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
