Enhancements
- Optimized the Internet page by moving Virtual WAN under Port Config and merging the separate Port Config and Load Balancing submit buttons into a single bottom action in Site > Network Config > Network Settings > Internet.
- Optimized Load Balancing logic to apply device-side settings when WAN Settings Overrides is disabled and added real-time port-status indicators under each WAN weight field to prevent user confusion in Site > Network Config > Network Settings > Internet > Load Balancing (requires gateway 6.2 firmware).
- Optimized Portal creation/editing with a rebuilt layout that groups settings more intuitively and exposes additional component-customization options in Network Config > Authentication > Portal.
- Optimized IP-input fields throughout the UI to accept a copied IP address pasted as a single string.
- Optimized Cloud Access with a redesigned connection flow that reduces cloud-request latency and improves overall user experience in Settings > Cloud Access.
- Optimized the DPI Rules Management page by replacing the single QoS toggle with a type selector that lets users choose between ACL and QoS rule types in Site > Network Config > Security > Application Control > Rules Management.
- Optimized controller security with built-in brute-force protection that locks login attempts after repeated password failures on "managed by other" devices in Controller (available now for AP & Gateway; Switch & OLT support planned for firmware 6.3).
- Optimized public OpenAPI documentation by completing deprecated-interface descriptions and correcting the categorization of site-template endpoints.
Bug Fixed
- Fixed bug where RADIUS Message-Authenticator was not forcibly validated, which could lead to RADIUS protocol security vulnerability (CVE-2024-3596), by adding support for enforcing Message-Authenticator verification when the “Require Message-Authenticator” option is enabled, in Site > Network Config > Profile > RADIUS Profile and Global/MSP > Settings > Server Settings > RADIUS Server.
- Fixed bug where RADIUS packets containing the Proxy-State attribute did not enforce Message-Authenticator validation, potentially exposing the system to RADIUS protocol security vulnerability (CVE-2024-3596), by adding support for limiting Proxy-State and enforcing Message-Authenticator verification when the “Limit Proxy-State” option is enabled, in Site > Network Config > Profile > RADIUS Profile and Global/MSP > Settings > Server Settings > RADIUS Server.
Notes
- Please note that Controllers on different platforms may vary in features, even if their first three digits of the version code are the same. For example, the Linux Controller currently supports Cluster Mode, but the Windows Controller doesn't support it yet.
- The Omada SDN Controller can only manage specific devices running the supported firmware. Please confirm that your device is compatible with the SDN Controller.
- Since version 5.14.32, the Omada Software Controller no longer supports upgrading from Controller v4.
- To strengthen overall security, we recommend upgrading all devices to the latest firmware.

Hello @GRL
I had a similar issue in the OC200 with an EAP653UR. Try to check it using the Chrome console.

My OC300 was upgraded successfully with the latest pre-release firmware. One minor issue that I have noticed is when the user clicks the Interference Detection button (under Network Tools, Interference Detection tab), the result usually does not appear even after refreshing the page with the icon in the upper right corner. This is especially true when there are no existing records. It is necessary to move off the page (by clicking another tab) and then return to the Interference Detection tab for the resulting record to be displayed. In doing a number of test scans, only once did a Scan Complete message appear. I believe this was also occurring with the previous firmware release.

@GRL I have the same issue, but only if I connect to the controller locally. When I use tp link cloud management, the issue is gone and the pics of EAP650 are as they should be.
