If you don't want to go through the hassle of creating a heat map of your network, and would prefer something simpler and more straightforward to use, you should give Acrylic WiFi a try. (Note: While the product description page says it works only with Windows 7 and Windows 8, I've used it on several Windows 10 machines with no problem.) Pricing varies according to the size and complexity of your network.
HeatMapper lets you do surveys for only 15 minutes at a time Site Survey gives you unlimited time, along with additional features. HeatMapper is the free version of a more powerful Wi-Fi surveying tool called Ekahau Site Survey. Ekahau HeatMapper creates heat maps of Wi-Fi networks, showing areas of low and high coverage.
