This usually happens when both LAN ports on RoomHub are connected to the same network.

RoomHub has two independent ports:

• LAN 1 - control and management

• LAN 2 - AV Network (AV and Dante traffic)

They are fully isolated inside the device.
There is no bridging or forwarding.

But when both ports are plugged into the same broadcast domain, some switches may treat this as a loop and raise warnings.

Use separate networks.

• Connect LAN 1 to the control or corporate network

• Connect LAN 2 to the AV or Dante network

That’s the intended setup and immediately resolves the issue.

If you don’t need AV/Dante traffic yet:

• Disconnect LAN 2

• Run RoomHub on LAN 1 only, while setting up the AV Network

If you see loop warnings:

• Check where LAN 1 and LAN 2 are connected

• Don’t place them on the same network

Separate control and AV traffic, and RoomHub works as expected.
