Netflix Keeps Buffering? Here's How to Fix It

Netflix often buffers and gets stuck on loading. Your device might not be freezing entirely, but the video can still freeze up. This issue can pop up on Smart TVs, mobile phones, streaming devices, browsers, and gaming consoles. The causes are different. It can be slow Wi-Fi, unstable network connection, device issues, or Netflix settings.

The good news is that most Netflix buffering problems can be fixed in a few simple steps. In this guide, you will learn the most effective ways to stop Netflix buffering and get smooth playback again on any device.

Part 1. Why Does Netflix Keep Buffering?

Netflix buffering happens when video data cannot download fast enough to match playback speed. The video needs a steady flow of data. When that flow breaks or slows down, you will see loading, pauses, or low-quality playback.

Here are the main reasons why Netflix keeps buffering:

1. Not enough internet speed

Your internet may be too slow for the video quality you are trying to watch. Netflix suggests different speeds for different quality levels. But in real homes, you often need more speed because many devices share the same network.

In our test, we compared Netflix's official numbers with real-world use in a home with multiple devices:

Minimum speed needs for smooth playback:

2. Network Crowding

Even if you pay for fast internet, sharing the connection makes it slow. If someone else in your house is playing online games, downloading big files, or saving photos to the cloud, there is less "room" for your Netflix stream.

3. ISP Throttling and Nighttime Lag

Some Internet Service Providers (ISPs) use "Deep Packet Inspection" to see that you are watching video. They might intentionally slow video traffic during busy hours to save money or manage their network. This is sometimes called ISP throttling. This is why you might notice Netflix buffers at night even if your speed test looks normal during the day.

4. Device Overload

Streaming tools like Smart TVs and Fire Sticks are just small computers. Over time, they run too many hidden tasks in the background. When their RAM (Random Access Memory) is full, they cannot process high-quality video smoothly. Using an old version of the Netflix app or old system software also makes this worse.

5. App Cache and System Data Problems

Netflix stores temporary files (cache) to load faster. If these files get "broken" or corrupted, the app will get stuck on the loading screen. Also, if your device uses a slow or unstable DNS (Domain Name System), it may take longer to find Netflix servers. This delay can also cause buffering.

Part 2. Quick Fixes to Stop Netflix Buffering Immediately

If you want a Netflix buffering fix fast, try these simple steps first. These solutions solve 90% of streaming problems in just a few minutes.

Fix 1. Restart the Device

Restarting clears out "trash" files and gives the Netflix app a fresh start. Here's how to restart your smart TVs, streaming sticks, mobile phones, and computers:

Fix 2. Netflix Server Check

Go to a site like DownDetector or search “Is Netflix down” on Google. If many users report issues, the Netflix servers may be having problems. In this case, you just need to wait.

Fix 3. Check Internet Speed and Stability

Netflix has its own speed test tool to see if your connection is strong enough. Simply go to Fast.com in a browser. Let it run and check your download speed. As we mentioned in Part 1, try to have at least 25 Mbps for a perfect experience.

Fix 4. Lower Your Video Quality

You can easily change this on the Netflix website, and it will apply to all devices under your profile. When you use the mobile app, tweak your Cellular Data Usage. This also allows Netflix to run at a lower resolution. Here's how:

Fix 5. Disable VPN or Proxy Connection

If you are using a VPN, turn it off. Netflix often blocks or slows down traffic from VPNs, which causes buffering.

Fix 6. Sign Out and Re-login to Netflix

Fix 7. Update Netflix App Version

1. 01

   Go to the App Store (iPhone), Google Play Store (Android), or your TV's App Gallery.

2. 02

   Search for Netflix.

3. 03

   If you see an "Update" button, click it to install the latest version.

Part 3. Fix Netflix Buffering on Different Devices

If the quick fixes above still do not solve the Netflix buffering issue, you can try more advanced solutions based on your device.

However, if you want a solution that always works 100%, you can skip to Part 4. We will show you how to download Netflix videos as MP4/MKV files. This way, you can watch your favorite shows offline on any device without any loading circles or lag.

3.1 How to Fix Netflix Buffering on Smart TVs

If Netflix keeps buffering or loading on your Smart TV, the problem is often caused by weak Wi-Fi, slow network setup, or app cache issues. Try these Smart TV fixes to improve streaming stability.

Method 1: Switch to a Wired Ethernet Connection

Most Smart TVs have a "Fast Ethernet" port that can handle up to 100 Mbps, which is plenty for Netflix. What you need is an Ethernet cable (Cat5e or Cat6). Here's how to set it up:

1. 01

   Plug one end of the cable into your router's LAN port.

2. 02

   Plug the other end into the LAN port on the back of your TV.

3. 03

   Go to your TV Settings > Network.

4. 04

   Change connection from Wireless to Wired (Ethernet).

