I don't think this is a normal issue.. I was able to use FoxFi 3 days ago so that my grandmother could download an update to her tablet, yeah she used up about 100Mb but I've played Battlefield for hours on FoxFi and had no problems. Now all of a sudden, it says wireless tethering is on but nobody is picking up the signal and there's no stock app notification anymore either. I'm non-rooted, so my phone hasn't gone through an update and the app hasn't been updated either. Restarts don't do anything, I can't figure it out.
