Chapter 1 - Introduction

Wireless Network Basics

A wireless network system offers a great number of advantages over a traditional
wired system. Wireless networks are more flexible, are easier to setup and manage,
and are often more cost effective than their wired equivalent.

Using radio frequency (RF) technology, wireless networks transmit and receive data
over the air, minimizing the need for wired connections. Wireless networks combine
data connectivity with user mobility, and, through simplified configuration, enable
movable networks.

With wireless networks, users can access shared information without looking for a
place to plug in, and network managers can set up or augment networks without
installing or moving wires. Wireless networks offer the following productivity,
convenience, and cost advantages over traditional wired networks:

Mobility – Wireless network systems can provide their users with access to real­time information anywhere within their organization. This mobility supports
productivity and service opportunities not possible with wired networks.

Installation Speed and Simplicity - Installing a wireless network system can be
fast and easy and can eliminate the need to pull cable through walls and ceilings.

Installation Flexibility - Wireless technology allows the network to go where wires
cannot go.

Multi-Tech Systems, Inc. Wireless Network Adapter User Guide 5

Chapter 1 - Introduction

Reduced Cost-of-Ownership - While the initial investment required for wireless
network hardware might be higher than the cost of wired network hardware, overall
installation expenses and life-cycle costs will be significantly lower. Long-term cost
benefits are greatest in dynamic environments requiring frequent moves, add-ons, and
changes.

Scalability - Wireless network systems 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 networks of thousands of users that allows roaming over a
broad area.

Safety

USB equipment is designed with the utmost care for the safety of those who install
and use it. However, special attention must be paid to the dangers of electric shock
and static electricity when working with electrical equipment. All guidelines of this
manual and of the computer manufacturer must, therefore, be allowed at all times to
ensure the safe use of the equipment.

Achieving Optimal Performance

Minimize the Number of Barriers

The number of walls, ceilings, and other objects that the wireless signal must pass
through limit the range of wireless network communications. Position your Access
Points, Residential Gateways, and computers so that the number of barriers is
minimized.

Minimize the Degree of Angles among the Access Points, Residential
Gateways, And Computers

Try to position the Access Points and Adapters so that the signal will travel straight
through a wall or ceiling for better reception.

If a 45-degree angle exists between an Access Point and a PC with a wall that is .5
meters thick, this 45-degree angle can appear to be almost 1 meter
degree angle, the barrier can appear to be over 14 meters thick.

Consider the Type of Barrier

Try to position Access Points, Residential Gateways, and Computers so that the
signal passes through drywall or open doorways. Other materials, such as solid metal
or aluminum studs, may have a negative effect on range.

Position the Antenna for Optimal Performance

The antenna can be adjusted to help improve performance.

Minimize the Amount of Distance from Electrical Devices

Try to maintain a distance of at least 1-2 meters from devices that generate RF
noise, like microwaves, monitors, electric motors, etc.

Chapter 3 – Configuration Utility

Network Mode

Two modes are available. The default is Infrastructure.

Ad Hoc - This is the 802.11 peer-to-peer mode of operation. In 802.11Ad

Hoc only one wireless cell is supported for each different SSID.
Communication is Client-to-Client without the use of an Access Point. 802.11
Ad Hoc networking uses the same SSID for establishing the wireless
connection.

Infrastructure - This mode of operation requires an 802.11 Access Point. All
communication is done via the Access Point, which relays packets to other
wireless Clients in the BSS as well as to nodes on a wired network such as
Ethernet.

Preamble

Two different Preambles are available. The default is Long.

Long Preamble - The mandatory supported Long Preamble inter-operates
with the current 1 Mbit/s and 2 Mbit/s DSSS specification (as described in
IEEE Std 802.11).

Short Preamble - The optional Short Preamble is intended for applications
where maximum throughput are desired and interoperability with legacy and
non-short-preamble capable equipment is not a consideration. That is, the
Short Preamble is intended to be used only in networks of like equipment, all
of which can handle the optional mode.

TX Rate

The TX Rate is the transmission rate at which the data packets are
transmitted. You can set this to these fixed values: 1Mbps, 2 Mbps, 5.5 Mbps
or 11 Mbps. The default is Auto.

