802.11i/WPA and WEP. The function of the encryption is to ensure the security
level of cable-bound LANs also in Wireless LANs.

Use encryption on the data transferred in the WLAN. Activate the strong-
est possible encryption available to you ((802.11i with AES, WPA or WEP)
and enter the appropriate keys or passphrases into the access point and
the WLAN clients.
Regularly change the WEP keys in your access points. The passphrases for
802.11i or WPA do not have to be changed regularly as new keys are gen-
erated for each connection anyway. This is not the only reason that the
encryption with 802.11i/AES or WPA/TKIP is so much more secure than
the now aged WEP method.
If the data is of a high security nature, you can further improve the encryp-
tion by additionally authenticating the client with the 802.1x method
('802.1x / EAP' →page 43) or activate an additional encryption of the
WLAN connection as used for VPN tunnels ('IPSec over WLAN'
→page 44). In special cases, a combination of these two mechanisms is
possible.
Further details to WLAN security and the used encoding methods can
be found in the LCOS reference manual.
Please take note of the information in the box "Standard WEP encryp-
tion".
