The configuration of a router is stored in profiles. Profiles can be downloaded to a computer and uploaded to the router to archive complete profiles aside of the router or transmit them to other routers.
Profiles can be downloaded from the router in two different formats:
Binary profile files are encrypted. This format is recommended to archive the profile or transmit it to another router, e.g. a backup device. Binary profiles cannot be tampered. Binary profiles can be uploaded quicker than ASCII configuration files.
ASCII configuration files are not encrypted and can be viewed and edited using a text editor. This format is recommended if the profiles must be adapted manually before uploading them to a router. Passwords will be removed from the ASCII configuration file due to reasons of security.
The configured profile of a router is to be downloaded to a computer and uploaded to the router again later.
It is prerequisite that you have access to the web interface of the router.
Downloading the profile to the computer
Uploading a (binary) profile to the router and activating it
Uploading an ASCII configuration file to the router and applying it
If the profile has been downloaded in ASCII format, the user passwords have been removed due to reasons of security.
These must be entered into the profile manually before uploading it to a router.
Otherwise, the router cannot be accessed any more after activating the profile.
To do this, the asterisks must be replaced by the password in the following line of the profile:
Open web interface of the router using a browser:
In the Administration → Profiles menu, select the configuration file in the Import profile or ASCII configuration file section and click on Import profile.
Apply the uploaded configuration (). 
Activate the uploaded profile () if desired.
