On this page, you have the option of using remote access to manually update the firmware on an access point managed by the WLC. For example, this can be useful for testing firmware on selected access points before using it productively. Select an access point based on its MAC address and select the appropriate firmware file. Next click on Start upload to load the firmware in the access point.
In order for the access point to use the loaded firmware, you must subsequently perform a restart. By enabling the setting Restart AP after updating the firmware you trigger an automatic restart as soon as the firmware upload is completed.
