Chapter 1
Introduction
This Chapter provides an overview of the Wireless Access Point's features
and capabilities.
Congratulations on the purchase of your new Wireless Access Point. The Wireless Access
Point links your Wireless Stations to your wired LAN. The Wireless stations and devices on
the wired LAN are then on the same network, and can communicate with each other without
regard for whether they are connected to the network via a Wireless or wired connection.
Figure 1: Wireless Access Point
Features of your Wireless Access Point
The Wireless Access Point incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
x Standards Compliant. The Wireless Access Point complies with the IEEE802.11g and
IEEE802.11n draft 2.0 specifications for Wireless LANs.
x Supports 11n Wireless Stations. The 802.11n Draft standard provides for backward
compatibility with the 802.11b standard, so 802.11n, 802.11b and 802.11g Wireless sta-
tions can be used simultaneously.
x Bridge Mode Support. The Wireless Access Point can operate in Bridge Mode, con-
necting to another Access Point. Both PTP (Point to Point) and PTMP (Point to Multi-
Point) Bridge modes are supported.
And you can even use both Bridge Mode and Access Point Mode simultaneously!
1
Wireless Access Point User Guide
x WPS Support. WPS (Wi-Fi Protected Setup) can simplify the process of connecting any
device to the wireless network by using the push button configuration (PBC) on the Wire-
less Access Point, or entering a 8-digit PIN code if there's no button.
x DHCP Client Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Wireless Access Point can act as a
DHCP Client, and obtain an IP address and related information from your existing DHPC
Server.
x Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded
easily, using only your Web Browser.
x PoE Support. You can use PoE (Power over Ethernet) to provide power to the Wireless
Access Point, so only a single cable connection is required.
Security Features
x Virtual APs. For maximum flexibility, wireless security settings are stored in Virtual AP.
Up to 4 Virtual APs can be defined and used as any time.
x Multiple BSSIDs.Because each Virtual AP has it own SSID and beacon, and up to 4
Virtual APs can be active simultaneously, multiple SSIDs are supported. Different clients
can connect to the Wireless Access Point using different SSIDs, with different security
settings.
x Virtual APs Isolation. If desired, PCs and devices connecting to different Virtual APs
can be isolated from each other.
x VLAN Support. The 802.1Q VLAN standard is supported, allowing traffic from differ-
ent sources to be segmented. Combined with the multiple SSID feature, this provides a
powerful tool to control access to your LAN.
x WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit
128 Bit, and 152 Bit keys are supported.
x WPA support. Support for WPA is included. WPA is more secure than WEP, and
should be used if possible. Both TKIP and AES encryption methods are supported.
x 802.1x Support. Support for 802.1x mode is included, providing for the industrial-
strength wireless security of 802.1x authentication and authorization.
x Radius Client Support. The Wireless Access Point can login to your existing Radius
Server (as a Radius client).
x Radius MAC Authentication. You can centralize the checking of Wireless Station
MAC addresses by using a Radius Server.
x Rogue AP Detection. The Wireless Access Point can detect unauthorized (Rouge)
Access Points on your LAN.
x Access Control. The Access Control feature can check the MAC address of Wireless
clients to ensure that only trusted Wireless Stations can use the Wireless Access Point to
gain access to your LAN.
x Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
Advanced Features
x Command Line Interface. If desired, the command line interface (CLI) can be used for
configuration. This provides the possibility of creating scripts to perform common con-
figuration changes.
2
Introduction
x Auto Configuration. The Wireless Access Point can perform self-configuration by
copying the configuration data from another Access Point. This feature is enabled by de-
fault.
x Auto Update. The Wireless Access Point can automatically update its firmware, by
downloading and installing new firmware from your FTP server.
x Radius Accounting Support. If you have a Radius Server, you can use it to provide
accounting data on Wireless clients.
x Syslog Support. If you have a Syslog Server, the Wireless Access Point can send its log
data to your Syslog Server.
x SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing
you to use a SNMP program to manage the Wireless Access Point.

