Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes is implemented without the use of wires. Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrierand this implementation usually takes place at the physical level or “layer” of the network. Wireless home networks are becoming more and more popular these day. The ease of installation and the practicality of being able to surf the net anywhere in the house makes wireless home networks very attractive to internet users. Setting up a wireless home network is quite easy but you need to know some basic things about wireless networks before attempting to start the set up. You can read up more about the wireless networking protocols to help you get a better understanding of wireless networking. To set up a wireless home network you need to have broadband internet connection with a cable or DSL modem. The common set up at home is usually that of the desk top computer being plugged directly into the modem. In this tutorial we will assume that you have a laptop that you want to connect wirelessly to the PC that is connected to the internet. You need some hardware to make this possible. First you need to have a wireless router. You also need to add a USB wireless network adapter to your desk top PC and a PC card-based network adapter for your laptop computer. For obvious reasons, it is advisable to choose the same vendor for all the additional hardware you buy. Refer to the documentation that comes with your hardware for the installation process. Network cards are the backbone of any network. The Network interface card or the network card is a hardware device that allows a computer to be connected to a network, and through the network to other computers and devices. It is installed in one of the free peripheral connect interface (PCI) slots of a computer and includes a port in which the networking cable is inserted. There are different NICs for different networks even if the computer is the same. For example, if a computer is to be connected to an Ethernet LAN, it must be equipped with an Ethernet network card and if it is to be connected to a wireless LAN, a wireless network card needs to be installed.

                 When you already have all the necessary hardware installed, you can begin the set up. First you need to unplug or turn off the DSL modem then connect the wireless router to the modem. You can check the documentation that came with your hardware for assistance. When you’ve set it up your computer will wirelessly connect to your router. The next step is to configure your wireless router. With Internet Explorer you can go to your router’s configuration page. Most of the default settings there are rather safe left alone but there are some things that you need to configure. You need to choose a unique wireless network name or SSID, this will be the name of your network. Be sure that no one around that is near you is using the same name. The next step is, if your router requires it, to provide a unique passphrase that it will use to generate some keys. Then the last step to do before you are done with configuring the router is setting your administrative password. Choose a password that is not easy to guess and not too short for security reasons. Be sure to save every setting you’ve configured. The actual steps involved in configuring these settings  vary according to the kind of router you have.
