Wi-Fi network scanner - inSSIDer

The free inSSIDer software utility for Windows, iOS, and Android is one of the most useful and easy-to-interpret wireless networking tools I’ve encountered. InSSIDer displays information about the wireless networks in proximity to you, including an access point’s MAC address, encryption type, signal strength, and channel. InSSIDer is a great tool for wireless networking novices, because it has an easy-to-understand interface and includes an abundance of help and tutorials. Experienced Wi-Fi professionals may find the software a bit too light and might be more interested in a more robust program such as WiFiBuilder or Wireshark. But home power users looking to tweak their networks and those managing smaller business Wi-Fi networks would benefit by getting acquainted with inSSIDer.

What’s great about inSSIDer is that you can use it for several real-world purposes for your wireless network. For instance, say you are trying to find the best location to place an access point or router. Position the device and then fire up inSSIDER to see what  signal strength the software reports. This is really useful if you are trying to setup a Wi-Fi network in a place with lots of thick walls, glass or mirrors or multiple levels.

You can also use inSSIDer to tweak your wireless channel. In the U.S, there are 11 wi-fi channels. The channels recommended to set access points on are 1, 6, and 11, because they don’t overlap. So if you see many wireless networks in your area using channel 11 for example, by using inSSIDer you can change your access point or router to operate on channel 6 to tweak performance.


Yes, it may be lightweight for those who deploy wireless networks professionally. But anyone managing a home or small business wireless network will certainly benefit from the information inSSIDer provides. It earns a 4.5 out of 5 star rating and is easily a PCMag Editors’ Choice for networking utilities.
