I’ve been using this app a couple of years now. I installed it when I started working from home full time - before everyone in the neighborhood had wifi and range extenders. It’s been extremely useful in helping me both avoid and troubleshoot connectivity issues. Being able to determine at a glance whether it’s a signal issue/wifi issue or something else has saved me hours of pain.
