How to remove sleep mode macbook pro 2017 Mojave?

Question

macOS

the problem is such, even when connected to the power supply, when the screen is locked, when the screen goes blank, it feels like it falls into a dream, after turning it on it reconnects to the network, how to make it so that even when the screen goes blank, the network always worked or it still falls into a dream, in the settings everything seems to be fine.
I need the computer to work, and the application was always connected to the Internet, but it turns out that after the screen is locked, the network disappears and it turns out to be disconnected, and when I go back into it, it connects again
