How to Set Up MAC Address Filtering

MAC address filtering lets you create a whitelist (allow only specific devices) or blacklist (block specific devices) on your router. Each network device has a unique MAC address that the router can use to control access.

Step-by-Step Guide

1. Login to your router — access the admin panel.
2. Find MAC filtering — look under "Wireless", "Security", or "Access Control".
3. Enable filtering — choose "Allow" (whitelist) or "Deny" (blacklist) mode.
4. Add MAC addresses — enter the MAC addresses of devices to allow or block.
5. Save settings — only listed devices will be allowed (or blocked).

Tips & Best Practices

• MAC filtering is not strong security — MAC addresses can be spoofed
• Always use it alongside WPA3 encryption
• Find device MAC addresses in your router's "Connected Devices" list
