After the appearance of computers and laptops, in almost every house, the number of customers from providers increased several tens of times, since in the modern world for many life without the Internet is almost unthinkable.

To begin with, a regular information transfer protocol through a telephone connection was used, then an increase in the amount of information transmitted demanded an improvement in the quality and increase the transmission rate. There are new ways to access the Internet.

However, as before, the convenience of using laptops was minimal due to the need to connect the cable from the modem. After that, it was invented a wireless way to transfer a large amount of data on a fairly long distance, which was called Wi-Fi. In the modern world, in many major cities, you can find Wi-Fi access points and everyone can do this if you have access to the Internet and a special router.

What is Wai Fi Router for Home

Smartphones, tablets, laptops and stationary computers can be used to obtain a large amount of data. In the case of tablets and telephones, the situation is complicated by the fact that you cannot connect to the Internet to update or another task through the WAN cable.

For the convenience of using the Internet of the house began to use Wi-Fi routers. Such equipment differs from the old versions of execution by which it has a Wi-Fi module that performs connecting all devices in the field of its signal. The first models were equipped with an antenna, modern externally differ from the usual versions.

The principle of operation of this equipment is as follows:

1. There is a connection to the network via telephone or communication created for the Internet, as before.
2. The built-in module that is configured through the computer when switching through the IP address of the system, connects to the created network, it evenly distributes the maximum speed between the connected devices.

The router acts as a distributor of information.

What are the routers

The choice of router should be found thoroughly, as the features of the created wireless network will depend on it. Conditionally, all Wi-Fi-routers can be divided into the following groups:

1. ADSL - Wireless router, which is connected by ADSL. It is used if there is a WAN port under the telephone connector. It has rather great popularity, as in many cities connecting to the Internet takes place by means of a telephone cable.
2. FTTB. - The most popular version of execution that connects along twisted pair.
3. CPON / CEPON / PON - A recent version of the execution, which allows you to maintain the maximum allowable connection speed and information transmission. You can use this router only if there is a necessary connection to the provider, which is called passive optical networks.
4. 3G. - Routers that are able to conduct a distribution when connecting to the Internet through a cellular communication. In this case, the ports are not, there is a place to install a SIM card.
5. The most expensive and popular version of execution is universal. It provides for a merging of multiple connection types.

When considering this issue, we note that in 99% of cases, routers are issued providers, as they need to be correctly configured according to the protocol of their connection.

Recently, Wi-Fi routers are increasingly carried out, as they exclude the need for a long time with a cable laying to the required place.

Given the rather large radius of work and the fact that the signal passes through the walls, the router can stand anywhere.

The only snag is a computer or other device must have a receiver. All modern laptops have a built-in receiver of a similar wireless network, but stationary computers do not have it in the standard configuration.

There are several options for solving a problem with the lack of Wi-Fi receiver at a stationary computer:

1. Using an external device, which can be connected via a USB or WLAN port. Here it should be borne in mind that the USB connection has a certain limitation of the speed of information transmission. Therefore, if there is a connection with high speed at the router (associated with the features of the service provider) this method of organizing the home network is not recommended. WLAN port does not have such a hard restriction.
2. If the maternal card provides the ability to install an internal network reception unit, then you can upgrade the system unit. However, this can do it much more expensive than creating a wired home network.

As a rule, the wizard that comes to connect the Internet will recommend the most appropriate connection option.

How to choose

Despite the fact that the representative from the provider will recommend the most appropriate version of the router, in some cases you have to choose yourself. When choosing, you should pay attention to the following nuances:

1. Price - The scatter of this indicator for the equipment that is intended for use at home is very large. At the same time, the price corresponds to the stuffing: a weak level of the signal, low reliability, a small range of coating and so on. However, no washed away to take a very expensive version of the performance for the house.
2. The presence of certain ports. In most cases, it is enough to have a set of fastethernet ports. Ports that are intended to connect a gigabyte compound are often not needed, since the speed provided by the provider is often significantly lower. The only case is to create an extensive home network, but in domestic needs it is extremely rare.
3. Features Wi-Fi antennas are very important. There are two types of antenna location: internal and external. It is recommended to purchase with an external antenna, since it is possible to replace it with a more powerful version of execution if necessary. It should also be borne in mind that an antenna should work according to the 802.11n protocol to achieve a high transmission rate. Some manufacturers to reduce the cost of construction are installed other types of antennas that work at very low speeds. The frequency of operation determines the coating radius.
4. Hardware stuff - An important indicator for which few pay attention. The type of hardware filling affects the work of the home network as well as the installed "iron" on the system unit.
5. Additional features for such equipment are very limited. Often these are additional connectors, as well as embedded servers for specific programs.
6. Brand. As for the brand, there is almost nothing to say here - all manufacturers have terrible and good models. For example, TP-Link and Netgear have many models with good performance indicators. ASUS extremely rarely gives failures. But all manufacturers have models that often bring big problems. Often it is a line of budget options, since on their manufacture all manufacturers save as they can.

