I use Roon and UPnP streaming via the new Sky router thing. I don’t rate Wi-Fi for this job at all so amost everything for streaming is connected to the router via homeplugs, or directly to the router via a switch in the case of the NUC that runs my Roon Core and the Innuous Zen that I use as a ripper and fileserver. I do have other endpoints (Auralic and Pi-based) connected wirelessly and without issue to the Router, but my main streamer (a Lumin) is connected via homeplugs. I had the same approach with the older Sky Router and with the Virgin Media SuperHub that preceeded it.
FWLIW I will probably put back in place the BT wireless mesh that this new Sky hub supposedly rendered redundant. This is simply because we get dropouts and network proximity errors on the Sky mini boxes in the kitchen and sitting room. This didn’t happen with our old setup with the BT mesh. I’m just too feckin’ busy at the moment to spend a day arsing around with Wi Fi settings on Sky boxes when I don’t really watch TV.
