Buffering in Google Meet means your connection can't keep up with real-time video. Check your network speed — Meet needs at least 3.2 Mbps up/down for HD group calls. Close other browser tabs (Meet runs in the browser and competes with other tabs for resources). Switch to Ethernet if on Wi-Fi. In Meet, reduce video quality: click the three dots > Settings > Video > set Send resolution to Standard (360p) and Receive resolution to Standard. Turn off your camera when not speaking. Ask other participants to reduce their video quality too. Disable Chrome extensions that might interfere. If buffering only happens at certain times, your network may be congested — test your speed at the same time of day the meeting occurs. Google Meet doesn't have as many tuning options as Zoom, so network quality is even more important.
