Check out the helpful tips and hints on how to run a survey for the most precise results.
When you are all done with the mapping, you can click on any Access Point on the map to display the signal heat map for that Access Point. Red is the strongest signal, while blue is the weakest.
The panel on the left side will display all Access Points your laptop could detect. Even if there are APs from neighboring network, it is not a concern as you can switch them off whenever needed.
Before saving the WiFi heatmap, look at all available visualizations to analyze the parameters of your WiFi network. NetSpot Home offers three main visualizations and NetSpot PRO and Enterprise have 16 visualizations for users with profound knowledge of WiFi networking.
Implementing the WiFi Heatmap knowledge
Now that you have a WiFi heatmap of your home or office you can take every benefit out of it. Studying the heat map thoroughly helps you see the weaknesses of your WiFi coverage and gives an idea where to start to fix the issue. So what you can possibly do:
Move the Access Point: The first thing to try, and the easiest, is moving the access point around. For example, when the signal is weak off the particular side of the AP, examine the structure of the building in that direction. Is there a concrete wall or a large metal cabinet or a fridge that is blocking the signal from access point? Something like this can be fixed by simply moving the access point further along to the other corner. Also moving the AP up from the floor and positioning antennas vertically (in case of moveable antennas) can change the situation to the better.
Switch Channels: When according to the WiFi heatmap you are getting a decent coverage, but the transmission speed and the connectivity in general fail, let NetSpot check the statistics on your Access Point and the Access Points that are leaking into the measured space. If you discover that your AP uses channel 6 just like some other APs leaking into your space, try switching to a less crowded channel 12. More useful information on selecting a WiFi channel can be found here.
Add in Access Points: If your space is wired for Ethernet, you can always add another Access Point at any cable termination spot to strengthen the signal.
Add in a Repeater: Most of the time WiFi routers and APs can be set up as WiFi repeaters. Repeating a WiFi signal can efficiently boost the range of an existing wireless network.
