Saving Energy at the LAN Ports
For the individual LAN ports of your FRITZ!Box you can config-
ure various operation modes. The power consumption of
some modes is higher than others. Select the operation
mode that is best suited to your needs in order to minimize
the power consumption of the LAN ports.
The LAN ports can be configured in the FRITZ!Box user inter-
face. In the “System / Energy Monitor” menu, the following
operating modes are available on the “Settings” page:
Operating Mode
Functionality and Power Consumption

Help in Case of Errors
This chapter provides assistance if you are not able to open
the user interface of your FRITZ!Box or are having problems
with the DSL or WLAN connection.
For more comprehensive help, see the AVM knowledge data-
base in the Internet, which can be accessed at the following
address:

18.1
Cannot Establish a DSL Connection
The FRITZ!Box automatically establishes a connection to the
DSL network as soon as it is connected with the DSL line. If
the DSL connection is not established, check which kind (an-
nex) of DSL is set in your FRITZ!Box and attempt to resolve the
error.
Changing the Annex Setting of the FRITZ!Box
The FRITZ!Box cannot establish a connection to the DSL
network. This is signaled by the continued flashing of the
“Power / DSL” LED.
The kind of DSL (Annex A, B, J or M) set in the FRITZ!Box is not
the same as the annex used on your DSL line.
1.
Contact your Internet Service Provider to find out which
annex is used on your DSL line.
2.
Connect a computer with the FRITZ!Box either wirelessly
via WLAN or using a network cable.
3.
Open the FRITZ!Box user interface as described on
page 31
.
4.
Click the toolbar entry “Expert Mode” or in the “System /
Expert Mode”
menu to enable the expert settings of the
FRITZ!Box and confirm your setting by clicking “Apply”.

Click the “Internet / DSL Information” menu and select
the “Line Setting” tab. In the “Annex Settings” section,
make sure that the annex working on your DSL line is
set. Save your settings by clicking “Apply”.
After the annex setting has been changed, the FRITZ!Box re-
starts automatically. The connection to the DSL network has
been established as soon as the “Power / DSL” LED stops
flashing and remains lit up.

The User Interface Does Not Open
If an error message is returned when you open the FRITZ!Box
user interface, this can have various causes. Check the
causes listed below and attempt to resolve the error.
Restarting the FRITZ!Box
The user interface cannot be opened or does not react.
Inconsistencies within the FRITZ!Box.
1.
Restart the FRITZ!Box.
Remove the power cable from the outlet.
2.
Wait about five seconds before reconnecting to the pow-
er supply.
3.
To make sure that the FRITZ!Box has finished restarting,
wait until the “Power / DSL” LED lights up and stops
flashing and, if you have switched on WLAN, the “WLAN”
LED remains lit up as well. This ensures that the
FRITZ!Box restart has been completed.
4.
Try again to open the FRITZ!Box user interface by enter-
ing
fritz.box
in the address field.

The User Interface Does Not Open
If you still cannot open the user interface by entering
fritz.box
or by
192.168.178.1
, use the fixed IP address of the
FRITZ!Box as described on

.
Disabling Dial-up Connections
The user interface is not opened; a window for a dial-up
connection appears instead.
The browser must use the network connection between the
computer and FRITZ!Box when the user interface is opened.

connection must be disabled.
You can disable the automatic attempt to establish a Dial-up
Networking connection. The following example explains how
to check the settings of Internet Explorer 8:
1.
Select the “Connections” settings page under “Tools /
Internet Options”.
2.
In the “Dial-up and Virtual Private Network settings” sec-
tion, enable the option “Never dial a connection”.
3.
As a final step, click “OK”.
Disabling Online Operation
The user interface does not appear in the window of your web
browser.
The web browser is set for offline operation.
Configure the web browser for online operation. Using the ex-
ample of Internet Explorer 8:
1.
Open the “Tools” menu.
2.
If a checkmark is displayed in front of “Work Offline”,
click this line.
