Game streaming from Xbox One to Win 10 PC not working

By "not working", I mean horribly laggy, constantly pixelating and complaining of "network connection problems". The Xbox App reports a very poor and inconsistent network connection (averages 3Mb/s, but it's up and down between 0 and 6).

My network uses powerline adapters by the way.

I could accept this, except everything else works fine over the same network connection (streaming from my NAS, streaming from my gaming PC using Steam).

To be clear: Steam works flawlessly streaming games over the exact same cables and powerline adapters to the exact same PC in my living room.

The only thing that doesn't work well over that connection is Xbox game streaming. (Even Xbox game downloads are super quick - not the best measure of network connectivity, but quick, smooth downloads, and seemingly none of the up and down performance issues
that Xbox game streaming suffers.)

Any ideas?

My Win 10 PCs are up to date, cables all good, etc.

Xbox app streaming not (any longer) supports two controllers ?

I am connecting two Xbox one wireless controllers through an Xbox Wireless Adapter to a Windows 10 PC, and always playing my Xbox one console games on Win 10 by streaming, and those all went right and smooth, until the recent updates.

Now, with the latest updates of both the Xbox one console firmware ( 10.0.15063.3054/rs2_release_xbox_1705.170512-1759 ) and the Xbox App ( 29.29.17002.00000 ), only one ( the first working one when streaming starts ) controller is usable in streaming. No
matter in the home page or in game, only one controller is recognized by the console.

The two controllers are the original first gen Xbox one controllers (without 3.5mm jacks), both individually properly recognized by Windows 10 ( Win 10 Pro 1703/15063.296 ) and works well, even inside the Xbox app itself, except streaming.

Any suggestions?
