FRITZ!Box Fon WLAN 7270 140
Encryption
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.
Default Setting 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.
Recommendation If your WLAN adapter supports an encryption method that
is more secure than the one preconfigured in the
FRITZ!Box, you should select the more secure encryption
method in your FRITZ!Box.
To configure the best security settings possible with
FRITZ!Box and your WLAN adapter, please note the follow-
ing recommendations:
 If your WLAN adapter supports WPA2 in accordance
with the 802.11i standard:
– Enable WPA encryption.
– Select the WPA mode “WPA2 (CCMP)” or
“WPA+WPA2”.
– Replace the WPA network key with a new, unique
value.
 If your WLAN adapter supports the WPA mechanism,
but not the WPA2 mechanism:
– Enable WPA encryption.
– Select the WPA mode “WPA (TKIP)” or
“WPA+WPA2”.
– Replace the WPA network key with a new, unique
value.
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.
