Hello, I caught the villain. I named him 11 september hack. this is what helped me - block multicast on bridge
/interface bridge filter add chain=forward in-bridge=bridge-vlan10-wifi-mall packet-type=multicast action=drop (optionaly mac-protocol=ipv6)
/interface bridge settings set use-ip-firewall=yes
And then locate multicast source from Wi-Fi point
