Network problem: MS Surface Pro 7 (Remote) intermittent connection with Google Nest WiFi - and Core

@support

Core Machine: 7i7BNH Intel NUC w/Windows 10 Pro 64bit
Network Details: Deutsche Telekom W724V (WiFi off), 2 Netgear dumb switches, CAT6/7 cabling, Google Nest WiFi Hub + 2 endpoints
Audio Devices: Meridian 861v8+ID41, Meridian 218, Meridian 251 (all wired connections)

Description Of Issue: Due to very patchy WiFi in my apartment I’ve just added a Google Nest WiFi system with 1 hub & 2 endpoints. Until then - if I had a WiFi signal on any of my regularly used Remotes (Surface Pro 7 & Surface Pro 3) - connection to the Core would either remain or be re-connected after regaining the WiFi signal.

Since installing the mesh system, the WiFi has of course been far better, but I have regular - almost daily - disconnects from my remote - and then the remote won’t re-connect without a reboot of the Core.

I suspect some setting within the mesh system - perhaps DNS? I believe the mesh system - which is hard-wired (the hub) to my Router - has its own subnet.

Anyone have experience with settings for a Google Nest WiFi system that could explain - and fix this?

Hello @rolski,

Do you by any chance have a Multicast / IGMP Snooping or IGMP Proxying setting on your router? I’d give that setting a try, it has helped with multicast issues with other routers in the past, see: Networking Best Practices Guide.

Thanks for the quick reply @noris

No - as far as I can see - after going through all the Router settings & searching the web, the Router doesn’t have the option or capability of IGMP / Multicast.

And all the switches in my network are Netgear consumer-grade / dumb.

Hi @rolski,

When do these disconnects typically occur? Do they only happen when you are moving between rooms and the Surface’s are switching between access points or do they occur in the same spot as well?

If instead of rebooting the Core you try to reboot the Roon app on the Surface, does that allow re-connection?

Hi @noris

Disconnects do occur when moving between rooms, yes.

If I stay in the same room & the ‘Remote’ goes to sleep, it’ll start up again & show that it’s searching / connecting - and reconnect successfully very quickly.

If I move rooms & lose connection, then close Roon & restart Roon, it searches for the Core ‘forever’, even when I help by enterering the Core’s I.P. Address.

Note: Remote has lost connection overnight without being moved or shutdown - but a restart of the Core (not a reboot of the Core machine - only a restart of Roon on the Core) resulted in immediate re-connection).

Hello @rolski,

I wonder if the IP address lease expiring is part of this issue.

Could you please try setting Reserved IP addresses for both your Core + remotes and verify if that helps with these issues? This article provides instructions.
