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
Checking Network Connection
iw dev <interface> link
If connected to a network the output will show the details of the connection:
$ iw dev wlan0 link
Connected to 12:34:56:78:9a:bc (on wlan0) SSID: MyNetwork freq: 2437 RX: 32843 bytes (117 packets) TX: 1303 bytes (12 packets) signal: -44 dBm tx bitrate: 150.0 MBit/s MCS 7 40MHz short GI bss flags: short-preamble short-slot-time dtim period: 1 beacon int: 100
$ iw dev wlan0 link
Not connected.
Getting an IP Address (dhclient)
dhclient <interface>
Checking IP Address and Connectivity
Checking Interface Configuration/Connection (ifconfig)
$ ifconfig

Checking Internet Connection (ping)
$ ping google.com