Also, when choosing, you can see options that are installed from acquaintances and ask them about problems with the Internet.

How to use

You can install the router anywhere. At the same time, it should not stand in the raw room, the temperature should be room, the effect of direct rays from the Sun is excluded. Install this equipment is quite simple: you just need to connect the cable from the network and all. But with the setting is increasingly harder.

Creating an access point is carried out through a computer, but the features of connecting to the Internet depend on the work of the provider. For configuration, you need the username and password of the administrator, and the provider does not provide this information to protect its servers.

Overview of the best models

You can select the following models:

1. TP-LINK TL-WR740N - an inexpensive version of execution that has a powerful antenna. The transfer rate is 150 Mbps. For most users of this speed should be quite enough. Cost - about 2500 rubles.
2. TP-LINK TL-WR841N - A more productive option that has a speed of about 300 Mbps. Two powerful antennas are installed. The cost is within 4000 rubles.

In conclusion, we note that it is possible to make Wi-Fi at home without a special router only in the case of a device, with a built-in module that is able to distribute, and not just receive a signal. Modern models of many laptops can be a point of access, and if the computer has access to the Internet, access will be visible to all devices. In some cases, the access point can be a smartphone, a tablet.

To date, perhaps, no longer meet a person who does not use the computer or does not have a PC at home. In addition, more and more services, programs needed for work and recreation, work when connecting to the Internet.

Also recently, the situation is becoming increasingly popular when there is not one apparatus in the apartment, house or office, and several (PCs, tablets, communicators, smartphones, etc.), each of which requires its separate connection to the network.

The ability to connect several devices to the Internet, while having one point of the input signal from the provider, is currently being carried out using a router or router.

The router itself represents a network device, the purpose of which is the transfer of batch data between the devices conjugates and the access point - the service provider. In addition, more expensive routers are equipped with a number of additional features, including:

• the ability to install restrictions on access to potentially dangerous for sites;
• the ability to connect a firewall;
• the ability to encrypt network access and traffic distribution;
• ordered distribution of traffic at access points, etc.

Standard router, which can often be found, both in a private house and in the office of the company, public places, is a small equipment on its dimensions, consisting of a hardware block, antennas for transmitting a Wi-Fi signal, a power supply for connecting to the power grid, Switching cords (patch cords).

Photo - Complete set and connection of the router

The standard router is capable of organizing a network by connecting 4 PCs to it by means of wired communication, as well as 5-10 devices for which Wi-Fi channels will be highlighted. However, specialists are not recommended to fully load the router, especially if this is not an expensive model of this device. Otherwise, the router can hang, not withstanding large loads.

Some models of routers can be equipped with USB ports to connect a flash media or hard disk to them. This feature will allow the use of hardware as a file server, print server, etc. In addition, individual models can also boast the support function 3G modems.

What you should pay attention to

When choosing a router, it is worth considering the following features, operating parameters of this equipment:

• to organize a home connection or network for a small office, there will be a conventional (non-professional) router from the average price range;
• requires support for IEEE 802.11g and IEEE 802.11n standards will provide data transfer rate by Wi-Fi to 600 Mbps;
• installation must support PPTP or L2TPthat will provide access to Internet communications of almost any provider.

Principle of Wireless Wi Fi Router

The principle of operation of the equipment is based on obtaining and converting the address of the recipient, which is "registered" in the information packet header for its transfer, then the path to which information is addressed to the routing table is determined. In the event that the routing table does not provide any address, the information is not accepted, discarded.

In practice, there are some other data transmission systems on the device connected to the router. For example, using the sender's address or upper header levels protocols. There are also no rare cases when the transmission of addresses as the sender and the recipient, as well as filtering the transit data transmitted data, is not rare.

How to install Wi-Fi Router: Step-by-step instructions

In order to independently connect and configure the router, you must do the following:

1. The first thing that is done to install the equipment is all communications from the router to the PC and to the Internet signal transmission unit from the provider. To do this, the Internet cable is inserted into the connector called Wan, and in one of the remaining ports insert the cable, completing with the router, the other end is designed for the Ethernet connector on the back panel of the PC. After that, turn on the power of the device.
2. Next, go to the configuration of the software of the router. Equipment setting is not typical and may differ depending on the router model and connection settings from the provider. Configuration can be performed via any browser installed on the computer (Google Chrome, Opera, Internet Explorer, etc.). To do this, go to the administrative interface of the device by entering into the address bar of the browser of the combination of numbers: 192.168.1.1. After pressing the "ENTER" key, the equipment administration window should jump out. If this does not happen, you should check the cable connection, make sure that the connection is running, then repeat the attempt.
3. The next step is to configure the Wi-Fi connection. If the router is equipped with a quick setup function, then you need to start the Quick Setup service and follow the settings of the installation wizard. Among the settings will select the following parameters: - type of preferred compound;

   - type connection to the Internet;

4. Next, you need to connect the Wi-Fi module itself. To do this, the installation wizard offers the following menu.

After the steps of the Internet, the connection must already work. However, if the Internet speed is underestimated or permanent signal loss occurs, experts recommend choosing some particular channel (from 1 to 13), saving the settings. It is also worth taking care of the access password to the connected router signal. Otherwise, unauthorized connections are possible, which will also undertake traffic and make the operation of the router slower.

