What are the signs that someone is stealing my WiFi?
While there might be varied signs suggesting unauthorized use of your WiFi, common indicators include a noticeable slowdown in internet speed and unrecognized devices connected to your network. If you find that streaming videos or browsing the web has become sluggish when it previously was fast, it’s worth investigating further. Additionally, some routers allow you to see a list of connected devices, making it easier to identify any unfamiliar connections.
Another sign is when your monthly data usage exceeds your typical consumption. Many internet service providers (ISPs) provide usage statistics, so checking these can uncover abnormalities that suggest that someone else is utilizing your bandwidth. If you notice a significant uptick in usage without a reasonable explanation, it could be an indication of WiFi theft.
How can I see what devices are connected to my network?
To view connected devices, you can log into your router’s web interface, usually done by typing its IP address into a web browser. Frequently, this address can be found on the router itself or in the user manual. After entering your router’s IP address, you will be prompted to log in, requiring the router’s username and password. These credentials may also be located on the device or in the documentation that came with it.
Once logged in, navigate to the section of the interface that displays connected devices. This section may be labeled differently depending on the router model, such as “Device List,” “Connected Devices,” or “DHCP Client List.” Here, you will find a list of devices currently using your network, often with their names, MAC addresses, and sometimes their IP addresses. Reviewing this list can help you identify any unauthorized devices.
What should I do if I find an unknown device on my network?
If you discover an unknown device connected to your network, the first step is to remove it from access. Most routers provide an option to block or disconnect a device directly from the device list.
