Installing the Patch for WPA2 with Microsoft WLAN Service
3. Click through “ WLAN / Security” in the menu and se-
lect “non-encrypted”. As a final step, click “Apply”.
4. 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
installation of the WLAN adapter and contact the manufac-
turer of the WLAN adapter if necessary.
Enable WLAN encryption again after completing the tests.
Follow the steps listed above and then enable the kind of
encryption that was previously configured.
Installing the Patch for WPA2 with Microsoft WLAN Service
The WLAN connection to FRITZ!Box cannot be established
using the Microsoft WLAN Service (WZC = Windows Zero
Configuraion) in Windows XP with Service 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 with
Service Pack 2. Install the current patch from Microsoft:
support.microsoft.com/kb/917021/EN-US/
Alternatively, you can install Service Pack 3 instead.
This non-secured condition should be used only for
testing, to find out whether a WLAN connection is
possible at all.
