Enabling and Configuring NetworkManager

# NetworkManager {#sec-networkmanager} To facilitate network configuration, some desktop environments use NetworkManager. You can enable NetworkManager by setting: ```nix { networking.networkmanager.enable = true; } ``` some desktop managers (e.g., GNOME) enable NetworkManager automatically for you. All users that should have permission to change network settings must belong to the `networkmanager` group: ```nix { users.users.alice.extraGroups = [ "networkmanager" ]; } ``` NetworkManager is controlled using either `nmcli` or `nmtui` (curses-based terminal user interface). See their manual pages for details on their usage. Some desktop environments (GNOME, KDE) have their own configuration tools for NetworkManager. On XFCE, there is no configuration tool for NetworkManager by default: by enabling [](#opt-programs.nm-applet.enable), the graphical applet will be installed and will launch automatically when the graphical session is started. ::: {.note} `networking.networkmanager` and `networking.wireless` (WPA Supplicant) can be used together if desired. To do this you need to instruct NetworkManager to ignore those interfaces like: ```nix { networking.networkmanager.unmanaged = [ "*" "except:type:wwan" "except:type:gsm" ]; } ``` Refer to the option description for the exact syntax and references to external documentation. :::

NetworkManager can be enabled in the NixOS configuration to facilitate network configuration, particularly in desktop environments like GNOME. Users who need to modify network settings must be added to the 'networkmanager' group. NetworkManager can be controlled via command-line tools like 'nmcli' and 'nmtui', or through graphical interfaces provided by some desktop environments. It's also possible to use NetworkManager in conjunction with WPA Supplicant, by instructing NetworkManager to ignore specific interfaces.
