imho, routers either handle this somehow or drop packeta. because mdns is higher level protocol than wifi and mac, router should not deal with those.

also, with same hardware what happens there is whatsapp/hangouts video call? its about firmware

Routers deal with IP traffic (and even have to mess with TCP, e.g. clamp MSS), not just the 802.1 and 802.11. For SOHO routers, high PPS multicast UDP may be something hardware-accelerated routing doesn't particularly account for. And if software routing kicks in, high packet rate can very easily overload poor device's CPU.

It's due to the way multicast packets are transmitted on Wifi...
