Wi-Fi networks prove indispensable for smartphones and tablets, allowing you to take advantage of connectivity anywhere in the house. Avoiding uncomfortable Ethernet cables is a blessing, but in some contexts Who tries to use your internet connection? without permission.
Actually, there’s no need to be too “paranoid”, because security systems are available and (using your modem router correctly) there should be no problems with access. However, to clear any “doubt”, you may be interested to know how to check the devices that are actually using your Internet connection right now.
In this case, what you might want to do is, modem router administration pageis usually “hidden” behind the address 192.168.0.1 or 192.168.1.1. It depends on the model you can use, but you should usually be able to find everything (including any passwords) on a label applied to the modem router itself, or at most in the user manual (alternatively, by doing a simple search on what’s on the Web). default passwords used by the reference brand can certainly help you if you really don’t remember anything).
After logging in, in any case a network overview. Again it all depends on the modem router model at your disposal, but it’s usually not hard to find “Wi-Fi”, “Connected devices” or similar sections where you can see what’s connected to the network (usually complete some models like Apple models have a trivial “–” or similar Even if it appears under the symbol, a simple verification of the local IP address or MAC address can help clear all your doubts.
For the rest, it is usually possible from the page that shows the devices, with the exception of differences with individual models of modem routers. Use the “Block” button (or similar) to prevent any “suspicious” device from accessing the Wi-Fi network. Of course, you’ll quickly know if you’ve blocked something that really belongs to you, because that device won’t connect to the network (later, if you’re wrong, you can obviously “unblock” it from the blacklist, but it’s worth checking before you block a device).
Alternatively, as noted by SlashGear, making a password change or using the latest security standard (like WPA3, if applicable) can help. Make your Wi-Fi network more secure. There is probably also a more “strict” approach, i.e. that depends on the MAC Filter functionality (which allows you to block specific MAC addresses). In short, there are several possibilities to check your Wi-Fi network and make sure everything is “in place”.
