It's a Shuttle toaster look-alike with built-in (usb) wifi. Don't know
anybody around here with a wifi client that is capable of rfmon mode ...
or of linux even! (Not seen with NetStumbler under win2k).
I think you're right about it being a phantom. The other bit of
weirdness is Kismet doesn't indicate a channel for it. I can disable
channel hopping and stil see those reassociation request packets
arrive, regardless of what channel I'm watching.
Tonight I'll truck it down to the basement (radio blackhole) and
find out what I hear there.
