How do you block someone from using your WiFi router?

Locking the Digital Door: How to Block Devices from Your WiFi

Sharing is caring, but not when it comes to your WiFi. Unwanted guests on your network can slow down speeds, eat up bandwidth, and even pose security risks. Luckily, reclaiming control is easier than you might think. Here’s how to block specific devices from accessing your WiFi using MAC address filtering.

What is a MAC address?

Think of a MAC (Media Access Control) address as a unique fingerprint for a device that connects to a network. Every phone, laptop, and tablet has one, and your router uses it to identify different devices.

Let’s Block Them Out!

1. Access Your Router’s Settings: This usually involves typing your router’s IP address (often found on the router itself or in its documentation) into a web browser. Common addresses include 192.168.1.1 or 192.168.0.1. You’ll be prompted for a username and password (again, check your documentation if you haven’t changed these).

2. Find MAC Address Filtering: The location varies between router brands and models, but common places to look include sections like “Wireless,” “Security,” “Access Control,” or “Advanced Settings.”

3. Enable MAC Filtering: Once you find the setting, turn it ON.

4. Choose “Deny” (Blacklist) or “Allow” (Whitelist):

   • Deny: This creates a blacklist. Add the MAC addresses of the devices you want to block.
   • Allow: This creates a whitelist. Only devices with listed MAC addresses will be allowed to connect. This option offers stronger security but requires more initial setup.

5. Add the MAC Address: You’ll need to find the MAC address of the device you want to block. This is usually found in the device’s WiFi settings.

6. Save Your Changes: Most importantly, don’t forget to save the changes you made in your router settings.

Important Notes:

• MAC addresses are alphanumeric: Double-check you’ve entered them correctly to avoid unintended blocks.
• Security isn’t foolproof: While effective, MAC filtering can be bypassed by tech-savvy individuals. Combining it with a strong password and other security measures offers the best protection.

By taking these steps, you can regain control of your WiFi network and ensure only authorized devices have access. Your internet speed (and peace of mind) will thank you!
