Sometimes, a firmware includes a bootloader update. If you skip major versions, you must update twice. Always read the "Release Notes" section immediately below the download link. If Ubiquiti writes "Intermediate firmware required," download that older version first.
Ubiquiti firmware can be downloaded directly from the official Ubiquiti Downloads page . Updates provide critical security patches, performance improvements, and compatibility for UniFi, airMAX, and EdgeMAX devices. 📥 Finding the Right File
