How to stop the Curiosity Stream app from buffering

Method 1: Restart the Curiosity Stream app

It is a good idea to restart the Curiosity Stream app if you are experiencing buffer issues.

By restarting the Curiosity Stream app, you give the opportunity for any updates to be correctly installed and establish a new connection with the Curiosity Stream servers.

Method 2: Sign out of the Curiosity Stream app

Another potential quick fix to the Curiosity Stream buffering problem is to sign out of your account.

By signing out of your Curiosity Stream account before you return and log in, you may resolve any account-related issues with are causing the buffering problems to occur.

Method 3: Restart your Playback Source Device

To access the Curiosity Stream app, you will be using a playback device to access the app.

The most common playback devices for the Curiosity Stream app are:

  • Smart TVs
  • Content Devices such as Curiosity Stream, Firestick, or Roku
  • Games Consoles such as PlayStation and XBOX
  • A PC or MacBook Laptop

The universal recommendation for these devices and the first step in trying to eliminate the Curiosity Stream app freezing issues is to perform a power cycle of these systems.

To perform a power cycle of the devices, simply unplug them for 60 seconds before plugging them back in.

This restart allows any updates that have been downloaded in the background to successfully install and start, and it also clears the system cache.

Clearing the system cache and any lingering apps running in RAM can help in reducing the buffering of the Curiosity Stream app.

By reducing the number of apps running in the background, you give the Curiosity Stream app the best performance.

Method 4: Reset your Router

This is one of the oldest tricks in the book, but it is definitely effective in reducing the buffering on the Curiosity Stream app.

How do I reset my router?

The easiest way to reset your router is to simply unplug it from the wall socket for 30 seconds before plugging it back in.

Unplug your router, stop Curiosity stream from buffering
Restarting your Router almost always improves your bandwidth capacity to be able to effectively play content.

This action will “power-cycle” your router and provide more bandwidth to increase your ability to play content faster on the Curiosity Stream app.

Why does resetting your router reduce the Curiosity Stream app buffering?

Think of all the devices that are and have been connected to the router. I’m sure that in today’s digital world that quite a few devices are connected to the router.

Your router is like a mini-PC and will slow down as more tasks are added.

Having all of those devices connected will reduce the bandwidth available to the Curiosity Stream app and subsequently throttle your download speed, which in turn creates buffering.

Method 5: Update your Curiosity Stream app

If you are playing Curiosity Stream using a device such as a Firestick, Roku or smart TV then I would recommend that you update the app if possible.

Method 6: Disconnect other devices in your home from the internet

If you cannot reset your router for any reason, I would try and disconnect none essential devices from the internet.

Is someone in your home watching Netflix? What about your phone? Is someone downloading games or apps on XBOX?

Every device that you can disconnect from your internet connection will help in stopping the Curiosity Stream app buffering issues.

Method 7: Close any apps that are running

If you have followed our first step of restarting your playback device, then this step would have been completed for you, otherwise please continue to close any running apps.

How does having open apps cause the Curiosity Stream app to buffer?

Imagine your internet connection to your  Curiosity Stream application like an artery in your body. The more games and apps that are running are like blockages in your arteries, sorry for the weird analogy!

Those blockages impede your ability to play content faster, and then that results in buffering occurring when watching the Curiosity Stream app.

Method 8: Decrease Video Quality

Check in the Curiosity Stream app options when watching content if there is a toggle for video quality.

The higher quality content that you play, the more likely it is that buffering will occur.

Try and decrease the video quality, especially if you have the quality set to 4K.

Method 9: Update your device software/firmware before downloading

Whether you are using a TV, Content Device, or Games console, updating your firmware or software to the latest version can help in preventing issues from arising over time.

Sometimes updates can be missed, or an installation can be interrupted and cause issues with your playback device.

Old firmware or a partial firmware installation could cause the Curiosity Stream app to buffer.

Ensuring that you have the latest software on your devices also gives you access to new apps and an improved viewing experience.

Method 10: Use an Ethernet cable rather than Wi-Fi

It is almost always true that when you use an Ethernet (Wired Connection) rather than Wi-Fi, you will get a better download speed.

Wired connections transmit data quicker and with less interference. There are also fewer variables that can hinder the quality of connection.

Wi-Fi connections are slower and generally have a slower response time.

The distance from your playback device along with the walls, floor, and ceilings can all deteriorate the quality of your internet connection, causing the Curiosity Stream app buffering issues.

I always use a wired connection when it is available, and you should too!

Method 12: Disable any Ad blockers or VPNs

VPNs and Ad blockers can negatively affect the playback performance of the Curiosity Stream app.

Your connection to a VPN will always limit the speed at which you can play content.

We understand that using a VPN can be a sensible choice, especially due to privacy concerns.

Unfortunately, by using a VPN, you are creating another dependency that can cause Curiosity Stream to buffer if there are any problems or limited speed.

Method 12: Upgrade your Internet Connection

Not everyone has access to high download speed through their ISP (Internet Service Provider), but for those that do, consider upgrading your internet connection.

It is pretty straightforward that a 100mbps connection will have a slower download rate than a 1gbps connection.

Method 13: Upgrade your Router

If you have consistently upgraded your internet speed through your ISP but are still using an older router, you may wish to check what the maximum download speed of your router is.

It’s all good having a 1gbps connection, but if your router can only download at 100mbps, then you’ve got yourself a massive bottleneck and a solid explanation as to why the Curiosity Stream app is buffering.

Method 14: Contact Curiosity Stream Support

If you have tried all the tips above and nothing has worked, then you can contact Curiosity Stream app support for further assistance.


If you have followed the guide, then you would have been successful in reducing the buffering of the Curiosity Stream app on your content device.

We hope that you enjoy buffer-free playback.
