What kind of network connection should I use with Zoom video webconferencing?

It is best to use a broadband connection to participate in a Zoom meeting. In general, wired network connections do work better than wireless connections. Likewise, Wi-Fi is generally preferable to a cellular/data connection when using a mobile device. Given that video is exchanged, connection speeds have a direct impact on reception quality. For low bandwidth connections, try disabling video and join the meeting in VoIP (voice) mode only.
