No Wifi before login?

I’m running ubuntu 18.04.3 on VIM3. There seems to be some problems for VIM3.

On of the key issues is: I’ve got to login khadas VIM3 before Wifi is enabled. This means: I cannot ssh into khadas VIM3 remotely without a keyboard/mouse connected to khadas VIM3 for login purpose ONLY.

That is clearly ridiculous. And this seems to be an issue for VIM1 and VIM2 for a long time. Please refer to

Do you have any solutions to this issue ALREADY?
