1. Choose your wireless equipment
The first step is to  make sure that you have the equipment you need. As you're looking for  products in stores or on the Internet, you might notice that you can  choose equipment that supports three different wireless networking  technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g,  because it offers excellent performance and is compatible with almost  everything.

A wireless router
The  router converts the signals coming across your Internet connection into  a wireless broadcast, sort of like a cordless phone base station. Be  sure to get a wireless router, and not a wireless access point.
A wireless network adapter
Network  adapters wirelessly connect your computer to your wireless router. If  you have a newer computer you may already have wireless capabilities  built in. If this is the case, then you will not need a wireless network  adapter. If you need to purchase an adapter for a desktop computer, buy  a USB wireless network adapter. If you have a laptop, buy a PC  card-based network adapter. Make sure that you have one adapter for  every computer on your network.
Note: To make  setup easy, choose a network adapter made by the same vendor that made  your wireless router. For example, if you find a good price on a Linksys  router, choose a Linksys network adapter to go with it. To make  shopping even easier, buy a bundle, such as those available from D-Link,  Netgear, Linksys, Microsoft, and Buffalo. If you have a desktop  computer, make sure that you have an available USB port to plug the  wireless network adapter into. If you don't have any open USB ports, buy  a hub to add additional ports.                
2. Connect your wireless router
Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.
First, locate your cable modem or DSL modem and unplug it to turn it off.
Next,  connect your wireless router to your modem. Your modem should stay  connected directly to the Internet. Later, after you've hooked  everything up, your computer will wirelessly connect to your router, and  the router will send communications through your modem to the Internet.
Link Removed due to 404 ErrorNext, connect your router to your modem:
Note:  The instructions below apply to a Linksys wireless router. The ports on  your router may be labeled differently, and the images may look  different on your router. Check the documentation that came with your  equipment for additional assistance.                
- If you currently have your computer connected directly to your modem:  Unplug the network cable from the back of your computer, and plug it  into the port labeled Internet, WAN, or WLAN on the back of your router.
- If you do not currently have a computer connected to the Internet:  Plug one end of a network cable (included with your router) into your  modem, and plug the other end of the network cable into the Internet,  WAN, or WLAN port on your wireless router.
- If you currently have your computer connected to a router:  Unplug the network cable connected to the Internet, WAN, or WLAN port  from your current router, and plug this end of the cable into the  Internet, WAN, or WLAN port on your wireless router. Then, unplug any  other network cables, and plug them into the available ports on your  wireless router. You no longer need your original router, because your  new wireless router replaces it.
Link Removed due to 404 ErrorNext,  plug in and turn on your cable or DSL modem. Wait a few minutes to give  it time to connect to the Internet, and then plug in and turn on your  wireless router. After a minute, the Internet, WAN, or WLAN light on  your wireless router should light up, indicating that it has  successfully connected to your modem.
3. Configure your wireless router
Link Removed due to 404 ErrorUsing  the network cable that came with your wireless router, you should  temporarily connect your computer to one of the open network ports on  your wireless router (any port that isn't labeled Internet, WAN, or  WLAN). If you need to, turn your computer on. It should automatically  connect to your router.
Next, open Internet Explorer and type in the address to configure your router.
You  might be prompted for a password. The address and password you use will  vary depending on what type of router you have, so refer to the  instructions included with your router.
As a quick reference, this table shows the default addresses, usernames, and passwords for some common router manufacturers.

Internet  Explorer will show your router's configuration page. Most of the  default settings should be fine, but you should configure three things:
- Your wireless network name, known as the SSID.  This name identifies your network. You should choose something unique  that none of your neighbors will be using.
- Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network.  For most routers, you will provide a passphrase that your router uses  to generate several keys. Make sure your passphrase is unique and long  (you don't need to memorize it).
- Your administrative password, which controls your wireless network.  Just like any other password, it should not be a word that you can find  in the dictionary, and it should be a combination of letters, numbers,  and symbols. Be sure you can remember this password, because you'll need  it if you ever have to change your router's settings.
                    The exact steps you follow to  configure these settings will vary depending on the type of router you  have. After each configuration setting, be sure to click 
Save Settings, 
Apply, or 
OK to save your changes.                
Now, you should disconnect the network cable from your computer.
4. Connect your computers to the wireless network
Add a device or computer to a network
                                          Depending on the operating system your computer is  running and whether your network devices support newer technologies, the  steps for adding a device or computer to the network will vary. For  more information about setting up a network, see 
Setting up a home network.
     
To add a wireless computer running Windows 7 or Windows Vista Service Pack 2 by using a push button
         If your router supports Windows Connect Now (WCN), or Wi‑Fi Protected Setup (WPS), you can add a computer to the network by following these steps:
       
-          Turn on the computer.
-                                Open Connect to a Network by right-clicking the network icon (Link Removed due to 404 Error or Link Removed due to 404 Error) in the notification area.         
 A list of networks currently available is displayed.
-          Click your network, and then click Connect.
-          Instead of typing a security key or passphrase,  press the Wi‑Fi Protected Setup (WPS) button on the router. The router  will automatically set up the computer to connect to the network and  apply the network's security settings.
 
 Windows Connect Now helps you add a computer to the network.
Note
                             WCN sets up the network connection with security turned on by default. You can change the security settings later if desired.
                
     
To add a wireless computer running Windows 7, Windows Vista, or Windows XP by using a USB flash drive
         If your settings are saved to a USB flash drive,  you can use the flash drive to add computers to your network. To do so,  follow these steps:
       
-          Log on to the computer that you want to add to the network.
-          Plug the USB flash drive into a USB port on the computer.
-          For a computer running Windows 7 or Windows Vista, in the AutoPlay dialog box, click Wireless Network Setup Wizard. 
 For a computer running Windows XP, in the USB flash drive dialog box, click Wireless Network Setup Wizard.
 You might be prompted to restart the computer.
Note
                             To save your wireless network settings to a  USB flash drive, insert a USB flash drive into the computer, and then  follow these steps:
