How to make a home using WiFi router?

With the advent of laptops, and later other mobile devices wire that traditionally have linked PC in the network, began to interfere.Lightweight laptop can be moved from place to place, but it's not very convenient to do when it is attached to the network cable.Quite naturally was the idea of ​​uniting computers using radio waves in the manner of a radiotelephone.There were first achievements wireless standards Wi-Fi.

Now the technology is firmly established in our lives, as the home can make any WiFi.It's so convenient to be able to quickly connect to the Internet from anywhere in the apartment, office, the park or coffee shop.Modern Wi-Fi standards allow you to work on a network at a rate sufficient for listening to music and watching movies online.It can be said that the wireless Wi-Fi technology give a person freedom of information.

makes the network Wi-Fi

To make the network will need two types of equipment: an access point wi-fi, and clients that will connect to the network.Clients can be laptops, PDAs, mobile devices that support Wi-Fi, as well as desktop computers, which have a internal or external Wi-Fi adapter.The access point is usually - a router that supports wireless networks, such as D-Link DIR 300.

First you need to configure the router itself, as do WiFi at home with distribution to several clients without it will not.The device must be connected to a computer via twisted pair.To control the device using the web interface, which can be opened in a browser.If the setting is made for the first time, then find a username and password may be in the documentation for the router, but if not, it needs to know the owner of the machine.

When the authorization is to open the router management page where you need to find a section dedicated to Wi-Fi.Here you can enable or disable a wireless connection, set the SSID of the network, which will help to protect it from outside interference, and choose a way to encrypt traffic and security key.

When the Wi-Fi router is set to, you can begin to configure the client.As a rule, there's nothing complicated: If the wireless adapter works fine, and it installed the software, the list of available networks will be displayed in the network control center, or in a special window on Windows XP.On detection of a new network can usually be found from the tray Windows.After selecting the network from the list, you can connect to it by entering the SSID of the network and, depending on the encryption, security key.

question may arise about how to make a home without WiFi router.Such a method is, but it can be used to connect only two computers, it is not supported by all adapters speed and thus will be less than with a router.

How does it work?

How to WiFi home almost clear, but how does it work?We construct all the technology on the access point to which clients connect.Each point is creating its network and has its own transmission parameters such as a network identifier, an encryption method (if applicable), the encryption key.Each network has a coverage area, i.e. the area around the access point to which it can be recognized by the signal from the clients, on the other hand, customers may be recognized by the signal from the access point.Wi-Fi access point has a range of up to 300 meters.However, this value is "perfect", it is reduced in practice due to various obstacles.

Apparently, Wi-Fi technology has sufficiently low long-range.But progress does not stand still, and gradually introduced wireless networking standard, WiMAX.WiMAX access point has a radius of action is measured in kilometers, and perhaps in the future, this technology will provide internet access the most remote corners of the planet.
