If you choose WPA as the encryption method, you have the option to set up the Access
Point to act as an 802.1X proxy, utilizing external authentication sources such as a
RADIUS server.
In 802.1X authentication, the supplicant sends access request messages along with
credentials, such as user name / password or digital certificate, to an authenticator,
which forwards the credentials to the authentication server for verification. The
supplicant (client device) remains in an unauthorized state until verification has been
received. In unauthorized state, only 802.1X traffic is allowed; all other traffic, such as
DHCP and HTTP traffic, is dropped. For its wireless interfaces, the Access Point can
serve as the authenticator communicating between the supplicant and the authenti-
cation server.
• TKIP: Temporal Key Integrity Protocol is an older
encryption algorithm that provides stronger security
than a shared WEP key, but not as strong as the newer
AES algorithm.
• AES: AES (Advanced Encryption Standard) replaces
TKIP as the default (and recommended) encryption
algorithm for modern wireless LANs.
• Auto: Auto allows both encryption algorithms to be
used on the same WLAN. When Auto is selected, the
wireless client decides whether TKIP or AES will be
used. Note however that allowing TKIP will reduce the
performance of the WLAN (as broadcast packets will
be limited to slower transfer rates), and is therefore
not recommended.
Enter a new passphrase between 8 and 32 characters
long, using any combination of printable characters
(letters, numbers, hyphens and underscores).
