Close any unnecessary programs and apps on your computer during the call

You and your guests should use a desktop computer or laptop for the best experience

If possible, the host and guest(s) should hardwire into their router to ensure the best possible internet connection

If possible, schedule your call when there won't be other demands on your internet connection, like someone playing on a game console or streaming television.

Ask your guests to run an internet speed test, https://www.speedtest.net/. We recommend you to have at least 5 Mbps upload and download speeds.
