The client has the latest patched orinoco_cs driver, and is a orinoco silver card with a 15db directional panel antenna (mounted on the mast) aimed at the AP. I've set the interface to monitor channel 11 (iwpriv eth1 monitor 2 11).
After more Ethereal snooping, I notice I'm seeing beacon frames from both radios on a few channels (1,2,11 about equal beacons from both radios, and a very small number of beacons on a few other channels).
Maybe this beacons/channel thing is not important. Does anyone know what affect this has in terms of network utilization? Clearly it would be better to have less broadcast traffic, but if some vendors are broadcasting beacons deliberately over multiple channels, maybe it doesn't matter that much?

One other possibility is that the receiver is near to a very high powered AP and there is enough energy in the signal to recover it far from its transmitted channel. This can be easily demonstrated with a Cisco 1200 AP, transmitting at full power (100mW) on channel 6. Within about 20 feet, the Beacons from this AP can be correctly received on all 11 802.11b channels.

Nope... Perhaps you have setup your AP to 'Search for best channel' and it is moving itself around the the lower utilization channel on a regular basis?

Should an AP be broadcasting beacon frames on a channel other than the one it's radio has been configured to use? For example, if my radio is set to use channel 1, should I see beacon frames from that radio on channel 11?
