each cell (called Basic Service Set or BSS) is controlled
by a Base Station (called Access Point, or in short AP)�

thing like this:
Double-click the icon to launch the utility, there 4�

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 Survey menu item or by searching (or some other comparable choice), then choose from the list of available
SSIDs�
Notes: before conguring your WiFi access, you need
to have your network’s SSID (service set identier),
security key and authentication type handy� Check the
documentation coming with your router, ask your network 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, 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

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 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 datas, 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�
