To troubleshoot any issues with your WiFi start with performing a site survey in the NetSpot app. New to NetSpot? Not a problem! Just read "How Do I Start My Survey?" and follow the comprehensive guide. First of all identify the area you are troubleshooting. Then you can either upload a map to NetSpot or draw it from scratch.

Once you have a map, you can start taking data samples of your area. When done, you will be able to see the heatmap NetSpot built based upon the measurements you've taken.

Thanks to the Signal-to-Noise Ratio (SNR) heatmap you can easily see where the signal doesn't have enough strength to overcome the noise created by other electronic devices in the area. Yellow and red areas are those of concern, with red being critical and needing to be taken care of in the first place.

Refer to the Low Signal Level heatmap to see the areas of weak signal. Weak signal strength might be caused by a router being too far from a device or by an obstacle between router and device physically blocking the signal. If you see yellow and red areas on your heatmap, you might want to explore ways to strengthen the signal there.

You'll easily determine the areas with high noise levels thanks to the High Noise Level heatmap. Even such appliances as microwave ovens can cause noise and lower the strength of WiFi signal. If you see yellow and red areas on your heatmap — look for electronic devices that might be causing the issue and try moving them to another spot.

Use the Overlapping Channels heatmap to see the areas that have critical signal-to-interference ratio. The red and yellow areas will show you where the interference is the highest. Try changing your network's WiFi channel to eliminate the issue.

To see where your Internet connection speed is slow, perform an active scan of your network, and refer to the Low Download Rate and Low Upload Rate heatmaps. If you see red and yellow areas, you might need to change the protocols or bandwidth, or upgrade your hardware.
