When your WiFi connection is inconsistent during a Zoom meeting, for example if you are traveling, consider joining the audio portion of the meeting via your phone. If you loose network connectivity on your laptop, you can stay connected to meeting audio from your phone. If you connect via your phone for the audio portion of the meeting, you should avoid connecting to the audio via the web interface, or you'll create an audio feedback loop. 

If you enter your participant ID as indicated in the below instructions, you will be disconnected from the phone audio if your laptop loses network connectivity. Instead, simply do not enter a participant ID. This way your video will not be tied to your audio connection.
