Are you wondering why the slow home Wi-Fi network? After checking that all the router settings have been configured correctly and the ADSL line provider is not reporting any problems on the line, you will certainly be asked what the cause of the outage may be. Have you ever thought that someone could have managed to connect to your home network by saturating the bandwidth and slowing down the connection? This could be a problem to be seriously considered, even if the last thing we think about.

We do not believe or do not want to believe that some of our neighbors we may know well, can take advantage of our WiFi network to download movies or anything else, or use streaming services like Netflix or Prime video. Among the most plausible hypotheses you must also put the hypothesis of a neighbor who, not having an ADSL or Fiber line, can use yours. Although our neighbor does not have the network password, unfortunately there are several methods to crack one, so the only solution is to lock the device on a Wi-Fi network.

If this is the reality of the facts, luckily there is a solution that allows you to first check if someone is not connected to a device that you do not recognize connected to your home WiFi network. If so, find out how to lock device on Wi-Fi network and no longer make it connect to the internet using our network. If you need to know how to do it right away, all you have to do is continue reading this guide.

How to find out who is using your Wi-Fi network

The solution that I propose to you in this article can be useful again on other occasions. For example, when you have intruders at home, who know the data for accessing the Wi-Fi network, but because of an internet slowdown you would like them to disconnect. In order not to be rude and ask them to disconnect from home Wi-Fi, you can simply use the method I'm about to describe you. Or, if your child should be studying, he is in front of the computer playing online or surfing the internet with his mobile phone. In all these cases the contents of this guide may be useful to you. The only requirement before proceeding to block the device on the Wi-Fi network is to have an iOS device, Android or a computer at hand to detect the data needed to perform this procedure.

The first step is to find out who is using your internet network and if the connected devices are all of your knowledge or there are some intruders. To do this there are different methods using either a mobile device or a computer, downloading some functional applications for the purpose.

Analyze Wi-Fi network with smartphone or tablet

The most popular app is most used to perform a Wi-Fi network analysis for sure Fing, available for both iOS and Android. This app allows you to view not only all the devices connected to the WiFi network, but also to discover some useful data to uniquely identify the connected devices. The useful data you can view are the product name, the manufacturer's name, IP address, Mac address and others. This information will help you discover who the connected devices belong to, whether they are members of your family or find some device that you recognize as not belonging to your family.

A very useful data to be able to block abusive devicesMAC address which you will need to use later as you will see in the second part of the guide. Now let's see how to use Fing on your mobile devices. It should be noted that with the update of iOS 11, it is no longer possible to view the Mac address on the iPhone. The reason that Apple has blocked any app like Fing from accessing the MAC addresses in the ARP table of the iPhone operating system (iOS). Therefore, MAC addresses can no longer be acquired during a network scan performed on an iPhone. This app is equally useful on the iPhone, because it allows you to detect an intruder between connected devices. While, with an Android device you will be able to fully use all the functions, including the detection of the MAC address.

  • First of all make sure that your iOS or Android device is connected to the Wi-Fi network you want to keep under control.
  • Now download the free app Fing – Network Tools from Google Play Store or the free app Fing – Scanner of network fromApple's App Store.
  • When the installation is complete, start the app on the device.
  • A screen will appear with the name of your Wi-Fi network, followed by a list of connected devices, of which, by clicking on one of them, the IP address and the name of the device are shown. As you can see, the MAC address is dimmed on the iPhone. I also tried other similar apps like Net Analyzer but the result the same, the MAC was obscured by Apple.

While, as you can see from the image below, on the Android devices the MAC address is displayed by the Fing app itself.

Analyze Wi-Fi network with the computer

If you have an Apple Device or you don't have a smartphone and you want to analyze the Wi-Fi network, you can use an application to download to your computer. In my test I used, a free and very light software that you can download from this link. This application performs the same functions as the smartphone app, in practice it analyzes the WiFi network and extrapolates some data such as the device name, the manufacturer's name, the IP address and the MAC address.

Advanced IP Scanner a free, fast and reliable solution to analyze your WiFi network via your computer. Allows you to quickly and easily recover all the necessary information on the computers connected to the network by clicking Scan. It also has other interesting features like activating or shutting down a remote PC with a single click, or connecting via Radmin and performing many other operations on the remote computer.

Once you have identified a device that you do not recognize as belonging to your family, probably a stranger is using your WiFi network. Now it's time to lock device on Wi-Fi network by following these simple steps. Don't worry if you are not an IT expert, because if you follow the procedure described below, you will achieve the goal without any difficulty.

How to lock device on Wi-Fi network

If you realize that one of the devices connected to the network really shouldn't be, then keep reading the guide to be able to block and deny them access to your Wi-Fi network forever.

  • To block the unknown device connected to your Wi-Fi network, first locate the device that can be a computer, a smartphone or even a Smart TV. Score, taking over the first MAC Address with the methods explained above, the corresponding MAC number on a sheet of paper.

  • Now open the browser on your home PC connected to the WiFi network and connected to the router interface. If you don't know how to do it, you generally need to type in the address or in the address bar.
  • Login to log in to your router. Generally the username and password are set by default to admin or user, unless you changed them. If you don't remember the password, I suggest you read the router manual.

At this point you just have to find out how to block theaddress MAC of the unknown device via entering the router settings. This procedure can vary from router to router, but generally the steps to follow are these:

  • Enter the main page of the router. Be careful because in the Technicolor Smart modem router, the Mac address filter does not exist and you cannot filter individual devices.
  • Go to Settings/Advanced settings / WiFi.

  • Search for the item MAC Address Filter (Filter MAC) and add a device.
  • In the new page that will open, under the heading MAC Address (Mac Filter), enter the data of the device (MAC address) you added previously and then save the change made by clicking on apply (Apply).

This all. From now on, the unknown device will no longer be able to connect to your Wi-Fi network.

For added security, I also suggest you change the password of your router and enter a more complex one, so as to avoid other possible attacks on your home Wi-Fi network. I suggest you also read this guide to improve the protection of your WiFi network.
