How to connect to Wi-Fi without knowing the password. What is an Internet connection via Wi-Fi? Does the Internet work via Wi-Fi?

Turn on the search for Wi-Fi networks on your gadgets, laptops and computers - and you will see how popular wireless access technologies are, and how densely they have penetrated into apartments and offices. The range of some routers is sometimes amazing: when searching for networks, you can easily find a network even, for example, on the other side of the street and connect to it. And dual-band routers allow you to avoid collisions and free up the airwaves by using a higher frequency.

As a rule, laptops, smartphones, TVs and gaming gadgets require an Internet connection. The operating systems Windows, Android and iOS have fundamental differences in connection method. Let's look at them in order

Connect your laptop and computer to your router via Wi-Fi

To connect to wifi, you need, at a minimum, to know the password (the data encryption key in the case of cryptoprotection of the network and traffic). Let's consider connecting a laptop or desktop computer to an already configured and functioning router remotely.

Our goal is to connect to the Internet and to the local network.

We check that:

The router is connected correctly to the provider and distributes the Internet.
The Wi-Fi adapter is installed, functioning correctly, the drivers are installed and up to date.

Connection via WPS

The simplest way to connect to a router, which does not require knowledge, is through WPS. It can be hardware (using a hardware button) or software (using a pin code).

The button is pressed once and not for long (a second press is enough) both on the router and on the WI FI adapter.

After one or two minutes, the router and adapter themselves “agree” with each other on the addresses and encryption password, and the Internet becomes available on the device.

Sometimes a device may not have a WPS button, but still support it. In this case, the WPS PIN is indicated on the label: when setting up a wireless network, the OS will ask you to enter it.

Despite the apparent simplicity of connection, it is deceptive: when activating a connection to Wi-Fi using WPS, three procedures are involved:

generating a key (password);
encryption of the generated password
imposing additional encryption on the channel using a certificate.

Due to the lack of complete transparency of this procedure - you do not know the password and connection parameters - it is recommended to use the standard connection option with entering a key.

If the router was not initially configured, then by entering the WPS PIN, you can configure all network parameters as desired: its name and key.

Standard option for connecting laptops and computers to the router

Let's look at how to connect to the wireless Internet through a pre-configured router.

All modern laptops are equipped with a Wi-Fi module. But a desktop computer should be equipped with a Wi-Fi adapter.

Please note:

(1): All available wifi networks are visible here. Select our network (2), click (3) Connection to connect to the modem and, accordingly, the Internet.

A window appears asking you to enter a password (security key); and if the key is entered correctly, a successful Internet connection icon will appear:

Your computer can successfully use the resources of your local home network and Internet access through your router.

Connecting smartphones and gadgets to the router

For smartphones and mobile gadgets, connecting to the Internet through a router is an opportunity to save on traffic and, accordingly, money when paying for operator services. The 4G network requires more resources and battery power than wireless access, so the smartphone will “live” longer with the Internet from a router without a GSM service provider. Any smartphone equipped with a Wi-Fi module can connect to your router's Wi-Fi.

Let's look at how to connect when the Internet is configured and distributed by an access point.

Android OS

We will demonstrate step by step how to connect the Internet through a router using the example of a smartphone with Android OS.

In the settings of your smartphone, turn on the Wi-Fi module, available networks will be automatically scanned.
Select your network from the list.
Enter the network key (which was entered at the router setup stage).
If the connection is successful, the corresponding “Connected” signature will appear.

If you can't connect to your network device, restart both it and your smartphone. Check the settings of your Internet distribution device and try connecting to the wireless network again as described above.

iOS OS

Let's take a step-by-step look at how to connect gadgets running the iOS operating system to the router.

In “Settings” you should select the “Basic” section, where you can check whether the wireless module is turned on: when you move the slider to “ON,” an automatic search for available networks is performed. Select your network and enter the password (network key).

If the key is correct, the iPad and iPhone will successfully connect to the Internet.

Connecting to an unknown network device

We discussed above how to connect to a home access point, the parameters of which are known. However, there are situations that require connecting to someone else’s equipment remotely, without information about the key and connection parameters.

Let's look at how to connect via Wi-Fi to the router in this case.

Password selection

Users of home networks, due to inexperience, little knowledge and laziness, rarely create complex keys. Therefore, the question of how to connect to a wireless network is easy to solve: there are a number of programs for selecting a key using a dictionary. For example, WiFICrack.

This program also solves the problem of how to connect to a hidden network that does not send broadcast packets. All you have to do is scan the airwaves, check the boxes of those networks you are interested in connecting to, download the dictionary (you can use the built-in one) and start selecting.

As a result, a Good.txt file will be created containing the names of the networks and their keys that were found.

Password interception and cracking

Programs for capturing and decrypting wireless network packets are also available via the Internet. The essence of the method: even in the absence of correct authentication, the network device exchanges packets that contain the key in encrypted form with the connected gadget. Isolating such packets and decrypting them is the path to revealing the key.

This is a class of programs for experienced users with knowledge in the field of computer security.

One example of this class of programs is Airslax.

