I question the value of making the "busy environment" even more busy by sending a lot of probe requests at low rates ... Scans are never really guaranteed to be perfect and complete anyway. This is clearly your choice, but given, among other things, the broader industry direction of moving away from active scanning this seems like a bit short-sighted thing to do. johannes
