NetworkManager

NetworkManager is a program for connecting to internet. It is only needed for wireless connections.

Installation

Debian probably has NetworkManager pre-installed. A manual install can be done by executing the following command:

sudo apt install network-manager

It is recommended to use iwd as a backend for NetworkManager. Iwd is the modern replacement for wpa_supplicant.

Usage

NetworkManager provides a command line (CLI) tool to connect with the internet called nmcli (NetworkManager CLI). The graphical equivalent provided is nmtui (NetworkManager Terminal User Interface).

To list the available Wi-Fi networks execute:

nmcli device wifi list

To connect to a Wi-Fi network using nmcli execute:

nmcli device wifi connect <SSID> [password <password>]

• <SSID> is the name of the Wi-Fi network.
• <password> is the password of the Wi-Fi network.
