| How to Block Devices from Connecting to Your WiFi: |
Is your WiFi slower than usual? Do you suspect unauthorized users are connecting to your network? If so, blocking unwanted devices is the best way to secure your WiFi and ensure faster internet speeds for yourself.
This guide will show you different methods to block devices from accessing your WiFi network and protect your internet connection from intruders.
Why Should You Block Unwanted Devices?
Blocking unauthorized devices is crucial for several reasons:
✅ Boosts Internet Speed: Fewer devices mean faster internet. ✅ Enhances Security: Prevents hackers and data breaches. ✅ Stops Bandwidth Theft: Prevents freeloaders from using your WiFi. ✅ Reduces Data Usage: Helps you stay within your ISP’s data limits.
By blocking unauthorized devices, you can maintain a secure and efficient network.
1. Check Who Is Connected to Your WiFi
Before blocking devices, you need to identify which ones are connected to your network.
Methods to Check Connected Devices:
Via Router Settings:
Log in to your router using the IP address (
192.168.1.1or192.168.0.1).Go to the Attached Devices or DHCP Client List section.
Identify unknown devices.
Using WiFi Scanner Apps:
Download apps like Fing (iOS/Android) or Wireless Network Watcher (Windows).
Scan the network and view all connected devices.
✅ Pros: Helps you identify unauthorized users. ❌ Cons: Some devices might have generic names, making identification difficult.
2. Block Devices Using MAC Address Filtering
Every device has a unique MAC address (a hardware identifier). You can block a device using its MAC address.
How to Block Devices via MAC Filtering:
Log in to Your Router: Enter your router’s IP address in a browser and log in.
Find MAC Filtering Settings: Look for MAC Filtering or Wireless MAC Address Control.
Enable MAC Filtering: Turn on the feature and select Block Mode.
Add the MAC Address: Copy the MAC address of the device you want to block.
Save Settings and Restart Router.
✅ Pros: Blocks devices even if they have the correct WiFi password. ❌ Cons: Must manually add and update blocked devices.
3. Change Your WiFi Password
One of the easiest ways to remove unauthorized users is to change your WiFi password.
Steps to Change WiFi Password:
Log in to Router Settings: Enter your router’s IP address in a web browser.
Go to Wireless Settings: Find the WiFi Password or Security Settings section.
Set a New Password: Choose a strong password with a mix of letters, numbers, and symbols.
Save Changes and Reconnect Authorized Devices.
✅ Pros: Instantly disconnects all unauthorized users. ❌ Cons: You must reconnect all your trusted devices.
4. Use Your Router’s Device Block Feature
Many modern routers have a device block or access control feature.
How to Use Device Block:
Log in to Router Settings and go to Parental Controls or Access Control.
Select the Device to Block from the connected devices list.
Click on Block or Deny Access.
✅ Pros: Blocks unwanted devices with a single click. ❌ Cons: Some routers may not support this feature.
5. Hide Your WiFi Network (SSID Broadcasting)
Hiding your WiFi name prevents others from seeing your network and attempting to connect.
Steps to Hide SSID:
Log in to Your Router.
Go to Wireless Settings and find SSID Broadcast.
Disable SSID Broadcast and save changes.
✅ Pros: Prevents unknown users from discovering your WiFi. ❌ Cons: You need to manually enter the SSID when connecting new devices.
6. Enable WPA3 or WPA2 Security
Weak security settings (like WEP) make your WiFi vulnerable to hacking.
How to Upgrade WiFi Security:
Go to Router Settings.
Navigate to Wireless Security Settings.
Select WPA3 or WPA2-PSK Encryption.
Set a Strong WiFi Password.
✅ Pros: Stronger security prevents hacking. ❌ Cons: Older devices may not support WPA3.
7. Set Up a Guest WiFi Network
If you frequently have visitors, use a guest WiFi to keep your main network secure.
How to Create a Guest Network:
Log in to Router Settings.
Go to Guest Network Settings.
Enable Guest WiFi and set a separate password.
✅ Pros: Keeps your primary network private and secure. ❌ Cons: Still consumes bandwidth.
8. Disable WPS (WiFi Protected Setup)
WPS makes connecting easier but is also a security risk.
How to Disable WPS:
Log in to Your Router.
Find WPS Settings under Security or Advanced Settings.
Turn Off WPS.
✅ Pros: Prevents brute-force attacks. ❌ Cons: You must manually enter the WiFi password on new devices.
