Apps like Fing (iOS/Android) or Who’s On My Wi-Fi quickly scan your network.
Within seconds, they show all connected devices, helping you spot intruders.
These apps are user-friendly and don’t require technical knowledge.
Step 3: Monitor Wi-Fi Activity
Observe your internet speed: sudden slowdowns can indicate unauthorized use.
Some routers show real-time bandwidth usage per device.
Step 4: What to Do if You Find Intruders
1. Change Your Wi-Fi Password
Create a strong, unique password (use letters, numbers, and symbols).
Update all your devices with the new password.
2. Enable WPA3 or WPA2 Encryption
Check your router settings and ensure encryption is enabled to prevent unauthorized access.
3. Block Devices
Most routers allow you to block specific MAC addresses.
Add unknown devices to the block list to prevent them from reconnecting.
4. Consider a Guest Network
