Arduino Yun REV2 - Couldn't find a Board on the selected port.

I got Arduino Yun REV2. I have a connection via WiFi and Ethernet.
I can ping IP Address WLAN0 and I can ping IP Address ETH1. I can open the webrowser with http://192.168.4.19/luci/webpanel/homepage

I can login.

The problem is that the Port is not active. This is a very common problem for this device.
I can choose from Board: Arduino Yun

If I wanna upload a code I see the below issue:

Couldn't find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board's reset button after initiating the upload.

Is it a proper way to upload code via WiFi?
