WPA Supplicant


Configuration

You can configure wpa_supplicant daemon by editing /etc/wpa_supplicant/wpa_supplicant.conf.

/etc/wpa_supplicant/wpa_supplicant.conf: wpa_supplicant daemon config
# provide control interface for wpa_cli and wpa_gui frontends
ctrl_interface=/run/wpa_supplicant

# allow wpa_cli and wpa_gui to update config
update_config=1

network={
	ssid="SSID"
	psk="passphrace"
}

network={
	ssid="SSID2"
	key_mgmt=NONE
}

Daemon

Start daemon with openrc.

# /etc/init.d/wpa_supplicant start

You can also add it to default runlevel.

# rc-update add wpa_supplicant default

The daemon can work independently or you can use wpa_cli and wpa_gui frontends. You can also alter configs with frontends.
