Governments and ISPs across the world monitor their users’ online activities. If found streaming copyrighted content on your Fire TV Stick, you could get into serious trouble. Currently, your IP is visible to everyone. I strongly recommend you to get a good FireStick VPN and hide your identity so that your movie viewing experience doesn’t take a bad turn.

I use ExpressVPN which is the fastest and most secure VPN in the industry. It is very easy to install on any device including Amazon Fire TV Stick. Also, it comes with a 30-day money-back guarantee. If you don’t like their service, you can always ask for a refund. ExpressVPN also has a special deal where you can get 3 months free and save 49% on annual plan.

Here are the reasons why you must use a VPN all the time.

What causes buffering on FireStick

There are a number of factors that can cause the buffering issue. Here are some of the most common reasons why buffering happens on FireStick:

  • 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 much 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 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  • Outdated Firestick OS: You may experience buffering issues on FireStick if it is running on an outdated OS

How to fix FireStick buffering issues

Now that we have looked at some of the most common factors that cause buffering on FireStick, let us find the solutions. Here they come.

1. Restart FireStick

If you can’t really put a finger on the exact reason causing the FireStick buffering issue, a trick, as simple as restarting, could be the solution.

2. Take Care of Internet Speed

You probably have a high-speed broadband and internet speed is not a problem for you. However, I would still recommend you to check the internet speed as the first troubleshooting step.

If it turns out you are actually getting desirable internet speed on FireStick, you will have taken this concern out of the way.

And, if it is the slow internet connection behind buffering issues, you can always reach out to your ISP to find out the reason or you might even get a new connection altogether.

Any speed above 10 Mbps is good enough for streaming in up to 1080p resolution

If you stream 4K videos, at least 20 Mbps is recommended.

Here’s how to check internet speed on Firestick

If your Firestick is not receiving the desired internet speed, here’s what you should do next-

Check and improve Wi-Fi signal strength

Signal strength plays a key role in a smooth streaming experience. The signal strength is stronger when the modem is near your FireStick and weaker when it is far.

Here is how you can check the signal strength on FireStick and act accordingly:

  • Go to the Settings from the FireStick home screen

Firestick buffering issue

  • Click Network on the next window

  • Highlight your Wi-Fi address/name
  • On the right, you will find the status under Signal Strength

Firestick buffering issue

If it says Very Good, you are getting proper Wi-Fi signals. If it says poor or weak, there is a problem.

Usually, the modem should be within 20-30 feet from the device for the best signal strength. If your modem is farther than this, you may want to consider buying a Wi-Fi Extender. As the name suggests, a Wi-Fi Extender expands the coverage area of your modem allowing it to be effective in a larger area.

You also need to make sure that there aren’t too many electrical devices near your modem that may cause interference with the signal.

And, if possible, place the modem a little higher up (6ft or higher) for better signal coverage.

Use Ethernet Cable for Wired Connection

use amazon ehternet adapter to prevent buffering on firestickA wired connection is usually much faster than the wireless connection. Firstly, it doesn’t have to rely on the proximity of the router from the device. The Ethernet wire is plugged directly into your FireStick.

Secondly, there are no obstacles between the router and the device. Many electrical, as well as certain mechanical obstacles, tend to weaken the Wi-Fi signal.

You can control or even fix buffering on FireStick with the wired connection. For the wired connectivity on FireStick, you can buy the Amazon Ethernet Adapter for Amazon Fire TV Devices from

The internet/LAN wire and the power cable from your FireStick power adapter will go into the Ethernet adapter. And then, a single cable from the Ethernet adapter will be plugged into your FireStick.

Note that you DO NOT need to buy the Ethernet Adapter if you are already getting substantial network speed through your Wi-Fi connection.

3. Use a VPN to prevent buffering

Recommended for better speed as well as the privacy

Internet throttling is a common practice among ISPs. Your internet provider may slow down your internet connection when streaming activities beyond a certain level are detected. As a result, you may experience buffering on FireStick.

Thankfully, this can be easily avoided by using a VPN for FireStick. A good  VPN will not only stop your ISP from throttling speed but will benefit in several ways such as:

  • Hide streaming activities from Government surveillance and ISP
  • Anonymous torrent downloads
  • Safeguards personal information from hackers
  • Unblock geo-restricted content (including Netflix, BBC iPlayer, Prime Video, Hulu, HBO, etc.)

In my experience, ExpressVPN is the best VPN for FireStick. It uses the best encryption technology and is the fastest VPN too.

Currently, ExpressVPN is offering a 49% discount on its yearly plan. On top of that, you get 3 months free with this plan. And, it also offers an unconditional 30-day money-back guarantee.

