In my case I came across names that I didn’t know what they were, like Hon Hai Precision (Foxconn, a huge electronics equipment manufacturer), or AzureWave Technology (wireless modules). They are companies that make network cards for a multitude of computers. But after logging in, I was able to know which of my devices they corresponded to.

AzureWave Technology: Google Chromecast
China Dragon Technology: TV Rivera
Murata Manufacturing Co. Ltd. : Samsung Galaxy S7 Edge

Touch on each of the computers that you do not know and write down its «MAC Address». It will serve you next to be able to block them.

Despite being logged in, you may come across devices under the name «Generic«. In that case, you can use this page to find out information about the seller.

We have done it exactly like that on a Huawei HG532S modem. We have found that, in this particular model, when the intruder tries to connect, he gets a “connection error”. That is, it cannot even hook into the network and there appears to be a problem with it.

More about the Fing Network Tools app

If you need to see more information about connected devices in the Fing app, just tap on them to see details. For example, the first time you were online, how long you have been online since, and the name of the network group, if you have one configured.

Additionally, Fing allows you to send a “Wake on LAN” packet from the Android device to any of the computers on the network. This is useful, for example, in case you want to turn on a PC from the Android device, as long as the PC is in sleep mode and has this function configured. It also allows you to ping a computer to see if there is correct connectivity with the mobile.

When a device has recently been disconnected from the network, Fing may also show it in the device list, but with an opaque color. If this device is selected, it will be possible to see in the information displayed that it is not active («down»). Active devices are displayed in bright color and indicate “up” in their detailed information.

If you handle the English language, you can enter the settings part where you will find several parameters related to all your Wi-Fi networks to which you have connected, TCP, Ping, «Traceroutes», DNS, Wake on LAN, TCP connection tester, etc.

Now that you know who is connected to your Wifi, you can check that the MACs of the listed computers correspond only to the computers in your home. If you find an intruder, the first thing you should do is change the Wi-Fi password and restart the modem or router.
