MikroTik

I'd setup a hotspot with rb951 that use TPLink wr841HP as an access point . I wonder to know is it possible to use ap DHCP server instead of the router. I disabled the DHCP server in router board but my devices don't get the IP and when I check the log window in winbox it says:
interface warning ether2 exccessive multicast/ broadcast, probebly a loop

Thanks
