver base. If they don't, the driver has to be installed. If the OEM botches the driver, it's on them. Microsoft doesn't lift a finger to make drivers work. That's not their job.

Purveyors of distros don't write drivers, so Ubuntu is not at fault here.

Just bear that in mind when asking for support. There are many things one can find with Canonical to complain about. But hardware drivers are not one of them.

If you want to use the driver you installed, do the following to disable wifi power management

Code:

echo "options 8723au rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8723au.conf

Then we should blacklist the kernel module so they don't conflict

Code:

echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

Reboot, if the wifi refuses to work using the 8723au you installed, you can load the kernel module with

Code:

sudo modprobe rtl8xxxu
