Question 1

Does clearing the YouTube TV app cache on Xfinity WiFi delete my DVR recordings?

Accepted Answer

No. YouTube TV DVR recordings are stored in the cloud, not on your local device. Clearing cache only removes temporary app data.

Question 2

Why does YouTube TV buffer on my Smart TV but not on my phone?

Accepted Answer

Smart TVs often have weaker Wi‑Fi antennas compared to phones or streaming sticks. Connecting via an external device like a 4K Firestick can improve signal strength and reduce buffering.

Question 3

Could an Xfinity outage be causing buffering?

Accepted Answer

Yes, outages can cause buffering even on stable Wi‑Fi. Always check Xfinity Outage Map or the Xfinity app before focusing on your router or TV.

Question 4

Does a VPN help YouTube TV buffering on Xfinity WiFi?

Accepted Answer

Usually not. VPNs add extra routing and latency, which can increase buffering during live broadcasts. For the smoothest experience, disable VPNs on your streaming device and router when watching live TV.
