12.10 Mobile Network: Replacing Faulty DSL
Internet access over the mobile telephone network can be set
up so that the mobile telephone connection is established
automatically whenever the DSL connection fails. This guar-
antees Internet access even when the DSL connection is fails.
A USB modem for mobile Internet access (LTE/UMTS/HSPA)
and a SIM card from a mobile communications provider are
required for this.
Here is how to set up the mobile telephone connection as a
substitute upon DSL failure:
1. Insert the USB modem in the USB port on the FRITZ!Box.
2. Open the FRITZ!Box user interface; see page 28.
In the “Internet” menu, the sub-menu “Mobile Commu-
nications” is displayed.
3. Select the setting “Automatically enable the mobile con-
nection when the DSL connection is disrupted”.
4. Configure the settings for your Internet connection over
the mobile communications network. In the Help of the
FRITZ!Box user interface you can find detailed instruc-
tions.
Access to the Internet is now guaranteed, even when the DSL
connection fails.
As soon as the DSL connection is stable and available for at
least 30 minutes, the connection will be switched back to DSL.
The “Mobile Communications” menu is not available
until the UMTS/HSPA modem has been connected to the
USB port of the FRITZ!Box.
