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 coee 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 condential and basic Internet surng.

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 rewall.

A rewall 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, access Help and Support by selecting Start > 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 o,

press the wireless button.

NOTE: On some models, the wireless light is amber when all wireless devices are o.

2. Click the network status icon in the notication area, at the far right of the taskbar.

3. Select a WLAN to connect to.

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: If no WLANs are listed, you may be out of range of a wireless router or access point.

NOTE: If you do not see the WLAN you want to connect to, click Open Network and Sharing Center.

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.

5. Follow the on-screen instructions to complete the connection.

After the connection is made, place the mouse pointer over the network status icon in the notication 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 oors.
