Connect Raspberry Pi to Wifi

It is fairly self explanatory to do it through the UI if there is one but to do it through the terminal all you have to do is :

• sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
• # Ensure it looks like

• country=GB
  ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
  update_config=1
  
  network={
      ssid="Errigal_WiFi"
      psk="PASSWORD"
  }

• save and exit
• Reboot and it should connect
• If having issues ensure your
• sudo nano /etc/network/interfaces
• looks like

• # interfaces(5) file used by ifup(8) and ifdown(8)
  
  # Please note that this file is written to be used with dhcpcd
  # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
  
  # Include files from /etc/network/interfaces.d:
  source-directory /etc/network/interfaces.d
