Internet access via Wi-Fi using many Russian users.Enter by connecting to the Internet, the password is often without thinking about where it came from.In many cases, setting the home network users trust the specialists invited from service centers.Of course, this is a paid service.And very often opaque (from the point of view of the user hardly understands the actions conducted master).
However, many owners of home computer networks want to learn more about the nuances of the hardware configuration and software to learn how to work with the "iron" on their own, without the involvement of third-party helpers.
Such initiatives are easy to implement.At least because the wireless configuration process usually is to specify only a few key parameters.One of them, in fact, a password.
What are the nuances to be aware of when setting up a home wireless network?What is the value of the password for the Wi-Fi?What are the characteristics settings routers?How to change your password over WiFi correct way?
We will act in accordance with a very simple instructions.It will allow us to set or change the password on a WiFi-router, as well as introduce others, that are required to install Internet connection settings in the router settings.
Why do I need a password for Wi-Fi?
If the wireless network is not protected by a password, then it can connect to absolutely anyone people with devices supporting Wi-Fi-standards.At his disposal will be free internet access, as well as the potential to gain access to files on the devices on the network.
What password is the most reliable?
specifics of wireless communication is that the security of password protection against unauthorized access to the network depends on several factors.
length and complexity
first - is the length and complexity of the password.It is necessary to obstruct the possibility of matching or guessing.Before thinking about how to change the password on WiFi, get a useful program generator random characters.On the Internet, these solutions are presented in a large amount (including in the form of on-line scripts that do not even have to download).
Encryption
The second factor - is the protection of the decryption password.The fact that the symbol combination, which introduces used to access the network, is stored in the hardware database router.If a hacker can break into it, then read and password.To do this, he may, by the analysis of radio traffic that generates router.
Privacy
third factor - reliable methods of storing passwords secret.This is an essential condition of network security.The hacker just dreaming about how to view the password for WiFi, laid out the owner of the router in a prominent place. Although the password can be very complex, ideally you need to remember it and never burn.And not to tell, of course, all in a row.There are cases when the attacker, deciding on how to find the password in the WiFi, in every way trying to find out the owner of a secret storage location of the desired code.
In order to prevent such acts IT-engineers have developed a variety of encryption algorithms Wi-Fi-connection.Consider their basic versions.
WEP-encrypted
This algorithm is the most basic, and therefore relatively fragile.But when no other choice - they have to use.WEP-defense does not let the user in the Wi-Fi-network without entering the correct password, but generated as part of the algorithm is very easy to network traffic stands simplest hacking programs that can be mastered by any novice user.
therefore calculate the password within WEP-protection is very simple.Accordingly, there will be no problems with how to change the password over WiFi, so that even the owner of the router was not able to enter the network.
WPA-encrypted
In order to improve the security of wireless networks IT-engineers have created a new encryption protocol WiFi-connection - WPA.It implemented a number of different technologies designed to minimize the likelihood of calculating the password by analyzing the radio traffic.Feature encryption technologies within the WPA-protocol that data in Wi-Fi-networks are transmitted in a large number of packets with a non-content.
While when WEP-protection data transmitted within a single stream.If a hacker intercepts a packet encrypted with the protocol WPA, it is not able to calculate the password is not to compare the data with information from hundreds or even thousands of others.For this he will need a lot of time.And therefore, if the password is complex enough, the probability of cracking WPA-encryption will be extremely small.
WPA2-encrypted
This communication protocol is the next step in the development of the previous algorithm for wireless security.It is optimized mainly in terms of speed and can effectively encrypt data for a large number of devices connected to the same network.At the same time WPA2 algorithm has an even stronger security than WPA, in the aspect of calculating a password.
Configure router
Before you put a password on a router, we will need to make a number of other settings.First of all, you need to properly connect the device to your computer.And in wired mode.
Guide, which is given below, is suitable, of course, not all routers.Procedure user on how to set or change the password on the TP-Link, WiFi-router from ZyXel, modem, released under the brand D-Link, may differ.But the difference between the approaches to the setting of different models is usually minimal.If they will, in most cases, the user can adapt these instructions to a particular brand of router.
hardware configuration of the router
Most routers have three basic types of ports (located in the rear of the chassis).Some of them (usually one) is connected to the communication channel to the Internet (DSL, Ethernet, «fiber" and t. D.), And other devices designed to connect to a PC and a power source.
the port that the device is designed to connect with a worldwide network, as a rule, signed as «Internet».Connecting the device to a PC, in most cases through the Ethernet-cable ("twisted pair") or USB-cable.Both are fairly easy to identify the specific configuration of the connector, and sometimes color.Ethernet-cable, usually, yellow, and USB - blue.
possible, should be connected "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, and the other - to the network card in your computer.A small tip for us will be the fact that the connectors are there and there are exactly the same, unlike the USB-connection.
