Arduino Uno board works but Arduino Uno + Wifi is not being detected When I connect my Arduino Uno board it instantly detects the board and shows it in the list. But when I connect my new Uno + Wifi board it doesn't detect it. I also manually selected Arduino Uno Wifi but it still gives me the message 

Error uploading check if the selected board is currently available

How can I fix this?

This is the one that's not working:

Arduino Uno + Wifi

While this one I got does work:

What you have there is a cheap Chinese clone. It uses the cheap CH340G USB chip instead of the proper ATMega16u2 that real Arduinos use.

Install the right drivers and it should start working.
