After the automatic upgrade function is configured, an AP checks whether its version is consistent with the AP software package version configured on the AC when going online. If they are inconsistent, the AP enters the automatic upgrade process. When configuring automatic upgrade, ensure that the AP software package name, FTP server address, user name, and password are correct, and that the AP software package is correctly uploaded to the AC or FTP/SFTP server.
If the automatic upgrade configuration is incorrect, the AP may fail to be upgraded automatically. In this case, the AP restarts to restore the configuration. If the configuration is still incorrect after the AP is restarted, the preceding process is repeated when the AP goes online. As a result, the AP restarts repeatedly when going online.
