Apple TV Streaming Lag
I'm pulling my hair out on this. I have AT&T Fiber with the Pace modem/router. I am using a CAT6 wired connection from my Apple TV (series 4) to the router. I've tried various cables. Some - not all - apps are unwatchable because of lag. BBC America and Disney XD both have issues. I've turned IPv6 off on the router. I have no other router in the chain. Speed tests run on the Apple TV show it getting pretty close to max speed available. Yet, streaming lag. Here's the kicker: if I watch the same content in the same app on my iPhone connected to wifi it works perfectly. How is that possible? Edit: I have also created a custom profile for the Apple TV and opened the ports it requires.
