Windows 10: WiFi Download Speeds Stall

There is an issue with Receive Segment Coalescing (RSC) on Windows 10 that causes download speeds to stall while connected via WiFi.

Steps to disable Rsc using Microsoft’s automated tool:

    1) Download the “.diagcab” file located here:

    2) Run it, and let it see if it can determine the problem and fix it.

    3) Re-test your wireless internet connection.


Once the above is done the problem goes away.
