These tools will help you monitor your network in real-time and provide additional confirmation of unauthorized access.
Check Your Router Settings
Beyond the device list, it’s worthwhile to regularly review your router settings. Make sure you are using a strong encryption method, preferably WPA3, and check the settings for guest networks, if applicable.
Steps to Secure Your Router Settings
- Navigate to the wireless settings section.
- Ensure your WiFi is using WPA3 or WPA2 encryption.
What to Do If You Discover Unauthorized Users
If you’ve confirmed that someone is stealing your WiFi, here are the essential steps you should take to protect your network.
1. Change Your WiFi Password
The easiest and most effective way to cut off unauthorized access is by changing your WiFi password. Ensure the new password is strong and includes a combination of letters, numbers, and symbols. A good example might be: X2f@9$e!Qu3.
2. Enable MAC Address Filtering
Every device has a unique MAC address. By configuring your router to only allow devices with specific MAC addresses to connect, you can prevent others from gaining access even if they have your password.
How to Enable MAC Address Filtering
- Log into your router’s admin panel.
- Look for the option labeled ‘MAC Filtering’ or ‘Access Control.’
- Add the MAC addresses of your authorized devices.
3. Set Up a Guest Network
If you frequently allow guests to use your WiFi, consider setting up a guest network with restricted access. This separate network will allow guests to access the internet without giving them access to your primary network and its connected devices.
4. Regularly Monitor Connected Devices
Routine checks on the devices connected to your WiFi can preemptively help you manage unauthorized access. By periodically reviewing this list, you can act faster if you notice a new, unfamiliar device.
Conclusion
In a world where we heavily rely on WiFi for our daily activities, ensuring its security is more important than ever. Through regular monitoring and implementing security best practices, you can dramatically decrease the likelihood of someone stealing your WiFi. Remember that a proactive approach not only boosts the performance of your network but also protects your personal and sensitive information.
