What are the signs that someone is using my Wi-Fi without permission?
It can be challenging to detect unauthorized users on your Wi-Fi network, but there are several signs to look out for. One of the most common indicators is a sudden drop in internet speed. If your connection is slower than usual, it may be due to other devices siphoning bandwidth. Additionally, if you notice unfamiliar devices listed in your network settings, it’s a sign that someone may have accessed your Wi-Fi without your knowledge.
Another telltale sign is unusual activity on your network. If you’re seeing unexpected data usage in your monthly bill or activity logs, this might indicate that someone else is utilizing your network. Look for devices you don’t recognize, as well as any unexplained changes in your settings, such as altered passwords or new configurations.
How can I check who is connected to my Wi-Fi?
You can check who is connected to your Wi-Fi by accessing your router’s admin interface. To do this, you typically need to enter the router’s IP address into a web browser (common addresses include 192.168.0.1 or 192.168.1.1) and log in with your username and password. Once logged in, navigate to the section labeled something like “Connected Devices” or “Device List” to view the devices currently using your network.
Alternatively, there are third-party applications and software that can help you monitor connected devices.
