As an avid Fire TV Cube user, I know first-hand how frustrating and annoying it can be when your device starts to lag. I recently had some issues with my Fire TV Cube and I’m here to share the causes and how I fixed it, as well as some additional tips and tricks I discovered during my research.
A few of those could be low bandwidth, outdated apps, or maybe even a glitch. In some cases, you just need to restart the Amazon device.

Causes of Laggy Fire TV Cube
Nothing worse than having to repeat your commands to your Fire TV Cube. Now, before we get into why this is happening, it’s worth noting that there are two versions of this device. The first-gen and second-gen Fire TV Cube.
Both are vastly different in their operation. The first one is more prone to lagging since it has a measly four-core CPU. Meanwhile, the second-gen offers a Hexa-core CPU, which means it has better performance and UI.
Having said that, you have better chances of fixing the lagging issue if you have a second-gen Fire TV Cube than a first-gen one.
With that out of the way, here are the most common reasons why your Fire TV Cube is lagging.
Reason 1: Lack of Updating
Updating the latest version of any app is crucial. Apart from design and UI improvements, the updated version could also have bug fixes that may be the root cause of lagging.
In the Fire TV Cube’s case, you may need to check whether the firmware is updated or not. Firmware is basically a low-level software that directly interferes with the hardware.
Reason 2: Unstable Internet Connection
Lagging’s number one enemy is an unstable internet connection. Before blaming the lag on anything, you need to check whether your Wi-Fi is working on any other device like your phone.
To double-check whether a low bandwidth is the culprit, you can go to speedtest.net to find out your ping speed. If it’s higher than 20ms, then it’s too slow.
Reason 3: Cable Issue
Unlike the Firestick TV, the Fire TV Cube doesn’t have a built-in HDMI port. You need to get a separate one to connect the Amazon device to your TV.
Now, some cables might not fit too loosely, which hinders the Fire Cube TV’s connectivity. That being said, if your cable looks torn, you might have an exposed wire. In which case, the cable might need to be replaced.
Reason 4: Overheating Hardware
The strongest indicator of overheating hardware is your CPU throttling in the Fire TV Cube. The dynamic frequency scaling will, in turn, cause lagging.
Reason 5: Freezing Issues
If you have a second-gen Fire TV Cube, you might run up on a freezing issue. That’s mainly because this version has a 4k Dolby Vision. This feature eats up a lot of power, which can make it more vulnerable to lagging issues.
How to Fix Laggy Fire TV Cube
Now that you know why the Fire TV Cube could be lagging, it’s time to try some fixes. If you’ve already tried all of these fixes to no avail, then we highly recommend contacting Amazon Support to help you out.
Without further ado, here’s how to fix a laggy Fire TV Cube.
Check Your Internet Connection
If you’re dealing with a Wi-Fi connection issue, then you can start by turning the router on and off. Make sure to wait at least five minutes before turning it back on.
If it’s still not working, try to switch to a wider 5GHz bandwidth. This is possible if you have a dual-band Wi-Fi router supporting both 2.4GHz and 5GHz. Alternatively, you can connect your ethernet cable for a speedier internet.
Restart the Fire TV Cube
It can mostly come down to a regular power cycle to fix the lagging problem. There are a couple of methods on how you can restart the Fire TV Cube.
The first one involves physically unplugging the device from its socket. Afterward, wait five minutes, plug the Fire TV Cube back in, and turn it on.
On the other hand, you can restart it by going to the “Home” button. Next, access your “Settings” tab and select “My Fire TV.” Finally, choose the “Restart” option.
Update the Fire TV Cube System
To check for any updates that’ll fix the lag, navigate to the “Settings” on your Fire TV Cube. Click on “My Fire TV” followed by “About.” Lastly, select “Check for System Update.”
Adjust Your Fire TV Cube Settings
If your internet can’t keep up with the resolution, it’s going to hit a lag. You can adjust the signal resolution by holding the “Up” and “Rewind” buttons from the Fire TV Cube remote for five seconds.
In the prompt that’ll appear, scroll down until you see the resolution you need. Afterward, click on “Use Current Resolution.”
To Conclude
Why is your Fire TV Cube Laggy? To summarize, it could be an issue of slow internet, lack of updating, or a hardware issue.
Luckily, the fixes are simple since they mostly involve power cycling your router or Fire TV Cube. May you never experience another lag again.