After the router is connected and configured, it only remains to connect the operation of the network card to the PC or laptop and use the operation of the device from the Internet. On a laptop, you must make sure that the special key is pressed, including Wi-Fi mode. If this operation is performed, you must connect the device to the network.

To do this, on the desktop toolbar on the network icon, you can right-click, select the name of the installed network, click the "Connect" button from the Opening Menu.

Connection is similarly performed for Windows 8, for the rest of the systems, turning on the device to work on a similar scheme.

How much is a router for a computer

To date, the electronics and computer equipment market offers its customers a wide selection of routers discharging from each other as a manufacturer, so some functional features of the device. It can be routers for a home network with a few conjugate devices or industrial equipment to provide Internet access to public places, large offices. Accordingly, given the functionality of the apparatus, the cost of devices will be varied at times. Having visited the store or the online store of electrical goods, the client can choose for itself the appropriate equipment that will meet the requirements for him. At the same time, he will need to make the amount of money ranging from 1 thousand rubles. For the standard model to more than 25 thousand rubles. For professional multifunctional devices.

Once the computer connects to a Wi-Fi network, the password will not be asking for it from it. And most users this password is safely forgotten, especially if it was recorded on a piece of paper. This is not a problem exactly until you need to connect another device to the same Wiifa - for example, a phone or tablet.

I will show some proven ways to see the password that are suitable for any popular operating system (Windows 7, 8, 10).

The easiest way to find out the password from Waifa

one . Click the left mouse button on this icon in the tray.

It is located in the lower right corner of the screen, between the alphabet and the clock. Sometimes this icon hides under a small arrow.

2. In the window that appears, click right-click on the network, from which you need to know the password, and select "Properties".

3. We put a tick in "Display Input Entered" and the computer shows the wifi password in the Network Security Key field.

Another simple way

This option is a bit more complicated, but it shows all the wireless networks, to which the computer has connected, and not only active.

one . Click the right mouse button on the tray icon and select the "Network and Common Access Control Center" item.

2. A window will open on the left part of which you select "Wireless Network Management".

3. Click on the desired network right-click and select "Properties".

four . Go to the "Security" tab and put the bird near "Display Input Entered".

If there is no "Wireless Network Management" item, then click on "Changing the Adapter Settings", right over the desired connection and select "Status". In the window, click on the Wireless Network Properties button, go to the Safety tab and check the box next to "Display Entered Signs".

Pull the password through the program

There is such a wonderful free WirelessKeyView program. Thanks to her, you can see passwords from all the points to which the computer was connected. It is not necessary to install it: just download from the official site, unpack and run the program file. If WiFi points do not appear immediately, click on the icon

That's all :)

From the minuses it should be noted that some antiviruses swear on it, as the program climbs into the settings (my Kaspersky, for example, made a panic). If it does not confuse you, use on health.

Watch your password from your Wi-Fi in the router settings

This method is good in that only thanks to him you can find out the password that the computer does not know at all. For example, Windows was reinstalled, and you do not remember the password from your Waifa and now you cannot connect. So in this case the router will help.

Router - this thing that "distributes" the Internet. It looks like this:

In its settings, among other things, a password is stored. To find it, you need to connect the router to the computer through the power cord (usually it comes in the kit).

If the computer remembers the password and connects to the network, then you can not do this.

one . Open the browser (program for the Internet), in the address bar We print 192.168.1.1 and press the ENTER button on the keyboard.

Most often, after that, a login / password request appears. If this did not happen, try other addresses: 192.168.0.0, 192.168.0.1, or 192.168.1.0. But if they are not suitable, then take the router, turn it over and go to the sticker its IP address.

For example, I have no address on the sticker. Then I rewrote a router model from her (in my case Huawei HG8245A) and drove in the search engine "Huawei HG8245A IP address" in the search engine. It turned out that the default address is another, as, in fact, and login with password.

2. In the window that appears, enter the ADMIN login and the Admin password.

Usually, these data are suitable (if no one has changed specifically). But there may be other options, such as root or user. They are usually written on the router itself - on the sticker on the other side.

3. Open the Wireless tab or WLAN and are looking for a password. Often it is in Wireless Security (Security Settings or Wireless Protection).

As a rule, the password is written in the column where there is a word Key, Password or password. Often to see it, you need to take a tick.

By the way, it happens, it is written immediately when opening the router settings.

If not helped

Then you can reset all the settings of the router to the factory. But in this case it will have to configure it yourself: specify the Internet connection settings, network name and password.

To reset the settings on the router there is a small deeply related button RESET (usually it is behind).

Clear it with some sharp object for ten seconds. After that, all installations will be reset, and the router will be like new - only to configure it.
