12 Fixes that Resolve Firestick Buffering Issues – Guaranteed [Updated]

Buffering issues can turn your streaming paradise into a buffering nightmare! Doesn’t matter if you’re a newbie with a Firestick or an experienced user, you’ll at some point in time face buffering issues with your Fire TV stick device.

Nevertheless, in this comprehensive guide, we’ll discuss why Firestick keeps buffering and how can these issues be resolved.

Why does my Firestick keep buffering?

Even if everything works perfectly, we won’t notice the constant buffering when watching a streaming video. But you start noticing the lags and start wondering why does my firestick keep freezing.

To play back a video, the Firestick first downloads it into a particular section of memory called a buffer. A video must be paused while more data is downloaded and processed if it is being played back quicker than added to the buffer. What we call “buffering” describes this bottleneck, which can make watching a live stream unpleasant for those watching.

Buffering on an Amazon Fire TV Stick or Amazon Fire TV Cube can be caused by many different problems, so figuring out the root cause is the first step.

The majority of times when a Firestick is buffering, it is because of a slow internet connection. To buffer standard definition (SD) video, you’ll need roughly 5 Mbps, 10 Mbps for high definition (HD), and 25 Mbps for 4K.

If your home network can support the video quality you’re after, you may check your speed using a service like Fast.com or Speedtest.net on your mobile device or computer.

Buffering on your Firestick can be caused by several factors. Understanding these factors can help you troubleshoot and resolve the issue effectively:

  • Streaming content requires significant bandwidth, especially in high definition (HD) or 4K. If your internet plan doesn’t provide sufficient speed, buffering can occur.
  • Even if you have a fast internet plan, fluctuations in speed, known as latency or jitter, can lead to buffering. Your connection might be fast one moment and slow the next.
  • During peak usage times, such as evenings when many people are streaming or gaming, network congestion can slow down your connection and be the reason why your firestick keeps freezing.
  • Distance from Router: If your Firestick is far from your Wi-Fi router or has to go through multiple walls and obstacles, the signal strength may weaken, causing buffering.
  • Interference: Other electronic devices, walls, and neighboring Wi-Fi networks can interfere with your Wi-Fi signal.
  • Running multiple apps or processes in the background on your Firestick can consume its resources, causing it to struggle with streaming, which leads to buffering.
  • Streaming content in higher resolutions like 4K or HD requires a faster and more stable internet connection. If your connection can’t keep up, buffering will happen.

How to stop buffering on Firestick

1.   Reboot Firestick

A simple reboot often works wonders if your Firestick is experiencing buffering issues.

To do this, follow these steps:

  1. Go to the “Settings” menu on your Firestick.
  • Select “Device” or “My Fire TV” (depending on your Firestick model).
  • Scroll down again and choose “Restart.”

This process will refresh your Firestick, clear its memory, and close any background apps that may consume resources. It’s a quick and effective way to resolve buffering problems caused by temporary glitches.

2.   Improve wi-fi signal

For 1080p streaming, you’ll need at least 10Mbps; for 4K, you’ll need at least 20Mbps. Buffering problems occur while using a sluggish internet connection.

Follow these steps to check the Fire TV Stick’s connection status and network speeds:

  1. Go to the Settings menu and click on Network.
  • Choose your current network.
  • You may inspect the current Wi-Fi frequency from this menu, check the connection’s status, and run a speed test.

3.   Use an ethernet cable.

For the most stable and reliable connection, connecting your Firestick directly to your router using an Ethernet cable is highly recommended. This eliminates potential Wi-Fi-related buffering issues and ensures a fast and consistent data transfer.

4.   Use a VPN

A VPN can be a smart way to mitigate buffering issues on your Firestick and enhance your streaming experience. Firstly, it can help in reducing throttling imposed by some ISPs. These ISPs may intentionally slow down your connection, known as throttling, especially when they detect high data usage from streaming services.

By encrypting your internet traffic, a VPN makes it challenging for your ISP to identify your streaming activities, preserving your connection speed.

It will also enhance your bandwidth by routing your traffic through its server; hence, due to lesser load and unlimited bandwidth, you’ll be able to enjoy seamless streaming.

Additionally, a VPN can be a handy tool for bypassing geo-restrictions. It achieves this by masking your IP address and making it appear as if you’re connecting from a different location. This can be particularly beneficial when accessing content unavailable in your region.

Therefore, get a reliable VPN like AstrillVPN, which offers many servers and top-notch military-grade encryption. Additionally, AstrillVPN provides excellent VPN protocols tailored for online streamers.
