Sometimes the audio or video in Zoom becomes choppy or distorted. What can I do to improve my Zoom experience?

Use the best Internet connection you can.

In general:

  • Wired connections are better than wireless (WiFi or cellular) connections.
  • WiFi connections are better than cellular (3G/4G/LTE) connections.

Plan ahead for Zoom meetings, and as often as possible, join Zoom meetings from a location where you can use a fast, reliable, wired Internet connection.

Mute your microphone when you're not speaking.

When your microphone is on, Zoom will devote part of your Internet connection to an audio stream for you, even if you are not speaking. Mute your microphone when you do not need it, and you will allow Zoom use your Internet connection more effectively.

Stop your webcam video when you don't need it.

So long as doing so is okay with your instructor or moderator, start your video only when you need to show yourself on webcam, and stop your video when it isn't needed.

Disable HD webcam video.

Sending high definition (HD) webcam video requires more bandwidth than sending non-HD. Disabling HD video will free up more of your Internet connection for other parts of your Zoom meeting.
See: Disabling HD video in Zoom

Close other, unneeded applications on your computer.

Zoom meetings can demand significant memory and processing power from your computer. Closing other applications, ones you do not need during the session, will help Zoom run better.

Avoid other activities that will steal bandwidth.

Don't start other bandwidth-intensive activities just before, or during, a Zoom meeting. On your Zoom device—and as much as possible, on other computers and devices that share your Internet connection—avoid:

  • large downloads
  • large uploads
  • streaming video (e.g. Netflix, Hulu, YouTube)
  • cloud backups
  • cloud file synchronizations
  • other high-bandwidth activities

Communicate with the instructor or moderator of your Zoom meeting.

If the best Internet connection you have for Zoom is a slow one, such as a poor cellular data connection, let the person or people running your session know ahead of time.
