Firing up the latest version of Roon (2.56 / 1582) on my MacBook Pro (M2 Pro, Tahoe 26.1) nukes my computer's ability to 'be' online, making Roon essentially unusable.
Network context is – 3 x LinkSys Velop 6E Mesh nodes, Roon Nucleus One hardwired into main unit, library is onboard the Nucleus, MBP is generally hooked into a satellite node that's wifi-connected to the main one. As soon as I fire up Roon on the MBP, the MBP's network connectivity goes off and on and off and on. It can (and has) settled down, but I've not worked out the circumstances under which that happens. At the moment, the problem's so bad that I'm just not firing it up, which means no music at my desk, which is a pain. I _think_ that it's just the MBP that's affected, but generally when I'm at my desk working I'm not using other network-connected devices (phone, TV, etc).
Describe your network setup
As above. 3x LinkSys Velop 6E Mesh Network units (MX6200). Roon Nucleus One hardwired into the main node (as in, the one that's connected to the phone line) via a Netgear 5-port gigabit switch (GS305). Modem is a BT Openreach one, 'G.fast modem', MT992.
Have you tried hard wiring the MBP into the yellow Ethernet ports on the back of the router? If you can, do so and see if the connectivity issues exist. Be sure to turn off the WFI though, or the computer will complain of another computer on the network using the same name.
Something clearly isn’t happy but, never had this issue with BT FTTP 900 or Sky on my BMP M2 Max.
And just to confirm, as you saying that when Roon is open, it’s cutting off the internet connection to the laptop. Therefore not being able to use the internet as normal?
I haven’t. I don’t thiiiink I have the ability to hardwire the MBP to the router. I’ll have a dig around my box of cables just in case, but mightn’t be any time particularly soon.
The network connection, when Roon is fired up, drops, then finds itself again, then drops, then finds itself again. I think one time it did manage to stabilise itself and it was plain sailing, but since then it’s been taking long enough to not stabilise that I’ve basically written it off as a thing to try (working from home = being online is important!).
