Manually Upgrade the Firmware on an AP

For efficiency and to keep up with new releases, you'll typically use automatic upgrades. But when needed, you can upgrade the firmware manually.

You can select either a single AP or multiple APs for firmware upgrades.

Note:

With the manual upgrade process, you can upgrade or downgrade the firmware on your AP. With the automatic upgrade process, you can only upgrade the firmware; you cannot downgrade the firmware.

If your AP is part of a site that has auto updates enabled:

  • You can either upgrade or downgrade the firmware version manually irrespective of the version configured for auto upgrade.
  • If you manually upgrade the firmware to a version that is higher than the version configured for auto upgrade, then Mist will not run an auto update on the AP (as this would downgrade the firmware version on the AP).
  • If you manually upgrade or downgrade the firmware to a version that is lower than the version configured for auto upgrade, then Mist will run the auto update process and upgrade the firmware version on the AP.

To manually upgrade the AP firmware:

  1. From the left menu, select Access Points.
  2. Use the Filter box to narrow down the list to show only the APs that you want to upgrade.
    For example, filter by entering tags, version number, or any of the fields listed in the table.
  3. Select the APs that you want to update.
  4. Click the Upgrade APs button in the top-right corner of the Access Points page.
  5. The Upgrade APs Firmware window appears. Click Proceed.

    Upgrade APs Firmware dialog box with message about auto-upgrade schedule. Buttons: red Proceed and gray Cancel. Close button at top-right.

  6. Select the firmware version to upgrade to, then click Next.

  7. In the Upgrade Settings section of the window, you can choose Download now or Download later..
    1. If you select Download now, the Reboot schedule will be set to Reboot now, but you can optionally choose Reboot later.
    2. Choosing Download later prompts you to set a date and time for the firmware download to occur. This will automatically select the Reboot later option in the Reboot Settings section of the window. The Reboot Time is set to the same date and time you chose for the Download time.

    You will see a blue banner appear at the top of your screen stating that the firmware download has started.
Note:

If you try to manually upgrade a disconnected AP, the upgrade process starts only when the AP reconnects to the Juniper Mist cloud.
