Hello,
I am reporting a major inconsistency in the firmware versioning for TL-SG3428MP v5.0.
-
Currently, my switch is running v5.0.25 (Stable), released in February 2026.
-
Surprisingly, the "Beta" tab still shows an older version v5.0.24 from December 2025.
3. When I try to manually upload the new v5.0.26 (Build 20260304) found on the community forum, the Omada Controller blocks it with the error: "This model in the selected location already has a specified software version."
It seems the Controller's upgrade rules are misconfigured, treating v5.0.25 as the ultimate version and refusing to recognize v5.0.26 as a valid update.
