AT A LOSS - Apple TV Suddenly Stops Working

Question

Quick background -- I have an eligible MacBook and the newest AppleTV and everything has been working ok for months. Suddenly, no AppleTV icon on my MacBook (or my iPhone for that matter). I tried everything -- restarting, resetting the AppleTV... and then when I finally decided to try resetting the router and resetting everything else again, the icon showed up! But it didn't work (when I clicked on the icon and turned on mirroring, nothing happened). And then it disappeared again. All software is up to date, and I haven't seen any other tips in other threads that have worked. Again, my hardware is eligible/compatible and everything has been working fine for months. Any thoughts?

Answer 1

if your wifi router still have the default name it came with and several networks in the area is using the same name that could cause issues
another thing which could cause issues is if many wifi networks in the area use the same wifi channel as your wifi router
another thing then the "default" 2.4Ghz wifi band is a very very used band microwave ovens, dect phones, bluetooth and many other things use 2.4Ghz
and that can cause disturbances so if your setup support 5Ghz wifi then it can at times be more stable
another thing is that router manufactures now and again fix bugs and release new firmware for the routers so one can at times benefit of updating the wifi router firmware for better compatability
