During the large-scale use of computers and the rapid development of the capabilities of computers, the functions of their use are expanding at an unprecedented rate. Now it’s not just transferring small amounts of data of the type “you to me - I tell you”, the size of the transferred files is increasing, and removable media is not the most convenient way to share a new movie or an entire series with friends. The question is how to make a local network. Whether it’s wired or wireless, it doesn’t matter. The main thing is to connect computers in one family with the ability to extremely quickly transfer data of a wide variety of sizes.
Wireless networks that combine a large number of computers are a rarity these days, as technologies that work with sufficient access and data transfer speeds to a large group of users are not yet available to the ordinary buyer. More often than not, wireless networks consist of a small number of computers. This greatly helps save on the Internet. There are several ways to "air" connection. This is Bluetooth, GPRS, Wi-Fi. Many people prefer Wi-Fi.
A local network through a router with a wireless function frees you from the routine of wires. This is not much felt on a network of two computers. And if there are at least five of them? The absence of wires allows you to freely move throughout the office where Wi-Fi is installed. The local network through the router also allows you to connect a network printer to itself and you can send a file to print from each computer in the workgroup. Conveniently. In principle, you can connect absolutely any device that supports wireless connection to a Wi-Fi router. There is one obvious drawback - although there are no wires, free movement is still limited. Budget routers allow you to move no further than 30 meters. Naturally, the more you pay for the equipment, the greater the "working" distance of the network.
On how to make a local network, there is plenty of information. When organizing a wireless network, so-called "do-it-yourself", it is important to know only the basic settings and parameters of the router. Each network has at least some name. This is a native identifier (SSID). Call your "brainchild" as you wish.
By and large, a beginner just does not need to know many settings, and it is better to leave them by default. It is worth pointing out that the settings in the Data Rate section are best left to configure the device, i.e. leave in Auto mode. This option is responsible for the data transfer rate. In order not to turn out “I wanted the best, but it turned out as always” do not change anything at your own peril and risk.
A wireless LAN through a router is often attacked by intruders. Do not lose sight of the “Security” item in the device settings. Safety is important anyway. Small hooligans can infiltrate the network and damage all computers that enter it. This is extremely unpleasant. It should be noted that the WEP encryption method is already incredibly outdated. Not only terrible hackers, but even an ordinary user can learn how to easily crack such a protection method in just half an hour. According to reviews, the best recommendations were collected by the WPA2 system. There are no defenders that can not be cracked, but this will pretty make “sweat” the attackers.
A wireless router can also serve as an Internet access point. Select the WAN menu, and the capabilities of one device expand in an instant. A local network through a router becomes more than a bunch of a couple of computers. Now it is a possibility of simultaneous wireless access to the Network.
One of the final touches is specifying the ip of the local network and the connection address. This item in most cases depends on the provider. It is at that end of the wire that they decide whether you will have a dynamic or static ip of the local network, and from which ip Internet access will be requested. There is no need for an initiative. As they say, do it. On average, organizing a simple connection between the root and computers takes no more than twenty minutes. There is nothing heavy about it. Try to arrange everything yourself and do not worry, make a mistake or spoil anything in this process is extremely difficult.
