Firmware Upgrade Instructions:

To update your product’s firmware, follow the instructions in your product’s user manual. To find your user manual, visit https://www.netgear.com/support/, enter your model number in the search box, and click the Documentation button on the product page.

Before updating the firmware on your wireless controller please read these release notes carefully. The update path to the latest firmware is dependent on the firmware currently running on your wireless controller, and the access point models manages.

NOTE:

CUSTOMERS UPDATING THE CONTROLLER FROM 5.5.1.X FIRMWARE MUST FIRST UPDATE TO THE MIGRATION FIRMWARE (5.5.1R.1) BEFORE UPDATING TO 6.5.5.24 RELEASE

If you have the WAC720 or WAC730 in your Controller network:

  1. Update the controller to 5.5.1R.1 firmware, which is bundled together with the 6.5.5.24 release zip file.
  2. Once the update is complete, login to the controller, and make sure that all the APs are in the connected state.
  3. You MUST wait for at least 15 minutes after all APs have reached the connected state before proceeding.
  4. After waiting for 15 minutes, update the controller to 6.5.5.24 firmware.
  5. Once the update is complete, log in to the controller and make sure all the APs have come to the connected state, so that clients are able to connect to the network, and the controller network is up and running.
Current Firmware Version Upgrade Steps
WC9500-5.5.1.X 5.5.1. X  ->  5.5.1R.1 -> 6.5.5.24

If you do NOT have the WAC720 or WAC730 in your controller network:

  • Upgrade the redundant controller first if available. Wait for the redundant controller to upgrade successfully and come back active.
  • Then upgrade in the order Slave 2, Slave 1 and Master controller.

Caveats:
When the update is from 4.x.x.x to 5.x.x.x and the Admin password has any special characters (example: "MyPassword!@#$%^"), change the password to alphanumeric only before updating (example: "Password"). Make a configuration backup, and update. After the update you can reset to your old password in 5.x.x.x.
