Obtaining an IP Address Automatically
Here is how to change the UPnP settings:
1. Open the FRITZ!Box user interface (see page 25).
2. Make sure that the expert mode is enabled in the “Sys-
tem / Expert Mode” menu.
3. Configure the UPnP settings in the “Home Network / Net-
work” menu on the “Programs” page.
11.2 Obtaining an IP Address Automatically
The FRITZ!Box has its own DHCP server, which assigns IP ad-
dresses to the connected computers. The connected comput-
ers must be configured such that they can receive their IP
addresses automatically. The steps for checking and adjust-
ing this option differ among the operating systems. See the
relevant section for your operating system.

tings” command.
4. Select the LAN connection between your computer and
the FRITZ!Box. Click the right mouse button and select
