Mac Address Filter On Tplink Deco M4 __link__ Jun 2026

However, it is crucial to understand what MAC address filtering on the Deco M4 is not : it is not a robust security solution. The fatal flaw lies in the nature of MAC addresses themselves. Despite being "hard-coded," they are transmitted in plain text over the air during the connection handshake. Using easily available tools, a moderately skilled attacker can "spoof" or clone a permitted MAC address onto their own device, bypassing the filter entirely. Furthermore, the Deco M4’s interface does not alert the user to such spoofing attempts. Consequently, relying solely on MAC filtering is akin to using a flimsy padlock on a fence—it stops the honest opportunist but not a determined intruder. Encryption (WPA2/WPA3) remains the true gatekeeper.
