  • Firmware for the airMAX M devices and older Legacy (non-airMAX) devices are found under two separate menus on the download page.
NOTE: In the event your firmware update does not go through after multiple attempts, or if you cannot access the airOS Web UI, you can perform a TFTP firmware recovery by following the steps here.
