Encryption
Recommendation
FRITZ!Box Fon WLAN 7270
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+WPA2".
– Replace the WPA network key with a new, unique
value.
If your WLAN adapter supports neither the WPA nor the
WPA2 mechanism:
– Enable WEP encryption.
– Replace the WLAN key with a new, unique value.
We strongly recommend the use of a WLAN adapter that
supports WPA or WPA2 (for instance, the FRITZ!WLAN USB
Stick N). WEP is out of date and data encrypted with WEP
can be deciphered within minutes.
