Well, most WLAN Access point really sux when it comes to multicast.
Sometimes, some tweaking allows to improve thigs a bit. For instance,
Multicast traffic is sent at the minimum speed allowed by the AP.
Multicast traffic is also buffered in the AP longer than unicast one in
most cases.

BTW, better use an address of the 239.255.0.0/16 for such tests.
224.0.0.0 is reserved for other protocols.
