FRITZ!Box 3272 74
Mobile Network: Replace Faulty DSL
Setting Up IPv6 on the Computer
You can establish connections in the IPv6 range of the Inter-
net only if IPv6 is installed and enabled on the computers in
your home network.
• IPv6 is already installed and enabled in the Windows 7
and Windows Vista operating systems.
• IPv6 is not installed and enabled in standard
Windows XP. You must install and enable IPv6 in order to
use it. The IPv6 installation requires Service Pack 2 for
Windows XP.
• IPv6 has been available in the Mac OS X operating sys-
tems since Mac OS 10.
11.10 Mobile Network: Replace 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
missing. A USB modem for mobile Internet access (UMTS/HS-
PA) and a SIM card from a mobile communications provider
are required for this. The FRITZ!Box supports UMTS/HSPA mo-
dems from various manufacturers.
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 26).
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”.
The “Mobile Communications” menu is not available
until the UMTS/HSPA modem has been connected to the
USB port of the FRITZ!Box.
