My daughter got a tablet for Christmas, and up until a few days ago, it connected to our home network without issue. Nothing changed in our network or her tablet, but now when you search for open wifi networks, nothing happens. The "on" button usually lights up blue, and a list of available networks will show up. Now, when we switch the button to on, it stays gray and the screen says "To see available networks, switch to On". Any help would be greatly appreciated!
