Fix Zoom Lag by Getting Fast Internet

The most obvious choice is to use a high-speed internet connection. Ensure that you have internet speeds of at least 20-30 Mbps to get a flawless Zoom call experience. You can use the Speedtest tool to see what speeds you are getting.

Most modern WiFi routers come with 2.4GHz and 5.0GHz support. Always connect with the 5.0GHz as this will give you the best possible internet speeds.

Zoom Backgrounds

If you haven’t cleaned up your room and you have an important meeting coming up, the app allows you to set a custom background. However, using this feature lowers the video resolution to maintain CPU bandwidth. We suggest cleaning the room and not using this background feature if you want a lag-free call experience.

To turn this feature off, follow the steps below:

Step-1: Open the Zoom app.

Microphone and Video Settings

When you are on long Zoom calls you can save bandwidth for your connection by muting the microphone when you are not talking. This has two advantages:

  •  The other people in the call won’t hear any background noise from your end.
  •  Zoom will not use its resources to try and catch your voice.

To do this, click on the microphone icon to mute or use the shortcut keys Ctrl + D to mute the mic. You can also switch off the video and use a profile picture instead to ensure you get a lag-free call experience.

Zoom Apps

You can enhance Zoom app functionalities by using the Zoom app marketplace. If you are using a lot of third-party apps, they may be the reason for the lag you are experiencing. To fix this, disable the apps that you no longer use.

Step-1: Sign in to Zoom marketplace. [Use your Zoom app credentials to sign in]

Step-2: Click on Manage at the top of the screen.
