Make Wi-Fi Troubleshooting a Breeze with NetSpot

The Signal-to-Noise Ratio (SNR) heatmap will show you where your signal strength is not strong enough to overcome the existing environmental noise from other electronic devices. Areas of yellow are of concern and red areas are critical. If your wireless network troubleshooting scan shows SNR issues, you will need to consider raising your signal strength or lowering the surrounding noise.

The Low Signal Level heatmap will show you where your signal strength is weak. Causes of weak signal strength include too much distance between the router and the device, or something physically blocking the signal between the router and device. If your WLAN troubleshooting scan shows areas of yellow and red signal levels, you may need to explore ways to boost your signal level.

The High Noise Level heatmap will show you where the levels of noise are high. Noise can be caused by electronic devices such as microwave ovens, cordless phones, Bluetooth devices, and wireless video cameras. If your wireless network troubleshooting scan shows areas of red and yellow, you may need to explore lowering the noise levels by identifying the interfering devices and removing or shielding them.

The Overlapping Channels heatmap shows your signal-to-interference ratio. This kind of interference is caused by other radio transmitters, such as your neighbor's wireless network. If your Wi-Fi troubleshooter scan shows red and yellow areas, you may need to change your network's WiFi channel to one with less interference.

If you do an active scan of your network, the Low Download Rate and Low Upload Rate heatmaps will show areas where your Internet connection speed is slow. If your troubleshooting scan shows red and yellow areas, you may need to consider boosting your signal strength or changing your hardware, protocols or bandwidth.
