is rolling out a new tool to its wifi product that will let people gain more insight with respect to the performance of their home network. The Google Wifi Network Check function lets people measure how each individual device is performing on their wifi network. "Knowing wifi 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," explained Google. Google says most users of Google Wifi have an average of 18 devices connected. The new tool means people can explore how each is connecting to the network and then make adjustments to improve performance as needed. The new feature in Network Check will be available in the Google Wifi app in the next few weeks.
