SETUP PI ZERO WIFI

https://desertbot.io/blog/setup-pi-zero-wifi

****NOTE:

Raspberry Pi Zero: The original model Raspberry Pi Zero

and the newer version 1.3 with the camera connector

<DO NOT HAVE> any build in networking capability.

No Ethernet, no WiFi, and only a single micro USB OTG data port

(the outer port is power only).

OLD Pi Zero, Connect over WiFi

Plug your WiFi Adapter into the USB OTG cable and

plug the other end into the data / peripheral port

on your Pi Zero (see picture above).

Setting WiFi up via the command line
Using raspi-config
The quickest way to enable wireless networking is
to use the command line raspi-config tool.
sudo raspi-config

or....Adding the network details to the Raspberry Pi
Open the wpa-supplicant configuration file in nano:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
Go to the bottom of the file and add the following:

network={
ssid="testing"
psk="testingPassword"
}

Getting WiFi network details
To scan for WiFi networks, use the
command sudo iwlist wlan0 scan.
This will list all available WiFi networks,
along with other useful information. Look out for:
'ESSID:"testing"' is the name of the WiFi network.
