Important: After installing this firmware, we strongly recommend performing a factory-default reset to activate every new security adjustment.

Security Enhancements

- HTTPS on 8443 – Management interface now served over TLS by default.
- UPnP Disabled – Universal Plug and Play starts in the off state for reduced surface exposure.
- AiCloud Authentication Hardening (CWE-287) – Added layered verification.
- Authentication Logic Refactor – Removed redundant code paths for a lean sign-in flow.
- Memory Safety Guard (CWE-476) – Introduced null-reference protections across critical services.
- Enhanced IPsec Parameter Validation – The existing input checks have been hardened.
- Data Exposure Mitigation (CWE-200) – Reinforced controls on sensitive pathways.
- Detailed Audit Trails – Expanded logging within the authentication module.

System Improvements
- Connection Stability – Core algorithms refined for steadier links.
- Scheduling Accuracy – Timed tasks execute reliably under PPPoE, PPTP and L2TP WAN modes.

Can the previously exported configuration file be used after the required router and node resets, even if it comes from a previous firmware version?
This because manually reconfiguring the entire system can be quite time consuming.

I'm selling my Asus!

I don't know what the folks at Asus are doing, but the Smart Connect feature is no longer available for the 5.1 and 5.2 GHz bands. You have to use a separate SSID's or a tri-band configuration with 2.4 GHz. I was generally happy with the XT9 combination, except for a few minor issues. It took me more than four hours and endless restarts to revert to the previous firmware version and solve the HTTPS certificate problem.

No more Asus!
