How to change the password on WiFi? How to find out the password on WiFi?

Internet access via Wi-Fi is used by many Russian users. Enter, connecting to the Internet, the password, often without thinking about where it came from. In many cases, the users of the home network are trusted by specialists invited from the service centers. This, of course, is a paid service. And very often opaque (from the point of view that the user has difficulty understanding the actions performed by the master).

At the same time, many owners of home computer networks want to learn more about the nuances of setting up hardware and software, to learn how to work with hardware independently, without involving third-party assistants.

Such initiatives are easily implemented. At least because the process of setting up wireless networks, as a rule, consists in setting just a few key parameters. One of which, in fact, is the password.

What are the basic nuances that you should pay attention to when setting up your home wireless network? What is the meaning of the password for Wi-Fi? What are the features of router configuration? How to change the password on WiFi in the correct way?

We will act according to a very simple instruction. It will allow us to set, or change the password on the WiFi-router, and also enter other parameters necessary for setting up the Internet connection, settings in the router's settings.

Why do I need a password for Wi-Fi?

If the wireless network is not protected by a password, then absolutely anyone can connect to it with a device that supports Wi-Fi standards. At his disposal will be free Internet, as well as the potential for access to files on devices that are on the network.

What is the most reliable password?

The specificity of wireless communication is that the reliability of password protection against unauthorized access to the network depends immediately on several factors.

Length and complexity

The first is the length and complexity of the password. It is necessary to complicate the possibility of its selection or guessing as much as possible. Before thinking about how to change the password on WiFi, it's useful to get a random generator program for random character sets. On the Internet, such solutions are presented in large numbers (including in the form of online scripts, which even do not need to be downloaded).

Encryption

The second factor is the protection of the password from decryption. The fact is that the combination of characters that you enter to use for accessing the network is stored in the router's hardware database. If the hacker can penetrate it, then he will read the password. To do this, he can through the analysis of the radio spectrum that the router generates.

Secrecy

The third factor is the reliability of the methods of storing the password in secret. This is an essential condition for network security. The hacker only dreams about how to see the password on the WiFi, laid out by the owner of the router in a prominent place. Despite the fact that the password can be very difficult, ideally you need to remember it and do not write it anywhere. And do not tell, of course, all in a row. It is not uncommon for a hacker, when deciding how to find out the password on WiFi, tries in every possible way to find out from the owner the secret place of storage of the necessary code.

In order to suppress such actions, IT-engineers developed various algorithms for encryption of Wi-Fi communications. Consider their main varieties.

WEP Encryption

This algorithm is considered the most basic, and therefore relatively unreliable. But when there are no other options, you will have to use it. WEP-protection will not allow the user to enter the Wi-Fi network without entering the correct password, but the network traffic generated within the framework of this algorithm is very easily deciphered by the simplest hacker programs that any novice user can master.

Therefore, it is very easy to calculate the password in the framework of WEP-protection. Accordingly, there will be no problem with how to change the password on the WiFi so that even the owner of the router can not enter the network.

WPA encryption

In order to increase the level of security of wireless networks, IT engineers have created a new WiFi encryption protocol - WPA. It implements several different technologies at once, designed to minimize the probability of calculating the password through analysis of radio traffic. The peculiarity of encryption technologies in the framework of the WPA-protocol is that the data in the Wi-Fi network is transmitted within a large number of packets with inconsistent content.

While WEP-protected data is transmitted within a single stream. If a hacker intercepts one packet encrypted using the WPA protocol, it will not be able to calculate the password until it compares data with information from hundreds or even thousands of others. He will need a lot of time for this. And because if the password is complicated enough, then the probability of hacking WPA encryption will be extremely low.

WPA2 encryption

This communication protocol represents the next step in the development of the previous wireless network security algorithm. It is optimized mainly in terms of speed and allows you to effectively encrypt data for a large number of devices connected to the same network. At the same time, the WPA2 algorithm has even stronger security than WPA, in terms of calculating the password.

Configuring the router

Before putting the password on the router, we will need to make a number of other settings. First of all, you need to connect the device to the computer correctly. And in a wired mode.

The instruction that follows is certainly not suitable for all routers. The user's procedure regarding how to set or change the password on the TP-Link, the WiFi router from ZyXel, the modem, issued under the D-Link brand, may differ. But the difference between approaches to tuning different models, as a rule, is minimal. If they do, in most cases the user will be able to adapt this instruction to a specific router brand.

Hardware configuration of the router

Most routers have three main types of ports (located at the back of the chassis). Some of them (usually one) are connected to the Internet connection channel (DSL, Ethernet, "fiber", etc.), others are designed to connect the device to a PC and a power source.

