inSSIDer is a Wi-Fi scanning tool that helps users identify all nearby Wi-Fi signals. But there are free alternatives available.
For those who are not fond of the $19.99 price tag, there are many free or mostly free alternatives available. Let’s check out a few of the alternatives:
1) Wifi Analyzer
Wifi Analyzer is a free app designed to help users choose the best channel for their wireless router.

Disadvantages: There is no iOS support for this app at this time, so it will not work on Apple devices. At the time of the writing, there is also a bug that prevents the program from updating, and the only solution is to reboot the device.