If enabled, then each Wireless station using the Access Point is
invisible to other Wireless stations. In most business stations, this
setting should be Disabled.
Security Settings
Select the desired option, and then enter the settings for the selected method.
The available options are:
x None - No security is used. Anyone using the correct SSID can connect to your network.
x WEP - The 802.11b standard. Data is encrypted before transmission, but the encryption
system is not very strong.
x WPA-PSK - Like WEP, data is encrypted before transmission. WPA is more secure than
WEP, and should be used if possible. The PSK (Pre-shared Key) must be entered on each
Wireless station. The 256Bit encryption key is derived from the PSK, and changes fre-
quently.
21
Wireless Access Point User Guide
x WPA2-PSK - This is a further development of WPA-PSK, and offers even greater secu-
rity, using the AES (Advanced Encryption Standard) method of encryption.
x WPA-PSK and WPA2-PSK - This method, sometimes called "Mixed Mode", allows
clients to use EITHER WPA-PSK (with TKIP) OR WPA2-PSK (with AES).
x WPA with Radius - This version of WPA requires a Radius Server on your LAN to
provide the client authentication according to the 802.1x standard. Data transmissions are
encrypted using the WPA standard.
If this option is selected:
x This Access Point must have a "client login" on the Radius Server.
x Each user must have a "user login" on the Radius Server.
x Each user's wireless client must support 802.1x and provide the login data when re-
quired.
x All data transmission is encrypted using the WPA standard. Keys are automatically
generated, so no key input is required.
x WPA2 with Radius - This version of WPA2 requires a Radius Server on your LAN to
provide the client authentication according to the 802.1x standard. Data transmissions are
encrypted using the WPA2 standard.

PC and Server Configura-
tion
This Chapter details the PC Configuration required for each PC on the local
LAN.
Overview
All Wireless Stations need to have settings which match the Wireless Access Point. These
settings depend on the mode in which the Access Point is being used.
x If using WEP or WPA-PSK, it is only necessary to ensure that each Wireless station's
settings match those of the Wireless Access Point, as described below.
x For 802.1x modes, configuration is much more complex. The Radius Server must be
configured correctly, and setup of each Wireless station is also more complex.
Using WEP
For each of the following items, each Wireless Station must have the same settings as the
Wireless Access Point.
Mode On each PC, the mode must be set to Infrastructure.
SSID (ESSID) This must match the value used on the Wireless Access Point.
The default value is wireless
Note! The SSID is case sensitive.
Wireless
Security
x Each Wireless station must be set to use WEP data encryption.
x The Key size (64 bit, 128 bit, 152 bit) must be set to match the
Access Point.
x The keys values on the PC must match the key values on the Access
Point.
Note:
On some systems, the key sizes may be shown as 40bit, 104bit, and
128bit instead of 64 bit, 128 bit and 152bit. This difference arises be-
cause the key input by the user is 24 bits less than the key size used for
encryption.

x The Pre-shared Key entered on the Access Point must also be
entered on each Wireless client.
x The Encryption method (e.g. TKIP, AES) must be set to match the
Access Point.
41
Wireless Access Point User Guide
Using WPA-Enterprise
This is the most secure and most complex system.
WPA-Enterprise mode provides greater security and centralized management, but it is more
complex to configure.

For each of the following items, each Wireless Station must have the same settings as the
Wireless Access Point.
Mode On each PC, the mode must be set to Infrastructure.
SSID (ESSID) This must match the value used on the Wireless Access Point.
The default value is wireless
Note! The SSID is case sensitive.
802.1x
Authentication
Each client must obtain a Certificate which is used for authentication for
the Radius Server.
802.1x
Encryption
Typically, EAP-TLS is used. This is a dynamic key system, so keys do
NOT have to be entered on each Wireless station.
However, you can also use a static WEP key (EAP-MD5); the Wireless
Access Point supports both methods simultaneously.
Radius Server Configuration
If using WPA-Enterprise mode, the Radius Server on your network must be configured as
follow:
x It must provide and accept Certificates for user authentication.
x There must be a Client Login for the Wireless Access Point itself.
x The Wireless Access Point will use its Default Name as its Client Login name. (How-
ever, your Radius server may ignore this and use the IP address instead.)
x The Shared Key, set on the Security Screen of the Access Point, must match the
Shared Secret value on the Radius Server.
x Encryption settings must be correct.

Troubleshooting
Overview
This chapter covers some common problems that may be encountered while using the Wireless
Access Point and some possible solutions to them. If you follow the suggested steps and the
Wireless Access Point still does not function properly, contact your dealer for further advice.
General Problems
Problem 1: Can't connect to the Wireless Access Point to configure it.
Solution 1: Check the following:
x The Wireless Access Point is properly installed, LAN connections are
OK, and it is powered ON. Check the LEDs for port status.
x Ensure that your PC and the Wireless Access Point are on the same
network segment. (If you don't have a router, this must be the case.)
x If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
x You can use the following method to determine the IP address of the
Wireless Access Point, and then try to connect using the IP address, in-
stead of the name.
To Find the Access Point's IP Address
1. Open a MS-DOS Prompt or Command Prompt Window.
2. Use the Ping command to “ping” the Wireless Access Point. Enter
ping followed by the Default Name of the Wireless Access Point.
e.g.
ping SC003318
3. Check the output of the ping command to determine the IP address of
the Wireless Access Point, as shown below.
Figure 64: Ping
If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address which is compatible with the Wireless Access Point. (If no DHCP
Server is found, the Wireless Access Point will default to an IP Address and
Mask of 192.168.0.228 and 255.255.255.0.) On Windows PCs, you can use
Control Panel-Network to check the Properties for the TCP/IP protocol.
81
Wireless Access Point User Guide
Problem 2: My PC can't connect to the LAN via the Wireless Access Point.
Solution 2 Check the following:
x The SSID and WEP settings on the PC match the settings on the Wire-
less Access Point.
x On the PC, the wireless mode is set to "Infrastructure"
x If using the Access Control feature, the PC's name and address is in the
Trusted Stations list.
x If using 802.1x mode, ensure the PC's 802.1x software is configured
correctly. See Chapter 4 for details of setup for the Windows XP 802.1x
client. If using a different client, refer to the vendor's documentation.
82
C
Appendix C
Windows TCP/IP
Overview
Normally, no changes need to be made.
x By default, the Wireless Access Point will act as a DHCP client, automatically obtaining a
suitable IP Address (and related information) from your DHCP Server.
x If using Fixed (specified) IP addresses on your LAN (instead of a DHCP Server), there is
no need to change the TCP/IP of each PC. Just configure the Wireless Access Point to
match your existing LAN.
The following sections provide details about checking the TCP/IP settings for various types of

Appendix D
About Wireless LANs
Overview
Wireless networks have their own terms and jargon. It is necessary to understand many of
these terms in order to configure and operate a Wireless LAN.
Wireless LAN Terminology
Modes
Wireless LANs can work in either of two (2) modes:
x Ad-hoc
x Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-
tions (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
SSID/ESSID
BSS/SSID
A group of Wireless Stations and a single Access Point, all using the same ID (SSID),
form a Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communi-
cate with each other. However, some Access Points allow connections from Wireless
Stations which have their SSID set to “any” or whose SSID is blank (null).
ESS/ESSID
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID),
form an Extended Service Set (ESS).
93
Wireless Access Point User Guide
Different Access Points within an ESS can use different Channels. To reduce interference,
it is recommended that adjacent Access Points SHOULD use different channels.
As Wireless Stations are physically moved through the area covered by an ESS, they will
automatically change to the Access Point which has the least interference or best perform-
ance. This capability is called Roaming. (Access Points do not have or require Roaming
capabilities.)
Channels
The Wireless Channel sets the radio frequency used for communication.
x Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. For 802.11g,
13 channels are available in the USA and Canada, but 11channels are available in North
America if using 802.11b.
x If using multiple Access Points, it is better if adjacent Access Points use different Chan-
nels to reduce interference. The recommended Channel spacing between adjacent Access
Points is 5 Channels (e.g. use Channels 1 and 6, or 6 and 11).
x In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest signal
is used. (This can only happen within an ESS.)
x If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This
is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Wireless Access Point must have the same
settings.
WPA-PSK
Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should
be used if possible. The PSK (Pre-shared Key) must be entered on each Wireless station. The
256Bit encryption key is derived from the PSK, and changes frequently.
WPA2-PSK
This is a further development of WPA-PSK, and offers even greater security, using the AES
(Advanced Encryption Standard) method of encryption.
WPA-Enterprise
This version of WPA requires a Radius Server on your LAN to provide the client authentica-
tion according to the 802.1x standard. Data transmissions are encrypted using the WPA
standard.
94
Appendix D - About Wireless LANs
If this option is used:
x The Access Point must have a "client login" on the Radius Server.
x Each user must have a "user login" on the Radius Server.
x Each user's wireless client must support 802.1x and provide the login data when required.
All data transmission is encrypted using the WPA standard. Keys are automatically generated,
so no key input is required.
802.1x
This uses the 802.1x standard for client authentication, and WEP for data encryption. If possi-
ble, you should use WPA-Enterprise instead, because WPA encryption is much stronger than
WEP encryption.
If this option is used:
x The Access Point must have a "client login" on the Radius Server.
x Each user must have a "user login" on the Radius Server.
x Each user's wireless client must support 802.1x and provide the login data when required.
x All data transmission is encrypted using the WEP standard. You only have to select the
WEP key size; the WEP key is automatically generated.

Command Line Interface
Overview
If desired, the Command Line Interface (CLI) can be used for configuration. This creates the
possibility of creating scripts to perform common configuration changes. The CLI requires a
Telnet connection to the Wireless Access Point.
Using the CLI - Telnet
1. Start your Telnet client, and establish a connection to the Access Point.
e.g.
Telnet 192.168.0.228
2. You will be prompted for the user name and password. Enter the same login name and
password as used for the HTTP (Web) interface.
The default values are admin for the User Name, and password for the Password.
3. Once connected, you can use any of the commands listed in the following Command
Reference.
