How can I find out who uses my wifi?

The digital age has certainly made life easier for us, but the other side to the coin is that we are vulnerable to threats. Hence, it pays to be a little savvy when it comes to finding out who is hooking to your internet system. Fortunately, there are things you can do to make sure only authorised users can use your wifi. If you are asking yourself, who uses my wifi, take a look what you can do to protect yourself.


No doubt, it is not easy to detect if someone is using your connection because you cannot see it. You might feel that your upload or download time is rather slow more than usual, but you cannot be sure who is on your network. When this happens, you wonder to yourself, 'who uses my wifi?', then consider alternatives below.

  • Download a security software

There are programmes which can detect piggybackers on your network. One free software that works on Windows 2000, XP and Vista is 'Who is on my wifi'(whoisonmywifi.com). Once you download the software, it will show you the network and identify every device and computer on it. It will notify you if there is an unknown or unrecognised device. There is an ‘Online Service’ that will enable you to block access to the network. Anti-virus security systems (e.g., McAfee) have a function as well which inform you if an untrusted device is connected to your system.

  • Use administrator privileges

It is also possible to detect an intruder without downloading a software to your computer. You can do this by opening your web browser and typing in your IP address. Type in the username and password and then login. If this is your first time to login, then the username name is admin and the password is blank. Change the password immediately to protect your personal or home network. You can then kick off unwanted intruders.

Other methods

Another way to find out if you're asking yourself 'who uses my wifi' is to enable MAC filtering. Keep a white list of MAC addresses that you allow to hook on to your network. In addition, you can also enable encryption which will prevent intruders from hacking your system. WEP and WPA2 are the two types of encryption you can use on your routers. WPA2 is the most secure method.
