Hi Ian,

I don’t have another ‘decent spec’ machine to try Roon unfortunately.

My laptop is an i5 6300 CPU @2.4GHz-2.5GHz with 8GB Ram.....so I’m pretty sure it’s not the machine.

I’m also only streaming Tidal and not bothered to add my own library, so it’s not heavily loaded.

Scenario 1:
Lounge
Router to 1st Switch(netgear) which has MC200 Connected

A Single cable runs upto top floor connecting direct to 2nd switch

Music room

818 and laptop connected to 2nd switch

I am getting only 818 and MC200 dropping off Roon every couple of minutes....Sonos play 1 and 5 never fail. If I enable skybox and other devices they all remain stable and they are all using wifi.

(I have kept those off the device list for now so I can see more Easily see what devices keep failing in Roon......and it’s the 818 and MC200 only)

Scenario 2:

Remove 2nd switch from equation and connect 818 direct to switch downstairs. Laptop is then having to use WIFi.

All other devices remain very stable....again they are only using WiFi, 818 and MC200 keep disconnecting from Roon.

Scenario 3:

Remove 2nd switch, so connect 818 direct to laptop via Ethernet to USB adapter. 818 and all others devices are stable and MC200 keeps losing connection from Roon......laptop is connected via WiFi.......but I never get connection issues.

To me, this means it’s a switch issue if 818 works fine with direct connection......or should that be a Meridian issue with certain switches.....which I think is the case if others have no problems.

Problem is, how do I get 818 AND MC200 to BOTH work without a switch? There are 2x floors between them.

Even if bought a NUC I would need 3x Ethernet ports to eradicate the need for a switch And also still have to run a 2nd cable down the cavity.....I’m going to have to use at least 1x switch somewhere and in reality probably need x2.

I may look into getting a Cisco switch that has been suggested and try that downstairs and connect direct For now.

If that works I’ll need a 2nd one for upstairs......seems a bit of a pain to have to buy specific switches to get the Meridian devices to work whilst others are fine only using WiFi

If there is something else I can try let me know

Many Thanks
