Amazon FireStick is one of the most popular streaming devices worldwide. It is incredibly easy to set up and use. It supports tons of awesome apps from the Amazon Store as well as several third-party apps. All in all, FireStick makes for an amazing streaming experience.

However, many users also experience buffering issues with their FireStick. The percentage of such users is small. However, given that millions of users have FireStick, that small percent amounts to a considerable number.

If your FireStick keeps buffering all the time, this article discusses various possible reasons and solutions.

 

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• Outdated FireStick OS: You may experience buffering issues on FireStick if it is running on an outdated OS

How to Stop Buffering on FireStick

The following are the solutions to stop buffering on FireStick:

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 your device, could be the solution.

In fact, restarting is one of the most basic troubleshooting methods and it should be one of the first ones to try. It can solve many problems.

Here are the steps:

• Go to FireStick Settings

• Click My Fire TV

• Click Restart

• Click Restart to confirm

2. Take Care of Internet Speed

You probably have 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 Amazon 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.

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 Amazon FireStick and act accordingly:

• Go to the Settings from the FireStick home screen

• Click Network on the next window

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

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

A wired connection is usually much faster than a 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 Amazon FireStick.

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

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 Amazon.com.

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 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 service 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, PremiumVPN is the best VPN for FireStick. It uses the best encryption technology and is the fastest VPN too.

 

4. Clear Up FireStick RAM

Amazon FireStick has a RAM size – 1 GB on FireStick 2^nd 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 to close the background apps:

• Go to the FIND option from the FireStick home screen and click Search

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

• 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

• 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 PremiumVPN (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 connectivity to the safe VPN server. VPN apps do not take a lot of space anyway.

5. Clear Cache/Data of Streaming Apps

Clearing the cache of the streaming apps may help you with the buffering on FireStick. Many users have reported that third-party apps 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

• Open Manage Installed Applications

• You must now see this list of the installed apps
• Go ahead and click the streaming app with buffering issues

• You will find the app data and cache data information on the right section of this window

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

• Turn OFF 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

• Click About

• Click Check for Updates

• Wait for a few seconds. Your FireStick will tell you whether any updates are needed or if your device is already up to date

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.
