Using NetSpot for Easy Wi-Fi Detection

NetSpot is an easy-to-use wireless network detector app for Mac and Windows. It can help you to take a quick snapshot of the Wi-Fi networks around you. In addition, you can also use it to do a complete site survey of your entire wireless network area.

Wi-Fi detection is useful for many different situations, such as:

— When you're traveling and need to find an open network to connect to. Having a Wi-Fi detector loaded on your MacBook or laptop makes it easy.

— When you wish to test the limits of your Wi-Fi network's range, and determine just where your signal fades out.

— When you are having some weak signal issues and want to find out if other networks in the area are interfering with yours.

How to Use a Wireless Network Detector


Using NetSpot as a WLAN detector is easy. Simply install the NetSpot app and place your MacBook or laptop in the area you wish to survey. Once the program has loaded, click the switch in the upper-left corner of the screen to change it from "Survey" to "Discover." NetSpot will immediately detect all the networks in range and display them on screen. At a glance you will be able to see specific details about each wireless network detected in the area, including:

  • SSID – the name of the network
  • Channel – the channel the network is broadcasting on (1, 6, 11, etc.)
  • Band – the band the network is broadcasting on (2.4 GHz, 5 GHz, 20 MHz, 40 MHz)
  • Security Type – the kind of security the network has (WEP, WPA, WPA2, etc.)
  • Mode – which 802.11 protocol the network has (a/b/g/n/ac)
  • Level (SNR) – the network's Signal-to-Noise Ratio level
  • Signal level – how strong the network's signal is
  • Noise level – how much noise is interfering with the network

How To Use NetSpot for a Full WLAN Site Survey


If you wish to get a more complete picture of your wireless network, you can use NetSpot to do a complete site survey. This will allow you to perform WLAN detection at various points throughout your network area.

Complete WiFi Detection with NetSpot

If you have not used NetSpot before, read "How Do I Start My Survey?" before starting. Next, identify the area you wish to perform Wi-Fi detection on and upload a map of the area. You could also draw a map using NetSpot's map drawing tools. Then proceed with your survey, taking data measurements throughout the network area. Once you complete your survey, you will be able to view heatmap visualizations.

NetSpot's visualizations will allow you to see your signal strength, signal-to-noise ratio and signal-to-interference ratio coverage throughout the area you surveyed. There is also an AP Quantity visualization that will show you how many APs (access points or routers) are detected at every measurement point. NetSpot takes care of all of your wireless network detection needs.
