Okay, I rooted my s4 and installed Wifi Tether for Root Users. When I first installed it worked perfect, for about 3 hours. Now it is a nightmare. It will start up fine, no errors, the devices will connect flawlessly (Xbox usually, occasionally laptop, kindle, 3ds) then it will work for about 10 to 15 minutes and shut itself off. If it doesnt shut off every time I get a text, call or just unlock my phone it give me the "What the hell! Phone has taken back control." message. I've tried playing with the settings but I'm at a loss. I'm embarassed to say but I'm on house arrest and I have no cable or internet and am paying for Netflix and Xbox Live so this is driving me insane and not having at least my netflix is driving me up the wall. If anyone can help I would highly appreciate it. I'm kind of new at this so in your answers try to dumb it down for me please lol.
