Buffering is almost always a network issue rather than a content issue. Work through this checklist in order — most problems are solved by step two or three.
1. Restart your router
Unplug it for 30 seconds. This clears a surprising number of connection issues.
2. Check your speed
Run a speed test on the same device you're streaming on. You want at least 15 Mbps for HD, 25+ Mbps for 4K.
3. Switch to Ethernet or 5GHz Wi-Fi
Wired connections are the most reliable. If Wi-Fi is your only option, use the 5GHz band and stay close to the router. Our Smart TV settings guide covers this in more detail.
4. Close background apps
Other apps or devices on your network competing for bandwidth (large downloads, other streams) can starve your stream. This matters even more in multi-device households.
5. Message us
If none of the above helps, send us your device model and a screenshot of a speed test — we can usually pinpoint the issue quickly. Our Contact page has every way to reach us, and our FAQ covers other common questions.
