Q: Network time

Because you mentioned that you are setting up the iTunes store, I will first assume you are still setting up your new Apple TV. Is this is the case, use a website like canyouseeme.com to check if port 123 is open. If it is not, this is your issue of your Apple TV not being able to connect to the timeserver. Try contacting your Internet Service Provider for help with opening this port.

Otherwise, try hard resetting your Apple TV by disconnecting all power for 30 seconds. If the problem still persists, you may try hard resetting your router by also unplugging all power for 30 seconds.

Hope this worked out well for you. If you are having further troubles you can always connect it to iTunes using a micro-usb and restore it. Lastly, the Genius Bar will be more than happy to fix the problem for you if you'd like to make a reservation for your local Apple Store.

G'day mate,

I had this problem too, and it took me a while to sort it out.

So it turns out, here in Australia, only one Internet Service Provider (ISP) includes or uses the date / time function in their modems. This means, unless your ISP is Telstra, you will most certainly have the activation error you are speaking about.

To fix this problem, create a Personal Hotspot with your iPhone and connect your Apple TV to your iPhone. Activate the Apple TV, then you can go ahead and connect to your standard home WiFi.

Hope this helps.

Pete.
