Before you connect your computer to a network that is not wireless, the computer must have a network cable connected to it.
To connect a network cable:
|NOTE: Insert the cable connector until it clicks into place, and then gently pull the cable to ensure that it is securely attached.|
|NOTE: Do not use a network cable with a telephone wall connector.|
The Microsoft® Windows® XP operating system provides a Network Setup Wizard to guide you through the process of sharing files, printers, or an Internet connection between computers in a home or small office.
|NOTE: Selecting the connection method labeled This computer connects directly to the Internet enables the integrated firewall provided with Windows XP Service Pack 2 (SP2).|
A WLAN is a series of interconnected computers that communicate with each other over the air waves rather than through a network cable connected to each computer. In a WLAN, a radio communications device called an access point or wireless router connects network computers and provides Internet, or network, access. The access point or wireless router and the wireless network card in the computer communicate by broadcasting data from their antennas over the air waves.
Before you can set up a WLAN, you need:
Depending on what you selected when you purchased your computer, the computer has a variety of configurations. To confirm that your computer has a wireless network card and to determine the type of card, use one of the following:
If Wireless Network Connection does not appear under LAN or High-Speed Internet, you may not have a wireless network card.
If Wireless Network Connection appears, you have a wireless network card. To view detailed information about the wireless network card:
|NOTE: If your computer is set to the Classic Start menu option, you can view network connections by clicking the Start button, pointing to Settings, and then pointing to Network Connections. If Wireless Network Connection does not appear, you may not have a wireless network card.|
The order confirmation that you received when you ordered your computer lists the hardware and software that shipped with your computer.
Contact your Internet service provider (ISP) to obtain specific information about the connection requirements for your broadband modem.
|NOTE: Wait for a minimum of 5 minutes after disconnecting your broadband modem before you continue with the network setup.|
|NOTE: Restart your wireless equipment in the order described below to prevent a potential connection failure.|
|NOTE: Before you connect to a WLAN, ensure that you have followed the instructions in Wireless Local Area Network (WLAN).|
|NOTE: The following networking instructions do not apply to internal cards with Bluetooth® wireless technology or cellular products.|
This section provides general procedures for connecting to a network via wireless technology. Specific network names and configuration details vary. See Wireless Local Area Network (WLAN) for more information about how to prepare for connecting your computer to a WLAN.
Your wireless network card requires specific software and drivers for connecting to a network. The software is already installed if you ordered the card at the same time you ordered your computer.
|NOTE: If the software is removed or corrupted, follow the instructions in the user documentation for your wireless network card. Verify the type of wireless network card installed in your computer and then search for that name on the Dell Support website at support.dell.com. For information on the type of wireless network card that is installed in your computer, see Checking Your Wireless Network Card.|
Depending on the software installed on your computer, different wireless configuration utilities may manage your network devices:
To determine which wireless configuration utility is managing your wireless network card:
For specific information about the wireless configuration utility installed on your computer, see your wireless network documentation in the Windows Help and Support Center.
To access the Help and Support Center:
When you turn on your computer and a network (for which your computer is not configured) is detected in the area, a pop-up appears near the network icon in the notification area (in the lower-right corner of the Windows desktop).
Follow the instructions provided in any utility prompts that appear on your screen.
Once you have configured your computer for the wireless network that you selected, another pop-up notifies you that your computer is connected to that network.
Thereafter, whenever you log on to your computer within the range of the wireless network that you selected, the same pop-up notifies you of the wireless network connection.
|NOTE: If you select a secure network, you must enter a WEP or WPA key when prompted. Network security settings are unique to your network. Dell cannot provide this information.|
|NOTE: Your computer can take up to 1 minute to connect to the network.|
The wireless activity indicator provides an easy way to monitor the status of your computer's wireless devices. Right-click the Dell QuickSet icon in your taskbar to select or deselect Wireless Activity Indicator Off to turn the wireless activity indicator on or off.
The wireless activity indicator indicates whether your computer's wireless devices are enabled or disabled. When you turn the wireless networking function on or off, the wireless activity indicator changes to display the status.
For more information about the wireless activity indicator, see the Dell QuickSet Help file. For information about QuickSet and how to access the Dell QuickSet Help file, see Dell QuickSet Features.
