Connecting to new wifi network

[fryguy]

Tomorrow i will be moving my completed mirror to another location and therefor to a new wifi network. How do i stop the mirror from auto booting in order to establish a new connection? Using a raspberry pi 3. Thank you…

You Don,t have to quit

But if you would like that: npm stop.
