WiFi

Based on RaspberryPi.org Configuration Docs

Installation

Connect the Pi (via LAN), and SSH in.

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="your wifi network SSID"
    psk="your wifi network password"
}

Tip: You can grab the connected network's password on MacOS under the System section of Keychain Access.

Finally, reboot and unplug the LAN cable:

sudo reboot

Tip: Once restarted, you'll need the Pi's new IP address to SSH back in. You can find this using the following:

arp -a
