How do I back up and restore the WRE2206 configuration?

To back up, go to Maintenance > Tools > Configuration and click Backup to save the current configuration file to your computer. To restore, browse to your saved configuration file in the same screen and click Upload. Do not turn off the WRE2206 while the configuration file upload is in progress, and after a successful restore, wait one minute before logging back in. (Page 49, 50)
