Sometimes devices may have unfamiliar names or appear simply as “unknown.” Cross-reference these devices with what you actually own.
Finding the MAC Address
If you stumble upon a device you don’t recognize, take note of its MAC address. A MAC address is a unique identifier assigned to network interfaces for communications on the physical network segment. Here’s how you can find out the MAC addresses of your own devices:
- For Android: Settings > About Phone > Status > WiFi MAC address.
- For iOS: Settings > General > About > Wi-Fi Address.
- For Windows: Command Prompt > type “getmac” and hit Enter.
- For Mac: System Preferences > Network > Wi-Fi > Advanced > Wi-Fi Address.
By comparing the unknown MAC address with the MAC addresses of your own devices, you can determine whether the connected devices are yours or potential intruders.
Step 3: Changing Your WiFi Password
If you identify unauthorized devices that you cannot recognize, it’s crucial to take immediate action to secure your network. Changing your WiFi password is one of the most effective ways to kick out intruders.
How to Change Your WiFi Password
- Log into your router’s admin panel again.
- Locate the “Wireless” or “WiFi settings” section.

- Enter a strong, unique password that combines letters, numbers, and symbols.
- Save your changes and restart your router.
Remember: After changing your password, you will need to reconnect all your authorized devices using the new password.
Step 4: Implementing Additional Security Measures
In addition to changing your WiFi password, consider taking further steps to secure your network:
Enable WPA3 or WPA2 Encryption
Using a strong encryption method is critical. If your router supports it, enable WPA3 encryption for maximum security. If not, use WPA2, which is the next best option.
Disable WPS
WiFi Protected Setup is designed to make connecting devices easier but can also act as a vulnerability. Disabling this function will help secure your network.
Create a Guest Network
If you often have guests needing access to your WiFi, consider setting up a separate guest network. This will keep your main network secure while allowing guests to connect without exposing your devices.
