FRITZ!Box 4020 Service

Certain settings are missing from the FRITZ!Box user interface

You want to use or configure a certain function in the FRITZ!Box user interface. However, the corresponding settings, for example menu items or buttons, are not displayed although these settings are present in the user interface of a different FRITZ!Box of the same type.

Simply proceed as described below. After each measure, check whether the problem persists.

1 Enabling the wireless network

Some wireless settings are only displayed if the wireless network is enabled:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the wireless network.
  4. Click "Apply" to save the settings.

2 Enabling the telephony function

The telephony function is hidden in the user interface in the factory settings. Therefore, enable the following setting if you want to use the FRITZ!Box's telephony function:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Enable support for FRITZ!App Fon in the FRITZ!Box".
  4. Click "Apply" to save the settings.

3 Answering machine was removed from FRITZ!OS 7

The answering machine had to be removed from FRITZ!OS 7 to make it possible for your FRITZ!Box model to support Mesh with FRITZ!. The answering machine can therefore no longer be configured. If you would rather use the answering machine instead of Mesh, you can install an older FRITZ!OS.

4 The provider updates FRITZ!OS

If you received your FRITZ!Box from your internet service provider, the provider hides the "Update" menu because the provider automatically installs the new FRITZ!OS. It is therefore not possible to install an update using the FRITZ!Box user interface. Refer to your provider for information on the new FRITZ!OS version and possible dates.

5 FRITZ!Box is configured as a Mesh Repeater / IP client

If the FRITZ!Box is configured as an "IP client" under "Internet > Account Information", all of the settings that cannot be used in this operating mode are hidden. This is the case with port sharing, dynamic DNS, IP settings, and the online meter. If the upstream router makes these functions available, you can configure them in the router.
