This is a weird one. I signed up for the 14-day trial, and installed Roon 1.2 build 147 on my PC, Windows 10 x64 Pro. When I run Roon, my home network freezes up. The same thing happens when I install and run Roon on my MacBook Pro. After some testing, I discovered that, if I power down my Cisco SG200-26P switch, this doesn’t happen. The switch is not in the path between my PC/MacBook and my router out to the internet. It’s connected to a different port on the router, and manages my data and VoIP VLANs.
Roon is set to only look for music on the PC on which it’s installed. There are no other network devices enabled in Roon.
While Roon is running, if I power up the Cisco switch, the network freezes up again after a few minutes. It looks like a packet storm. There IS a network loop in my network, i.e. my VoIP switch is connected to the router, as is the Cisco switch, and the VoIP switch is connected to the Cisco switch directly. But those two connections are on different VLANs, If Roon is somehow broadcasting on both those VLANs, that might be causing a network loop.
So, my guess is that Roon does something to the network that causes a problem with that Cisco switch. Before I spend a ton of time with network analysis tools, can you please let me know what Roon tries to do to the network? I’m guessing that it probes it in some way, and it’s doing it every few minutes. Thanks!
