Introduction
Is your internet slow even when no one else is using it? Chances are someone is secretly connected to your Wi-Fi. This guide shows you how to check who is using your Wi-Fi using free apps, router settings, and tools — no technical knowledge required!
Method 1: Using Your Router’s Admin Panel
This is the most accurate way to see who’s connected to your Wi-Fi network:
- Open your browser and type
192.168.0.1or192.168.1.1 - Login using your router’s username and password (usually on the back of the router)
- Go to Connected Devices or Device List
- Check each device name and MAC address
Tip: If you see any unknown device, change your Wi-Fi password immediately.
Method 2: Use a Free App to Detect Intruders
Several apps are available that scan your network and show all connected devices. Our top picks:
- Fing – Android & iOS (Free, user-friendly)
- Who’s on My Wi-Fi – Windows PC
- WiFiman – Android & iOS, from Ubiquiti
Method 3: Use Command Prompt (Windows)
For tech-savvy users:
- Open Command Prompt
- Type:
arp -a - This displays all devices connected to your network along with their IP and MAC addresses
How to Block Unauthorized Devices
- Change your Wi-Fi password from the router settings
- Enable MAC address filtering
- Turn off WPS and set encryption to WPA2 or WPA3
FAQ: Who Is Using Your Wi-Fi?
Q. Can I find out who is using my Wi-Fi with just a phone?
Yes, with apps like Fing or WiFiman, you can scan your network from your phone.
Q. What if I see devices I don’t recognize?
Change your Wi-Fi password and restart the router. This removes all devices until they reconnect with the new password.
