There are several problems with multicast over 802.11, such as
throttling and inefficiency of error correction (there is no
retransmission for multicast as for unicast).

In practice, multicast over WiFi is only usable for very small
bandwidth usages, such as discovery protocols.

As such to stream over WiFi, you should always use unicast, even
if this means wasted bandwidth when there are more than one
client associated with a given AP.

Some AP might allow tweaking some settings, but you should refer to
the AP documentation. Unlikely to solve the problem anyway.