Here is what you can do to get ExpressVPN and avoid buffering on FireStick:

  • Click here to sign up for ExpressVPN
  • Once you have your ExpressVPN account, turn on your FireStick and select the search option in the top-left corner of the home screen

4. Clear up the FireStick RAM

FireStick has a RAM size – 1 GB on FireStick 2nd Gen and 1.5 GB on FireStick 4K. That is not quite a lot but enough for a streaming device. However, such small memory tends to get taken up rather too quickly.

Low RAM space is one of the culprits of the buffering you experience on FireStick. You will be surprised to know that some apps keep hogging the RAM even when you close them.

You can clear up the RAM space by simply closing the background applications. But, how would you find which apps are actually running in the background? Force closing all the installed apps individually is tedious and time-consuming.

Thankfully, there is an app you can use to find out the background applications and to close them. It is called the Background Apps and Process List. You can get this free app from the Amazon Store.

Here are the steps to download the Background Apps & Process List app and to use it close the background apps:

  • Go to the Search option from the FireStick home screen

  • Lookup for the Background Apps and Process List app and follow the on-screen instructions to install it

How to fix firestick buffering

  • Open the app. This prompt is displayed the first time.
  • Uncheck the option ‘Open app on boot’ if you don’t want the app to open automatically every time you restart your FireStick
  • Click Got it! button

  • You will see the list of all the apps running in the background. Click Close All Apps in the top-left corner

How to fix buffering on firestick

  • You will see the following window for the first app on the list. Go ahead and click Force Stop
  • When you are done, press the back button on the remote.

  • You will see the same options for the next app on the list. Click Force Stop again.
  • Keep repeating this until you have killed all the background apps

Note: Do not force close ExpressVPN (or any other VPN) running in the background. A VPN runs in the background while providing security. Force closing the VPN may cause you to lose the connectivity to the safe VPN server. VPN apps do not take a lot of space anyway.

5. Clear Cache/Data of Streaming App

Clearing the cache of the streaming apps may help you with the buffering on FireStick. Many users have reported that third-party apps like Cinema APK, Cyberflix TV, Ola TV, BeeTV, etc. performed better after they cleared their cache.

You may also clear the app data to completely reset the app to its default factory settings.

Here are the steps:

  • Go to the FireStick Settings from the home screen

  • Click Applications

You can do one of the following:

  • Clear data: It will clear all the app related data (including any sign-in information) and reset the app to the factory defaults. It will also clear the cache
  • Clear cache: If you just want to clear the cache and keep the remaining data intact, choose this option instead

6. Tweak your privacy settings

Amazon monitors and collects your data on the pretext of marketing and improvement. That is likely to compromise your privacy. But, that’s not just it.

To constantly monitor and collect your data, your FireStick OS must keep certain processes running in the background. This could slow down your FireStick and eventually cause buffering problems.

Here is how you can disable data monitoring and data collection:

  • Open Firestick Settings from the home screen

  • Click Preferences on the next screen

  • Click Privacy Settings

  • Turn OFF the following options: Device Usage Data and Collect App Usage Data

  • Now, press the back button one time and click Data Monitoring

7. Check and Update the FireStick OS

It is rare, but not unheard of. Outdated FireStick OS may be the reason why you are experiencing buffering issues.

Usually, your FireStick will update itself automatically whenever the new OS version is available. However, sometimes it may not.

So, here are the steps to check for and install OS updates:

  • Go to FireStick Settings

  • Open My Fire TV

8. Avoid FireStick Overheating

Overheating can cause device malfunction. It can also cause buffering or streaming issues on FireStick. Therefore, it is important that you keep your FireStick from overheating.

Here is our detailed guide on How to Fix FireStick Heating Problem.

While your FireStick can run for several hours without any problem, I recommend that you give it some rest from time to time.

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

If you think FireStick has overworked, unplug it from the power source and let it cool down for at least 30 minutes.

9. Use Real-Debrid for 3rd Party Apps

Real Debrid is a premium hoster that works with a wide range of third-party FireStick apps as well as Kodi addons.

Normally, the apps and add-ons connect to the public servers. Such servers will allow access to just about anyone. As a result, they have a high influx of traffic. This, in turn, causes server slowdown, downtime, and buffering issues on FireStick.

Real-Debrid, on the other hand, is a paid service. It restricts the server access to the premium users. Therefore, the streams from Real Debrid are much faster and reliable.

You can integrate Real-Debrid with almost all the popular apps like Cinema HD APK, CyberFlix TV, BeeTV, and more.
