Home Wi-Fi inspection is available as part of Connectivity Labs.
Home Wi-Fi inspection, as the name suggests, will inspect your Wi-Fi signal at different places in your house/apartment. You can then either change the location of the router/modem or add extenders to increase signal strength at places where the signal is weak.
Seems is a nifty feature. No need to rely on 3rd party apps to measure Wi-Fi signal strength.
To enable Connectivity Labs, go to Settings > Connections > Wi-Fi > click on the 3 dots in top right corner > Intelligent Wi-Fi > click on Intelligent Wi-Fi 6 times.
