ERROR:Problem starting the wireless device

Hi, it's me again.
Well, I update Calibre to version 3.5.0, and now, everytime I start or restart the program, I see this message:


ERROR: Problem starting the wireless device: The wireless device driver had problems starting. It said "attaching port to broadcast socket failed. This is not fatal."







However, I can connect Moon+ Reader Pro to Calibre, and when I test the server, all is ok.

Any idea?
