What is a WiFi router and why is it needed?

Recently, the question becomes more urgent: "What is a WiFi router and why is it needed?" It is difficult to imagine the life of a modern person without wireless networks, and without such a router it is impossible to implement them. So first we'll find out what kind of device it is, and we'll figure out how to work with it.

What it is?

First of all, let's define what WiFi router is. This is a network device that allows you to transfer data. And as with wires, and without them. In most cases, it is equipped with four conventional ports for connecting a twisted pair. An antenna for working with WiFi is installed separately. Such a constructive solution makes it possible to organize a small local computer network at home or in a small office without problems. A little more difficult will be in the conditions of a large company, but, as practice shows, there will be no problems with a competent approach. Some of the more advanced devices allow you to connect flash drives for storing information and a 3G-modem in case there is no data transmission on the wires.

Customize

After receiving an answer to what a WiFi router is, let's look at its configuration. It consists of two steps: connecting and setting the necessary parameters. The first of them performs the following manipulations:

• Connect the incoming twisted pair from the provider.
• We install the power supply into the socket, and the wire from it to the corresponding socket of the router.
• The cable that comes with the kit is connected to one of the 4 ports of a personal computer.

Setting the required parameters consists of the following:

• We turn on the router with the button on the back and wait for the download to finish.
• We launch any of the installed browsers on the personal computer and enter the address: "192.168.1.1". Then press "Enter".
• The next step is to enter two parameters - login and password. This information is included in the operating instructions. For example, if you need to configure a WiFi router D-link, then you need to enter "admin" in each of them.
• Go to the section "Wireless networks". Select the protection method "WPA2", set the name of the connection and the password for access to it. Save the changes. In this case, the router will need to reboot.

In most cases, manipulations are sufficient to organize a local computer network using a router. Next, turn off the personal computer, if necessary, and proceed to the next stage - the connection of devices. This can be tablets, smartphones, personal computers, TVs or satellite receivers.

Connecting

Regardless of which WiFi router is used, the connection setup algorithm on each such device is the same. To start, the wireless network adapter turns on. Then, the available connections are scanned. Then select the one whose name was set in the previous step. If the protection is set, you will need to enter a password. After that, access to network resources is obtained.

Results

Within the framework of this material, an answer was given to what a WiFi router And why it is needed. This device, which allows you to easily organize a small local area network. Most often it is used at home or in small offices. To adjust it is not difficult. Connect to it - even more so. Therefore, this is a simple and reliable solution for those who want to make an Internet connection with minimal costs.
