Configuring a wireless router

For help in configuring a wireless router, see the information provided by your router manufacturer or your
ISP.
NOTE: It is recommended that you initially connect your new wireless computer to the router by using the
network cable provided with the router. When the computer successfully connects to the Internet, disconnect
the cable, and access the Internet through your wireless network.

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, 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 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 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.
