NetworkManager is the defacto network connection system for many linux distributions. NetworkManager supports mobile phone, wireless, and wired connections. NetworkManager is intended to make configuring, and connecting easy.

Installation

   Note

disable wicd, wpa_supplicant, net.ethX, & net.wlanX and dhcpcd prior to starting network manager.

root # emerge networkmanager
root # rc-update add NetworkManager
root # rc

Any users besides root will need to be added to the plugdev group to modify connections:

root # gpasswd -a $USER plugdev

   Note

If you're experiencing troubles, loosing connection after a 45-second timeout with NetworkManager and dhcpcd, switch the dhcp backend to dhclient (net-misc/dhcp).

Configuration

Gui

Gtk

   Note

Sessions for users may need ck-launch-session in .xinitrc to use nm-applet, or have sessions launched from a display manager.

root # emerge nm-applet

Kde

root # emerge plasma-nm

Console

   Note

As of 17:52, April 12, 2015 (UTC) nmtui's not suitable for wifi configurations because it will not save pass phrases.

root # nmtui

command line

To list visible access points:

root # nmcli dev wifi list
*  SSID                     MODE   CHAN  RATE       SIGNAL  BARS  SECURITY

*  connectedap              Infra  1     54 Mbit/s  52      ▂▄__  WPA1 WPA2

   Note

The following command will not work as long as you are in chroot environment. The reason for this is that addwifi will need dbus and rfkill to be set up. So don't forget to reboot!

root # addwifi -S wpa -K 'wifipassword' mywifinetwork

The addwifi command is used to configure and connect to a WPA/WPA2 Wi-Fi network connections. Network configuration entries are stored in /etc/NetworkManager/system-connections so that it will be remembered in the future.
