Pente's Chromebook has an issue of stalling during a Zoom meeting. Leo says that the Chromebook could be underpowered for video conferencing and as such, have problems keeping up. But it could also be an issue with the Chromebook's radio or network card. You get what you pay for and if the Chromebook is a budget model, it may not be able to handle the bandwidth. You can help by making sure there's no other tab or extension running.
A higher-priced Chromebook will have a faster processor, more memory, and better quality parts.
The chatroom recommends getting an external wifi dongle. It'll have a better antenna for reception.
