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.

 Standards Compliant. The Wireless Access Point complies with the IEEE802.11g and

IEEE802.11n draft 2.0 specifications for Wireless LANs.

 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 sta­tions can be used simultaneously.

 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 Multi­Point) Bridge modes are supported.

And you can even use both Bridge Mode and Access Point Mode simultaneously!

 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 Wire­less Access Point, or entering a 8-digit PIN code if there's no button.

Wireless Access Point User Guide

 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.

 Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded

easily, using only your Web Browser.

 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

 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.

 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.

 Virtual APs Isolation. If desired, PCs and devices connecting to different Virtual APs

can be isolated from each other.

 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.

 WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit

128 Bit, and 152 Bit keys are supported.

 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.

 802.1x Support. Support for 802.1x mode is included, providing for the industrial-

strength wireless security of 802.1x authentication and authorization.

 Radius Client Support. The Wireless Access Point can login to your existing Radius

Server (as a Radius client).

 Radius MAC Authentication. You can centralize the checking of Wireless Station

MAC addresses by using a Radius Server.

 Rogue AP Detection. The Wireless Access Point can detect unauthorized (Rouge)

Access Points on your LAN.

 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.

 Password - protected Configuration. Optional password protection is provided to

prevent unauthorized users from modifying the configuration data and settings.

Advanced Features

 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 configu­ration changes.

 Auto Configuration. The Wireless Access Point can perform self-configuration by

copying the configuration data from another Access Point. This feature is enabled by de­fault.

 Auto Update. The Wireless Access Point can automatically update its firmware, by

downloading and installing new firmware from your FTP server.

2

Introduction

 Radius Accounting Support. If you have a Radius Server, you can use it to provide

accounting data on Wireless clients.

 Syslog Support. If you have a Syslog Server, the Wireless Access Point can send its log

data to your Syslog Server.

 SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing

you to use a SNMP program to manage the Wireless Access Point.

Package Contents

The following items should be included:

 Wireless Access Point
 Power Adapter
 3Pcs Antenna

If any of the above items are damaged or missing, please contact your dealer immediately.

Select the desired option, and then enter the settings for the selected method.
The available options are:

 None - No security is used. Anyone using the correct SSID can connect to your network.
 WEP - The 802.11b standard. Data is encrypted before transmission, but the encryption

system is not very strong.

 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.

21

Wireless Access Point User Guide

 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-PSK and WPA2-PSK - This method, sometimes called "Mixed Mode", allows

clients to use EITHER WPA-PSK (with TKIP) OR WPA2-PSK (with AES).

 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:

 This Access Point must have a "client login" on the Radius Server.
 Each user must have a "user login" on the Radius Server.
 Each user's wireless client must support 802.1x and provide the login data when re-

quired.

 All data transmission is encrypted using the WPA standard. Keys are automatically

generated, so no key input is required.

 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.

If this option is selected:

 This Access Point must have a "client login" on the Radius Server.
 Each user must authenticate on the Radius Server. This is usually done using digital

certificates.

 Each user's wireless client must support 802.1x and provide the Radius authentication

data when required.

 All data transmission is encrypted using the WPA2 standard. Keys are automatically

generated, so no key input is required.

 WPA and WPA2 with Radius - EITHER WPA or WPA2 require a Radius Server on

your LAN to provide the client authentication according to the 802.1x standard. Data
transmissions are encrypted using EITHER WPA or WPA2 standard.

If this option is selected:

 This Access Point must have a "client login" on the Radius Server.
 Each user must authenticate on the Radius Server. This is usually done using digital

certificates.

 Each user's wireless client must support 802.1x and provide the Radius authentication

data when required.

 All data transmission is encrypted using EITHER WPA or WPA2 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 encryp-

tion.
If this option is selected:

 This Access Point must have a "client login" on the Radius Server.
 Each user must have a "user login" on the Radius Server.
 Each user's wireless client must support 802.1x and provide the login data when re-

quired.

 All data transmission is encrypted using the WEP standard. You only have to select

the WEP key size; the WEP key is automatically generated.

Select "Hex" or "ASCII" depending on your input method. (All keys
are converted to Hex, ASCII input is only for convenience.)

Enter the key values you wish to use. The default key, selected by the

PC and Server Configuration

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.

 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.

 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)

Wireless
Security

This must match the value used on the Wireless Access Point.
The default value is

Note! The SSID is case sensitive.

 Each Wireless station must be set to use WEP data encryption.
 The Key size (64 bit, 128 bit, 152 bit) must be set to match the

Access Point.

 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 be­cause the key input by the user is 24 bits less than the key size used for
encryption.

Radius Server Configuration

If using WPA-Enterprise mode, the Radius Server on your network must be configured as
follow:

 It must provide and accept Certificates for user authentication.
 There must be a Client Login for the Wireless Access Point itself.

 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.)

 The Shared Key, set on the Security Screen of the Access Point, must match the

Shared Secret value on the Radius Server.

 Encryption settings must be correct.

Operation and Status

This Chapter details the operation of the Wireless Access Point and the status
screens.

Operation

Once both the Wireless Access Point and the PCs are configured, operation is automatic.

However, you may need to perform the following operations on a regular basis.

 If using the Access Control feature, update the Trusted PC database as required. (See

Access Control in Chapter 3 for details.)

 If using 802.1x mode, update the User Login data on the Windows 2000 Server, and

configure the client PCs, as required.

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:
 The Wireless Access Point is properly installed, LAN connections are

OK, and it is powered ON. Check the LEDs for port status.

 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.)

 If your PC is set to "Obtain an IP Address automatically" (DHCP

client), restart it.

 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, in­stead 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.

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.

Problem 2: My PC can't connect to the LAN via the Wireless Access Point.

Figure 64: Ping

80

Appendix B - Troubleshooting

Solution 2

Check the following:
 The SSID and WEP settings on the PC match the settings on the Wire-

less Access Point.

 On the PC, the wireless mode is set to "Infrastructure"
 If using the Access Control feature, the PC's name and address is in the

Trusted Stations list.

 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.

81

Appendix C

Windows TCP/IP

Overview

Normally, no changes need to be made.

 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.

 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
Windows, should that be necessary.

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:

 Ad-hoc
 Infrastructure

Ad-hoc Mode

Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta­tions (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 communi­cate 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).

Different Access Points within an ESS can use different Channels. To reduce interference,
it is recommended that adjacent Access Points SHOULD use different channels.

92

Appendix D - About Wireless LANs

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 perform­ance. This capability is called
capabilities.)

Roaming. (Access Points do not have or require Roaming

Channels

The Wireless Channel sets the radio frequency used for communication.
 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.

 If using multiple Access Points, it is better if adjacent Access Points use different Channels

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).

 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.)

 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 authentica­tion according to the 802.1x standard. Data transmissions are encrypted using the WPA
standard.

If this option is used:
 The Access Point must have a "client login" on the Radius Server.

93

Wireless Access Point User Guide

 Each user must have a "user login" on the Radius Server.
 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 possi­ble, you should use WPA-Enterprise instead, because WPA encryption is much stronger than
WEP encryption.

If this option is used:

 The Access Point must have a "client login" on the Radius Server.
 Each user must have a "user login" on the Radius Server.
 Each user's wireless client must support 802.1x and provide the login data when required.
 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
