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.
Can you please provide more information on what are you trying to do here, it will give us much better context in how to reproduce/respond to your issue?
