How to Fix Buffering on Streaming Services

Step by step

1. Test your internet speed

   Open a web browser and navigate to fast.com or speedtest.net. Run the speed test and compare results to your plan's advertised speeds. Streaming 4K video requires at least 25 Mbps, 1080p needs 5 Mbps, and 720p requires 3 Mbps.

   Note: Test speed on the same device you're streaming on, not just your phone or laptop.

2. Close other apps and devices using bandwidth

   Pause downloads, close cloud backup services, and disconnect unused devices from your network. Check for automatic updates running on computers, gaming consoles, or smart home devices. Each active connection reduces available bandwidth for streaming.

   Note: Use your router's admin panel to see which devices are using the most bandwidth in real-time.

3. Switch to a wired ethernet connection

   Connect your streaming device directly to your router using an ethernet cable. This eliminates Wi-Fi interference and provides a more stable connection. If running cable isn't practical, move closer to your router and ensure no walls or large objects block the signal.

   Note: Powerline adapters can extend wired connections through your home's electrical wiring when running ethernet cables isn't feasible.

4. Lower the video quality settings

   Access your streaming app's settings and manually set video quality to 1080p or 720p instead of Auto or 4K. On Netflix, go to Account > Playback Settings. On YouTube, click the gear icon during playback and select Quality. This reduces bandwidth requirements immediately.

   Note: Most streaming services remember your quality preference, so you only need to change this setting once per app.

5. Restart your modem and router

   Unplug your modem for 30 seconds, then plug it back in and wait for full startup. Next, unplug your router for 30 seconds, plug it back in, and wait for all lights to stabilize. This clears network congestion and refreshes your internet connection.

   Note: Restart networking equipment during off-peak hours to avoid interrupting others' internet usage.

6. Update your streaming app and device

   Check for app updates in your device's app store and install any available updates. Also update your streaming device's system software through Settings > System Update or equivalent menu. Outdated software can cause compatibility issues that manifest as buffering.

   Note: Enable automatic updates to prevent future compatibility problems with streaming services.

7. Clear the app's cache and data

   On Android devices, go to Settings > Apps > [Streaming App] > Storage > Clear Cache. On smart TVs, uninstall and reinstall the streaming app. On computers, clear your browser cache or reinstall the desktop app. This removes corrupted temporary files that can slow streaming.

   Note: Clearing cache won't delete your login information, but clearing data will require you to sign in again.
