How to fix IPTV buffering and freezing

Buffering is the most common IPTV complaint, and usually the most fixable. Work through these steps in order. Most people find the cause within the first five.

Speed requirements

Quality Stable speed per stream
SD 3 to 5 Mbps
HD / Full HD 8 to 10 Mbps
4K 25 Mbps

Run a speed test on the TV device itself. On a Fire TV Stick, use a speed-test app or the network settings. Results on your phone next to the router tell you little about the TV in the next room.

The fixes, in order

  1. Restart your router and device. Unplug both for 30 seconds.
  2. Use a wired connection. An Ethernet cable, or an Ethernet adapter for a Fire TV Stick, is the single biggest fix.
  3. Improve Wi-Fi at the TV. Use the 5 GHz band, move the router out of cabinets, or add a mesh point or powerline adapter near the TV.
  4. Pause competing traffic. Game downloads, cloud backups and other streams all share your bandwidth.
  5. Check your screens. Several streams at once need several times the speed. See multi-screen.
  6. Lower the quality for that channel or device if your speed is borderline. Choose HD rather than 4K.
  7. Increase the app’s buffer size. TiviMate: Settings > Playback > Buffer size. Other apps have similar settings.
  8. Switch the player engine. IPTV Smarters lets you change the player in settings, and some channels play better on another.
  9. Clear the app cache and free up storage on the device.
  10. Turn off any VPN. It adds distance and slows streams. See IPTV and VPNs.

Device-specific tips

  • Fire TV Stick: use the HDMI extender and the mains power adapter, and consider the 4K Max. See Firestick fixes.
  • Smart TVs: older TV processors struggle with large channel lists. A streaming stick often fixes it.
  • Laptops: plug in and turn off power-saving modes.

When it isn’t your setup

If every channel buffers on every device, even on a wired connection, check the service status and contact us. If only one channel buffers, tell us which, as it may be a source issue we can fix. To understand what happens between our servers and your screen, read how IPTV servers work.

Frequently asked questions

What internet speed do I need to stop IPTV buffering?

A stable 10 Mbps per HD stream and 25 Mbps per 4K stream, measured on the TV device itself, not on your phone next to the router.

Why does IPTV only buffer in the evening?

Evenings are peak time for UK broadband, and everyone in your home is online too. A wired connection and fewer competing downloads usually solve it.

Does buffer size help?

Increasing the app's buffer size can smooth out short dips in speed, at the cost of a slightly longer start time. It will not fix a connection that is too slow.

What is a buffer size limit on IPTV?

It is the amount of video the app stores ahead before playing. Larger buffers handle short interruptions better but take longer to start each channel.
