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 Wir eless Access Point links your 802.11g or 802.11b 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
The auto-sensing capability of the Wireless Access Point allows packet transmission up to 54Mbps for maximum throughput, or automatic speed reduction to lower speeds when the environment does not permit maximum throughput.

This Chapter covers the physical installation of the Wireless Access Point.
Requirements
Requirements:
TCP/IP network
Ethernet cable with RJ-45 co nnectors
Installed Wireless network adapter for each PC that will be wirelessly connected to the
network
Procedure
1. Select a suitable location for the installation of your Wireless Access Point. To maximize reliability and performance, follow these guidelines:
Use an elevated location, such as wall mounted or on the top of a cubicle.
Place the Wireless Access Point near the center of your wireless coverage area.
If possible, ensure there are no thick walls or metal shielding between the Wireless
Access Point and Wireless stations. Under ideal conditions, the Wireless Access Point has a range of around 150 meters (450 feet). The range is reduced, and transmission speed is lower, if there are any obstructions between Wireless devices.
Figure 4: Installation Diagram
2. Use a standard LAN cable to connect the “Ethernet” port on the Wireless Access Po int to a 10/100BaseT hub on your LAN.

Wireless Access Point User Guide
3. Connect the supplied power adapter to the Wireless Access Point and a convenient power outlet, and power up.
4. Check the LEDs:
The Status LED should flash, then turn OFF.
The Power, WLAN, and LAN LED should be ON.
For more information, refer to Front Panel LEDs in Chapter 1.

Chapter 3
Access Point Setup

This Chapter provides details of the Setup process for Basic Operation of your Wireless Access Point.
Overview
This chapter describes the setup procedure to make the Wireless Access Point a valid device on your LAN, and to function as an Access Point for your Wireless Stations.
Wireless Stations may also require configuration. For details, see Chapter 4 - Wireless Station Configuration.
The Wireless Access Point can be configured using either the supplied Windows utility or your Web Browser
Setup using the Windows Utility
A simple Windows setup utility is supplied on the CD-ROM. This utility can be used to assign a suitable IP address to the Wireless Access Point. Using this utility is recommended, because it can locate the Wireless Access Point even if it has an invalid IP address.
Installation
1. Insert the supplied CD-ROM in your drive.
2. If the utility does not start automatically, run the SETUP program in the root folder.
3. Follow the prompts to complete the installation.
Main Screen
Start the program by using the icon created by the setup program.
When run, the program searches the network for all active Wireless Access Points, then
lists them on screen, as shown by the example below.

Setup Procedure
Before commencing, install the Wireless Access Point in your LAN, as described previously.
1. Check the Wireless Access Point to determine its Default Name. This is shown on a label on the base or rear, and is in the following format:
SCxxxxxx Where xxxxxx is a set of 6 Hex characters ( 0 ~ 9, and A ~ F ).
2. Use a PC which is already connected to your LAN, either by a wired connection or an­other Access Point.
Until the Wireless Access Point is configured, establishing a Wireless connection to it
may be not possible. If your LAN contains a Router or Routers, ensure the PC used for configuration is on
the same LAN segment as the Wireless Access Point.
3. Start your Web browser.
4. In the Address box, enter "HTTP://" and the Default Name of the Wireless Access Point e.g.
HTTP://SC2D631A
5. You should then see a login prompt, which will ask for a User Name and Password.

Setup
If you can't connect:
It is likely that your PC’s IP address is incompatible with the Wireless Access Point’s IP address. This can happen if your LAN does not have a DHCP Server. The default IP address of the Wireless Access Point is 192.168.0.228, with a Network Mask of 255.255.255.0.
If your PC’s IP address is not compatible with this, you must change your PC’s IP address to an unused value in the range 192.168.0.1 ~ 192.168.0.254, with a Network Mask of 255.255.255.0. See Appendix C - Windows TCP/IP for details for this procedure.

Repeater Access Point
- act as a repeater for another Access Point. If selected, you must provide the address (MAC ad dress) of the other Access Point (Remote AP).
This is not required unless the Operating Mode is "Client Access Point" or "Repeater Access Point". In either of these modes, you must provide the MAC address of the other AP in this field. You can either enter the MAC address directly, or, if the other AP is on-line, you can click the "Select AP" button and select from a list of available APs.
If "Automatic" is selected, the Wireless Access Point will self-select a Wireless Channel.
If you experience interference (shown by lost connections and/or slow data transfers) you may need to experiment with different channels to see which Channel is the best.
This displays the current channel used by the Access Point.
SSID
Broadcast SSID
Enter the desired SSID. Wireless Stations must use the same SSID. Note: The SSID is case sensitive. If Enabled, the SSID will be broadcast to all Wireless Stations. Sta-

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.

Radius-based MAC Authentication
Radius MAC Authentication provides for MAC address checking which is centralized on your Radius server. If you don't have a Radius Server, you cannot use this feature.
This screen will look different depending on the current security setting. If you have already provided the address of your Radius server, you won't be prompted for it again.

TKIP + 64 bit WEP - Unicast (point-to-point) transmis­sions are encrypted using TKIP, and multicast (broadcast) transmissions are encrypted using 64 bit WEP.
TKIP + 128 bit WEP - Unicast (point-to-point) transmis­sions are encrypted using TKIP, and multicast (broadcast) transmissions are encrypted using 128 bit WEP.
AES - CCMP - Unicast (point-to-point) transmissions and multicast (broadcast) transmissions are encrypted using AES - CCMP.

Wireless Access Point User Guide
2.4GHz Security Settings - WPA-802.1x
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 required.
All data transmission is encrypted using the WPA standard. Keys are automatically
generated, so no key input is required.
