An update to Google's Nest Wifi and Wifi routers will allow you to choose what traffic the devices will prioritize automatically. Using the Home app, you can select if it should prioritize activities like video conferencing or gaming. The feature arrives with the Q4 firmware update (v13099.118.19), and it requires version 2.31 of the Home app.
Heading into the Wi-Fi settings of the app, you should see the new Preferred activities option. The two choices are currently focused on the two activities mentioned above. For gaming, it will prioritize Stadia. While for video conferencing, it prioritizes apps like Google Meet and Zoom. It isn't clear if this network prioritization option only applies to the mentioned apps.
The update also adds some Wi-Fi events to the Home Feed, informing you if device connection issues are because of a wrong password or poor coverage. It can also let you know if there are mesh connection problems because of poor placement. You will also be notified of underperforming WAN ethernet links.
If you want to check if the update has made its way to you, head to the Google Wifi app under Settings > Network & general. There you can select the device you want to check.
