Someone on my street made their exact street address their SSID. 
Also, a lot of nearby Bluetooth Low Energy devices aren't nearly "low energy" enough.
Correction: Two houses have done the last-name SSID.
Did I mention it's fun living in a highly crowded Wi-Fi environment?
@voltronic I thought every street had a wifi SSID of "FBI surveliance van."
@Keysalagain
Secret Service Surveillance pops up now and then.
@voltronic
Want a laugh?
I have no idea how to change my SSID!
I'm sure it's not difficult, I've just never learned.
@voltronic I haven't looked in a while. I have the couple neighbors I know (no address or last name, one first name,) but now I have an "Actiontec-3110-2.4G", a "DIRECT-FF-HP OfficeJet Pro 7740", an "XfinityArris9999" (all secure) plus a new one to have fun with:
*UNSECURE* "Sengled_Wi-Fi Strip_0E38" - someone's "smart" LED light strip. Time to have fun with some light patterns!
@voltronic Aw, they finished setting it up before I could. 😂
This is in addition to the people down the street who made their last name their SSID.
