How to Stop Buffering on Android TV: 12 Fixes That Work
Buffering is the most common video problem on Android TV. Few things are as annoying as a video that stops every few seconds with a spinning circle. Buffering means your TV is not receiving video data as fast as it plays it. The good news: in most homes the cause is simple, and you can fix it without buying anything. This guide starts with a 2-minute test to find the cause, then gives 12 fixes, from the easiest to the most technical. The same fixes also work on Google TV and Fire TV.
First: find where the problem comes from
Ask yourself three questions:
- Does only one channel or video buffer? If other items in the same playlist play fine, the problem is that specific stream (the server sending it), not your TV. Try again later. To understand how streams work, see M3U vs M3U8.
- Does everything buffer, in every app? If YouTube or other apps also stop, the problem is your internet connection or your Wi-Fi.
- Does it happen only in the evening? Your internet provider or the stream server is probably overloaded at peak time.
Check your internet speed on the TV
Open a speed test in the TV browser (for example fast.com), or install a speed test app from the Play Store. As a rough guide for one video at a time:
| Quality | Stable speed needed |
|---|---|
| SD (480p) | 3 to 5 Mbps |
| HD (720p / 1080p) | 8 to 15 Mbps |
| 4K | 25 Mbps or more |
“Stable” matters more than the peak number: a connection that jumps between 50 and 2 Mbps buffers more than a steady 15 Mbps.
12 fixes for buffering
1. Restart your TV and your router
Unplug the router and the TV (or TV box) for 30 seconds, then plug them back in. It clears temporary problems and memory leaks. It sounds basic, but it fixes a surprising number of cases.
2. Use an Ethernet cable if you can
A cable between the router and the TV is the single most effective fix against buffering. It removes Wi-Fi interference completely. Most Android TVs and boxes have an Ethernet port. If the router is far away, a powerline adapter (internet through the electrical wires) is a good alternative.
3. Connect to the 5 GHz Wi-Fi network
Many routers broadcast two networks: 2.4 GHz and 5 GHz (often with “5G” in the name). 5 GHz is much faster and less crowded, but has a shorter range. Choose it in Settings > Network & Internet on your TV.
4. Move the router or the TV box
Walls, metal furniture, aquariums and microwaves weaken Wi-Fi. Put the router high, in the open, as close as possible to the TV. If your box is behind the TV, an HDMI extension cable can move it a few centimeters into the open, which often helps a lot.
5. Reduce other usage on your network
Downloads, game updates, cloud backups and other people streaming at the same time all share your connection. Pause big downloads while you watch to avoid buffering.
6. Clear the app cache
On your TV, open Settings > Apps > WalisTV > Clear cache. Choose Clear cache, not “Clear data”: clearing data removes your local settings and favorites.
7. Free up storage space
When the TV storage is almost full, everything slows down. In Settings > Apps, uninstall apps you do not use. Keep at least 1 GB free.
8. Close apps running in the background
Budget Android TV boxes have little memory. Restarting the TV (fix 1) closes background apps. Avoid “cleaner” or “booster” apps: they often make things worse.
9. Change the DNS servers
DNS translates website names into addresses. A slow DNS can delay the start of streams. In your router settings (or in the TV network settings, if your model allows it), you can use a public DNS such as 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).
10. Update your TV and the app
Install system updates in Settings > Device Preferences > About > System update, and keep WalisTV up to date. Updates often include video and network fixes.
11. Turn off the VPN
A VPN adds a detour to every request and can cut your speed in half. If you use one on the TV or the router, test without it.
12. Contact the stream provider or your internet provider
If one source always buffers while others are fine, contact the provider of that source. If everything buffers even with a cable, ask your internet provider to check your line.
Buffering vs “does not play at all”
If a playlist or a channel does not start at all, or shows an error instead of loading slowly, it is a different problem: the link may be wrong, expired or offline. See how to fix a playlist that does not load.
Avoid buffering while watching in WalisTV
- If a live channel freezes, switch to another channel and come back: the stream reconnects.
- For movies and series, pausing for a few seconds lets the player load ahead. Audio, subtitles and picture size are in the player settings.
- Use Left and Right on the remote to go back or forward 10 seconds. See the remote control guide.
Buffering quick checklist
- Only one stream buffers → it is the source.
- Everything buffers → network: cable, 5 GHz, router placement.
- Only in the evening → peak-time overload.
- Still slow → clear cache, free storage, update, DNS, no VPN.
Important: WalisTV is a media player only. It does not provide channels, playlists, subscriptions, movies, series, or streaming content. Use only playlists from sources you are legally authorized to use.
