The following table describes the labels in this screen.
8.2.1
No Security
In the
Network > Wireless LAN > AP
screen, select
No Security
from the
Security Mode
list to allow wireless devices to communicate with the ZyXEL
Device without any data encryption or authentication.

LABEL
DESCRIPTION
Wireless Setup
Enable
Wireless LAN
Click the check box to activate wireless LAN.
Channel
Selection
Select the country in which your ZyXEL Device operates. Channels
available vary according to the country you select. Set the operating
channel manually by selecting a channel from the
Channel Selection
list
or use
Auto Channel Select
to have it automatically configured.
Common Setup
Network
Name (SSID)
The SSID (Service Set IDentity) identifies the service set with which a
wireless device is associated. Wireless devices associating to the access
point (AP) must have the same SSID. Enter a descriptive name (up to 32
printable 7-bit ASCII characters) for the wireless LAN.
Note: If you are configuring the ZyXEL Device from a computer
connected to the wireless LAN and you change the ZyXEL
Device’s SSID or WEP settings, you will lose your wireless
connection when you press
Apply
to confirm. You must then
change the wireless settings of your computer to match the
ZyXEL Device’s new settings.
Hide SSID
Select this check box to hide the SSID in the outgoing beacon frame so a
station cannot obtain the SSID through scanning using a site survey tool.
Security
Mode
See the following sections for more details about this field.
MAC Filter
This shows whether the wireless devices with the MAC addresses listed are
allowed or denied to access the ZyXEL Device using this SSID.
Edit
Click this to go to the
MAC Filter
screen to configure MAC filter settings.
See
Section 8.2.6 on page 112
for more details.
QoS
Select this check box to activate Quality of Service (QoS).
Apply
Click this to save your changes.
Cancel
Click this to restore your previously saved settings.
Advanced
Setup
Click this to display the
Wireless
Advanced Setup
screen and edit more
details of your WLAN setup. See
Section 8.2.5 on page 110
for more
details.

Note: If you do not enable any wireless security on your ZyXEL Device, your network
is accessible to any wireless networking device that is within range.

WEP Encryption
Use this screen to configure and enable WEP encryption. Click
Network >
Wireless LAN
to display the
AP
screen. Select
Static WEP
from the
Security
Mode
list.
Note: WEP is extremely insecure. Its encryption can be broken by an attacker, using
widely-available software. It is strongly recommended that you use a more
effective security mechanism. Use the strongest security mechanism that all the
wireless devices in your network support. For example, use WPA-PSK or
WPA2-PSK if all your wireless devices support it, or use WPA or WPA2 if your
wireless devices support it and you have a RADIUS server. If your wireless
devices support nothing stronger than WEP, use the highest encryption level
available.

8.2.3
WPA(2)-PSK
Use this screen to configure and enable WPA(2)-PSK authentication. Click
Network > Wireless LAN
to display the
AP
screen. Select
WPA-PSK
or WPA2-
PSK
from the
Security
Mode
list.

DESCRIPTION
Security
Mode
Choose
Static WEP
from the drop-down list box.
Passphrase
Enter a passphrase (up to 32 printable characters) and click
Generate
.
The ZyXEL Device automatically generates a WEP key.
WEP Key
The WEP key is used to encrypt data. Both the ZyXEL Device and the
wireless stations must use the same WEP key for data transmission.
If you want to manually set the WEP key, enter any 5 or 13 characters
(ASCII string) or 10 or 26 hexadecimal characters ("0-9", "A-F") for a 64-
bit or 128-bit WEP key respectively.
Table 29
Network > Wireless LAN > AP: WPA(2)-PSK
LABEL
DESCRIPTION
Security Mode
Choose
WPA-PSK
or
WPA2-PSK
from the drop-down list box.
Pre-Shared Key
The encryption mechanisms used for
WPA(2)
and
WPA(2)-PSK
are
the same. The only difference between the two is that
WPA(2)-PSK
uses a simple common password, instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters
(including spaces and symbols).
WPA Group Key
Update Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA(2)-PSK
key management) or
RADIUS
server (if using WPA(2)
key management) sends a new group key out to all clients. The re-
keying process is the WPA(2) equivalent of automatically changing the
WEP key for an AP and all stations in a WLAN on a periodic basis.

WPA
,
WPA2
or

WPA Compatible
This check box is available only when you select
WPA2-PSK
or
WPA2
in the
Security Mode
field.
Select the check box to have both WPA-PSK and WPA wireless clients
be able to communicate with the ZyXEL Device even when the ZyXEL
Device is using WPA2-PSK or WPA2.
ReAuthentication
Timer
Specify how often wireless stations have to resend usernames and
passwords in order to stay connected. Enter a time interval between
10 and 9999 seconds.
Note: If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server has
priority.
Idle Timeout
The ZyXEL Device automatically disconnects a wireless station from
the wired network after a period of inactivity. The wireless station
needs to enter the username and password again before access to the
wired network is allowed.
WPA Group Key
Update Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA(2)-PSK
key management) or
RADIUS
server (if using WPA(2)
key management) sends a new group key out to all clients. The re-
keying process is the WPA(2) equivalent of automatically changing the
WEP key for an AP and all stations in a WLAN on a periodic basis.
