Hi Miron,
Have a look at this info,it looks like you need to set at least one of the radio speed settings to basic to pass multicast traffic;
2.4-GHz Radio (dot11radio0)
speed
{ [1.0] [2.0] [5.5] [11.0 ]
[basic-1.0] [basic-2.0] [basic-5.5] [basic-11.0] |
range |
throughput }
(Optional) Sets the access point to allow packets to use the non-basic settings. The access point transmits only unicast packets at these rates; multicast packets are sent at one of the data rates set to a basic setting.
Note At least one of the access point's data rates must be set to a basic setting.
For the 2.4-GHz radio:
[ basic-1.0 ] [ basic-2.0 ]
[ basic-5.5 ] [ basic-11.0 ]
(Optional) Sets the access point to require the use of the specified data rates for all packets, both unicast and multicast. At least one of the access point's data rates must be set to a basic setting.
Note The client must support the basic rate you select or it cannot associate with the access point.
