[Madwifi-users] Multicast/Unicast Frames

[Mad W. <mad...@ya...>]

Hi,

I got a transmission going in unicast mode at 54M. I am not quite sure how to find out how many retransmissions  I got but I would suspect there are not too many because the net rate is quite high.
If I set the mcast rate to 6,9,12,18 or 24 I've got a few dropped frames but nothing dramatic. Now if I try 36, 48 or even 54 then more than 50% of the frames are being lost. When I look at the frames in the receiver using athdebug +recv I can see that one frame is received correctly but the following one is directly attached to the previous one and therefore not recognized. I think that is happening in the Atheros chip itself and is not controlled by MadWifi but I am hoping that somebody has seen something similar or that it may be only a setup issue. 

Thanks,
Tom
