nextbook keeps dropping wifi even though none of my other devices, laptops, etc have any problem connecting and staying connected. When I hit connect it says connection failed. Have to turn WiFi off then on again. Then it will automatically connect, and stay connected for about 10 seconds. It doesn't matter if none of my other devices are in use or not or how c close I am to the modem. I have removed my WiFi from nextbook and reinstalled. I have restored it to factory defaults with no help. Anyone have any ideas? Anyone?
