Multicast over WiFi does not work.
Multicast communication does not work properly when two devices are connected wirelessly to the RAX40 router.
In the wired environment, I checked that the Wireshark tool sends and receives multicast packets normally, but in the wireless environment, I cannot receive the multicast packets.
some routers, including rax40, appear to have chronic multicast issues.
Please see the two links below.
I appreciate your prompt feedback.
