The majority of us Android users live (or try to) near a WiFi Network to avoid high data bills at the end of the month and to take advantage of the connection speed. On occasion, our network can get sluggish, and one of the possible reasons is because there is more than one device connected.
Could there be someone using my WiFi connection? That is a question that all WiFi users have asked themselves, and in this article you will discover a trick to find if someone else is connected to your WiFi signal and how to block them.
Discover If Someone Is Stealing Your WiFi Signal with This App
Fing is an app that will help you find any problems in your WiFi signal. To find unauthorized WiFi users, you only have to be connected to your WiFi signal and tap on Refresh in the app. Once that is done, you will be able to see all the devices that are connected to your WiFi signal.
The app will mostly show you the MAC addresses of these devices and on occasion their name (Android, iPhone). To access the device’s information, you just need to tap on that option, and you will see a list of the device’s characteristics and the things we can do with it.
How to Block the Unauthorized WiFi User
Once you have seen the list of the devices that are connected to your WiFi signal, you only need to look for the ones that you don’t recognize and save their MAC addresses. To easily block these unauthorized devices, you will only have to gain access through the computer that’s connected to the router and search for the option that will allow you to filter a particular MAC and save the changes.
With this there won’t be a device that will go unnoticed in your WiFI signal, but if you want to do this process from your smartphone, there is an app that can help. The app is called WiFiKill and works just like the previously mentioned app except that once the unauthorized device is identified, you can filter its MAC so it won’t be able to connect to your WiFi signal.
For this app to work, your device will need to be rooted, and the device we want to block can’t have its MAC hidden. If your device is not rooted, you may want to consider changing your WiFi password regularly to keep those invaders away from your signal.
Conclusion
There will always be someone trying to get into your WiFi signal, so it is up to you to do everything possible to keep them at bay, and these apps will help you do that. You could try changing your WiFi password once a month to make it even harder for someone to figure it out.
