Apple TV 3 won't show any networks
I have a Apple TV 3 and a IMAC and a Macbook pro and a Apple wireless router…I can connect using my iPhone,iPad and all the computers with no issues but the AT3 will not stay connected, it will either be connected and work for 5-20 mins and stream just fine and then lose connection and then I go to network and Wi-FI and it will not show any networks at all. I've done all the steps as far as a reset of the AT3 and a restart of the AT3 also a restart of the apple router along with the cable modem. It worked perfectly fine with no issues on 28th of August 2014 and I went away for the weekend and came home to a non working device. I'm losing faith in my AP3 I may have to change to a amazon fire box instead. I hope it's something simple, I haven't updated anything and everything is up to date my airport utility and my apple tv 3.
