I'm having issues with my apple tv. I only see Computers and Settings now. I am connected to my wi-fi however the network time is not set and that is preventing me from doing anything. How do I set the network time?? I've tried everything I can think of. I've restarted my apple tv using the restart function. I've also unplugged all the cables for a few minutes and plugged them back in. I've set my location. I've checked my network settings; made sure my isp's dns matches my router. What else should I do???
