I think you've got that back to front - If I'm reading the
thread correctly the suspicion is the data is being transmitted
correctly by the remote end and is being lost somehere between
the rt2500pci antenna and user space.

The tools would still be helpful to see if a packet is being
received by the hardware and lost in the stack (maybe it doesn't
like something about the received packet) or if it is not even
getting as far as the rt2x00 driver.

Ivo,
Don't forget that there was no response to the request for someone to test
if broadcast packets were received in monitor mode on the older hardware
so if the filter flags don't select multicast traffic we could be losing
broadcast traffic too. I'm not sure if the stack will be reporting any
active multicast groups in AP mode. (For the benefit of others the only
reason normal broadcast traffic was working was because there was always a
multicast group present, Ivo's request is linked below.)
