Security
Encryption
The most important security setting is encryption. The
FRITZ!Box supports the security mechanisms WPA (Wi-Fi Pro-
tected Access) and WPA2.
WPA and WPA2 provide for authentication while the connec-
tion is being established. For this a WPA password must be
defined in your FRITZ!Box.
The WPA password must be between 8 and 63 characters. We
recommend a length of at least 20 characters. In addition to
numerals and letters the password should also include other
characters. Mix upper-case and lower-case letters.
WPA uses the TKIP encryption method to encrypt the user da-
ta. The security mechanism WPA2 uses the AES-CCMP encryp-
tion method.
The encryption method you configure in your FRITZ!Box must
also be supported by your WLAN device.
Default Setting of the FRITZ!Box
In the FRITZ!Box a method combining WPA + WPA2 encryption
with the TKIP/AES-CCMP encryption method is preconfigured.
This setting allows you to use WLAN devices that support WPA
(TKIP) or WPA2 (AES-CCMP) or both methods.
Change this preset WLAN network key as soon as possible.
Enter a new WLAN key in the FRITZ!Box user interface.
Recommendation
Set the most secure encryption method supported by your
WLAN device in the FRITZ!Box.
If your WLAN device supports WPA2:
•
•
•
If your WLAN device supports WPA, but not WPA2:
•
Enable WPA encryption.
Select the WPA mode "WPA2 (CCMP)" or "WPA+WPA2".
Replace the WPA network key with a new, unique value.
Enable WPA encryption.
