2. After the AP goes online again, the AP upgrade still fails. Check the cause for the upgrade failure, which is displayed as Failure(The AP type is not matched).

3. Check whether the upgrade file name is correct.

   Use a text editor tool to open the upgrade file. The AP type displayed at the EFS tail in the upgrade file is not consistent with the upgrade file name.

4. After setting the AP type displayed at the EFS tail as the upgrade file name, the AP upgrade succeeds.

Procedure (CLI)

1. Check causes for the upgrade failure.

   Run the display ap update status ap-id ap-id command to check the causes for the upgrade failure.

   [AC6605-wlan-view] display ap update status ap-id 2
