As soon as I connect my Surface 3 tablet to Plugable USB 3.0 docking station (UD-3900 Rev B2) the tablet loses its Wi-Fi connection. Immediately after I remove the plug or power down the docking station, Wi-Fi connection restores itself. Please help!
USB 3.0 devices like our docking station can emit 2.4GHz wireless interference. If possible try moving the dock further away, or to a different side of the tablet.
If your wireless router supports 5GHz vs 2.4GHz, I recommend switching to that as then the dock cannot interfere with the WiFi as they will be working on different frequencies.
Intel has a technical whitepaper on the interference behavior:
