Updating and installing WLAN tools

apt install wpasupplicant

Connect to WPA

Example content of /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source /etc/network/interfaces.d/*
auto wlan0
iface wlan0 inet dhcp
        wpa-key-mgmt WPA-PSK
        wpa-group TKIP CCMP
        wpa-ssid "MYSSID"
        wpa-psk "MYPASSCODE"

Remember: To secure file

chmod 600 /etc/network/interfaces

Connect to WPA2 Enterprise

/etc/wpa_supplicant/acme.conf

## Connect to a WPA2 Enterprise network using this command:
## wpa_supplicant -B -i wlan0 -c /etc/acme.conf
## Then run dhclient wlan0 to get an IP Address
network={
scan_ssid=1
eap=PEAP
ssid="MYSSID"
key_mgmt=WPA-EAP
identity="MYNAME"
password="MYPASSCODE"
phase1="peaplabel=0"
phase2="auth=MSCHAPV2"
}
