Wi-Fi is a necessity for tons of connected devices in our homes. And when it isn’t working the way you expect, it can be a bit of a black box to troubleshoot. Google Wifi’s Network Check technology has always let you measure the speed of your internet connection and the quality of the network connection between your Google Wifi access points (if you have more than one). But what about that new smart TV in the bedroom that’s constantly buffering? Or your outdoor security camera with a flaky connection?

Starting today, we’re rolling out a new feature to Google Wifi that lets you measure how each individual device is performing on your Wi-Fi network. Knowing Wi-Fi coverage is poor in an area of your home can help you pinpoint the exact bottleneck when you notice a connectivity slowdown. Then, you’ll know to move your Google Wifi point closer to that device or even move the device itself for a stronger connection.
