Wireless USB Adapter
Introduction
Thank you for purchasing the IEEE 802.11b/g or 802.11n Wireless USB Adapter. This
Wireless Adapter is easy to use and easy to setup. If you have been tired of dealing with all
those messy wires to connect a laptop or PC to office or home network, this Wireless adapter is
an ideal access solution for wireless Internet connection.
A typical Internet access application for the USB wireless adapter is shown as the following
figure:
There are two different ways to access Internet:
1. With a wireless adaptor, receiving and transferring signal via a wireless router, then
passed to an ADSL modem, then to local ISP (Internet service supplier) through a
telephone line.
2. With a wireless adaptor, receiving and transferring signal via local AP (Access Point) or
so called Hotpoint directly.
Tips: An 802.11 LAN is based on a cellular architecture where the system is subdivided into
cells, where each cell (called Basic Service Set or BSS) is controlled by a Base Station
(called Access Point, or in short AP).
Package Contents:

Installation
To install the driver of the USB adapter, please use administrator user account to login before
the following steps:
Tips: the latest original drivers can be down loaded from the website of Ralink chipset
manufacturer. The current website is http://www.ralinktech.com/support.php To find a
correct driver, please identify the chipset type applied in the adapter you have.
1. For a 54Mbps 802.11b/g or a 150Mbps or 300Mbps 802.11n adapter, double click
Ralink_***.exe program, which is located in the driver folder in the installation disc. Such
as: G:\WiFi Driver\Windows Driver\ RT2070_RT307X.exe.
Notes: Because Ralink often updates software
software,, the drivers contained in the disc
might be changed without prior notice.
2. Follow the instructions and prompts of the “InstallShield Wizard” to finish the driver
installation:
a. Select the “I accept the terms of the license agreements”, then click the “Next”.
b. There shows a setup type window, you can select “Install driver only” or “Install driver

Tips
Tips::
1).The Windows XP utilizes a "Wireless Zero Configuration( WZC)" Service built into
the operating system. Many wireless network adapter cards utilize this service.
2). Ralink- the chipset manufacturer has developed a utility for setting up wireless
connection. If you select this item, you can switch between the Windows XP’s WZC
service and the Ralink WLAN utility service later.
c. Click the “Install” to confirm the installation, there shows the installation progress.
d. Click “finish” to finish the driver installation.

Hardware Installation Notes:
1) Before installation, please check the power supply voltage first, to ensure normal power
supply is 5V;
2) Make sure the module pins correctly installed (VCC 5V; DATA +; DATA-; GND; TX
Control; EXTERNAL LED);
3) Make sure that the antenna does not allow users to replace or demolition;
4) Make ensure that the antenna placed natural vertical antenna installation;
5) Make ensure the module shield completeness;
6) Note that the wireless module installed from away the body 20cm.
Wireless Connection
1. After finishing driver installation, insert the USB adapter to Notebook or PC that
supports USB 2.0/1.1 interface.
Remarks: Make sure to connect the adapter to an USB port on your computer
directly rather than an USB hub. Although it might work when connecting with an
USB hub, the likelihood of configuration problems will be higher.
2.
The system shows a wireless utility icon in the Windows system tray, which locates in
the bottom-right corner of your computer screen, and pops up a message that indicates
a new hardware is found and installed, something like this:
Should the service " Wireless Zero Configuration ( WZC)" be applied.

Double-click the utility icon or right click the icon and then select “View Available
Wireless Networks” to launch the utility, the Wireless Network Connection window
appears and displays your wireless network listed with the SSID you chose.
Notes: Before configuring your WiFi access, you need to have your network’s SSID
(service set identifier), security key and authentication type handy. Check the
documentation coming with your router, ask your network administrator to get the
information.
2.
If you don't see your network, click “Refresh network list” in the upper left corner. If you
are locating within the valid range of hotspots or wireless routers, all available networks
will be recognized and listed automatically. Click your preferred network, and then click
“Connect” in the lower right corner.
3.
If the network security key hasn’t been inputted before, Windows XP prompts you to
enter the network’s security key to access the wanted SSID. Type the encryption key
that you wrote down earlier in both the Network key and Confirm network key boxes,
and then click “Connect”.
Tips: If there are free hotspots, simply select the network you want from the list
displayed, then click Connecting. It tries to launch your Internet browser—you should

be connected to the Internet.
If there is a pay hotspot, signing in or up will require either to enter your login
information-if you‘re an existing customer, or to enter your credit card information for
payment, it is just decided by you. Then clicking the Connecting, your default Internet
browser will launch and take you to the service provider’s login page. Most providers
have very simple and step-by-step instructions for you to sign up and then to be
connected. Another way to access the service provider’s login page is to simply
launch your Internet browser, if there’s a pay network available, you’ll be taken
directly to the login page.
Should the service of Ralink wireless connection utility be applied.
After the installation of Ralink utility, the system shows a special wireless utility icon in the
Windows system tray, which locates in the bottom-right corner of your computer screen:
When an USB wireless adapter is inserted into an USB 2.0/1.1 port of Notebook or PC,
the icon changes colors according to the wireless signal quality.
1.
Double-click the icon or right click the icon and then select “Launch Config Utility” to
launch the utility, the RaUI window appears like:
The Ralink wireless utility starts in compact mode as shown above, provides profile
management, the available networks listing, a statistical counter display, Wi-Fi
multimedia (WMM), protected Wi-Fi setup, Cisco compatible extensions (CCX), call
admission control (CAC), radio controls, Ralink driver/utility information, and help
functions. Clicking the expanding icon

Tips for Wi-Fi users
With a Wi-Fi connection, you can roam about 150 m around the access point (depends on
different environment), so find a spot where you can work without any interruption. Then see
how much work you can do, such as:
�
Easily and quickly receive and transmit files within your local network — no problem
for big files.
�
Access your email and surf the web with the same speed as that connected with
network cables.
�
Synchronize data between devices.
�
Take advantage of wireless printing — send files directly from your laptop PC to a
wireless printer over Wi-Fi connection.
Warning
Wi-Fi offers greater speed and range than Bluetooth, but it drains your portable device
batteries a lot faster than Bluetooth does. In fact, if you use a Wi-Fi connection regularly on
your laptop PC, you'll undoubtedly notice that you need to recharge more often. If you need to

conserve battery life — on a long trip for example — turn off your Wi-Fi connection when you
don't actually need it.
Security
Because wireless networks rely on radio signals to transmit data, they are not as secure as
wire network. Wireless networks are susceptible to viruses and breaches like eavesdropping
and need to be protected in order to be secure.
There are many security measures to safeguard wireless networks, protect the data, and
keep unauthorized users out. Hotspots, on the other hand, are often free of standard security
practices in an effort to make it easy for anyone to connect. It may be found that some pay
hotspots administered by service providers offer have some level of security, however, when
using a hotspot, it’s always a good idea to be proactive and to employ security measures of
your own.
