Wireless Networking For the Absolute Newbie

If you are looking for a way to share your Internet connection, or data on different computers and devices can be done in two ways. The first solution would be to "sneaker net", which is a fancy term for manual transfer of files from one location to another, using a removable storage medium such as a USB drive. The other possible solution would be installing a wireless local area network (WLAN) at home.

Network as Area

A network refers to the interconnection between devices (such as PCs, mobile phones, laptops, etc.) and "local area", describes the area where the network is setup. That's all there is to a LAN, a group of interconnected devices, spread over an area. These interconnected devices commonly known as terminals - should be identifiable in order to have easy access to shared network resources (such as an Internet connection, a file or printer).

Second , there must be a network device - usually a network switch or router - to the interconnections between devices on the network. The routers are common in wireless networks, while the switches are usually found in cable networks.


Meanwhile, the job is done, his aim is the same - to allow different terminals to share resources such as documents, printers, etc. and communicate with each other through the network.

Go Wireless

In general, the design of your home network, you can choose either a wired or wireless. Wireless networks are becoming increasingly common in urban households, where multiple users need simultaneous access to shared resources such as an Internet connection or printer. Offers many advantages over a wired network - the main mobility.

What you need?

To configure a wireless network, all you need is a router - a network device through the terminals are connected to the network. When buying a wireless router, make sure your router is compatible with at least IEEE 802.11 a / b / g. Almost every wireless router is compatible with this standard, however, the following letters of digits (802.11) may be different.

These letters (a, b, g, etc.) mean different bandwidth (or frequency ranges), supported by the device. We recommend that your router is compatible with at least the above three bandwidths, which would give greater flexibility to configure your router and will help overcome interruptions in the wireless signals. Before buying a router, make sure to allow connections through a 10/100 Mbps cable Ethernet (LAN), if you want to share access to some devices can only connect via a network cable - for example, if you want to connect a desktop PC, without using a wireless USB adapter.

Setting up the Environment

It is recommended that you place the router in a central position in the house. In this way the WLAN is accessible from all sides, with consistent signal strength throughout the house. Many people, however, choose to place the router close to your desktop PC, in order to avoid tangles.

Configuring Your Router

Once you have determined the location of your router, turn it on and connect to the network adapter on your computer using the supplied network cable to your router package.

Once your computer is connected to the router, you need to configure your WLAN. The easiest way is to use the installation CD that came with the router, and simply follow the setup wizard.

Another way is through the integrated router - in the administrative portal. This portal can be accessed via the Web browser, and is usually located at: https: // However, it is advised to check the address on the router's user manual - if your portal is in a different direction.

Once you type in the address of your router's administrative portal and hit Enter, you will see a pop-up authentication box prompts you to enter your user name and password. In most cases, both the user name and password are "admin" (lowercase). See the manual in case another set of credentials required for authentication.

Management portal, offers a high level of control over the configuration of your network compared with the configuration wizard available on the installation CD. As a word of warning - you should be absolutely sure about the changes you make to the administrative portal. However, in case something goes wrong, you can always choose to restart the router and start all over again.

Secure Your WLAN

The first step, and recommended more important is to change the default password management portal. The reason for this is, the routers default settings are usually good - and once known potential attackers detect the router, you can try to change your 'admin'password before having the opportunity. Your router administrator portal provides a secure page where you can change the admin password and control options related to WLAN security. Once you have changed, go ahead and enable wireless encryption on the router. There are two common types of wireless encryption: Wired Equivalent Privacy (WEP) and Wi -Fi Protected Access (WPA), the latter is considered safer compared to the previous. Then, enter the password (or phrase) that allow users to access the WLAN. If you skip the creation of a password, the connection to the Internet can be used by anyone.

For added security, select the option that prevents the router from broadcasting its Service Set Identifier (SSID). Thus, the WLAN displayed as "Unnamed Network" everyone - including you - and anyone who tries to connect to it will be asked to enter the SSID (ie the network name) of the WLAN. Once you have completed the establishment of security settings, click save and wait for the router to reboot automatically.

File Sharing

The following instructions are specific to Windows XP SP3. However, the process is almost the same with small variations in later versions of Windows.

Start by opening "My Computer" and looking for the file (or folder) you want to share on the network. Assuming you have enabled sharing on your PC and want to share your "My Pictures" folder, simply open "My Documents" and right click on the folder icon called "My Pictures ". On the shortcut menu, click "Sharing and Security" menu. This opens the Properties box for that folder. In the Sharing tab, move the mouse pointer to the second box and click "Network Setup Wizard."

This wizard guides you through the steps, and you can choose to continue with the default options at every step and click "Next. " Once the wizard completes, click "Finish " and the unit is ready to share the folder and its contents in your WLAN.

Back in the "Sharing" tab of "Properties" dialog, check "Share this folder on the network" and give your shared folder a name. This name will be visible to all users who have access to the folder on the network. Also, if you do not want the contents of the folder is changed by the network, then it is recommended to read-only folder. Once done, click OK.

To check if the folder has been shared successfully, type "/ /" in the address bar followed by the name of your computer and click "Go "(or strike "Enter" on your keyboard). Use the same address that you just typed in the address bar (/ /YourPCsName/) to access this folder from any other computer on the WLAN.
