Installing the Patch for WPA2 with Microsoft WLAN Service
FRITZ!Box Fon WLAN 7570 vDSL
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
Configuration) in Windows XP with Service Pack 2.
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 availa-
ble until the current patch for Microsoft Windows XP Ser-
vice Pack 2. Install the current patch from Microsoft:
support.microsoft.com/kb/917021
Alternatively, you can install Service Pack 3 instead.
Ruling Out Interference Caused by Other Wireless
Networks
If there are other devices in the immediate vicinity of your
FRITZ!Box that use the 2.4-GHz band, simultaneous use of
frequencies can result in mutual interference (for example,
fluctuations or interrupted connections). Disruptions can
also be caused by other WLAN access points, or by
Bluetooth devices, garage door openers or wireless AV
bridges. In this case, please test a different radio channel
for your FRITZ!Box.
1.
Connect the FRITZ!Box to a computer using a network
cable. Proceed as described in the section "Connect-
ing Computer(s) to the LAN Port" from page 18.
