So if you want to find dead spots, strong spots and so on, you only need to walk around with your laptop and look at the signal strength as you move. It also shows a moving graph of the strength of each network over time. One especially useful feature is the signal strength display for each network, which includes an RSSI ( Received Signal Strength Indicator). It locates every network within range of your laptop and displays a tremendous amount of information about each: the network name (SSID), MAC address, channel it uses, type of encryption, manufacturer, type of 802.11 (b, g and/or n), maximum router speed, manufacturer and more. 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.
