On April 8, 2024, a 3rd party security researcher at Consumer Reports informed D-Link Corporation, of the D-Link Router Eagle Pro AI M18 AX1800 Smart Mesh Router included legacy cipther protocols, during negotiated communicaiton, that are considered unsecure as of this date.


As soon as D-Link was made aware of the reported security issues, we had promptly started our investigation. After an investigation across the family series we confirmed the report, and began patching.  The extended development time is due to time invested in to retesting performance and applying optimizations to use the acepted safe cipher suite in it's protected communication.


 D-Link takes the issues of network security and user privacy very seriously. We have a dedicated task force and product management team on call to address evolving security issues and implement appropriate security measures.
