What channel are you using?
What is your setup? Does the multicast traffic is sent from STA to AP or
the opposite ?
Unicast traffic is controlled by the rate control algorithm, trying to
achieve the best performance.
Multicast traffic is not under the rate control algorithm and since it
cannot be retransmitted, nor ACKed, it is transmitted at 1 Mbits rate in
802.11bg and 6 Mbits rate in 802.11a.
Regards,
Benoit
