If you are concerned that someone might be stealing your Wi-Fi, there are a few tools at your disposal for finding out.
Note: Make sure to create a strong wifi password, and change it if you suspect that there is an unknown device that is connected to your wifi. If you are using your own modem you can use the admin tool by logging in or going to the manufacturer’s website of the modem it depends on what is the brand of your modem.
Check your Wi-Fi router's status lights
This is Applicable if you have devices that you just count in your hands, like cell phones, laptops, tablets, etc. either turn them off or set them to airplane mode. Then watch the status lights on your Wi-Fi router. With no devices using Wi-Fi, the lights should not be flickering or flashing. If they are, someone else is probably connecting to your network. If you have more just go to the next option.
Use a Wi-Fi detective app.
This will help you to monitor all of the devices that are connected to your network, it’s easy for you to identify each device if you will customize the name of the device. You can always do that using whatever application you want to use.
Fing is the #1 Network Scanner: discovers all the devices connected to your WiFi and identifies them, with our patented technology used also by router manufacturers and antivirus companies worldwide.
Use your router's app.
Most of the router has their own application when you bought them nowadays, it depends on what manufacturer/ Brands you have. If you are using your ISP equipment you may find it on their website, or you may call them for assistance. If you see an unauthorized client in your router's mobile app or admin control panel, select the entry for that device. You should see the option to block, ban, or eject the device.
If none of those other options are fruitful, your last (and often the most complicated) option is to log into your router's admin control panel in a web browser. To do this, you'll need to know:
Your admin username: By default, this is almost always "admin," though if you practiced good security hygiene, you changed it to something else when you first set up your router.
Your admin password: If you have an older router and you never changed the password, this might be hacker bait like "default" or "password." Hopefully, you've changed it.
Your IP address: Most of the time, your network's IP address is http://192.168.0.1/ — enter that address in a web browser and login if you are offered the opportunity. If that's not right, you need to find the IP address for your network: In the Start search box, type "ipconfig" and press Enter. Your IP address should be the "Default Gateway."
