Adding Static Wi-Fi IP address on Ubuntu/Debian and derivaties

• Begin by Hex encoding your wifi details

sudo wpa_passphrase "Your Wifi Network SSID"  "Your Wifi WPA/WPA2 password"

Output:

network={
	ssid="Your Wifi Network SSID"
	#psk="Your Wifi WPA/WPA2 password"
	psk=aeddac6f23c5c5c21d6ef9909837d3f93cf574b6e56f13a23328b1f001f7f53c
}

• Edit the interfaces configuration file

sudo vi /etc/network/interfaces

• Add the following to the end of the file or edit the file accordingly if you already have auto wlan0 & iface wlan0 sections
• Adapt your IPs according to your network

# The wifi network interface
auto wlan0
iface wlan0 inet static
    address 192.168.0.2
    netmask 255.255.255.0
    network 192.168.0.0
    broadcast 192.168.0.255
    gateway 192.168.0.1
    dns-nameservers 192.168.0.1, 192.168.0.2, 8.8.8.8
    wpa-ssid "Your Wifi Network SSID"
    wpa-psk "aeddac6f23c5c5c21d6ef9909837d3f93cf574b6e56f13a23328b1f001f7f53c"

• For DHCP

# The wifi network interface
auto wlan0
iface wlan0 inet dhcp
    wpa-ssid "Your Wifi Network SSID"
    wpa-psk "aeddac6f23c5c5c21d6ef9909837d3f93cf574b6e56f13a23328b1f001f7f53c"

• After reboot your wifi network should be active and connected with a fixed IP before user login.