Much like a WLAN, a Mobile Broadband network is a series of interconnected computers that communicate with each other through wireless technology. However, a Mobile Broadband network uses cellular technology and therefore provides Internet access in the same varied locations from which cellular telephone service is available. Your computer can maintain the Mobile Broadband network connection regardless of its physical location, as long as the computer remains in the service area of your cellular service provider.
|NOTE: Depending on your computer, you can use either a Mobile Broadband ExpressCard or Mini-Card, but not both, to establish a Mobile Broadband network connection.|
To set up a Mobile Broadband network connection, you need:
|NOTE: Mobile Broadband cards may not be available in all regions.|
If the utility is corrupted or deleted from your computer, see the Dell Mobile Broadband Card Utility user's guide for instructions. The user's guide is available through the Windows Help and Support Center (or on the CD that accompanied your card if you purchased it separately from your computer). To access the Help and Support Center, see Windows Help and Support Center.
Depending on what you selected when you purchased your computer, the computer has a variety of configurations. To determine your computer configuration, see one of the following:
To check your Mobile Broadband card in the Help and Support Center:
On the My Computer Information - Hardware screen, you can view the type of Mobile Broadband card installed in your computer as well as other hardware components.
|NOTE: The Mobile Broadband card is listed under Modems.|
|NOTE: These instructions only apply to Mobile Broadband ExpressCards or Mini-Cards. They do not apply to internal cards with Bluetooth® wireless technology or WLAN Mini-Cards.|
|NOTE: Before you connect to the Internet, you must activate Mobile Broadband service through your cellular service provider. For instructions and for additional information about using the Dell Mobile Broadband Card Utility, see the user's guide available through the Windows Help and Support Center. To access the Help and Support Center, see "Windows Help and Support Center" on page 13. The user's guide is also available on the Dell Support website at support.dell.com and on the CD included with your Mobile Broadband card if you purchased the card separately from your computer.|
Use the Dell Mobile Broadband Card Utility to establish and manage a Mobile Broadband network connection to the Internet:
|NOTE: The Connect button changes to the Disconnect button.|
|NOTE: If you are unable to connect to a Mobile Broadband network, ensure that you have all the components for establishing a Mobile Broadband connection (see What You Need to Establish a Mobile Broadband Network Connection), and then verify that your Mobile Broadband card is enabled by verifying the setting of the wireless switch.|
You can turn your computer's wireless devices on and off with the wireless switch on the left side of the computer (see Left Side View).
If the switch is in the "on" position, move the switch to the "off" position to disable the switch and the Mobile Broadband card. If the switch is in the "off" position, move the switch to the "on" position to enable the switch and the Dell Mobile Broadband card. For information about the wireless switch positions, see wireless switch.
To monitor the status of your wireless device, see Monitoring the Status of Wireless Network Connections Through Dell QuickSet.
The QuickSet Location Profiler helps you create profiles for accessing the Internet with your computer in your office, home, or other public places with Internet services. You can also change the way network connections are handled.
For more information about the Location Profiler, see the Dell QuickSet Help file. For information about QuickSet and how to access the Dell QuickSet Help file, see Dell QuickSet Features.
The wireless switch on your Dell computer uses the Dell Wi-Fi Catcher Network Locator to scan specifically for Wi-Fi wireless local area networks (LAN) in your vicinity.
|NOTE: For more information about the wireless switch, see wireless switch.|
To scan for Wi-Fi wireless LAN, slide and hold the switch in the "momentary" position for a few seconds. The Wi-Fi Catcher Network Locator functions regardless of whether your computer is turned on or off, in hibernate mode, or in standby mode, as long as the switch is configured through QuickSet or the BIOS (system setup program) to control Wi-Fi network connections.
Because the Wi-Fi Catcher Network Locator is disabled and not configured for use when your computer is shipped to you, you must first use Dell QuickSet to enable and configure the switch to control Wi-Fi network connections.
For more information on the Wi-Fi Catcher Network Locator and to enable the feature through QuickSet, see the Dell QuickSet Help. To access the Help file, right-click the icon in the taskbar.
The Internet Connection Firewall provides basic protection from unauthorized access to the computer while the computer is connected to the Internet. The firewall is automatically enabled when you run the Network Setup Wizard. When the firewall is enabled for a network connection, the firewall icon appears with a red background in the Network Connections section of the Control Panel.
|NOTE: Enabling the Internet Connection Firewall does not reduce the need for virus-checking software.|
