FCC Warning statement:

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection

against harmful interference in a residential installation. This equipment generates, uses and can

radiate radio frequency energy and, if not installed and used in accordance with the instructions,

may cause harmful interference to radio communications. However, there is no guarantee that

interference will not occur in a particular installation. If this equipment does cause harmful

interference to radio or television reception, which can be determined by turning the equipment off

and on, the user is encouraged to try to correct the interference by one or more of the following

measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference.

(2) This device must accept any interference received, including interference that may cause undesired

operation.

1. This Transmitter must not be co-located or operating in conjunction with any other antenna or

transmitter.

2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled

environment. This equipment should be installed and operated with a minimum distance of 20

centimeters between the radiator and your body.

3. Any changes or modifications (including the antennas) made to this device that are not expressly

approved by the manufacturer may void the user’s authority to operate the equipment.

TRENDnet declares that TEW-604UB, (FCC ID: S9ZTEW604UB) is limited in CH1~ CH11 for 2.4 GHz

by specified firmware controlled in U.S.A.

CE Mark Warning

This is a Class B product. In a domestic environment, this product may cause radio interference, in

which case the user may be required to take adequate measures.

This transmitter must not be co-located or operation in conjunction with any other antenna or

transmitter.

Chapter 1- Wireless LAN Networking

This section provides background information on wireless LAN networking technology.

THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING

NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD

ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR.

Transmission Rate (Transfer Rate)

The adapter provides various transmission (data) rate options for you to select. Options

include Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps,

22 Mbps, 24 Mbps, 36 Mbps, 48 Mbps, 54 Mbps and 108Mbps. In most networking

scenarios, the factory default Fully Auto setting proves the most efficient. This setting allows

your adapter to operate at the maximum transmission (data) rate. When the communication

quality drops below a certain level, the adapter automatically switches to a lower

transmission (data) rate. Transmission at lower data speeds is usually more reliable.

However, when the communication quality improves again, the adapter gradually increases

the transmission (data) rate again until it reaches the highest available transmission rate.

Types of Wireless Networks

Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In

infrastructure mode, wireless devices communicate to a wired LAN via access points. Each

access point and its wireless devices are known as a Basic Service Set (BSS). An Extended

Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as

peer-to-peer mode), wireless devices communicate with each other directly and do not use

an access point. This is an Independent BSS (IBSS).

To connect to a wired network within a coverage area using access points, set the adapter

operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without

an access point, use Ad-hoc (IBSS) mode.

AD-HOC (IBSS) NETWORK

Ad-hoc mode does not require an access point or a wired network. Two or more wireless

stations communicate directly to each other. An ad-hoc network may sometimes be referred

to as an Independent Basic Service Set (IBSS).

To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID

and channel for each.

When a number of wireless stations are connected using a single access point, you have a

Basic Service Set (BSS).

In the ESS diagram below, communication is done through the access points, which relay

data packets to other wireless stations or devices connected to the wired network. Wireless

stations can then access resources, such as a printer, on the wired network.

In an ESS environment, users are able to move from one access point to another without

losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2)

the adapter automatically switches to the channel used in BSS (2).

WIRELESS LAN SECURITY

Because wireless networks are not as secure as wired networks, it is vital that security

settings are clearly understood and applied.

The list below shows the possible wireless security levels on your adapter starting with the

most secure. EAP (Extensible Authentication Protocol) is used for authentication and utilizes

dynamic WEP key exchange. EAP requires interaction with a RADIUS (Remote

Authentication Dial-In User Service) server either on the WAN or the LAN to provide

authentication service for wireless stations.

1. Wi-Fi Protected Access (WPA)

2. IEEE802.1X EAP with RADIUS Server authentication

3. WEP Encryption

4. Unique ESSID

DATA ENCRYPTION WITH WEP

The WEP (Wired Equivalent Privacy) security protocol is an encryption method designed to try

to make wireless networks as secure as wired networks. WEP encryption scrambles all data

packets transmitted between the adapter and the access point or other wireless stations to

keep network communications private. Both the wireless stations and the access points must

use the same WEP key for data encryption and decryption.

There are two ways to create WEP keys in your adapter.

•Automatic WEP key generation based on a password phrase called a passphrase.

The passphrase is case sensitive. You must use the same passphrase for all WLAN

adapters with this feature in the same WLAN.

•For WLAN adapters without the passphrase feature, you can still take advantage of

this feature by writing down the four automatically generated WEP keys from the

Security Settings screen of the wireless utility and entering them manually as the WEP

keys in the other WLAN adapter(s).

The adapter allows you to configure up to four WEP keys and only one key is used as the

default transmit key at any one time.

THE adapter SUPPORTS UP TO FOUR 64-BIT, 128-BIT, AND 152-BIT WEP KEYS. THE 152-BIT

WEP MUST COMPLY WITH THE WEP SETTING OF YOUR ACCESS POINT OR ROUTER.

DONOT ATTEMPT TO CONFIGURE OR CHANGE SECURITY SETTTINGS FOR A

NETWORK WITHOUT AUTHORIZATION AND WITHOUT CLEARLY UNDERSTANDING

THE SETTINGS YOU ARE APPLING. WITH POOR SECURITY SETTINGS, SENSITIVE

DATA YOU SEND CAN BE SEEN BY OTHERS.
