If you cannot establish a non-encrypted WLAN connection,
make sure that the WLAN adapter in your computer is in-
stalled correctly. If the error cannot be remedied, contact the
manufacturer of the WLAN adapter.
Installing the Current Service Pack for Windows XP
The WLAN connection to the FRITZ!Box cannot be established
using the Microsoft WLAN Service (WZC: Windows Zero
Configuration) in Windows XP with Service Pack 2.
Cause
The required Microsoft patch for WPA2 (IEEE 802.11i) may not
be not installed.
Help
Install Service Pack 3 (SP3) for Windows XP, available as a
free download from Microsoft. Then Microsoft WLAN Service
will support WPA2, so that a WLAN connection can be estab-
lished to the FRITZ!Box.
FRITZ!Box 3370
Connect a computer to the FRITZ!Box with a network ca-
ble (see
page
17).
Open the FRITZ!Box user interface (see
Select "WLAN / Security".
Enable the "non-encrypted" option.
Click the "Apply" button.
Remove the network cable and try again to establish a
connection.
Disable WLAN encryption only for testing. Enable WLAN
encryption right away after completing the tests.
