Wrong. If the other machine located your node, then one of the four statements is true: a)beacons are working b)probes are working - which means a scan is happening. c)beacons and probes are working d)beacons and probes are not working. The vista machine saw a data packet, and sent a probe request, which your machine answered.
>>>>>>>> My colleague here did some work with a slightly older kernel. He found that the association process worked sometimes - not always. There was a time dependency - both nodes have to go through this at the same time. Further - scans - it seems that nodes have to scan to find things. Old information in the mac80211 has to be expired and removed. A scan should not be necessary - if both ends are put on channel 2462- a scan should not be required - there is no channel changing. Yet - my colleague noted a scan helped nodes to associate. I would say this::: I cannot deduce what is happening from the initial posters report. I need a packet dump of the beacons/probes and all the other packets on the air.
