Whether you're streaming on a computer, mobile phone, or TV, Netflix buffering can interrupt your streaming experience. Many users may wonder, "Why does Netflix keep buffering?" or "Why is Netflix so slow, even though my internet is fine?". In this article, we will walk you through the common causes of Netflix buffering and, more importantly, how to fix it—no matter what device you're using.
Part 1. Why Does Netflix Keep Buffering?
Netflix buffering can occur for various reasons, even if your internet seems to be working fine. Here are the most common causes:
Cause 1: Slow Internet Connection
A slow or unstable internet connection is often the main reason Netflix keeps buffering. For smooth streaming, Netflix recommends a minimum speed of 3 Mbps for HD and 15 Mbps for 4K Ultra HD. If your connection dips below these thresholds, buffering is likely to occur, especially during high-traffic hours. Check the table below for more detailed information.
| Video quality | Resolution | Recommended speed |
|---|---|---|
| High definition (HD) | 720p | 3 Mbps or higher |
| Full high definition (FHD) | 1080p | 5 Mbps or higher |
| Ultra-high definition (UHD) | 4K | 15 Mbps or higher |
Cause 2: Network Congestion
If multiple devices in your home are using the internet at the same time—whether for streaming, gaming, or downloading large files—your network can become congested. This congestion can result in slower speeds and Netflix lagging, leading to a less-than-ideal streaming experience.
Cause 3: Wi-Fi Signal Interference
A weak Wi-Fi signal can also be why Netflix keeps buffering but the internet is fine. If your streaming device is far from your router or there's interference from walls and other electronic devices, your connection may drop, leading to more buffering.
Cause 4: Accumulated Cache and Data
If Netflix keeps buffering but the rest of your devices work properly, it'd be the accumulated data on the Netflix app and the device you're using, which can take up too much storage and affect the speed of the software.
Part 2. How to Fix Netflix Constantly Buffering on Smart TV?
If your Netflix keeps buffering on a smart TV, try the following solutions to fix it:
Solution 1: Restart Your Device
A simple restart can often fix Netflix buffering issues. Turn off your TV, unplug it for 1 to 2 minutes, then turn it back on and launch Netflix again. This can clear up any temporary software glitches.
Solution 2: Sign out of Netflix
Sometimes logging out of your Netflix account and signing back in can resolve issues like Netflix lagging or slow loading times.
- Open the Menu on Netflix.
- Select Get Help, scroll down, and click on Sign out.

Part 3. How to Fix Netflix Buffering on Mobile Devices?
Mobile devices can also experience Netflix buffering, even with a strong internet connection. Here are ways to fix it on smartphones or tablets:
Solution 1. Quit All Recent Apps
Running multiple apps in the background can consume resources and lead to Netflix lagging. Quit all recent apps and only run Netflix for better performance. For both Android and iOS users, you can swipe up from the bottom, and swipe up on the app to quit it. After that, open Netflix again.
Solution 2. Restart Your Device
Just like on a TV, restarting your phone or tablet can fix temporary bugs that may cause Netflix buffering. Power off your device and wait a minute, then turn it back on.
Solution 3. Reset Your Network Settings
If Netflix keeps buffering on your mobile device, resetting your network settings can help. This will restore default network configurations, which can improve your connection.
For Android Users:
- Open the Settings app on your phone.
- Scroll down and tap either "General Management" or "System".
- Click the Reset option, and tap the words "Reset network settings".
- Wait for your phone to restart. When completed, open Netflix again.

Reinstalling the Netflix app can also fix issues. Uninstall the app from your phone or tablet, then install it again from the app store.
Solution 5. Reset the Netflix App
Another quick method to resolve Netflix buffering issues is to reset the Netflix app on your phone.
For Android Users:
