Hello, dear visitors! Decided to buy a new Wi-Fi Router? Great idea! In this publication, we will tell you how to choose a WiFi router for home, to pay attention to when choosing a router and how not to be disappointed in the purchase. We have already told you to pay attention to and how not to choose. We even wrote an article as correct in the car. It's time and home Wi-Fi routerbut.

It's no secret that today there are a lot of manufacturers wireless routers and access points: ASUS, D-Link, Huawei., Linksys., Mikrotik., NetGear., TP-LINK., Trendnet, Ubiquiti., Upvel., Zyxel. other. And already models of routers and Wi-Fi access points for each manufacturer can be counted several dozen. What router to choose for home among all this manifold? Do I need to overpay for famous brands, modern innovations and progressive stuffing? Let's deal with together!

In one of our articles, we have already told, and what is the main principle of his work. We want to immediately clarify the difference between Wi-Fi Router and Wi-Fi Point Access. And then in stores routers can be called points of access, and vice versa. The first difference between the router from the access point is the presence of network ports on the router. And this is not a job, since the task of a simple access point is to expand the network coverage area, not the distribution of the Internet on the device.

Everything WiFi Points Access is designed to increase the network coverage area. That is, to organize a full-fledged network using an access point will not work (no desired ports). WiFi router (He is a router) is the same wireless access point, but with the possibility of networking. Any router can act as a switch because it has LAN ports for connecting a laptop or computer by network cable (). What is this network ports, we will now show. Here's what the standard Wi-Fi router looks like:

As you can see, there is nothing complicated in it. First of all, you need to understand for which Internet connections you want to choose and buy a Wi-Fi router. After all, the connection technologies are somewhat and here you need to know exactly what type of Internet is installed with you. Or what type you plan to use in the future. We have already told about different types Internet connections in our article. Here are three basic connection protocols: Ethernet, ADSL and 3G / 4G..

Tip! Many providers place the recommended models of routers on their sites. It will not be superfluous and check the compatibility of the router with your Internet connection.

First Protocol Ethernet(Basic three varieties this protocol in Russia - PPPOE, L2TP. or VPN.) Works on a network cable if your network card home Computer Or the laptop is connected to the cord from the provider, then your connection is connected and uses this communication protocol. The most popular providers providing Ethernet Access is Beeline (Beeline), Rostelecom (online), DOM.RU (Dom.ru), NetByNet, Akado Byfly TTK, Ukrtelecom other. In fact, their great many, just many of the providers we throw the channel from larger. Here is what the RJ-45 ROUTER touch the connector:

The second common communication protocol - ADSL. In Russia, the provider works with him MGTS. Here's what the WiFi router for ADSL protocol looks like (the connector looks like a telephone):

Third Popular Communication Type - 3G / 4G.. It employs such mobile operators, as MTS, Beeline, Megaphone and Skylink. On the router intended for distribution 3G / 4G. Internet there is a special USB connector:

The first thing that the buyer always draws attention is the price. Why one router costs a thousand rubles, and another four to five thousand. In many ways, the whole thing in its characteristics. But before we consider them, a couple of words about the price and the pricing market on routers.

Very often you can hear two opposite points of view. Some users home WiFi. Routers claim that overpaying for expensive models of routers does not make sense, and the second says that cheap routers are flawed, quickly break, buggy and unstable. As usual, the truth is somewhere in the middle. The absolute majority of routers are produced in China, but this does not mean that they are all bad or identical quality. That is what affects the price of the router:

• What hardware filling is installed in the router (processor, flash memory, etc.).
• Router brand.
• Hardware and software features of a particular model.

Consider all three factors affecting the price. Of course, the price is affected by the quality of the assembly and good components that are present in more expensive models of routers. But if you understand essentially and look at specific modelsYou can choose a WiFi router for the house for smaller money and not guess with its stuffing.

For example, WiFi routers of one of the leading manufacturers DlinkEspecially cheap models are often available with raw firmware, and the hardware filling of cheap routers and access points from long-standing is not designed for high performance. Eminent ASUS. It has diverse the lineupwhich includes both expensive router models and relatively budget options. The latter may not be the most the best choice. Linksys. - relatively expensive, but most of its reliable and high-quality routers. TP-LINK. - Budget manufacturer of Wi-Fi routers, product quality of this company is very controversial. You can run into poor-quality goods. Zyxel - produces a number of models for the house, which are sufficiently proven and suitable for home use. True, the price of this company is not the most democratic. Routers OT. NetGear. and Trendnet Also quite high quality and relatively cheap.

