How to check who is stealing you WiFi

I am sure that when Anne Frank said “No-one has ever become poor by giving” she didn’t mean giving off free internet to others. Not only does it make us poor but a slow internet also makes us grumpy.

Did you anytime feel that your internet is getting slower by the day? Be it slow loading of the Web pages or the YouTube video takes infinite time to buffer? Well with the exponential increase in smart phones with WiFi connectivity, there is a high possibility that someone is stealing your internet.

This is how you can check the number of devices that are connected to your WiFi.

Login into your router settings and check the section that gives you the list of gadgets connected to your network. From the list of devices shown there, if you find any suspicious device, be sure that someone is eating away your bandwidth.

To log into your router setting open any browser (IE, Chrome, Safari etc) from any device which is already connected to your network and enter the following in the address bar : HTTP://

This would take you to your router login screen where it asks you to authenticate via credentials to access your router settings. Enter “admin” in both the username and password fields as these are the default credentials for most of the routers.

The password is different for different models and here are some of the password combinations you can try.

Username : admin OR Unknown OR None
Password : admin OR Unknown OR password OR blank (i.e. don’t enter anything)

After logging in, click on Stats or Wireless and there you would be finding the list and number of wireless connections to your network. If the number you recognize doesn’t add up to the number specified here, you can clearly assume that someone is stealing your internet.

Though there are ways to add the specific MAC ID to your filter list to stop the device from hereby connecting to your network, we suggest you to change your WiFi password as a better way to ward of all such freeloaders.

There are also other ways to check if anyone is using your network by the use of a number of 3rd party apps like Fing etc and the best way to teach them a lesson would be to get into their system using Kali & turn their files upside down (pun intended) xD

Well we hope this post will help you in identifying those bandwidth leeches and as a P.S we would say that always prevention is better than cure and hence have your WiFi password protected (at least 15 characters).
