Bringing up Wireless Interface
The wireless interface (most commonly wlan0) can be brought up with:
ifconfig <interface> up
Wireless Bringup on Boot
The wireless interface bring-up behaviour can be configured within /etc/network/interfaces.d.
Connecting to Networks (wpa_supplicant)
A network connection can be established by starting the wpa_supplicant daemon. The WPA supplicant requires a configuration file with a list of network configurations to use for connection.
$ wpa_supplicant -B -Dnl80211 -iwlan1 -c/etc/wpa_supplicant.conf
Successfully initialized wpa_supplicant

iw dev <interface> link
If connected to a network the output will show the details of the connection:
$ iw dev wlan0 link