The port that is designed to connect the device to the worldwide network, as a rule, is signed as "Internet". The device is connected to a PC in most cases via an Ethernet cable ("twisted pair") or a USB wire. Both are easy to recognize by the specific configuration of the connector, and sometimes by color. The Ethernet cable is usually yellow, and the USB cable is blue.

If possible, you should connect a "twisted pair" (in this case we do not need to install drivers for the device). One end of the cable, which is likely to be yellow, we connect to the router, the other - to the network card of the computer. A small clue to us will be the fact that the connectors are both the same and there and there, unlike the USB connection.

Connecting the router to the PC should be done when both devices are de-energized. First we turn on the router, make sure that the power light on the front panel lights up. Then the computer. After loading the operating system on the right side of the bottom panel (next to the clock and the language layout), you should see the indicator for connecting to the local network.

On this work, connected with the adjustment of the hardware, can be considered complete. Let's move on to the stage of interaction with the device at the program level.

Software configuration of the router

We need to start the management interface of the router. He will allow us to produce a large number of actions. With it, you can install, change or find out the WiFi password on the computer.

To start the interface, we open any browser and enter the following IP address in the top line: 192.168.0.1. In the window that appears, enter the login and password, which sound the same: admin (in some routers the user name is different - root).

After that, the user will go to the interface page, in which there will be options for configuring the router. We are interested in a bookmark that contains the word Wi-Fi. Selecting it, we get to the page, where you will need to enter the following data:

1. The name of the wireless network (SSID).

It can be any (Latin letters). It is recommended to follow neutral and easily remembered words.

2. Select the type of authentication.

We recall our mini-lecture on encryption methods. We choose the most reliable type of authentication, that is, one whose name contains abbreviations WPA or WPA2.

3. The password itself.

Its minimum length is 8 characters. What is the password for WiFi the most reliable? Above we partly answered this question, advising us to use the program generators of a random sequence of symbols. But if you do not have access to such software, then you can do with a combination of letters and numbers. For example, one character is a letter, another is a digit.

After all operations click on the button "save changes" (in English "save settings"), wait for the reboot of the router for about a minute. Done. You can disconnect the "twisted pair" that connects the router to the PC. Now will work Wi-Fi-connection. You can connect from any device that supports wireless connection.

How to change the password on WiFi if necessary? In order to do this, you need to reconnect the router with a cable to the PC and enter the management interface. Then we select the now familiar bookmark with the Wi-Fi settings and get to the right page - the one on which the password will be visible. And where it can be changed to any other. That is, there will be no problems with how to find out the password on WiFi.

Nuances of setting up an Internet connection

In a number of cases, the above operations are not enough. The fact is that this scenario reflects the process of setting up a Wi-Fi connection with a password in cases when the Internet connection options are set automatically by the system, in accordance with the standards adopted by the majority of Russian providers.

It is possible that this or that operator of access to the Internet works with other settings. For example, to use the services of online access provided by the ByFly Belarusian provider, it is necessary to perform a number of additional actions with the router. Which ones?

Before setting up a wireless network and setting a password on the WiFi modem, you need to make sure the options that govern the connection of the router to the Internet are correct. For this, by entering the device management interface using the IP address 192.168.1.1., You must select an option that will be called "Internet Setup" or the like.

On the opened page it is necessary to choose the correct protocol of connection of the router with the Internet: in most cases it is PPPoE / PPPoA.

It is also necessary to set the correct values for VPI and VCI. In the city of Minsk, for example, you will need to enter the numbers 0 and 33.

A provider can organize access to the network by login and password, which are also entered in adjacent fields. For ByFly customers, the user name will match the contract number. The password is specified in the text of the contract.

Depending on the configuration of the modem, you may need to select the correct options at such points as "Bridge Interface", or, for example, "Dynamic Route".

After entering all the necessary parameters, you can finally set or change the password on the WiFi. ByFly is definitely a modern communication operator. But some actions to configure modems to use its services customers still have to do it yourself.

If there is even a need to set the above settings or correct them, in the options section related to the wireless connection, no changes are required. Internet channel and Wi-Fi network from a technological point of view - two different router modules. You do not need to think about how to change the password for WiFi after adjusting the settings of the Internet connection. It will be required only in case, if the user himself for some reason decided to change his secret code to enter the network.

Let's note only that modern providers, as a rule, try to work with the settings set in the default modems of users. All the above operations are generally not required, but it is possible that such a need will arise.

How to change the password on WiFi, we now know. We also learned some of the subtleties associated with wireless security and data encryption technologies.
