Introduction
Slow internet speed, sudden data usage spikes, and unknown devices connected to your network are common problems many WiFi users face today. If your internet feels slower than usual or your router shows unusual activity, someone may be using your WiFi without permission.
The good news is that you do not need any third-party app to check who is connected to your WiFi network. Your router already provides built-in tools that allow you to monitor and control connected devices easily.
In this complete 2026 guide, you will learn how to check connected devices, identify unknown users, block unwanted devices, and secure your WiFi network — all without installing any app.
Why You Should Check Who Is Using Your WiFi
Many people ignore checking their WiFi network, but it can create serious problems.
1. Slow Internet Speed
When multiple unknown devices use your internet, your bandwidth gets divided. This causes buffering, slow downloads, and poor video streaming.
2. Security Risk
Unauthorized users may access your personal data or monitor your online activity.
3. Data Usage Problems
If you use limited internet packages, unknown users can consume your monthly data quickly.
4. Network Stability Issues
Too many connected devices reduce router performance and increase connection drops.
Regularly checking your WiFi keeps your network secure and fast.
Signs Someone Is Using Your WiFi Without Permission
Before checking your router, look for these warning signs:
- Internet suddenly becomes very slow
- Router lights blink even when no one is using internet
- Unknown devices appear in network list
- Data usage increases unexpectedly
- Frequent connection drops
- Online accounts showing unusual activity
If you notice these signs, it is time to check connected devices.
Method 1: Check Connected Devices Using Router Admin Panel (Best Method)
This is the most accurate and recommended method.
Step 1: Find Your Router IP Address
Most routers use one of these IP addresses:
- 192.168.1.1
- 192.168.0.1
- 192.168.31.1
- 192.168.100.1
You can also check your router’s IP on the back of the router.
Step 2: Login to Router Settings
- Open your browser (Chrome, Edge, Safari).
- Type your router IP address in address bar.
- Enter router username and password.
Default login details are usually:
- Username: admin
- Password: admin or password
(You can find this on router label.)
Step 3: Find Connected Devices Section
After login, look for:
- Connected Devices
- Device List
- DHCP Clients List
- Attached Devices
- Wireless Clients
Every router has a slightly different interface.
Step 4: Identify Unknown Devices
You will see:
- Device name
- IP address
- MAC address
- Connection time
If you see devices you do not recognize, someone may be using your WiFi.
Method 2: Check Connected Devices Using Command Prompt (Windows Only)
This method works without router login but shows limited information.
Steps:
- Press Windows + R
- Type cmd and press Enter
- Type:
arp -a
- Press Enter
You will see a list of connected IP addresses. Compare them with your own devices.
This method helps identify unknown connections but cannot block users.
Method 3: Check Connected Devices Using Router Mobile Browser
If you cannot access a computer, you can use your phone browser.
Steps:
- Connect your phone to WiFi
- Open Chrome browser
- Enter router IP address
- Login to router dashboard
- Check device list
No app required.
How to Identify Unknown Devices on Your Network
Sometimes device names are confusing. Here is how to identify them.
Check Device Name
Look for names like:
- Android device
- iPhone
- Smart TV
- Laptop brand
- Unknown device
Check MAC Address
Every device has unique MAC address. Match with your own devices.
Disconnect Devices One by One
Turn off your devices and see which one disappears from list.
This helps identify unknown connections easily.
How to Block Someone From Using Your WiFi
If you find unauthorized devices, remove them immediately.
Method 1: Block Using MAC Address
- Login to router
- Go to Access Control or MAC Filtering
- Add unknown device MAC address
- Block the device
The device will never reconnect.
Method 2: Change WiFi Password (Recommended)
- Login to router
- Go to Wireless Settings
- Change WiFi password
- Reconnect your devices only
This is the fastest solution.
How to Secure Your WiFi Network (Important)
Checking devices is not enough. You must secure your network.

Prevents random users from finding your network.
Disable WPS Feature
WPS can allow easy unauthorized access.
Update Router Firmware
Updates fix security vulnerabilities.
Common Mistakes People Make
