RB750 multicast routing on 2 ethernet ports

I’ve got my rb750g today morning. I finaly got multicast routing working on my wired pc, but then i found, that my wireless goes nuts, (about 6Mbit/s are sent on AP from rb750, when I watch some TV show) and the web pages is opening very slowly.

How can I limit multicast only to wired PCs, and how to boost performance of opening web pages. Now I have basic configuration on rb750g with master-slave / switched ports.

PS.:By wireless i mean, AP on my ether3 port.

Hi,

How have you set multicast settings (PIM,IGMP-Proxy)? What is your RouterOS version?

Thaks for any help.
