Hello,
Recently a message started to show up intermitently about loop detection.
I’ve changed the MAC Address from wlan, disabled Neighbor discovery, searched in the network for a similar MAC Address.
The system is running all interfaces on a bridge.
Any ideas?
Hi.

I have same problem on Bridge with eth and vlan interface

No, still waiting a solution… Changing something and still the problem
Maybe someone in your lan add a hub to extend ports capacity and plug it in the switch?
