Encryption
The most important security setting is encryption.
FRITZ!Box supports the security mechanisms WEP (Wired
Equivalent Privacy), WPA (Wi-Fi Protected Access) and
WPA2 as follows:
•
As part of the WEP mechanism a static key is deter-
mined to serve for the encryption of the user data.
Enter the key in the WLAN Security settings of the
FRITZ!Box. All of the WLAN adapters in your wireless
network must also use this key.
•
The WPA and WPA2 mechanisms provide for authen-
tication while the connection is being established.
For this a WPA password must be defined.
When WPA is selected, the TKIP encryption method is
used to encrypt the user data. In WPA2 the AES-CCMP
encryption method is used.
The encryption method you configure here must also
be supported by your WLAN adapter.
The user data are encrypted using an automatically
generated key. This key is regenerated at regular in-
tervals.
The WPA password used may be 8 to 63 characters in
length. For increased security, however, the pass-
word should be at least 20 characters long. Use nu-
merals, letters and special characters and combine
capitals and lower-case letters.
In the FRITZ!Box a method combining WPA + WPA2 encryp-
tion with the TKIP/AES-CCMP encryption method is pre-
configured. This setting allows you to use WLAN adapters
that support WPA (TKIP) or WPA2 (AES-CCMP) or both
methods.
It is advisable to change the preconfigured WLAN key as
soon as possible. Changes to the settings can be config-
ured on the FRITZ!Box user interface.
