Connection via Microsoft WLAN Service Fails with WPA2
This non-secured condition should be used only for
testing, to find out whether a WLAN connection is pos-
sible at all.
3.
Remove the network cable and try again to establish a
connection.
If the attempt to connect to the WLAN using the non-en-
crypted connection is not successful either, check the in-
stallation of the WLAN adapter and contact the manufactur-
er of the WLAN adapter if necessary.

Connection via Microsoft WLAN Service Fails with WPA2
The WLAN connection to FRITZ!Box cannot be established
using the Microsoft WLAN Service (WZC) in Windows XP Ser-
vice Pack 2.
The required Microsoft patch for WPA2 (IEEE 802.11i) may
not be not installed.
Support for WPA2 in Microsoft WLAN service was not avail-
able until the current patch for Microsoft Windows XP Ser-
vice Pack 2.
Install the current patch from Microsoft:

IP Settings
The FRITZ!Box is equipped with its own DHCP server. This
means that FRITZ!Box assigns the connected computers
their IP addresses. The connected computers must be con-
figured such that they can receive their IP addresses auto-
matically. The steps for checking and adjusting this option
differ among the operating systems. See the relevant sec-
tion for your operating system.
If FRITZ!Box is operated in a network, no other DHCP server
may be activated in this network. If you need to operate a
DHCP server, please disable the DHCP feature in the “Ad-
vanced System Settings”.
