Are you fed up with buffering issues or lag? If so then you have come to the right place! This is the ultimate Amazon Firestick Buffering Guide to speed up your Fire TV Stick.

This is the ultimate and only guide you will ever need to help identify & fix your buffering issues.

Watch the video above or check out the hints and tips below.

What can cause buffering and how to fix it?

1) Check your internet speed

It is recommended that you have a download speed of at least 10Mbps for streaming in 1080p & at least 25Mbps for streaming in 4K. Speeds that are slower than this are more than likely the cause of your buffering issues.

You can easily run a speed test for free by searching for SPEED TEST on your Amazon device or in a web browser on any other device. Run the speed test 3 times to give an average result & this will also help identify if you are getting a consistent speed as this is also important.

If you are getting slow speeds, there are a few things to consider to improve your speed.

– Are you sharing the internet with others in your household & are they also streaming content/playing games & taking up a lot of bandwidth?

– Are you connected via WiFi? If you are, you can try connecting via ethernet. For a recommended ethernet cable, try these:

Buy from Amazon US

Buy from Amazon UK

– You could also try checking if you are connected to the 2.4Ghz or 5Ghz range. So go to your network settings and have a look at what options you have available. Higher bandwidths like 5GHz WiFi provide faster data connections than 2.4GHz

2) Some Internet Service Providers may throttle your speed

Your ISP could be throttling your speed if they feel you are using too much bandwidth. Alternatively, there may be a data cap or restriction with your service. If you have a data cap, you will get a certain speed until you hit that limit, then they will throttle you down.

There are several ways you can check if your ISP is throttling.

– The easiest way of finding out is to run a speed test. Then connect to a VPN and run a speed test again. If your speeds are significantly faster with a VPN, it’s highly likely your ISP is throttling your speeds.

– You can run a daily speed test & see if the results are similar to what download speeds you are paying for. If not, there could be an interference problem or get in touch with your ISP to find out if they are capping you.

If you find that it is your ISP causing your issues, consider switching provider.

3) Your modem or router could be too far away from your device

For some handy hints on the best location for your router, click on the tutorial below as there are a lot of important things you should consider when choosing the best place for your router.


You should also do a re-set of your router on a monthly basis. As you might already know with a pc or other electronic device, most crashes or bugs can be fixed with a simple re-boot. Just un-plug it from the mains, wait 30 seconds & plug it back in. This really can make a big difference.

It is important to wait those 30 seconds because you may have noticed that sometimes when unplugging an electrical item, the power light stays on for a few seconds. This is because most items have tiny batteries that store just enough energy to keep a memory chip running for a few seconds. Waiting 30 seconds just gives it time to make sure the battery is drained & fully discharged, ensuring all bits of memory are cleared & ensures that all settings are re-set.

4) Not enough RAM or system resources

You can try clearing the RAM, closing background applications and clearing cache. All of these things can cause your device to run slow or affect streaming quality.

To clear your RAM

– Try installing Garbage Cleaner and RAM booster from the Amazon app store. Or, if you are using an Android device, try Avast Cleanup.

To close background applications

– On the Firestick, you can close applications manually by going to Settings > Applications > Manage Installed Applications > Then clicking on each app within the list and choosing Force Close from the menu. Or you can install an app from the Amazon app store called Background Applications & Processes List.

To clear cache

– On the Firestick, there are currently no automated proccesses or apps you can use to clear cache. This has to be done manually for each application by going to Settings > Applications > Manage Installed Applications > Then clicking on each app within the list and choosing Clear Cache from the menu.

5) Reboot your Firestick

Sometimes, just like with your router, your Firestick or other device may just need a reboot to fix any issues. Unplug it, disconnect the power, wait 30 seconds then plug it all back in.

6) Adjust settings to free up memory

If you are using a firestick, you can adjust some settings to turn off processes that continuously run in the background to free up memory.

Click the link below for a tutorial.

7) Check for updates

Check regularly for updates for your device to ensure you are up to date with the latest firmware.

– To check for updates go to Settings > My fire TV > About > Check for Updates

8) Don’t overload your device

On your firestick, you need at least 1MB of free space in order to keep things running smoothly.

Check your storage & if you’re running low on space:

– Delete apps you don’t need anymore or take a look at the link below for a full tutorial & hints & tips on what to do if you are running low on storage.

9) Use Real-Debrid

Real-Debrid is a premium service that allows its users to have access to premium download links at high speeds which can make a huge difference if you have frequent buffering. Many users have commented on how they wish they would have found out about Real-Debrid sooner as the difference in streaming is amazing!

– Take a look at the link below for a full tutorial & detailed guide on what Real-Debrid is, how to get it and how to use it.

10) Are you using a VPN?

Are you running a VPN & is your VPN giving you slower speeds? The easiest way of finding out is to run a speed test with your VPN disconnected. Then connect to a VPN and run a speed test again. If your speeds are significantly slower with a VPN try these tips below.

– Make sure you are connecting to the server that is closest to your location. The distance between you and the VPN server can be one of the main causes of slow speeds when connecting to your VPN.

– You can also try adjusting protocols & settings. Check out the video tutorial below. Although this video shows how to adjust Settings within IP Vanish, these Settings are pretty much universal & can be applied to almost any other VPN.

– You can also think about either contacting the customer support of your VPN provider or switching provider. Most VPNs  you can now try out risk free as if you don’t like their service for whatever reason, most services offer a 30-day money back guarantee.

– If you are using a free VPN, in my experience, Proton VPN gives the best speeds for a free VPN, but to get even better speeds with a VPN, I would recommend switching to a paid one. Check out the VPN section for some great deals and offers.
