Apple TV performance issues can take the form
of:
Lag
App crashes
Reduced video quality
Lower frame rate
Slow motion video
Out-of-sync sound
Long buffering times
Please see the below steps to improve the performance on your Apple TV to get
it running like new again.
Restart your Apple TV:
Restart your device by selecting Settings > System > Restart.
Alternately, you can force restart your Apple TV by simultaneously holding
the Home and Menu buttons on your remote for
about 10 seconds, until a white light on the Apple TV starts flashing.
Then, release the buttons on the remote to restart the
device. You can also unplug your Apple TV, wait 30 seconds to a minute, and plug it
back in.
Connect to the Closest Base Station:
If your Apple TV device is connected to WiFi, and you have
multiple base stations in your home, make sure your Apple TV is connected to
the one it is located closest to for the fastest streaming. If you have recently rebooted the nearest base station, your Apple TV may have
connected to one further away, resulting in weaker signal strength. Rebooting
your Apple TV should allow it to reconnect to the nearest base station.
WiFi vs. Hard-wired Connection:
Try disconnecting and reconnecting from your WiFi network
by going to Settings > General > Network > WiFi.
Select the name of your WiFi network, then Forget
Network. Reconnect to the network to see if the streaming
speed improves. Try connecting your Apple TV directly to your router or modem via an Ethernet
cable to see if this improves streaming speed.
Congested Internet Connection:
If other devices on your WiFi network are running
downloads, uploads, updates, or streaming video, this may saturate your
internet connection and cause slower streaming.
Reset Your Apple TV’s Settings:
This can sometimes remove corrupt files that may be
causing your Apple TV to run slowly.
Go to Settings > General > Reset > Reset
All Settings.
Restore Your Apple TV:
If none of the above options improved your Apple TV
functioning, you can try Restoring. Please note after restoring you will need
to reconnect to your WiFi network, and you will be signed out of apps.
Go to Settings > General > Reset > Restore.
NOTE: Do not unplug your Apple TV while the Restore is in progress.
