Setting up the 1&1 DSL-Router with the 1&1 Start-Code

You can use the 1&1 Start-Code to automatically set up your 1&1 DSL-Router. Any telephone numbers that you have already registered with us will be automatically set up.


Important: If you change your internet password in the 1&1 Control-Center, your Start-Code also changes. This is not sent by letter, but can be found in your 1&1 Control-Center.

Enter your 1&1 Start-Code
Please note:
The appearance and menus may differ slightly depending on the firmware version of the DSL router.
Schritt 1
Open the user interface of your 1&1 DSL-Router. Enter http://fritz.box into the address line of your browser (Mozilla Firefox, Microsoft Internet Explorer or similar).
Alternatively, you can enter the IP address or the IP address you have set. If you have protected the user interface with a password, enter it now.

Check out the article entitled Cannot open the user interface for the 1&1 DSL-Router if you have any issues.
