How do I install Wifi Drivers for the Arduino Uno Wifi Rev 2?
Updated
macOS No drivers are needed for the Arduino UNO WiFi Rev2 on macOS.
Windows (tested on XP, 7, Vista and 10) At this point of this Getting Started guide you already have installed the drivers together with the Arduino Software (IDE) and the board will be recognized automatically.
Linux There is no need to install drivers for Ubuntu 10.0.4 and later, but make sure port 5353 is not being blocked by a firewall.
Users with Linux need to run this code in the terminal: ~/.arduino15/packages/arduino/hardware/megaavr/1.8.1/scripts/create_dfu_udev_rule
You need to be admin on the computer to do so.
