I'll take a look at those locations, thanks. It might just be arp that's the authenticated client data store from the point of view of the wireless interface.
I do know German, I'll see if I can get the book, or if I even need it after I poke around. My OpenWrt router got fried by a remote electric directional beam of a digital weapon from an apartment across the wall a few years ago. Even a simple digital thermometer near the router was getting broken and showing weird stuff on display. How can this be legal? We must mandate RF detectors in all homes for everyone's electronic device safety and personal safety. I'm 100% cabled at home for a while now too, but trying to see if I can make this hostap work in OpenBSD, since it's the golden standard for security? Thanks again for your help.
