It is no longer just computers and smartphones that log into the WLAN network. With many devices you can quickly lose track of who is on the go in your own network.
In the best case scenario, unauthorized access only slows down your Internet – but it would also be possible to read data sent over the network. Even if there is criminal activity on your network, there can be trouble TECHNOLOGY BUTTON has two simple ways you can keep an eye on who is on your network.
Monitor connection via router
Alternatively, you can look directly in the router’s user interface to see which devices are connected via WLAN. The disadvantage of this method, however, is that you do not receive a notification when a third-party device logs in.
With a Fritzbox you can find the connected devices under the item “Home network” and then “Home network overview”. In the “home network” you can also activate the “ Power Mode ” of your Fritzbox.
Monitor WLAN connections on the Telekom router
With Telekom routers, too, it is easy to find out who is in the network. To do this, simply open the router configuration and select the “Network” menu. In the “NAT & Port Rules” submenu there is a list with all the devices entered. Here you can switch off one device after the other in order to identify which device it is. Then name the devices accordingly. If an unknown device appears in the network, you can block the culprit immediately. You should also change your access data.

Scan also possible with the smartphone
The smartphone can also be used to quickly find out whether someone is in your own network. You can simply download a network scanner app for this. The most popular programs include Fing for Android and Apple , iNet – Network Scanner for Apple or Network Analyzer for Android or Apple . All three apps are free versions that can be expanded to pro versions with more functions. However, the free versions are definitely sufficient for a quick check.
Monitor WiFi network with PC software
This free Windows software scans the WiFi for all devices connected to it and presents them in a clear list. Here you can classify devices as “known” or “unknown” and name them individually so that you don’t lose track of things.
The software now automatically scans the WLAN at adjustable times and as soon as the program finds an unknown device, it sounds an alarm. So you always have an overview of what is going on in your home WLAN.
The disadvantage of “WhoFi”, however, is that you cannot act from within the program. If you have discovered a suspicious device, there is no way to exclude it from the network – you have to go through the router. In addition, “WhoFi” is completely in English and requires registration first.

What to do if unauthorized persons are actually in the WLAN?
If there are actually devices in the network that do not belong there, you should quickly change the WLAN password and log in again on your own devices. Also make sure that you are using the latest WiFi encryption method.
