Oh, I don't want to debate the PCI guidelines, just saying that, which is what I started out with, I don't see much reason to have active scanning for four SSIDs. > I'll leave it up to you (collective you, not necessarily a personal > you), how to best deal with associating with APs which are not > broadcasting their SSIDs.
