NetworkManager is a program that provides automatic detection and configuration for systems to connect to networks.

Installation

# apk add networkmanager


NetworkManager comes with a command line interface and a curses-based interface, nmcli and nmtui respectively or you can use a additional gui interface:


After installation start NetworkManager:

# rc-service networkmanager start


Wireless networks

wpa_supplicant backend

Note: wpa_supplicant configuration might not be required, if it isnt it may be a good idea to have it setup just as a fallback


Now open /etc/NetworkManager/NetworkManager.conf in a text editor and change it to something like this:

Contents of /etc/NetworkManager/NetworkManager.conf

[main] dhcp=internal plugins=ifupdown,keyfile [ifupdown] managed=true [device] wifi.scan-rand-mac-address=yes wifi.backend=wpa_supplicant
Note: if these options dont work on your system you can change them as necessary


Now you need to stop conflicting services:

# rc-service networking stop

and

# rc-service wpa_supplicant stop


Now restart NetworkManager:

# rc-service networkmanager restart


Now connect to a network using one of the interfaces mentioned in Installation


If that connects and stays connected with no issues enable the networkmanager service and disable the networking and wpa_supplicant boot services:

# rc-update add networkmanager

# rc-update del networking boot

# rc-update del wpa_supplicant boot


iwd backend

NetworkManager supports wireless networks through iwd. After installation, enable the server and restart NetworkManager:

rc-service iwd start
rc-service networkmanager restart

To use iwd though, you've have to edit NetworkManager's configuration because it still defaults to wpa_supplicant instead. Add the following to /etc/NetworkManager/NetworkManager.conf:

[device]
wifi.backend=iwd


VPN support

Since version 1.16, NetworkManager has support for Wireguard[1].

Support for other VPN types is provided by plugins. They are provided in the following packages:
