• 802.1X—requires mutual authentication between a client
station and the router by including a RADIUS-based
authentication server. Information about the RADIUS
server such as its IP address, port and key must be
entered. WEP encryption is also enabled and the
encryption strength must also be selected.
• WPA—(Wi-Fi Protected Access)— usually used for the larger
Enterprise environment, it uses a RADIUS server and TKIP
(Temporal Key Integrity Protocol) encryption (instead of
WEP encryption which is disabled). TKIP uses128-bit
dynamic session keys (per user, per session, and per
packet keys).
• WPA-PSK (Wi-Fi Protected Access – Pre-Shared Key)—
WPA for home and SOHO environments also using the
same strong TKIP encryption, per-packet key construction,
and key management that WPA provides in the enterprise
environment. The main difference is that the password is
entered manually. A group re-key interval time is also
required.
• WPA2 (Wi-Fi Protected Access 2)—second generation of
WPA which uses AES (Advanced Encryption Standard)
instead of TKIP as its encryption method. Network re-auth
interval is the time in which another key needs to be
dynamically issued.
• WPA2-PSK (Wi-Fi Protected Access 2 – Pre-Shared Key)—
suitable for home and SOHO environments, it also uses
AES encryption and requires you to enter a password and
an re-key interval time.
• Mixed WPA2 / WPA—during transitional times for upgrades
in the enterprise environment, this mixed authentication
method allows “upgraded” and users not yet “upgraded” to
access the network via the router. RADIUS server
information must be entered for WPA and a as well as a
group re-key interval time. Both TKIP and AES are used.
• Mixed WPA2 / WPA-PSK—useful during transitional times
for upgrades in the home or SOHO environment, a pre-
shared key must be entered along with the group re-key
interval time. Both TKIP and AES are also used.
