For example, if the wireless network has a RADIUS server, you can choose
WPA
or
WPA2
. If users do not log in to the wireless network, you can choose no
encryption,
Static WEP
,
WPA-PSK
, or
WPA2-PSK
.
Usually, you should set up the strongest encryption that every device in the
wireless network supports. For example, suppose you have a wireless network
with the ZyXEL Device and you do not have a RADIUS server. Therefore, there is
no authentication. Suppose the wireless network has two devices. Device A only
supports WEP, and device B supports WEP and WPA. Therefore, you should set up
Static WEP
in the wireless network.
Note: It is recommended that wireless networks use
WPA-PSK
,
WPA
, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select
WPA2
or
WPA2-PSK
in your ZyXEL Device, you can also select
an option (
WPA compatible
) to support WPA as well. In this case, if some of the
devices support WPA and some support WPA2, you should set up
WPA2-PSK
or
WPA2
(depending on the type of wireless network login) and select the
WPA
compatible
option in the ZyXEL Device.
Many types of encryption use a key to protect the information in the wireless
network. The longer the key, the stronger the encryption. Every device in the
wireless network must have the same key.
6.7.3
Signal Problems
Because wireless networks are radio networks, their signals are subject to
limitations of distance, interference and absorption.
Problems with distance occur when the two radios are too far apart. Problems with
interference occur when other radio waves interrupt the data signal. Interference
may come from other radio transmissions, such as military or air traffic control
communications, or from machines that are coincidental emitters such as electric
motors or microwaves. Problems with absorption occur when physical objects
(such as thick walls) are between the two radios, muffling the signal.
6.7.4
BSS
A Basic Service Set (BSS) exists when all communications between wireless
stations or between a wireless station and a wired network client go through one
access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS
traffic blocking is disabled, wireless station A and B can access the wired network
Page 132 / 404
Chapter 6 Wireless
P-661HNU-Fx User’s Guide
132
and communicate with each other. When Intra-BSS traffic blocking is enabled,
wireless station A and B can still access the wired network but cannot
communicate with each other.

MBSSID
Traditionally, you need to use different APs to configure different Basic Service
Sets (BSSs). As well as the cost of buying extra APs, there is also the possibility of
channel interference. The ZyXEL Device’s MBSSID (Multiple Basic Service Set
IDentifier) function allows you to use one access point to provide several BSSs
simultaneously. You can then assign varying QoS priorities and/or security modes
to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
6.7.5.1
Notes on Multiple BSSs
•
A maximum of eight BSSs are allowed on one AP simultaneously.
•
You must use different keys for different BSSs. If two wireless devices have
different BSSIDs (they are in different BSSs), but have the same keys, they
may hear each other’s communications (but not communicate with each other).
•
MBSSID should not replace but rather be used in conjunction with 802.1x
security.
6.7.6
WiFi Protected Setup (WPS)
Your ZyXEL Device supports WiFi Protected Setup (WPS), which is an easy way to
set up a secure wireless network. WPS is an industry standard specification,
defined by the WiFi Alliance.

WPS allows you to quickly set up a wireless network with strong security, without
having to configure security settings manually. Each WPS connection works
between two devices. Both devices must support WPS (check each device’s
documentation to make sure).
Depending on the devices you have, you can either press a button (on the device
itself, or in its configuration utility) or enter a PIN (a unique Personal Identification
Number that allows one device to authenticate the other) in each of the two
devices. When WPS is activated on a device, it has two minutes to find another
device that also has WPS activated. Then, the two devices connect and set up a
secure network by themselves.
6.7.6.1
Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each
WPS-enabled device, and allowing them to connect automatically. You do not need
to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS
PBC button in their configuration utilities instead of or in addition to the physical
button.
Take the following steps to set up WPS using the button.
1
Ensure that the two devices you want to set up are within wireless range of one
another.
2
Look for a WPS button on each device. If the device does not have one, log into its
configuration utility and locate the button (see the device’s User’s Guide for how to
do this - for the ZyXEL Device, see
Section 6.4 on page 123
).
3
Press the button on one of the devices (it doesn’t matter which). For the ZyXEL
Device you must press the WPS button for more than three seconds.
4
Within two minutes, press the button on the other device. The registrar sends the
network name (SSID) and security key through an secure connection to the
enrollee.
If you need to make sure that WPS worked, check the list of associated wireless
clients in the AP’s configuration utility. If you see the wireless client in the list,
WPS was successful.
6.7.6.2
PIN Configuration
Each WPS-enabled device has its own PIN (Personal Identification Number). This
may either be static (it cannot be changed) or dynamic (in some devices you can
generate a new PIN by clicking on a button in the configuration interface).

Use the PIN method instead of the push-button configuration (PBC) method if you
want to ensure that the connection is established between the devices you specify,
not just the first two devices to activate WPS in range of each other. However, you
need to log into the configuration interfaces of both devices to use the PIN
method.
When you use the PIN method, you must enter the PIN from one device (usually
the wireless client) into the second device (usually the Access Point or wireless
router). Then, when WPS is activated on the first device, it presents its PIN to the
second device. If the PIN matches, one device sends the network and security
information to the other, allowing it to join the network.
Take the following steps to set up a WPS connection between an access point or
wireless router (referred to here as the AP) and a client device using the PIN
method.
1
Ensure WPS is enabled on both devices.
2
Access the WPS section of the AP’s configuration interface. See the device’s User’s
Guide for how to do this.
3
Look for the client’s WPS PIN; it will be displayed either on the device, or in the
WPS section of the client’s configuration interface (see the device’s User’s Guide
for how to find the WPS PIN - for the ZyXEL Device, see
Section 6.4 on page 123
).
4
Enter the client’s PIN in the AP’s configuration interface.
5
If the client device’s configuration interface has an area for entering another
device’s PIN, you can either enter the client’s PIN in the AP, or enter the AP’s PIN
in the client - it does not matter which.
6
Start WPS on both devices within two minutes.
7
Use the configuration utility to activate WPS, not the push-button on the device
itself.
8
On a computer connected to the wireless client, try to connect to the Internet. If
you can connect, WPS was successful.
If you cannot connect, check the list of associated wireless clients in the AP’s
configuration utility. If you see the wireless client in the list, WPS was successful.

computer) connecting to the WPS-enabled AP via the PIN method.

How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role.
One device acts as the registrar (the device that supplies network and security
settings) and the other device acts as the enrollee (the device that receives
network and security settings. The registrar creates a secure EAP (Extensible
Authentication Protocol) tunnel and sends the network name (SSID) and the WPA-
PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK or WPA2-PSK
is used depends on the standards supported by the devices. If the registrar is
already part of a network, it sends the existing information. If not, it generates
the SSID and WPA(2)-PSK randomly.
