First, find out where the problem is
Buffering means the video arrives slower than your TV plays it. The cause is almost always one of three things: your Wi-Fi, your internet line, or the device or app. A quick test tells you which:
- Does it buffer on every channel, or just one? One channel only usually means that channel's source is busy. Try it again in a few minutes, and tell support.
- Does it buffer on every device? If your phone plays fine on the same Wi-Fi but the TV doesn't, the TV's Wi-Fi or app is the problem.
- Is it only in the evening? That points to your internet provider being busy at peak time.
1. Restart everything, in the right order
Unplug the router for 30 seconds, plug it back in, wait until the internet light is steady, then restart the TV or box. This clears most temporary problems and takes two minutes.
2. Test your internet speed on the TV itself
Run a speed test on the device you watch on, not your phone. You need about 10 Mbps for HD and 25 Mbps for 4K per screen, and more if other people are streaming or downloading at the same time.
3. Use a cable instead of Wi-Fi
This is the single best fix. TVs and small sticks have weak Wi-Fi antennas. An Ethernet cable from the router to the TV, or an Ethernet adapter for Firestick, removes most buffering for good. If a cable is impossible, a mesh Wi-Fi system or a powerline adapter is the next best thing.
4. Move the router, or use 5 GHz
Walls, mirrors and fish tanks block Wi-Fi. Put the router up high and in the open. If your router has two networks, connect the TV to the 5 GHz one when it is close to the router; it is faster and less crowded than 2.4 GHz.
5. Clear the app cache
On Android and Firestick: Settings › Applications › your IPTV app › Clear cache (not Clear data, which removes your login). Restart the app afterwards.
6. Close what else is using the internet
Game downloads, cloud backups and 4K streams on other TVs all share the same line. Pause big downloads while you watch the match.
7. Change the stream format or player buffer
Many IPTV players let you choose the stream format (TS or HLS) and the buffer size. If one format stutters, try the other, and set the buffer to medium or large.
8. Lower the quality on a slow line
If your line is under 10 Mbps, an SD or HD version of a channel will play smoothly where the 4K or FHD version keeps stopping.
9. Check whether your provider slows streaming
Some internet providers slow video traffic in the evening. If everything works in the morning but not at night, and the speed test is fine, this may be the cause. A VPN can sometimes help in that case.
10. Update the device and the app
Old firmware and old app versions cause crashes and stutter. Check for system updates on the TV or box, and update the app from its store.

Common questions
Why does IPTV buffer only at night?
Evenings are peak time on home internet, so your line is slower. A cable connection and closing other downloads help most.
What internet speed do I need for IPTV?
About 10 Mbps per screen for HD and 25 Mbps for 4K.
Does a VPN stop IPTV buffering?
Only if your internet provider is slowing streaming traffic. Otherwise a VPN can make it slightly slower.
