NetworkManager is a system network service that manages your network devices and connections and attempts to keep network connectivity active when available. It manages Ethernet, WiFi, mobile broadband (WWAN) and PPPoE devices while also providing VPN integration with a variety of different VPN services.
By default network management on Ubuntu Core is handled by systemd’s networkd and netplan. However, when NetworkManager is installed, it will take control of all networking devices in the system by creating a netplan configuration file in which it sets itself as the default network renderer.
What NetworkManager Offers
The upstream NetworkManager project offers a wide range of features and most, but not all of them, are available in the snap package at the moment.
Currently we provide support for the following high level features:
- WiFi connectivity
- WAN connectivity (together with ModemManager)
- Ethernet connectivity
- WiFi access point creation
- Shared connections
- VPN connections
