Dear tp-link customer support,

This is the same issue I asked about previously in the following thread:

https://community.tp-link.com/en/home/forum/topic/662230

Last time it was the BE805, but this time the same phenomenon is occurring with the BE900.

Just like with the BE805, if you place the Hikari TV tuner (STB) and the device in AP mode (BE900) directly under an L2 smart switch that supports MLDv2 snooping and turn on the BE900, the Hikari TV broadcast that you were able to watch will stop.

Both IPv4 and IPv6 are connected to the Internet, but the Hikari TV multicast packets will stop.

If you turn off the BE900 and wait a while (about 2 minutes), you will be able to watch Hikari TV.

This is exactly the same as with the BE805 last time.

Furthermore, this time I have also placed the BE805 in the same row, but this one (unlike the BE900) does not get in the way.

Last time with the BE805, you transferred the issue to development and released a beta firmware to deal with the problem, but would you be able to do the same this time?

Best Regard.
