Setting up FRITZ!Box for use with a 1&1 line

The FRITZ!Box is optimally prepared for use with 1&1 and gives you unlimited access to all features, including internet, telephony, and television (1&1 HD TV).

Simply connect the FRITZ!Box to the DSL line. The FRITZ!Box is then automatically configured by 1&1. You only have to enter your personal account information in the FRITZ!Box user interface if automatic configuration is not possible.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Having your account information ready

  1. Have your personal account information that you received from 1&1 ready.

    Note:You will find the account information in the security letter that 1&1 sent you before activating your connection. If you did not receive your account information, contact 1&1.

2 Connecting the FRITZ!Box with your DSL line

  1. Insert the DSL cable into the "DSL" socket on the FRITZ!Box and into the socket labeled "F" on the telephone jack.