Connecting the router to a PC to do when both devaysa de-energized.First of all, we turn on the router, make sure that the power light on the front panel lights.Then - the computer.After the operating system on the right side of the bottom panel (next to the clock and language layout) should appear indicator LAN.
This work associated with setting up the hardware, can be considered completed.We proceed to the stage of interaction with the device at the software level.
software configuration router
We need to run the router management interface.It will allow us to produce a large number of actions.With it, you can set or change the password find WiFi on your computer.
To start the interface we open any browser and type the following in the top line of IP-address: 192.168.0.1.In the window that appears, enter the username and password that sound the same: admin (in some other routers username - root).
The user will enter the interface, which will be the configuration options of the router.We are interested in tab, which contains the word Wi-Fi.By selecting it, we get to the page where you need to enter the following data:
1. The name of the wireless network (SSID).
It can be anything (in Latin letters).It is recommended to stick to neutral and easy to remember words.
2. Select the type of authentication.
remember our mini-lecture on the methods of encryption.Choosing the most reliable type of authentication, that is, one in which the title contains abbreviations WPA or WPA2.
3. own password.
Minimum length - 8 characters.What is the password to the WiFi most reliable?We have partially answered this question advised to use the program-generator of random sequences of characters.But if access to such software is not present, you can do a combination of letters and numbers.For example, one symbol - the letter, the other - a figure.
After all operations press the button "save changes" (in English «save settings»), waiting for a reboot of the router for about a minute.Done.You can disconnect the "twisted pair", connect the router to the PC.Now it will operate Wi-Fi-connection.Connect can be any device that supports wireless connection.
How to change your password over WiFi when necessary? In order to do this, you need to re-connect the router with a cable to the PC and enter into the management interface.Then we choose the now familiar tab settings Wi-Fi and get to the desired page - the one on which the password will be visible.And where it can be changed to any other.That is, there will be problems and how to find out your password to WiFi.
Nuances configure the Internet connection
In some cases, the implementation of the above operations is not enough.The fact that this scenario reflects the process of setting up Wi-Fi-connection with the password in cases where the option Internet connection installed automatically by the system in accordance with the standards adopted by the majority of the Russian providers.
It is possible that one or another operator access to the Internet is working with other settings.For example, to use the services of access to online rendered Belarusian provider ByFly, you must make a number of additional actions with the router.Which ones?
Before you configure a wireless network and set a password for WiFi-modem, you must verify the correctness of options governing Connect the router to the Internet.To do this, go to the interface device control using the IP-address 192.168.1.1., Select the option that will be called the «Internet Setup» or another in this way.
On the next page, select the correct connection protocol router to the Internet: In most cases, this is PPPoE / PPPoA.
is also necessary to set the correct values for VPI and VCI.In the city of Minsk, for example, will need to enter the digits 0 and 33.
provider can organize network access by login and password, which are also entered in the neighboring fields.For customers ByFly username will correspond to the number of the contract.Password specified in the text of the treaty.
Depending on the configuration of the modem may need to select the correct option in such areas as «Bridge Interface», or, for example, «Dynamic Route».
After entering all the required parameters can be finally set or change the password for WiFi.ByFly - definitely a modern telecommunications operator.But some steps to configure modems for use of its services to customers still need to make their own.
Even if there is a need to set the above settings or adjust them, see the options associated with a wireless connection, any changes are required.Internet connection and Wi-Fi-network from a technological point of view - two different router module.Think about how to change the password over WiFi upon adjusting the settings Internet connection is not necessary.It need only ohm if the user for some reasons decided to change a secret code to the network.
We only note that modern providers usually try to work with the settings of the modems in the default user.All these operations are generally not required to produce, but it is possible that such a need arises.
How to change the password on the WiFi, we now know.We also learned some subtleties associated with the security of wireless networks, and data encryption technologies.
