Backup and Restore Configurations—Access point configurations can be saved as data files and later used to restore the access point configuration. This option lets you save access point settings in an external file or copy them from an external file to the access point. You can save an entire configuration for use as a backup to a single access point, or you can save a basic configuration, which can then be used in common by several access points in a network, providing an easy way to reconfigure all access points in a network.

You must have a TFTP server set up on which to store the backup files.

To back up a configuration — Type the IP address of the TFTP server and a name for the backup file in the spaces provided. Click Basic (to save a partial configuration) or Complete (to save an entire configuration) and click

Backup Configuration.

To restore a configuration — Type the IP address of the TFTP server and the name of the backup file in the spaces provided and click Restore Configuration. Restoring a configuration causes the access point to reset. If the file being restored was saved as a Basic configuration, only general configuration parameters such as SSID, country code, radio settings, security settings, RADIUS server settings, and management setup information are restored. Parameters that are unique to individual access points, such as device names, IP addresses, and administration passwords, are neither affected nor overwritten.

Before restoring a configuration you can view a description of the restoration point by clicking the Restore User Comment button. Comments made at the point the backup was created will appear in the “User Comments” field. This feature allows the user to select the correct restoration point.

To restore comments — Click the Restore Comments button to view comments saved on previous backups.

Factory Settings—Click Restore to load the factory default configuration and reboot the access point. All user-configured information is lost. You must reenter the default user name (admin) to regain management access to this device.

Reset Access Point—Click Reset to perform a hardware reset of the access point. Current configuration settings are not changed.
