signal via local AP (Access Point) or so called Hot-
point directly�
TIPS: An 802�11 LAN is based on a cellular architec-
ture 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)�

The system pops up a message that indicates a new3�
hardware is found and installed, there shows a wireless
utility icon in the Windows system tray, which locates in
the bottom-right corner of your computer screen, some-
thing like this:
Double-click the icon to launch the utility, there4�
shows a window displaying wireless connection�
Input an SSID (wireless network name) for the wireless
network which you want to connect to� Alternatively,
looking for available networks by selecting the Site Sur-
vey menu item or by searching (or some other com-
parable choice), then choose from the list of available
SSIDs�
Notes: before conguring your WiFi access, you need
to have your network’s SSID (service set identier),
security key and authentication type handy� Check the
documentation coming with your router, ask your net-
work administrator to get the information�
According to the prompts, input the network’s se-5�
curity key to connect the wanted SSID�
If you are locating within the valid range of a hotspot,
all available networks will be recognized and listed
automatically, select the network you want and click
Connecting�
If it is 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 con-
nected to the Internet�
If it is pay hotspots, 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 instruc-
tions for you to sign up and then to be connected� An-
other 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�

Tips for Wi-Fi users
With a Wi-Fi connection you can roam about 150 feet
around the access point (depends on different environ-
ment), so nd 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 les within •
your local network – no problem for big les.
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 les di-•
rectly 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 connec-
tion regularly on your laptop PC, you’ll undoubtedly no-
tice 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 datas, they are not as secure as wire net-
work� 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 wire-
less 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�
