Cannot Establish a WLAN Connection
127
If the attempt to connect to the WLAN using the non-encrypt-
ed connection is not successful either, check the installation
of the WLAN device and contact the manufacturer of the
WLAN device if necessary.
Enable WLAN encryption again after completing the tests. Fol-
low the steps listed above and then enable the kind of en-
cryption that was previously configured.
Installing the Current Service Pack
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.
The required Microsoft patch for WPA2 (IEEE 802.11i) may not
be not installed.
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
established to the FRITZ!Box.
Ruling Out Interference Caused by Other Wireless
Networks
If there are other devices in the immediate vicinity of your
FRITZ!Box that use the same frequency band, simultaneous
use of frequencies can result in mutual interference (for ex-
ample, fluctuations or interrupted connections). Disruptions
can be caused by other WLAN base stations, but also by de-
vices like baby monitors, game consoles, garage door open-
ers, Bluetooth devices, or wireless AV bridges, which also use
the 2.4-GHz frequency band. In this case, please test a differ-
ent radio channel for your FRITZ!Box.
Alternatively, you can set the radio channel to “Autochannel”.
This enables the Autochannel function, so that the FRITZ!Box
searches for the best WLAN channel itself.
