I thought this might be useful information for any Miracast users:
I was wondering why my network data usage was showing WiFi being used almost 3 times more than Ethernet, although I use Ethernet exclusively having WiFi disconnected, using WiFi only when on the road which has not happened too often lately. Screenshot of Data Usage:
Checking the details I noticed that the process using most of WiFi was WUDFHost, Windows Driver Foundation User-mode Driver Framework Host Process:
Researching this a bit, I found out that me missing my native languages Finnish and Swedish in my expat life is the culprit, me streaming TV from Finland. Like in most laptops, I can only connect one external display to this one. To be able to watch my Finnish subscription IPTV on third display, I have a Microsoft Wireless Display Adapter connected to a Philips smart TV (smart but too old to have its own Miracast support).
This works well. I use laptop's built-in display and an external display connected with HDMI for my work and browsing, having almost always the Miracast connected TV as third display showing Finnish TV stream on Chrome, a browser I don't like but which works best with this service.
Checking Task Manager I can see that when Miracast is used, WUDFHost uses constantly 10 to 20 Mbps for upload, to cast the stream:
It has four processes open as can be seen in Task Manager but luckily it is using relatively little resources:
My point:
If you are using Miracast, do not wonder when your WiFi usage looks weird. Also, if you have some bandwidth limits from your ISP, there's no reason to be worried; the WiFi usage shown and caused by Miracast is internal having none whatsoever effect in your bandwidth usage and ISP's bill.
