7C:9A:54:FC:7E:7F is a Tecnicolor CH USA device. Do you have any such
devices?

 It must belong to a neighbor. My AP is d-link.zefox.net, a DI-524.

And that is its SSID?
I didn't think you could put full stops in an SSID
Oh. The spec says you can. Other people suggest that some clients cannot deal with odd characters.

What motivates the question?
