How to Fix Kodi Fire Stick Buffering Issue

While watching an HD movie, Kodi Fire Stick keeps giving a message that “Buffer full.”

With the growing popularity of streaming movies, the streams accessible through Kodi will have become less reliable. There are causes for Fire Stick buffering issue that are increasing the popularity of Kodi and unreliable movie links.

  • First, try installing a stock FireTV app. Then verify your Fire Stick still has the buffering issue.
  • Move your Fire Stick away from your TV. Because some TVs cause RF interference which would interfere with the Wi-Fi signal and it causes Fire Stick to buffer unnecessarily. Get high-speed HDMI Extension Cable.

Fix power supply issue

  • Try using an initial 2Amp Samsung Micro USB power supply. So that users can have a much better performance from the power supply.
  • Do not use a quick charge cable. It may damage Kodi Fire Stick.
  • Another common cause for buffering, when the device which you are using does not have that much power to process the stream and download the data. It occurs when using low-powered devices. To get rid of this, get a higher-powered device.
  • With Navi-X, we can eliminate Fire Stick buffering issues by downloading the video completely before we watch it.

ISP throttling issue

Internet provider could throttle your bandwidth. It means that they will limit your internet speed less than what you pay for. It causes unnecessary Kodi buffering. Use a VPN to bring your streaming activity without buffering.

To fix this, use a secure service like IPVanish to hide your streaming activity.

Fire sharing system fix

If you have Fire Stick buffering problems when playing videos from the local network, try NFS file sharing instead of SMB file sharing. Else try network attached storage (NAS) drive which links your network and allows all connected devices to get accessed your video files.

Wi-Fi Analyzer

If you know about software Wi-Fi analyzer to see videos which are showing with less congestion, set your router to use interference free channels.

  • Get a WiPry-Pro iPhone/iPad spectrum analyzer to show Wi-Fi interference.
  • Check out the list of free Wi-Fi surveying tools.

Try low-quality stream

  • You could also try a gnarly Hi-power Wi-Fi router or DOCSIS 3.0 cable modem. Make sure the device should be compatible with your internet service provider.
  • On the other side, if you have fast internet connection, you can stream 4K movies from Amazon and Netflix using a 4K TV site.

Due to overheating

Since the Fire Stick has lots of power, it will get hot. Try using a small USB-powered mini desktop fan beside it, so it cools down. Cool electronic parts work better than hot parts.

Disk space fix
