How to Fix Live Stream Buffering

Few things are more frustrating than a live stream that keeps stopping to load. The good news is that most buffering has a handful of common causes, and you can fix live stream buffering yourself in a few minutes. Work through the steps below in order, starting with the simplest.

Why live streams buffer

A live stream cannot download far ahead the way a recorded video can, because the next few seconds have not happened yet. The player keeps only a small buffer, so any dip in your connection speed, a busy home network or a slow server shows up quickly as a frozen picture or a drop to lower quality.

Check your internet speed

Run a speed test on the device you are watching on, not just on another device in the house. Compare the result with what the video quality needs. YouTube recommends these sustained speeds:

4K: 20 Mbps
1080p HD: 5 Mbps
720p HD: 2.5 Mbps
480p SD: 1.1 Mbps
360p SD: 0.7 Mbps

Netflix gives similar guidance: about 3 Mbps for HD (720p), 5 Mbps for Full HD (1080p) and 15 Mbps for 4K. These are per stream, so if other people in your home are streaming, gaming or downloading at the same time, you need more. You can check YouTube’s figures on its system requirements page.

Wi-Fi vs a wired connection

Wi-Fi is the most common cause of buffering. Walls, distance and interference from neighbouring networks all reduce the real speed your device gets.

If you can, connect a TV or computer to the router with an Ethernet cable. It is almost always more stable than Wi-Fi.
Move closer to the router, or move the router to a more central, open spot.
If your router offers a 5 GHz network, use it at short range. It is usually faster and less crowded than 2.4 GHz.
Restart the router and modem. It clears temporary faults and often helps more than you would expect.

Lower the quality on purpose

Most players have a settings or gear icon where you can choose the resolution. If the stream keeps stopping, switch from “Auto” to a fixed lower setting such as 720p or 480p. A steady 720p picture is far easier to watch than a 1080p picture that freezes every minute.

Browser and app tips

Update your browser or the broadcaster’s app. Old versions can have playback bugs.
Close other tabs and apps that are playing video or downloading in the background.
Try a different browser. If a stream works in one and not another, an extension (often an ad blocker or privacy add-on) may be interfering with the player.
Clear the browser cache for the site, or try a private window to rule out stored data.
If a site’s own player struggles, open the official app or the broadcaster’s YouTube stream instead, if there is one.

How a VPN affects streaming

A VPN sends your traffic through another server, which adds distance and can reduce speed, especially if the server is far away or busy. If you have buffering problems while a VPN is on, turn it off and test again. Many streaming services also detect VPN traffic and block it, and some prohibit using a VPN to get around regional restrictions in their terms of use.

Geo-blocks are not buffering

If the player shows a message such as “not available in your country”, or stays black without ever loading, the stream is probably geo-blocked rather than slow. Broadcasters often hold rights to programmes for their home country only. In that case, look for an official YouTube stream from the same channel, or choose another channel. Our guide on how to watch live TV online legally explains geo-blocking in more detail.

Device tips

Restart the device. Phones, smart TVs and streaming sticks all benefit from a fresh start.
Keep the device’s software up to date.
Older smart TVs and streaming sticks may struggle with newer video formats. Casting from a phone or using a newer device can help.
On a phone, check whether you are on mobile data with a weak signal or a data saver mode that limits video quality.

When the problem is the stream itself

Sometimes the issue is at the broadcaster’s end, for example during a major breaking news event when many people tune in at once. If several channels play fine and one does not, wait a few minutes and try again. On TVOPEDIA, if a channel’s link is broken or no longer works, use the report form on the channel page so it can be checked.
