FRITZ!Box Fon WLAN – 7 Troubleshooting 61
WLAN Connection
You have established a WLAN connection to FRITZ!Box Fon
WLAN, but cannot open the user interface by entering
“fritz.box” or “192.168.178.1”.
Check IP Settings
A prerequisite for this check is that the IP settings in
FRITZ!Box Fon WLAN are the same as the factory settings ac-
tive upon delivery.
Make sure that the computer automatically obtains its IP ad-
dress from the DHCP server of FRITZ!Box Fon WLAN. For infor-
mation about how to check this settings and change it if
needed, see the section “IP Settings” from page 66.
Checking the WLAN Adapter Settings
Open the WLAN software you use to make settings for the
WLAN adapter and proceed as follows:
z Enter the key in hexadecimal format, not in ASCII format.
z Make sure that “Open” or “Open key” is set as the kind
of registration or authentication.
In the Windows XP WLAN software, this means you must
deactivate the “Network Authentication (integrated
mode)”. This setting is located on the “Association” set-
tings page in the “Wireless Network Properties” window.
z Check the key index. When operation is started for the
first time, the key index must be “1”.
If four fields are available for the key entry in your WLAN
software, “Key 1” through “Key 4”, then you must enter
the key in the field “Key 1”.
The Windows XP WLAN software has only one field for
the key entry, “Network key”. The key index must be set
in the field “Key index (advanced)”. This setting is locat-
ed on the “Assignment” settings page in the “Wireless
Network Properties” window.
