How to fix IPTV buffering on Firestick?

There are various reasons for IPTV buffering problems. Here are some of the most common reasons why FireStick buffers:

  • Slow internet connection: It is recommended that you have at least 10 Mbps for 1080p and 20 Mbps for 4K streaming. If your internet connection is slow, you will experience buffering issues
  • ISP Throttling: Your ISP might slow down your connection speed from time to time if they detect too many streaming activities
  • Modem far from FireStick: If your FireStick is placed too far from your Wi-Fi modem, your signal strength will be weak and will cause buffering issues
  • Running low on RAM: It is not uncommon for FireStick to run out of RAM. There may be many unnecessary apps running in the background
  • Running low on storage: Again, it is common among FireStick users. The device has only 8GB of space, a lot of which is already used up by the OS
  • FireStick overheating: If your FireStick is overheating, it is likely to cause buffering issues
  • Outdated FireStick OS: You may experience buffering issues on FireStick if it is running on an outdated OS
  •  Problems with IPTV servers: many poor-quality IPTVs often lag, contact your provider or choose a higher-quality IPTV subscription service                            

Use Ethernet Cable for Wired Connection

A wired connection is usually much faster than a wireless connection. Firstly, it doesn’t have to rely on the proximity of the router to the device. The Ethernet wire is plugged directly into your Amazon FireStick.

Secondly, there are obstacles between the router and the device. Many electrical and certain mechanical obstacles can weaken the Wi-Fi signal. Using a wired connection will drastically reduce interference and make the network faster!

You can control or even stop buffering on FireStick with a wired connection. To use a wired connection on FireStick, you can buy the Amazon Ethernet Adapter for Amazon Fire TV Devices from

Don’t leave it switched on overnight. Unplug it from the power source.

Update Firestick OS and applications
