Viewers complain about buffering or stuttering video

Buffering or stuttering video?


When you stream live, as a rule, some viewers will have problems. It can be due to many things but the most common reasons behind the problems are just like everything else where technology is involved and should work for lots of different people with different devices and connections. However, we would like to point out that live streaming through Streamio usually works, but in the event of problems, the following aspects can be reviewed:

Streaming quality

Streaming with higher quality increases the risk that some people will experience problems such as buffering. The streaming capacity is connected to your connection and that of your viewers. Lowering bitrate, the quality of the stream, is a sure way to minimize the problems even for those with weak connections. Learn how to change live streaming settings here!

3G/4G Connection

3G and 4G are mobile data that is usually reasonably fast but unstable. Viewers who are mobile connected are more likely to have problems than those with fixed connection. Even if you have a good connection, the performance varies over time with the number of users on the same cell and what they do. If you are in motion, for example if you are riding in a car or sitting on a train, you jump between different masts and get completely different performance for each jump. If you can’t switch to fixed WiFi or preferably wired connectivity, the only action you can take is to lower the quality of the power so that more people can handle it.

WiFi connection

Today, the common man almost takes WiFi as a guarantee that you would have a good connection.


In fact, quite a few WiFi networks are unreliable with poor performance. In addition, WiFi signals vary depending on the user’s load, so just because you’re connected to a WiFi doesn’t guarantee you won’t experience buffering in your live streaming.

Now that many people have moved their workplace from office to home office, new WiFi problems may have arisen. To get the best possible wireless connection and minimize problems, you can read this blog entry for 10 tips to boost your WiFi coverage (External link). Here we summarize some basic tips to make your WiFi work better

  • Always update your router to the latest firmware version.
  • If you have an old router, consider whether you should replace it with a newer and faster one.
  • Make sure that all computers connected to the WiFi network have the latest drivers for their network hardware.
  • Keep your devices up to date with the latest versions of the operating systems, Windows, MacOS, Android, iOS.
  • The signals that WiFi runs on are often full of traffic. Try using the 5-gigahertz band for the devices that can receive it, as a rule, it is faster than the standard crowded 2.4 gigahertz band.
  • If you still have problems, you can try moving your router, a bit above the ground and close to your worksatation, that usually does the trick.
  • There are apps for mobiles and applications for PCs to help you measure the performance of your network. If you have a lower speed than what you pay for, you should contact your Internet Service Provider (ISP).


We hope that the above tips can minimize buffering of video and other issues like stuttering video. If possible, we always recommend that our users and viewers of live streams use cabled connection instead of WiFi, so you avoid all forms of buffering.

Encoder connection

The same thing mentioned around mobile and WiFi connections above naturally also applies to the encoding page – it is important to make sure that you have extremely reliable and sufficiently powerful connection where you stream from. Expect to have at least 10 Mbps available to stream at 3 Mbps to have appropriate marginals.

Encoder performance

The right settings for the right hardware. Something that pops up relatively often is interference due to overloading the hardware. Encoding video is heavy, and it’s pretty easy to overload your hardware. Examples of this are OBS Studio poor quality, hacking, freezes.
