To understand buffering, you must first understand that an IPTV stream isn’t sent directly to a device as is. Instead, the IPTV servers issue data “packets.”
These packets are why you can keep streaming for a few seconds after losing your internet connection.
If there’s a delay in sending, receiving, or processing those data packets, it causes your device to pause while it waits for more packets.
The process is called buffering. So, is there a way to fix IPTV buffering problems? That depends on the cause. There are some things you can do to fix the problem, but some are out of your control.
