Wifi networks are not foolproof and problems can arise at any time. If the connections do not work and if you are unable to connect, you need to scan the wifi networks around with an Android smartphone using some applications that work as tools by network administrators.
In this article we therefore see 5 wifi network scanner applications for Android that make us see, of a visible network, which router generates it and which devices are connected.
These are applications necessary to work as professional network administrators, which can also be useful for amateur / geek use for enthusiasts.

1) Fing is the name of one of the most popular programs for scanning a network which also exists as an application for Android smartphones and which offers one of the fastest ways to find out which devices are connected to the wireless network.
There are no limitations and you can easily find the IP address, name and MAC address of each connected device.
On these it is also possible to run direct tools such as Ping, traceroute, DNS searches and even use Wake on LAN.
2) Net Scan is another network mapping and port scanning tool capable of finding out the IP address, MAC address and device manufacturer (if available).
Once a network is discovered, it is also possible to check, on the various devices, which ports are open for remote operations and connectivity tests.
Net Scan does not include other integrated tools, but it is free, ad-free and very fast.
3) Network Scanner has a somewhat poor interface, but it is easy to use to scan connected devices in a wifi network, in a range of IP addresses.
Also with this app you will be able to see IP address, host name, brand, MAC address and control of open ports.
4) IP Tools is a toolkit to view detailed information on the network and connected devices, including the discovery of IP addresses and ports, tools such as ping, traceroute, Whois, Wake on LAN and DNS lookup.
You can also quickly access the web pages of devices (such as those of routers and servers) with a touch of the menu button.
5) ezNetScan offers a fantastic set of tools with an almost perfect interface to ping and traceroute, scan active services on devices, Wake on LAN, DNS search, NetBIOS name, TCP scan and search for installed software.
Once the scan is complete, ezNetScan allows you to send the results of all commands executed via e-mail.
And if the free version is not enough, you can buy the premium version with additional parameters.
To these tools I would also like to add zANTI, of which I have already spoken in the guide on LAN / Wifi network security verification simulating hacker attacks
