Hi, here’s my story:
My ATV3 was wifi connected, had a reserved IP and a strong radio signal. At random intervals the Airplay icon disappeared from my iPhone, iPad, MBP and Windows iTunes. In addition to that, ATV often could not be pinged! That suggested me that there could be a DOUBLE issue:
- Bonjour services broadcast was not running through my netwok (->no Airplay icon)
- ATV failed to switch wifi radio channels when the router automatically changed
channel (->ATV no longer in LAN).
After googling and investigating around I did the following to my system, achieving excellent results!!
- Manually open the following ports in the router (port forwarding): 3689,5353,1900,5351,5350,7000,5000,123,53
(I used both UDP and TCP “just in case”). For detailed info: https://support.apple.com/hr-hr/HT201733.
- Manually assign one fixed wifi radio channel : prevent the router from automatically
switch channel.
- Force ATV to connect in 2.4Ghz band.
ATV is now working for the last 24h, I am still doing some testing, stream looks good and
even wake up feature works! But I don’t trust this little black box anymore…
I think that the reason this problem persist is that manufacturers do not accept their
responsabilities: Apple think their stuff is perfect (and maybe using only Apple
hardware it is) and on the other hand most routers manufacturers ignore Bonjour
Services..Same old compatibility story!!
In my opinion AppleTv is the most “unfriendly” Apple device of all time.
