To understand MAC address filtering, one must first understand the MAC (Media Access Control) address itself. This is a unique 12-character hexadecimal string hard-coded into every network interface card—be it a smartphone, laptop, or smart bulb. Think of it as a serial number or a fingerprint. When a device tries to connect to the Deco M4, the router checks this fingerprint. With MAC filtering enabled, the Deco M4 compiles two lists: an "Allow List" (whitelist) and a "Deny List" (blacklist). If the "Allow List" is active, only devices whose MAC addresses are explicitly entered can connect; all others are rejected. Conversely, the "Deny List" blocks specific troublemakers while allowing everyone else. Select "Block all new devices

Select "Block all new devices..." .

Now, tap "Manage Allow List" .

Tap the + icon to add devices. You can either select from devices currently online or manually enter a MAC address.

Add every single device that you own (phones, laptops, printer, smart speakers).

Think of it like a car’s VIN number. You can change the license plate (the IP address), but the VIN stays the same for life.

Allow List (Whitelist): Only devices on this list can connect. All others are blocked. Add Devices:

Go to the phone’s Wi-Fi settings for your Deco network and turn off "Private Wi-Fi Address." The phone will then use its real, permanent MAC.
Or, use the Deco’s device list to block each new random MAC as it appears (chasing MAC addresses is tedious).
