Protecting your WLAN
When you set up a WLAN or access an existing WLAN, always enable security features to protect your network
from unauthorized access. WLANs in public areas (hotspots) like coffee shops and airports may not provide
any security. If you are concerned about the security of your computer in a hotspot, limit your network
activities to email that is not confidential and basic Internet surfing.
Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected signals.
Take the following precautions to protect your WLAN:
●
Use a firewall.
A firewall checks both data and requests for data that are sent to your network, and discards any
suspicious items. Firewalls are available in both software and hardware. Some networks use a
combination of both types.
●
Use wireless encryption.
Wireless encryption uses security settings to encrypt and decrypt data that is transmitted over the
network. For more information, see Help and Support.
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1.
Be sure that the WLAN device is on. If the device is on, the wireless light is on. If the wireless light is off,
press the wireless button.
NOTE:
2.
Click the network status icon in the notification area, at the far right of the taskbar.
3.
Select your WLAN from the list.
4.
Click Connect.
If the WLAN is a security-enabled WLAN, you are prompted to enter a security code. Type the code, and
then click OK to complete the connection.
NOTE:
NOTE:
and then click Set up a new connection or network. A list of options is displayed, allowing you to
manually search for and connect to a network or to create a new network connection.
After the connection is made, place the mouse pointer over the network status icon in the notification area, at
the far right of the taskbar, to verify the name and status of the connection.
NOTE:
The functional range (how far your wireless signals travel) depends on WLAN implementation, router
manufacturer, and interference from other electronic devices or structural barriers such as walls and floors.
Using Bluetooth wireless devices (select models only)
A Bluetooth device provides short-range wireless communications that replace the physical cable connections
that traditionally link electronic devices such as the following:
●
Computers (desktop, notebook, PDA)
●
Phones (cellular, cordless, smart phone)
●
Imaging devices (printer, camera)

Chapter 3 Connecting to a network
On some models, the wireless light is amber when all wireless devices are off.
If no WLANs are listed, you may be out of range of a wireless router or access point.
If you do not see the WLAN you want to connect to, click Open Network and Sharing Center,
