Apple TV Gen 1

Is your Apple TV really 1st generation?

• If your Apple TV is a 4" black box, then it is at least 2nd generation.
• If your Apple TV supports streaming from a phone (AirPlay) at all, then it is at least 2nd generation.

(1st vs. 2nd generation)

"Apple TV Gen 1: Have an 1 Apple TV that give me a 'Signal too weak' issue so I can’t stream to it from my phone. Also have problems connecting to my Apple ID. What can I do to fix?"

Your Device is Obsolete:

There is no fix, but an upgrade to Apple TV Gen 3 or after - Being an obsolete device, it will not connect to the iTunes Store, as of May 25, 2018, Go Here: If you can't Access the App Store or Other Apple Media Services, or can't Edit your Payment Information - Apple Support
