II PRELIMINARY WU830G
Section 1:Overview
Congratulations on purchasing the Motorola Wireless
USB Adapter WU830G.
With the WU830G, your laptop or desktop computer is free to join
and enjoy all the benefits of an 802.11g wireless home or small office
network. Once connected, you can access a single broadband
connecti on wit h ever yone else on the network. You can al s o share
files, pictures, peripherals, printers, and more. You’ll need one
WU830G for each computer.
Features
The WU830G complies with the 802.11b and the new, nearly
5-times-faster, 802.11g wireless standard. With Wi-Fi
Access (WPA) included, your wireless connections are robust and
secure, giving you the confidence to communicate without fear that
the signal could be compromised.
After installing the USB adapter, you’ll have the ability to wirelessly
connect to your network to: send and receive emails, to print
documents, or game online from your computer.
With the ever-increasing number of wireless Hotspots, you’ll be
accessing the Internet and keeping up with your email in airports,
hotels, coffee shops, and convention centers.

an Internet connection on your network. A sample Local Area
Network (LAN) is shown below:
Graphic of a LAN w ith the WU830G
connected to a laptop computer
In the example above, the Internet communicates with the modem,
which in turn communicates with the router. The router acts as the
gateway to your network, sending information to whichever device
asks for information. In this example, the USB adapter enables your
notebook computer to be part of the wireless network.
Wireless Connections
Your wireless USB adapter uses a radio transmission technology
defined by the Institute of Electrical and Electronics Engineers (IEEE)
called 802.11 Wireless Fidelity (Wi-Fi). Th is standard is subdivided
into distinct categories of speed and the frequency spectrum used,
designated by the lower case letter after the standard.
SECTION 1
For example, your USB adapter can work with both the ‘b’ and ‘g’
specifications. The 802.11b specification transmits data rates up to
11 Mbps while the 802.11 g specification transmits data rates up to
54 Mbps. Both standards operate in the 2.4 GHz range. These are
theoretical speeds so your performance may vary.
A Word About Data Rates: Data rate is the speed at which individual bits of data flow through
a channel. It is not the same speed at which entire files are uploaded or downloaded. These
speeds will vary, and are often less than the maximum data rate. Upload and download
speeds are affected by several factors including, but not limited to: the capacity of and the
services offered by your cable operator or broadband service provider, channel capacity,
network traffic, computer equipment, type of server, number of connections to server, and
availability of Internet router(s).

Section 2:Installation
Before You Begi n
You need to collect information so that you can setup your WU830G
correctly. Depending upon where you are connecting, the type of
information required is divided between business (enterprise users)
and home settings (small office/home office).
Also, you need to consider the type of security to enable for your
wireless connection. A discussion of the types of security available
follows this section.
Enterprise Users
Obtain the fol low i ng infor m ation from your network admini s tr at or :
Network names (SSID) of the specific wireless networks to which
you are going to co nn ect.
W PA (Wi-Fi Protected Access) wireless network key information
(may inclu de n etwor k au th enti c ati o n ty p e, encr yption typ e,
network key) for any WPA enabled networks to which you want to
connect.
WEP (Wire d Eq ui val e nt Pr i vacy ) wir eless networ k k ey in for mation
(network key) for any WEP en abled network s to w hi ch y ou want
to connect.
For Microsoft Windows® networking, the customer name and
workgro up name.
For a network account, the domain name, a user name, and a
password.
An IP addre ss (if not using a DHCP server).
Networks connected to an authentication server, if any.
WU830G PRELIMINARY 2-1
Section 2
Security Options
Installation
Small Office/Home Office Users
The access point that communicates with the WU830G has a
pre-assigned networ k name (SSID) that th e WU8 3 0G rec o gni zes
upon startup.
If you are setting up a new wireless network and want to use
WEP security, use any string of characters for the network key. If
this feature is enabled on the wir eless network, you’ll use the
same network key for your WU830G.
If you are connecting to an existing WEP enabled network, obtain
the network key from the access point.
If you are connecting to a WPA-enabled access point, obtain the
WPA (Wi-Fi Protected Access) wireless network key information
(network auth en ti cation type, encryption typ e, net w ork key) fr om
the access point.
The WU830G is designed for bo th th e hom e us er an d busi n ess .
WPA (Wi-Fi Protected Access) protocol is designed into the chipset.
WPA is a powerful, standards-based, interoperable security
technology for wireless local area networks (the subset of the future
IEEE Std 802.11i standard) that encrypts data sent over radio waves.
The WPA protocol was developed to overcome the weaknesses of
the WEP (Wired Equivalent Privacy) protocol. Both protocols require
the use of network key information, and either protocol can be
enabled or disabled , depending on the type of netw ork connection
being made.
Various options are av ai lable for select ing network authentic ati o n an d
data encryption. It is important for you to understand these options
when deciding which (if any) security protocol to use.
Security Example
If you want to use a more secure protocol, the wireless network to
which you are connecting must also support that protocol. For
example, you decide to enable WPA-PSK on your WU830G, a good
choice because of the robust security WPA-PSK offers. However, the
slightly older wireless network you want to connect to only supports
WEP, which means that you cannot use WPA (and should use WEP)
because the security protocols must match between the network
adapter and the access point.
