How to make WiFi at home using a router?

With the advent of laptops, and later other mobile devices, the wires traditionally connected by PCs to the network began to get in the way. The light notebook can be moved from place to place, but this is not very convenient when a network cable is attached to it . The idea of combining computers with the help of radio waves in the manner of a radiotelephone became quite logical. The first developments in the standards of wireless data transmission Wi-Fi have appeared.

Now this technology has firmly entered our life, since anyone can do WiFi at home. After all, it is so convenient to be able to quickly connect to the Internet from anywhere in the apartment, office, park or cafe. Modern standards of Wi-Fi allow you to work on the network at a speed sufficient to listen to music and watch movies online. We can say that wireless Wi-Fi technology gives people information freedom.

Making a Wi-Fi network

To make a network, you need two types of equipment: a Wi-Fi access point and clients that will connect to the network. Customers can be laptops, PDAs, mobile devices that support Wi-Fi, as well as stationary computers that have an external or internal Wi-Fi adapter. An access point, as a rule, is a router that supports work in wireless networks, for example, D-Link DIR 300.

First you need to configure the router itself, as doing WiFi at home with distribution to several clients without it will not work. The device must be connected to the computer with a twisted pair. To manage this device, you use the web interface, which you can open in the browser. If the setting is made for the first time, then you can find the login and password in the documentation for the router, if not, then the owner of the device should know it.

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

When Wi-Fi is configured on the router, you can start configuring the client. Typically, there is nothing complicated: if the wireless adapter is working properly and the software is installed for it, then the list of available networks will be visible in the Network Management Center or in a special window on Windows XP. You can usually find out about finding a new network from the Windows tray. After selecting a network from the list, you can connect to it by entering the network SSID and, depending on the encryption settings, the security key.

There may be a question about how to make a WiFi home without a router. This method is there, but with it you can connect only two computers, not all adapters support it, and the speed will be less than using the router.

How it works?

How to make WiFi at home is almost understandable, but how does this system work? All technology is built on the access points with which clients are connected. Each such point creates its own network and has its own data transmission parameters, such as the network ID, the encryption method (if applicable), the encryption key. Each network has a coverage area, that is, an area around the access point where the signal from the clients can be recognized by it, and vice versa, the signal from the access point can be recognized by clients. Wi-Fi access point has a range of up to 300 meters. But this value is "ideal", in practice it decreases due to various obstacles.

Apparently, Wi-Fi technology has a fairly short range. But progress does not stand still, and wireless networks of the WiMAX standard are gradually being introduced. WiMAX access point has a radius of action, measured in kilometers and, possibly, in the future this technology will allow to provide access to the Internet the most remote corners of the planet.
