Setting up the FRITZ!Box for use with a fiber optic connection from WEMAG

The FRITZ!Box is optimally prepared for use with WEMAG. Simply connect the FRITZ!Box to the fiber optic connection. The FRITZ!Box is then automatically configured by WEMAG. The complete FRITZ!Box range of functions for internet, telephony, and television (WEMAG TV) is then available to all of the devices in your home network without restriction.

If WEMAG did not provide you with the FRITZ!Box, contact WEMAG's customer service to have the FRITZ!Box configured automatically or have them send you information on how to manually configure the FRITZ!Box.
