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
The auto-sensing capability of the Wireless Access Point allows packet transmission up to
300Mbps for maximum throughput, or automatic speed reduction to lower speeds when the
environment does not permit maximum throughput.
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 sta-
tions can be used simultaneously.
•Speeds to 300Mbps. All speeds up to the 802.11n maximum of 300Mbps are supported.

•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!
•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.
•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.
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 confi-
guration changes.

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.
•WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless
Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge
modes are supported.

Setup using a Web Browser
Your Browser must support JavaScript. The configuration program has been tested on the
following browsers:
•Netscape V4.08 or later
•Internet Explorer V4 or later
Setup Procedure
Before commencing, install the Wireless Access Point in your LAN, as described previously.
1. Use a PC which is already connected to your LAN, either by a wired connection or anoth-
er 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.
•The TEW-636APB is configured as DHCP for the default IP Address setting.
2. Start your Web browser. (Note: If you have changed the default IP Address assigned
to the TEW-636APB, make sure to enter the correct IP Address).
3. Open your web browser, type HTTP://SCXXXXXX,in the Address bar, and then press Enter.
XXXXXX represents the last 6 digits of the Mac Address. You can find the Mac Address
on the bottom of the router or enter "HTTP://" and the IP Address of the TEW-636APB,
as in this example, which uses the TEW-636APB's IP Address: HTTP://192.168.0.228
4. You should then see a login prompt, which will ask for a User Name and Password.
Enter admin for the User Name, and password for the Password.
These are the default values. The password can and should be changed. Always enter the
current user name and password, as set on the Admin Login screen.
Figure 5: Password Dialog
5. You will then see the Status screen, which displays the current settings and status. No data
input is possible on this screen. See Chapter 5 for details of the Status screen.

ronment. Details of these screens and settings are described in the following sections of
this chapter.
•System - Basic and Advanced settings
•Wireless - Basic, Advanced, Access Control, Radius Server, Virtual APs & WIFI
Protected Setup.
7. You may also wish to set the admin password and administration connection options.
These are on the Admin Login screen accessed from the Management menu. See Chapter
6 for details of the screens and features available on the Management menu.
8. Use the Apply and Reboot buttons on the menu to apply your changes and restart the
Wireless Access Point.
Setup is now complete.
Wireless stations must now be set to match the Wireless Access Point. See Chapter 4 for
details.
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 0.0.0.0,. The TEW-636APB
will receive an IP Address from the LANs DHCP server automatically. Using a
Router with DHCP server enable or a DHCP server will allow the Wireless Access
Point to receive an IP Address.
