So when I'm at work I've been connecting to an xfinity hotspot on my phone. I'm a caretaker so surrounding me are houses/apt. I've used it for months however the past few days it won't connect. Sometimes it will start to then stop and say 'disabled' or it'll say 'saving' then go back to available. Occasionally it will connect but the service goes all over (never done that before) it'll go from full bars to none to half to full to none before disconnecting. And I'm sitting in the same spot! Is it possible the neighbor turned off hotspot and that's why?