Update Button

This button becomes active only when one of the fields has been changed.
Click this button to apply the changes to the driver and to save them to the

Encryption Tab

You may desire an additional measure of security on your wireless network.
Additional security can be set on the Encryption Tab.

Configuration Utility with the Encryption Tab Selected

Additional security can be achieved by using WEP (Wired Equivalent Privacy)
encryption. WEP encrypts each frame transmitted from the radio using one of the
Keys entered from this panel.

When an encrypted frame is received, it will be accepted only if it decrypts
correctly, and this will happen only if the receiver has the same WEP Key used by
the transmitter.

Encryption (WEP)

Choose either 64 bit or 128 bit from the drop down list box. The default is 128
bit.

WEP Key Entry

Select either a password (Passphrase) or a key (Manual Entry) for your
WEP encryption.

Create with Passphrase – Enter a password in this field.

Manual Entry - Use this field to manually enter the key code. This may be

necessary if you wish to match a key in a different vendor’s product. Note:
The numbers cannot be all zeroes.

Multi-Tech Systems, Inc. Wireless Network Adapter User Guide 20

Chapter 3 – Configuration Utility

WEP Key to Use

Select a key and then enter the keys in the corresponding fields.

Mode

There are two options. The default is Mandatory.
Mandatory Mode – This mode is the WEP encryption that should be used.

The other station also needs to use WEP encryption in order to establish a
communication with your station. This mode is required for compliance with
the IEEE 802.11b standard.

Optional Mode - This mode allows your station to communicate with other
stations that may or may not use WEP encryption.

Authentication Type

There are two options. The default is Open System.

Open System – If the Access Point is using Open System authentication,

then the wireless adapter will need to be set to the same authentication.
Shared Key – This authentication is available only if WEP encryption is

enabled. Shared Key authentication supports authentication of hosts as either
a member of a group that shares a secret key or a member of those without a
shared secret key. Shared Key authentication requires the use of WEP in order
to share the key without transmitting the secret key in the open.

Setting Sharing Levels of Access

After the sharing utility is set up, you can set the access level to your files that others
will have. Access can be set for a particular file(s) or disk drive(s) as well as all files
and drives.

Types of Access

Full Allows others on your network the to open, read, write,

save, copy, move, and delete files on the disk or in the
folder.

Read-Only Allows others on your network to lonely open and read

the files on the disk or in the folder.

Depends on
Password

The process for setting levels of access to files and drives are the same.

1. Using the Windows Explorer or the icon My Computer on your desktop,

navigate to the disk drive or folder you want to share.

2. Right-click on the disk drive or folder icon and select Sharing.

3. Select Share As to set the parameters for sharing this particular disk drive or

folder.

4. In the Share Name box, enter any name that helps you to identify the disk drive

or folder you are sharing. Note that entering the name of the location or file may
help especially as more resources on your network are shared.

5. The Comment box is optional. You could use this field to list the type of access or

names of those who have access.

6. Access Type sets the level of access allowed (full, read-only, or depend on

password)

7. The Passwords field allows you to apply a level of security to your shared drives

and folders. Other users on your network will be required to enter the password
you designate here before they can access the drive or folder. You can set two
levels of security by adding a second level password. Leaving the Password boxes
empty gives everyone on the network access to the drive or folder.

8. Click OK to continue. You will be prompted to enter the password(s) you provided

for verification. Retype the password(s) just as you entered them the first time.

9. The drive or folder can now be accessed from another computer on your network.

• Double-click the desktop or Windows Explorer icon My Computer.

• Navigate to the computer with the shared drive or folder (use the Computer

Name to identify it - see the Computer Identification section above), and
double-click. The shared drives or folders display. Double-click on one. If a
password is required, the user will be prompted for the password.

To make this process easier, Windows allows you to map shared drives and folders to
a drive letter on another computer. For example:

On the computer where you will be accessing a shared folder from another
computer, go to the icon My Computer and right-click. Select Map Network

Drive where you will then be able to assign an available drive letter. If you check
Reconnect at logon, Windows will make this network drive available each time

you start your computer.
