WPA(2) Authentication
The WPA2 security mode is currently the most robust form of encryption for
wireless networks. It requires a RADIUS server to authenticate user credentials
and is a full implementation the security protocol. Use this security option for
maximum protection of your network. However, it is the least backwards
compatible with older devices.
The WPA security mode is a security subset of WPA2. It requires the presence of a
RADIUS server on your network in order to validate user credentials. This
encryption standard is slightly older than WPA2 and therefore is more compatible
with older devices.
WPA-PSK
Compatible
This field appears when you choose
WPA-PSK2
as the
Security Mode
.
Check this field to allow wireless devices using
WPA-PSK
security
mode to connect to your ZyXEL Device. The ZyXEL Device supports
WPA-PSK and WPA2-PSK simultaneously.
Encryption
If the security mode is
WPA-PSK
, the encryption mode is set to
TKIP
to enable Temporal Key Integrity Protocol (TKIP) security on your
wireless network.
If the security mode is
WPA-PSK2
and
WPA-PSK Compatible
is
disabled, the encryption mode is set to
AES
to enable Advanced
Encryption System (AES) security on your wireless network. AES
provides superior security to TKIP.
If the security mode is
WPA-PSK2
and
WPA-PSK Compatible
is
enabled, the encryption mode is set to
TKIPAES MIX
to allow both
TKIP and AES types of security in your wireless network.

The More AP Screen
The ZyXEL Device can broadcast up to four wireless network names at the same
time. This means that users can connect to the ZyXEL Device using different
SSIDs. You can secure the connection on each SSID profile so that wireless clients
connecting to the ZyXEL Device using different SSIDs cannot communicate with
each other.
This screen allows you to enable and configure multiple Basic Service Sets (BSSs)
on the ZyXEL Device.
Click
Network Settings > Wireless

Encryption
If the security mode is
WPA
, the encryption mode is set to
TKIP
to
enable Temporal Key Integrity Protocol (TKIP) security on your
wireless network.
If the security mode is
WPA2
, the encryption mode is set to
AES
to
enable Advanced Encryption System (AES) security on your wireless
network. AES provides superior security to TKIP.
ReKey Method
The ZyXEL Device can automatically disconnect a wireless station
from the wired network after a period of inactivity or after a certain
number of packets have been processed. The wireless station
needs to enter the username and password again before access to
the wired network is allowed. Select
TIME
to have the ZyXEL
Device automatically disconnects a wireless station from the wired
network after a period of inactivity.
Select
PKT
to have the ZyXEL Device automatically disconnects a
wireless station from the wired network after a certain number of
packets have been processed.
Select
NONE
if you do not want the connection between the ZyXEL
Device and a wireless station to time out.

This field indicates whether this SSID is active. A yellow bulb signifies
that this SSID is active. A gray bulb signifies that this SSID is not active.
SSID
An SSID profile is the set of parameters relating to one of the ZyXEL
Device’s BSSs. The SSID (Service Set IDentifier) identifies the Service
Set with which a wireless device is associated.
This field displays the name of the wireless profile on the network. When
a wireless client scans for an AP to associate with, this is the name that
is broadcast and seen in the wireless client utility.
Security
This field indicates the security mode of the SSID profile.

The WPS Screen
Use this screen to configure WiFi Protected Setup (WPS) on your ZyXEL Device.
WPS allows you to quickly set up a wireless network with strong security, without
having to configure security settings manually. Set up each WPS connection
between two devices. Both devices must support WPS. See
Section 6.7.6.3 on
page 147
for more information about WPS.
Note: The ZyXEL Device applies the security settings of the
SSID1
profile (see
Section 6.2 on page 125
). If you want to use the WPS feature, make sure you
have set the security mode of
SSID1
to
WPA-PSK
,
WPA2-PSK
or
No Security
.
