Hi, Welcome to the community.

How did you find "When a device sends a multicast message, it is received twice by the receiving devices"?

Do you have any pictures or log files to share with us?

Best regards.

Hi,

I attach Wireshark capture of a multicast message received twice.
Wireshark is running in a PC connected via ethernet to the FO router.
The sender device (192.168.1.17) is connected via WiFi to the deco X50 AP.
The replication happen in all devices connected to the deco X50 AP
There is not replication if I don't use deco X50 AP and active the router WiFi AP.

Regards.

@JPMJPM

Thanks for the pictures.

I would like to forward your case to the senior engineers for further assistance. Please check whether you could get an email from support.forum later.

By the way, it might not be relevant and I wonder whether you have noticed any abnormal network issues on the receiving device?

Best regards.
