link.
LEDs are flashing in unison, but dimly The WCB-G03H has made a valid wireless
network connection, but there is no activity on the
link. This could be caused by an Access Point
that is functioning, but not connected to the wired

2 Wireless Basics
Wireless products are based on industry standards to provide
easy-to-use and compatible high-speed wireless connectivity within
your home or business. Strictly adhering to the 802.11b and 802.11g
standards, our wireless family of products will allow you to access
the data you want, when and where you want it. No longer will you
be limited to one location or forced to run new wiring through your
home or office. You will be able to enjoy the freedom that wireless
networking delivers.
A wireless local area network (WLAN) is a cellular computer
network that transmits and receives data with radio signals instead of
wires. Wireless LANs are used increasingly in both home and office
environments, and public areas such as airports, coffee shops and
universities. Innovative ways to utilize WLAN technology are helping
people to work and communicate more efficiently. Increased mobility
and the absence of cabling and other fixed infrastructure have
proven to be beneficial for many users.
Wireless users can use the same applications they use on a
wired network. Wireless adapter cards used on laptop and desktop
systems, support the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile
network devices to link to a conventional Ethernet LAN in order to
use servers, printers or an Internet connection supplied through the
wired LAN. A Wireless Access Point (AP) is a device used to provide
this link.

The advantages of Wireless LAN are many and varied and
include:
Mobility − Productivity increases when people have
access to data in any location within the operating range of
the WLAN. Management decisions based on real-time
information can significantly improve worker efficiency.
Low Implementation Costs – WLANs (Wireless Local
Area Networks) are easy to set up, manage, change and
relocate. Networks that frequently change, both physically
and logically, can benefit from WLANs ease of
implementation. WLANs can operate in locations where
installation of wiring may be impractical.
Installation Speed and Simplicity − Installing a wireless
LAN system can be fast and easy and can eliminate the
need to pull cable through walls and ceilings.
Network Expansion − Wireless technology allows the
network to go where wires cannot go.
Reduced Cost-of-Ownership − While the initial
investment required for wireless LAN hardware might be
higher than the cost of wired LAN hardware, overall
installation expenses and life-cycle costs will be
significantly lower. Long-term cost benefits are greatest in
dynamic environments requiring frequent moves, adds,
and changes.
Scalability − Wireless Local Area Networks (WLANs) can
be configured in a variety of topologies to meet the needs
of specific applications and installations. Configurations
are easily changed and range from peer-to-peer networks
suitable for a small number of users to full infrastructure
2
networks of thousands of users that allow roaming over a
broad area.

Insert WCB-G03H into the slot of MT841, and then enter the
web-based configuration of MT841. The layout of MT841 configuring
page shown as below when you first log in.
The left part of the page is wizard column, and you can
enter the web page of configuration or management
through the hyperlink in wizard column.
The right part of the page is the practical domain of
configuration and management.

Click the WLAN of Basic in the Wizard Column to set the
WLAN configuration.

Figure 3-2 Wireless Configuration
The illustration of this page as below:
SSID: The SSID identifies members of Service Set. If the
SSID is changed, all other devices on the wireless network
must use the same SSID.
Channel: The available channel for the MT841 is
depending on the local regulatory environment. Remember
that all devices communicating with the device must use
the same channel (and use the same SSID). Use the drop
down menu to select the channel used for your wireless
LAN.
Module: MT841 provides multiple wireless bands, select
the suitable band from the drop-down menu.
WEP Method: WEP (Wireless encryption Protocol)
encryption can be enabled for security and privacy. WEP
encrypts the data portion of each frame transmitted from
2
the wireless adapter using one of the predefined keys. If
network Security is not used, click None, otherwise select
WEP or WPA-PSK.
WEP Key: The MT841 offers 64, 128, or 256-bit
encryption with four keys available, select an
encryption level from the drop-down menu on the right,
and then enter the proper-length key.
WPA-PSK: Wi-Fi Protected Access was designed to
provide improved data encryption, perceived as weak
in WEP, and to provide user authentication, largely
nonexistent in WEP. There are two kinds of arithmetic:
TKIP (Temporal Key Integrity Protocol) and AES
(Advanced Encryption Standard), select arithmetic
from the drop-down menu on the right, and then enter
the proper-length key.
WLAN connections: Select enable option, then the
WALN connection will be enabled with above settings,
otherwise it will be disabled.
SSID Hidden: Select enable option, and then the SSID will
be hided and can not be viewed by WLAN clients. It is to
enable or disable SSID Hidden.
Click the <Apply> button to save the settings while finished the
modification.

4 WEP Glossary
The following WEP parameters are be defined:
Wireless Band − Select the environment you are configuring.
Authentication − Select different authentication levels to
manage the data transmission.
Open System − Using an open system with WEP enabled
means the access point and wireless stations encrypt only the data
in each packet. WEP is not used for the purpose of authentication,
that is, encryption does not prevent any station from associating with
the access point.
Share Key − With this setting only stations using a shared key
encryption identified by the access point are allowed to associate
with it. Shared key WEP prohibits non-WEP WLAN stations from
associating with the access point. Shared key WEP uses encryption
for both data and authentication.
802.1X − Authenticator − controls the physical access to the
network based on the authentication status of the client. The
authenticator acts as an intermediary (proxy) between the client and
the authentication server, requesting identity information from the
client, verifying that information with the authentication server, and
relaying a response to the client.
WPA − A new security feature, Wi-Fi Protected Access
authorizes and identifies users based on a secret key that changes
automatically at a regular interval. WPA uses TKIP (Temporal Key
1
Integrity Protocol) to change the temporal key every 10,000 packets
(a packet is a kind of message transmitted over a network.) This
insures much greater security than the standard WEP security.
WEP − Wired Equivalent Privacy. You can select to [Enable] or
[Disable] WEP.
WEP Key Type − Select HexValue, and use Key Table for
HexValue to define a HexValue.
WEP Key Size − 64-bit, 128-bit, 152-bit length WEP encryption.
Valid Key − Provides 4 groups of options respectively.
Key Table for HexValue − A HexValue is strictly defined
according to the WEP encryption level (WEP Key Size). The
HexValue consists of the numbers from 0-9 and letters A-F. Each
encryption level requires a different number of HexValues digits as
follows:
64-bit encryption, type in 10 hexadecimal digits in the
QuickKey String field
128-bit encryption, type in 26 hexadecimal digits
152-bit encryption, type in 58 hexadecimal digits
Type in 4 hexadecimal values in the spaces provided. Use the
Valid Index drop-down menu to select the number of the HexValue
key (Group Index) to activate the key.
Caution:
If you have made encryption operation in [Open System], you will have to change
the password if you switch to [Share Key] mode. Otherwise the network adapter
cannot access the AP.
