Xbox One Game Streaming issue with Netgear Switch

I thought I'd write a post about some problems i've had with game streaming from my Xbox One S in the hope it may help someone.

My network infrastructure is crudely documented in this diagram.

The equipment list is as follows:
  • Xbox One S 500GB
  • 2 x Sumvision 1000Mbps Powerline adapters
  • 2 x Netgear GS108 Gigabit switches
  • HP Laptop with gigabit NIC
The problem is an "artifacting" effect of the graphics almost blurring momentarily, then the game snapping back into life.  It can be bad enough to be unplayable.  My quick test for this now is to quickly scroll up and down as fast as I can on the Xbox home screen.

I swapped the switches, swapped cables, tried new cables, turned off the energy saving mode on my NIC to no avail.  Every other device on both sides of the powerline function absolutely fine, I can stream 1080p content without issue for hours on end.

One magical day I figured it out.

The way i fixed it was swapping out the Netgear GS108 switch which the Xbox One S is connected to, I swapped it for any old switch I had lying around (It happened to be a Netgear WNR2000v2 which had DD-WRT installed on it).  I still get SOME artifacts,(update, 2nd session of gaming had no artifacts) but 95% less than I had before, and an amount i've always experienced when game streaming, so this is acceptable to me.  Eventually will replace my other Netgear switch in a bid to eliminate all artifacts, but I thought I'd post in the unlikely event someone is suffering the same problem as myself!
