I can confirm this has worked for me.
Over night left Nintendo World attwifi on(with no encryption) and got 6 hits
Switched it to the default 4E:53:50:4F:4F:46 and put encryption back on, no hits
Switched encryption off about 12 hours later and right away get a few more hits.
So it seems you...
I've been playing fallout4 all day, I went into a elevator and it kept going, never stopped, waited 5 minutes, must of been a bug. How bout you, whatcha do today?