In general, each manufacturer can be running on a poor-quality model. But if you pay attention to feedback and specificationsThis probability can be strongly reduced. Hardware and software features - that's what you need to know if you want to choose a decent WiFi router for home. Largely, the price of a certain model depends on the capabilities that the router can provide. But is it necessary to extended in everyday use of the WiFi router everyday use? Let's look at how to choose a router for an apartment, from the point of view of its technical characteristics.

Basic specifications when choosing a Wi-Fi router

If you choose home router For the price and not pay attention to its characteristics, you can pay with the purchase. Some cheap wireless devices are not designed for high power and network coverage area can be several meters. In addition, low-power routers do not allow the signal through the walls or other obstacles. If you have an apartment with concrete walls or a country house with bricks, it is necessary to look at the selected model more thoroughly.

A lot of negative feedback from the owners of cheap routers, which complain that their router cuts the incoming and outgoing Internet speed via WiFi. This is due to the cheap and low-quality iron stuffing of the Wi-Fi routers. For example, if your provider gives access to a 10 megabal channel, and measuring the speed of downloading files is less than 1.25 megabytes, then it may not matter in a low-quality service, but work Wi-Fi.

In addition, cheap models of routers may freeze, bug and just turn off. Agree that constant reload the router is a very nervous occupation. Sometimes it saves it from such behavior of the device, that is, replacing the inner firmware to a newer one (fresh firmware can be found on the manufacturer's website). However, maybe not luck with expensive analogueBut the likelihood of such troubles is lower.

Now we will look at the main characteristics of routers, which should be paid to using WiFi at home. If you choose a WiFi router for the first time, then most likely do not understand specific parameters. In fact, everything is not so difficult. Above, we have already found out that any router has a port to connect the channel from the provider, LAN ports for connecting to the computer network card and the ability to distribute the Internet by wireless technology Wi-Fi. This is what the characteristics should have a modern router, if you do not know which WiFi to choose a router, then they will be enough:

1. The ability to encrypt the channel by all available encryption types - WEP., WPA, WPA2..
2. The possibility of working on all standards wireless communication – 802.11b., 802.1g, 802.11n.. N mode provides the highest speed wireless connection. It is desirable that the router knew how to work with mixed modes 802.11b / g. and 802.11b / g / n . This will allow connecting those devices that can work on 802.11n. and those older gadgets that work only on 802.11b. or 802.1g. Some models support standard 802.11AC.which theoretically allows you to work on a wireless gigabit channel. But in practice, the gigabit channel of the house is not needed, and a provider who can provide such throughput need to search.
3. Router should be able to work with protocols PPPoe, L2TP and VPN.. The first is usually enabled by default in all models, but the second and third protocols are not all. Even if you do not have a VPN or L2TP connection at home, it is not a fact that it is not necessary in the future.
4. It is desirable that the router had a removable antenna. This will increase the WiFi coverage zone if it is insufficient.
5. The number of external antennas - than them more, the better. However, a Wi-Fi router with one antenna may be enough for a small apartment or a small country house. If apartment or a private house Fully large, it is possible to install a WiFi router in the middle of a house or apartment, or buy an extra access point.
6. Volume. It is advisable to buy a router with the volume random access memory from 64 megabytes. 32 megabytes Runs may not be enough when using WiFi large quantity devices.
7. It is advisable to find a router with not the weakest. A powerful WiFi router for home is a guarantee of the stability of his work in the future. The maximum data transfer rate over Wi-Fi and signal stability during the operation of the device depends on the processor.

All modern routers have their own web interface with which you can. Worry about the absence of such an interface is not worth it. In addition, all modern models have a built-in DHCP.-server that allows you to distribute IP addresses on a computer, laptop, telephone, tablet or another gadget in automatic mode. Also most routers have built-in software firewall (Firewall), which will allow you to protect your home network from hacking by an attacker. More specific characteristic of the router can be called function WPS.. It serves to quickly connect devices that support it. For those who are interested in a quick configuration of Wi-Fi connectivity with WPS, we advise you to read our articles and settings and. We also suggest familiarizing yourself with our WiFi Routher Setup Articles:

• - How to connect a Wi-Fi router on the example of the router Trendnet.
• - even more detailed instructions By setting up and connecting the Wi-Fi Router.
• - What to do if WiFi never earned.

Usually, for home use does not need a router with a print server (with software that allows you to share a user to share a printer by connecting it via USB). Nevertheless, if this function is necessary, do not forget about it when choosing and buying a model you like. In the next chapter, we made up a home router rating based on their characteristics, which in our opinion are the most the optimal choice By the ratio of price quality.

After the appearance of computers and laptops, in almost every house, the number of customers from providers increased several dozen times, as in modern world For many, life without internet is almost unthinkable.

