Service

using the Microsoft WLAN Service (WZC) in Windows XP
with Service Pack 2.

Errors During Data Exchange with Other Devices in the Network
Checking the WLAN Access Point
The FRITZ!WLAN USB Stick N and the WLAN access point
cannot exchange any data with each other.
Possible Cause
The required Microsoft patch for WPA2 (IEEE 802.11i)
may not be not installed.
Remedy
Support for WPA2 in Microsoft WLAN service was not
available until a patch for Windows XP with Service
Pack 2. Install the current patch from Microsoft:
http://support.microsoft.com/kb/917021
Alternatively, you can install Service Pack 3 instead.
Possible Cause
The WLAN access point is not connected correctly or not
switched on.
Remedy
Check whether the WLAN access point is connected cor-
rectly and make sure that the device and the WLAN func-
tion are switched on.
