NetworkManager
NetworkManager - short NM - is a program to automatically detect and connect to networks by providing options for various configuration. It is used to set up Wi-Fi.
Setup
NetworkManager can be installed with the networkmanager package on most linux
distributions which provides daemon aswell as nmcli a command line interface
and nmtui a terminal user interface for
configuration.
Additionally nm-connection-editor can be installed for a graphical user
interface.
Usage
After installation networkmanager.service has to be enabled by the used
init-system (for example
systemD).
OpenVPN Integration
NetworkManager needs a plugin to work with openvpn configurations.
This plugin can be installed with the networkmanager-openvpn package.
OpenVPNs .ovpn files can then be imported by running
nmcli connection import type openvpn file <openvpn-file>.
Afterwards they can be modified accordingly.
Prioritize Connections
Connections can be prioritized making NetworkManager chose specific ones over others.
This can be done using nm-connection-editor.
Select the connection and navigate to General.
Then set the priority under Connect automaticcally with priority where 0 is the highest
priority, 1 being the next highest and so on.
Troubleshooting
This section focusses on the troubleshooting of situations where the system does not connect correctly.
Restarting and Reenabling Wi-Fi
A useful chain of commands is the following. It will restart the SystemD service and enable the Wi-Fi device.
systemctl restart NetworkManager
nmcli radio wifi on
If the error still persists afterwards it may be useful to also restart WPA Supplicant as explained in the corresponding section of its entry.
