A coverage test will show you where AP signal strength is faltering. What you’ll need to do now is relocate APs, install additional hardware where required until you hit the sweet spot.

Unfortunately, WiFi is forever at the mercy of its environment. As your business grows, WiFi dependencies will change. There’ll be new departments created, rooms changed around, walls built, and Macs installed. All of these things, along with that new internet-enabled refrigerator and kettle, will affect wireless signal.
Therefore, it’s worth conducting a wireless site survey using NetSpot app at least twice a year, or when any obvious changes occur within your building. If nothing else, it will allow you to keep the peace. Afterall, good WiFi equals happy people!
