Mac Address Filter On Tplink Deco M4 【CONFIRMED】

| Issue | Solution | |-------|----------| | Can’t find Access Control | Ensure Deco app is updated and you are logged into a TP-Link cloud account (not just local admin). | | Devices still connect after whitelist | Make sure Access Control is and “Allow only” is selected. Reboot the Deco system. | | Blocked device shows as “Unknown” | Wait a few minutes; the app will refresh. Or block again by tapping the device name. |

: While useful for administration, MAC filtering can be bypassed by "MAC spoofing" and does not replace strong WPA2/WPA3 encryption. mac address filter on tplink deco m4
