I'm probably romanticizing and projecting, but I imagine that scenario going something like this:
* lrvick knocks on guilty neighbor's door.
* guilty party's non-technical brother answers
Brother: Yeah?
lrvick: Hey, I notice you guys have an antenna on the east side of your roof pointed at my house, is that yours?
Brother: Huh? No, that's my sister's.
lrvick: Is she around? It's messing with my Netflix and I'd like to talk to her about it.
Brother: Oh, um, yeah. hold on...
* Brother leans away from door into house and shouts inside, "Hey sis! Neighbor at the door for you!"
* lrvick waits.
* Guilty sister walks up to door
Sister: Can I help you?
lrvick: Is that your antenna on the east side your roof?
Sister: Yes.
lrvick: So, the past month, someone's been messing with my wifi with deauth attacks.
Sister: *mildly indignant* I'm not doing that.
lrvick: Well, The past week, I spread a bunch of sensors around my property and a couple of the neighbors and logged the 2.4Ghz spectrum for the area. I correlated everything and triangulated the attacks to that antenna of yours, which just so happens to be aimed at my house. Here's the logs and spectrum heat maps if you'd like to see.
* lrvick offers Sister the printouts he brought with him.
* Sister takes, looks them over and starts to get that embarrassed flush in the cheeks and ears characteristic of someone who knows they're busted.
Sister: I mean --
lrvick: I'm actually not even mad. It's kind of illegal, but it's also ballsy and I respect that. But I'm not the kind of person to go snitching to the FCC first thing. You do know if we're competing for spectrum, you can come talk to me, and we can coordinate a plan over a couple beers, right?
* Three months later lrvick and Sister are co-presenting a talk at the local hackerspace on counterattacks to deauth attacks.
If someone came at me with a deauth attack I would be incredibly amused and probably make a new friend.