For a start, an ordinary information transfer protocol through telephone communicationThen an increase in the amount of information transmitted required 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 was invented wireless way Transfer of a large amount of data for quite a long distance that Wi-Fi is named. In the modern world in many major cities you can find points access Wi-Fi And everyone can do it, in the presence of a release in 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

To the choice of the router should be approached thoroughly, since it will depend on it the features of the created wireless network. 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 cellular communication. IN this case There are no ports, 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. Everything modern laptops They 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, in the presence of a high speed connection at the router (due to the features of the service provider) this method of organization home network Not recommended. WLAN port does not have such a hard restriction.
2. If a mother card Provides the possibility of installation internal block network reception, 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 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 is also worth considering that to achieve high speed The antenna transmissions should work according to the 802.11n protocol. 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 ruler budget optionsSo 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. Installed two powerful antennas. The cost is within 4000 rubles.

In conclusion, we note what to do Wi-Fi at home Without the presence of a special router, it is possible only in the case of a device, with a built-in module that is able to distribute, and not just take the 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.

Photo - Networking with multiple conjugate devices

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 whole nearby. additional features, among which:

• 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 it is not expensive model this device. Otherwise, the router can hang, not withstanding large loads.

Some models of routers can be equipped USB ports To connect to them, the flash carrier or hard disk. 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:

• for an organization home connection or network for a small office will be enough of the usual (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.

Photo - An example of a network of users with a router

In practice, there are some other data transmission systems on the device connected to the router. For example, using the address of the sender or protocols upper levels Headers. 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 setup software Router. Equipment setting is not typical and may differ depending on the router model and connection settings from the provider. The setting can be done through any browser installed on the computer ( Google Chrome., Opera, Internet Explorer., dr.). 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 directly wi-Fi Setup Connections. If the router is equipped with a function fast settingsThe Quick Setup service needs to be launched and follow the installation wizard prompts. 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.

Photo - module wi-Fi connections Signal

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 remains only to connect network card On a PC or laptop and enjoy the operation of the device with the Internet. On the laptop you need to make sure that the special key is pressed, including wi-Fi mode. If a this operation Made, then you need to connect the device to the network.

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

Today, the electronics market and computer equipment It offers its customers a wide selection of routers distinguished 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, considering functionality The device, 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.

Hypothetically, if we saw all the digital signals that surround us, what would they like? If we could physically see the track WiFi, how would he be? This question explores the photographer and artist Louis Hernan in his newest Series Works called "Creative Study of Wireless Spectra".

Waves obsessed with invisible infrastructure that fasten our wireless world, Louis decided to capture the scenery of electromagnetic waves in a series of amazing color photographs. Snapshots quickly gained popularity that fought the author for further research in this area.

Using the camera with high exposure and RSSI sensors to visualize wiFi networksHe was able to create these bright paintings. The result is a beautiful collection of surreal images, simultaneously active and static. People often abuse technology, but not even think about their nature. But thanks to Louis Ernan you can now imagine what Wi-Fi looks at your home!


This project is designed to demonstrate the nature of the space of electromagnetic waves and to prove that high technologies can be visualized. If the human eye does not see something, it does not mean that this does not exist. And the author of these pictures was brightly demonstrated, making Wi-Fi waves temporarily accessible to perception.


The Digital Ethereal project is a progressive creative research work exploring the materiality of wireless protocols. As part of this work, these impressive photos were made.

In this lesson, I will show how to find out the password from my Waifa. Consider several ways: through windows settings, via command line, through the router menu.

The easiest way to find out the password from Waifa

Windows 10.

one . Click right-click on the icon on the taskbar and select "Open network and Internet options".

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

2. Go to the "Setting Adapter Settings" section.

3. A new window will open. Click right-click on the desired connection and select the "Status" item.

four . In the window that appears, click on the "Wireless Properties" button.

five . Go to the "Security" tab, click on the "Display Idge" item and get a password.

Windows 7.

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

Windows 10.

one . Open start and right in the print menu that appears Control Panel. Run the application.

2. Go to "Network and Common Access Control Center".

3. Click on the connection.

four . Click on the "Wireless Properties" button.

five . Open the Safety tab, click on "Display Input Enabled" and get a password.

Windows 7.

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".

Using the command line

one . Press the combination of the Win and R keys on the keyboard.

2. In the cmd type row and click OK.

3. In the window that appears, print or copy / insert the Netsh Wlan Show Profiles code and press the Enter on the keyboard.

All wireless networks saved on the computer will appear.

four . Enter the code nETSH WLAN SHOW PROFILES NAME \u003d Name of Sset Key \u003d Clear And press ENTER.

For example, if you need to find out the password from connecting "iPhone", enter such a command: Netsh Wlan Show Profiles Name \u003d iPhone Key \u003d Clear

five . You can view the password from Waifa in the "Security Settings" item in the "key content" row.

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.
