Hi,

Thanks for the reply.

Setup is simple PC1 <wired> STA <Wireless> AP <Wired Gateway> PC2. Multicast
traffic is going from PC1 to PC2.

So, rate control algorithm is there in hardware or in driver itself ?. I
have snifffe the packet using aeropic and found that the rate in multicast
frame is more that 6 Mbps.

Thanks,
Mitul Modi
