If you don’t want to upgrade firmware by Local GUI, there is the other option to update firmware by FTP.

Step 1: Download the firmware to root C:\(do not change the file name) at your local PC.

Step 2: Open the Windows command prompt and type “ftp” (AP IP) to connect to the controller via FTP.

Step 3: Login as “admin” and password. 

Noted: The default password 1234 if you haven’t changed local device password.
