Nothing ruins a game or a movie night like the spinning wheel. The good news: most buffering comes from a handful of fixable causes — weak Wi-Fi, a busy network, outdated apps or a device that simply needs a restart.
Work through these steps in order. Most people solve the problem in the first three.
In this guide
1. Check whether it’s the service
If only one app is buffering, the issue may be on the provider’s side, especially during big live events. Check the service’s official status or help page and try another app. If everything is slow, the problem is closer to home.
2. Restart the device and router
Unplug your streaming device and your modem/router for about 30 seconds, then plug the modem in first, wait for it to fully connect, and then the router and device. This clears temporary glitches and memory issues.
3. Test your internet speed
Run a speed test on the device itself if possible, or on a phone next to the TV. Compare the result with our recommended speeds. If you’re far below your plan’s speed only on the TV, Wi-Fi signal is the likely culprit.
4. Improve your Wi-Fi
- Move the router to a central, elevated spot away from metal objects and microwaves.
- Use the 5 GHz band if your device supports it; it’s faster over short distances.
- Connect with an Ethernet cable or adapter for the most stable stream.
- Consider a mesh Wi-Fi system for larger homes.
5. Update and clean up
- Install system and app updates.
- Close or force-stop apps running in the background.
- Clear the app’s cache (where your device allows) or reinstall the app from the official store.
- Free up storage if your device is nearly full.
6. Reduce competition on your network
Large downloads, game updates, cloud backups and video calls all compete for bandwidth. Pause them while you watch, or use your router’s quality-of-service (QoS) setting to prioritize the streaming device.
7. Lower the quality temporarily
Most apps let you choose a data-saver or lower quality setting. Dropping from 4K to HD can stop buffering instantly while you fix the root cause.
When to call your internet provider
If speeds are consistently low on a wired connection, or the connection drops at the same times each day, contact your internet provider. Ask them to check the line and your modem, and whether your plan fits the number of people streaming in your home.
Still stuck?
If buffering only happens with one unofficial or sideloaded app, that app is the problem. Licensed services in official app stores are built for reliable delivery — read how to spot illegal IPTV to learn why.
