I don't mean to start an argument, and I do not work for Roon, but the odds that this is a Roon problem are infinitesimally tiny. I'm sure Roon has its problems - it's software - all software has its problems - but I've used and abused Roon for years over varying wired and wireless networks (including via VPNs from my Core in Boston to endpoints in my office and apartment in NYC). Getting data from point A to point B has never been a problem for it. Ever. Not once. It's kinda Roon's raison d'etre, one might say!When this has happened with Poly, it’s generally turned out to be the connection/outer. Try rebooting the router and the Roon core and see if that helps. If not, a new router could be in order.
I still haven't been able to get 2go to work properly on my (2019 Linksys) WiFi network. Though I haven't tried that hard - I must admit (I shouldn't have to, presumably). I have like 20 other devices that work perfectly fine on my WiFi (half a dozen Sonos's, five phones, three tablets, five laptops, three printers, a NEST, a TV, a couple Chromecasts, and who knows what else is freeloading!).
Old routers seem to pop up anecdotally here. But nobody had explained why this might be a problem.
