Wi-Fi scanner apps for Android — one of the best categories of security tools available for Android to detect who is using our Wi-Fi without permission and also find out if there are any suspicious vulnerabilities or security issues within the network

While WiFi networks offer the benefit of the greater flexibility that is lacking in wired networks, they are more complicated to manage. Wi-Fi networks are not always well secured, and problems can arise at any time. So, using a Wi-Fi network work scanner is essential.

A Wi-Fi scanner is a tool that is designed to allow the user to identify nearby wireless networks and provide details of various network characteristics and statistics. They are one of the essential tools needed when planning, installing and maintaining a WiFi network.

If we suddenly lose the signal — which happens sometimes — of the wireless network and are unable to surf, we must start a scan of the Wi-Fi networks, using a Wi-Fi scanner app for Android and view all the connected devices, so as to check if there are some devices that we don’t know about.

In this article, we are listing some of the best Wi-Fi scanner apps for Android that provide information on the name of the network, which router generates it and which devices are connected. 

Some of these apps do allow checking the signal strength, but that’s not their main function. The main function is to scan the network to which we are already connected, thus showing useful information for a network administrator (for example, obtaining the IP address) or checking if there are any devices that are connected.
