Hi there, so I have a Surface Pro 4 (Base Model Core M) and ordered the Microsoft Wireless Display Adapter along with it. I installed it all at home and the surface Pro had no problem whatsoever connecting to the display Adapter on the back of my TV. I brought it to work, plugged in the USB to Ethernet dongle (also the one from Microsoft) and tried to establish a connection to the Wireless display Adapter 2 Meters away in plain sight. The SP does see the Adapter, the adapter says "connecting" but the connection shaky at best if it comes to live at all. We are talking about 90%ish fail rate here. This has been going on for 2 days and it left me scratching my head. So I tried it at work without the USB-Ethernet dongle and things got much better. I had only one failed attempt. With an active connection I plugged in a USB3 Thumb drive and my Miracast connection froze almost instantly. Both SP4 and wireless display adapter have the newest software installed (unless there was a firmware update for the SP, which didn't come with the Windows Update). I begged our admin and got a WiFi AP but I still need the USB Port from time to time. So what do you think? Anyone with similar experiences? Any advice?
