Making sure that your Wi-Fi network is secure is essential to keep your data and yourself safe, so avoiding anyone else having access is crucial.
How to tell if someone is stealing your Wi-Fi
The easiest option is to check your Wi-Fi router‘s lights. Simply switch off all your devices, if possible, and then see if the status lights flash.
If they continue to do so, it means that someone is likely connecting to your network.
There are also apps which don’t require you to turn off all devices, like Wi-Fi Guard or even an official app for your router, which allow you to see which devices are connected to a router.
The most difficult option is to log in to your router’s admin control panel online, using your admin username and password alongside your IP address.
From there, you can access a network map, user log, or client list, which allows you to see devices which have connected.
How to stop someone stealing your Wi-Fi
If using a router’s official app, you can often see the option to block specific devices from connecting to the network.
This is also an option for some admin control panels for routers, but it is not always the case.
If neither of these are available options, then you should consider changing the password required to connect to your router.
To make a strong password, make sure that it is at least 12 characters long and features a variety of character types, such as lower case, upper case, numbers and punctuation.
Also avoid names or dates which could be easily guessed as these may even leave you open to being hacked again.