Method 2: Change DNS Settings

If your internet works fine but Netflix is still slow, changing DNS can help. You can speed this up by using a public DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1).

Example for Samsung Smart TVs (other brands are similar):

1. 01

   Go to Settings from the main menu.

2. 02

   Select General > Network > IP Settings.

3. 03

   Find DNS Setting and choose Enter manually.

4. 04

   Type in 8.8.8.8 or 1.1.1.1. Open Netflix again to see if it plays without lag.

Method 3: Clear the Netflix App Cache

If Netflix is slow but other apps like YouTube or Disney+ work fine, the problem is likely the Netflix cache. Here's a quick guide on how to clear the Netflix cache on Samsung, Sony/Android, and LG TVs:

3.2 How to Fix Netflix Buffering on Mobile

If you are using the latest version of the Netflix app and your internet connection is working fine, but Netflix still keeps freezing while playing videos, you can try the following solutions to fix the problem and get smooth playback again.

Method 1: Close Background Apps and Downloads

If your phone is busy with social media or games, Netflix might struggle to play smoothly. For iPhone users, just swipe up from the bottom of the screen and close all the apps. If you're on Android, hit the Square icon or III button at the bottom, then tap "Close All" to stop everything running in the background.

Also, avoid downloading anything on Netflix while you're streaming.

Method 2: Clear Netflix App Cache (Android Only)

iPhone users need to reinstall the app to clear the cache, but Android users can do it in the settings to fix data errors.

1. 01

   Open your phone Settings and go to Apps (or Manage Apps).

2. 02

   Find and tap on Netflix.

3. 03

   Tap Storage.

4. 04

   Select Clear Cache. (Note: Do not click "Clear Data" unless you want to sign in again).

Method 3: Toggle Airplane Mode On and Off

This method forces your device to reconnect to Wi-Fi or mobile data and refresh the network signal.

1. 01

   Swipe down to open the Control Center (iPhone) or Quick Settings (Android).

2. 02

   Tap the Airplane icon to turn it on.

3. 03

   Wait for 10 seconds.

4. 04

   Tap the icon again to turn it off. Your phone will now search for the strongest available signal.

3.3 How to Fix Netflix Buffering on Streaming Devices

If your Roku, Fire Stick, or Apple TV is stuck on a loading screen, the problem is often a "clogged" app or a bad connection. Use these device-specific steps to stop Netflix buffering for good.

Method 1: Reinstall the Netflix App

Method 2: Reset Network Connection to Default

If other apps are also lagging, your device might have a weak link to your Wi-Fi. Note: You will need to type in your Wi-Fi password again after this.

Method 3: Clear Device System Cache (Free Up RAM)

Clearing the cache gives your device more "brain power" to play high-quality video without stuttering.

3.4 How to Fix Netflix Buffering on Browser

If you are watching Netflix on Chrome, Edge, Safari, or Firefox and the video keeps stopping, the problem is usually caused by "heavy" browser data or conflicting plugins. Use these steps to fix Netflix buffering on your computer:

Method 1: Clear Netflix Cookies and Cache

When your browser stores too many temporary files, the Netflix player can slow down or freeze. Clearing this data gives the player a "clean pipe" to stream video.

Method 2: Disable Browser Extensions

Extensions like ad blockers, VPNs, or privacy tools can block Netflix scripts and cause buffering.

Refresh your Netflix tab. If the buffering stops, turn your extensions back on one by one to find the one causing the trouble.

Method 3: Use Incognito (Private) Mode

Incognito mode opens a window without extensions and with a fresh set of cookies. It is the fastest way to check if your browser settings are the problem.

Log in to Netflix in the new private window. If the video plays perfectly here, you know that a corrupted cookie or a bad extension in your normal window is the reason why Netflix keeps buffering.

3.5 How to Fix Netflix Buffering on Gaming Consoles

Gaming consoles like the PS5 and Xbox are powerful, but "data traffic jams" can still cause Netflix buffering issues.

Method 1: Manual DNS Configuration

Manual DNS can reduce loading time and improve connection to Netflix servers.

Method 2: Rebuild Database (PlayStation Only)

This reorganizes system storage and fixes broken or messy data that can slow Netflix playback. It will not delete your games.

1. 01

   Turn off your PS5 completely. Hold the Power button until the second beep (7 seconds).

2. 02

   Connect your controller with a USB cable and press the PS button.

3. 03

   Choose Option 5: Rebuild Database.

4. 04

   Wait 5–15 minutes for the console to restart.

Method 3: Clear Alternate MAC Address (Xbox)

If you have ever used your Xbox on a hotel or school network, old settings might be "confusing" your home Wi-Fi. This causes the Netflix buffering problem.

1. 01

   Press the Xbox button and go to Settings > General > Network settings.

2. 02

   Select Advanced settings > Alternate MAC address.


3. 03

   Select Clear and then Restart.
