How to prevent Buffering
The main underlying reasons for buffering can be categorized in 3 main sections: Internet speed, hardware processor, and the server through which the IPTV is streamed. The fluctuation of the Internet download speed will lead to buffering. Also, if your TV or media box is unable to handle the high-quality input streams (for example HD channels) this can cause buffering.
Finally, when the servers of the IPTV providers are being overloaded as a result of over-streaming by the users, this will cause buffering too. Moreover, if you use VLC, KODI media players or a Smart TV app, you might look into the ways by which you can tweak your connection to reduce the amount of buffering.
If you are still having trouble watching videos, there are a few things that you can do to minimize the effect of the stuttering.
With some video providers, you can start the video, pause it and wait.
This will allow the video to download a little way ahead of time so that you can let it catch up and watch for a longer uninterrupted period. Disabling IGMP Snooping will sometimes help reduce the buffering.
*Please note, 99% of all buffering issues are related to the internet speed and the data packet loss, which is something that we can do nothing about except changing the ISP.
You can also reduce the quality of the video. This will decrease the bandwidthdemand and increase the likelihood that the video will not stutter during playback.
Another optional approach would be downloading the entire video first before playing it. This may take longer, but it would likely ensure that you would be able to watch the entire video without interruption.
