How to enable wifi in Ubuntu before user authorization?

Question

linux

Turned on the computer.
Went to download ubuntu.
A login screen appears asking you to enter a password.
At this point, until the user enters a password, the computer does not connect to a known wifi network.
When I entered my password and logged in, the computer immediately connected to the Internet via wifi.
I need the computer to connect to wifi before entering the password. So that I can remotely connect to the computer and log in.
How to do it?
Thank you!

Answer 1

In the connection settings, mark make avaibled to other users. If it does not help, then demolish NetworkManager and install wicd. If it does not help, then demolish everything and directly configure wpa_supplicant.

Answer 2

install ubuntu -server and don't bother with the settings
in the finished system sudo apt-get install ubuntu-server
