Save wifi networks and passwords to recover them after reinstall OS

Question

I want to change my linux distribution, how can I save all my known wifi networks and passwords so that I can restore them after installing a new OS.

I want to switch from PopOs with gnome to Manjaro with KDE

Answer 1

The WiFi passwords of saved networks can be acquired by running this command:

sudo grep psk= /etc/NetworkManager/system-connections/*

This will show you the list of the WiFi networks and their passwords.

On gnome, you may find the password of any connection by:

• Open Settings
• Click on WiFi
• On the WiFi access point (AP) name click on the small gear icon
• In the Security tab click "Show password" to view the saved password.
