Encryption
The most important security setting is encryption. FRITZ!Box
Fon WLAN supports the security mechanisms WEP (Wired
Equivalent Privacy), WPA (Wi-Fi Protected Access) and WPA2
as follows:
z
As part of the WEP mechanism a static key is deter-
mined to serve for the encryption of the user data. The
key must also be entered in the WLAN settings of the
WLAN clients.
z
The WPA and WPA2 mechanisms provide for authentica-
tion while the connection is being established. For this
a WPA password must be defined.
Select an encryption method to be used to encrypt the
user data:
TKIP or AES, depending on which is supported by your
WLAN adapter.
The user data are encrypted using an automatically
generated key. This key is regenerated at regular inter-
vals.
The WPA password used may be 8 to 63 characters in
length. For increased security, however, the password
should be at least 20 characters long. Use numerals,
letters and special characters and combine capitals and
lower-case letters.
Encryption Configured in the Factory Settings
In the FRITZ!Box Fon WLAN a WPA encryption with the TKIP
encryption method is preconfigured.
It is advisable to change the preconfigured WLAN key as
soon as possible. Changes to the settings can be configured
on the FRITZ!Box Fon WLAN user interface.
Changing the Encryption Method: Recommendations
If your WLAN adapter supports an encryption method that is
more secure than the one preconfigured in your FRITZ!Box
Fon WLAN, you should select the more secure encryption
method in your FRITZ!Box Fon WLAN.
