FRITZ!Box 3490 Service - Knowledge Base
Certain settings are missing from the FRITZ!Box user interface
You would like to use or configure a specific function, such as DynDNS, in the user interface. However, the corresponding settings (such as menu items, buttons) are not displayed although these settings are present in the user interface of a different FRITZ!Box of the same type.
Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.
Simply proceed as described below. After each measure, check whether the issue persists.
1 Enabling the advanced view
- Enable the advanced view in the FRITZ!Box user interface.
2 Enabling the telephony function
The telephony function is hidden in the user interface in the factory settings. If you would like to use the FRITZ!Box's telephony function, you must therefore first enable the following setting:
- Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
- Click "Radio Network" in the "Wireless" ("WLAN") menu.
- Enable the option "Enable support for FRITZ!App Fon in the FRITZ!Box".
- Click "Apply" to save the settings.
3 The function cannot be used in the current operating mode
If certain settings (for example "online meter", "port sharing", "dynamic DNS", "IP settings" and "DSL information") are still missing, then this is due to the FRITZ!Box's operating mode (IP client mode or wireless repeater). When the FRITZ!Box is used as an IP client or a wireless repeater, some of its settings are grayed out because they cannot be used or do not make sense in that particular operating mode.
Note:If you would like to use the functions that are not available, you can configure them in the FRITZ!Box or router it is behind.
4 Function cannot be used with certain editions of FRITZ!Box
Various editions of the FRITZ!Box are available. Some are available in specific countries (for example special editions for Germany, Switzerland, Austria or international editions), and some editions are for a specific Internet service provider. The functions offered by these different editions can differ. As a result, the corresponding settings (such as menu items, buttons) are not available, although they are offered by a different FRITZ!Box of the same type.