Works with WPA/WPA2 traffic decryption and WEP encryption. The numbers indicate:

Scanning the airwaves, finding all networks, their signal levels, encryption options and other features.
Selecting the decryption target. The networks in the list are ranked in ascending order of their signal strength.
The process of intercepting the selected network.
Disconnecting the client from the point to initiate a repeated authentication process: the first 4 packets contain the key in encrypted form.
Guessing the password for a captured headshake encrypted with WPA/WPA2 using a dictionary.
Saving results.
Automatic key guessing for WEP encryption: a large number of DATA packets are collected, and authentication is attempted every 5000 DATA packets collected.
Here points with the possibility of authorization via WPS are scanned.
Using Reaver or Bully, a pin code is selected.
Automatic operating mode.

Security of your own network equipment

Having briefly examined the main methods of standard and unauthorized connection, let us recall the basic basic requirements for your own equipment.

Change default usernames and passwords on the router. Many people neglect or forget to perform this simple procedure, leaving a loophole for attackers.
Enable encryption that is as difficult to decrypt as possible - WPA2. It will significantly complicate and increase the time of hacking; attackers will prefer a simpler network to connect to.
Restrict access by mac address. Although replacing the address of a network card is not difficult, limiting the MAC address is a necessary procedure for protecting the internal security loop.
Change your Wi-Fi access key at least once every six months. Even if attackers do connect to your network equipment, regularly connecting and repeating the hacking procedure will force them to find a more accessible victim. This will not protect you from unauthorized connections, but will significantly reduce the likelihood of hacking. Safe and fast connections for you!

The Internet has become such an integral part of the lives of most that we no longer notice it - as if it had always been there and people did the same things as easily all the time as they do today. However, this is not true and connecting to the network even today requires certain equipment, passwords, payments and tariff plans.

Finding ourselves in an unfamiliar place, we often need urgent access to the network, but how to connect to WiFi without knowing the password? It remains a mystery to many, but connecting to Wi-Fi without a password is possible!

Methods for connecting to a wifi network

There are several ways to connect to Wi-Fi without a password. The most important ones are brute-force attacks, phishing, and key interception.
First of all, try to choose the right combination. At first glance it may seem that this is impossible, but it is not. Often, in order not to forget, people make it as simple as possible. For example, 12345678 or something like that. Imagine yourself in the shoes of someone who sets a simple password to connect to Wi-Fi.

If you couldn’t find the wifi key and you don’t connect, try installing the WifiCrack program. They do not charge money for downloading and using it, but you must remember that this operation is illegal and you do this only in exceptional cases and after making sure that the owner of the Wi-Fi network to which you are planning to connect is not a bank, police or other special structures.

So, now we will find out how to connect Wi-Fi without a password:

How to connect to Wi-Fi without a password if this method did not work? Connecting to someone else's wifi can be a difficult task and may require traffic interception. The optimal program that can cope with this task is Airslax. It works according to the following principle: when you try to connect to someone else’s network from your phone or from your personal computer, your device still communicates with the router on that side. Packets are being transferred without you even noticing it. And these same data packets contain an encrypted access code. It turns out that if you decrypt these packets, you can get the password. To carry out interception, you need more than average knowledge, but there is nothing overly complicated in this program.

So, let's see how to connect to Wi-Fi without knowing the password using the interception method:

Therefore, we will use the Wifiphisher program to carry out this attack.

After installing the program, the first thing to do is turn off their wireless point. How to do this is at your discretion, but don’t go overboard.
Then the wifi router will switch to the “Access Point” mode and the program will be able to copy the Name and title of the Access Point.
The DHCP server will automatically configure itself to this access point and provide our client with a fake page disguised as anything.
The client will be taken to this page and will likely enter their access point name and password.
The program will give you an access code and you can connect.

Once again, we want to repeat that no one will be able to identify you or punish you in any way for any of the above actions, but, if possible, it is always better to ask the owner of the wifi network for the password.

When you turn on your smartphone, each resident of an apartment building can see many wifi connection points. Particularly inquisitive people have a desire to use someone else’s network, but how to find out the password for Wi-Fi.

Each router has its own IP address, through which you can view all the data of the neighboring device.

WiFi is an IEE802.11 standard network. The transmitter is installed in almost every apartment. You can find out the name and address of the router from the network mask, which people often forget to change during the initial installation of the device. You can connect to Wi-Fi if the owner of the network broadcasts it without a password at all.

You can find out the type of wifi device by the name of the network displayed in the list of available ones. You can use the network unlimitedly if the device itself was able to connect without a password.

Your actions are invisible when the traffic load is low. You can detect something is wrong if your neighbor looks at the list of connected devices. And he will do this through the laptop browser, where the corresponding router address is entered.

You can go into the router settings through a browser by entering the address 192.168.1.1. By default, the nickname is set to admin and the same password.

But before that, the laptop needs to be connected to wifi. By quietly correcting the data, you can annoy your neighbor and interrupt the connection. After that, it will reset the settings to factory settings and change the access codes.

The wifi password and ip address are easy to find out using special hacking programs, but the latest versions of routers provide this feature and block automatic connections.

It is convenient to have a neighbor connection point for the following purposes:

No need to pay a monthly subscription fee;
WiFi allows you to use several devices at once, unless your neighbor sets a limit on the number of connected devices;
Your identity will not be established for illegal connections.

Hacking someone else's wifi is an illegal act, which results in criminal liability.

Whether or not to hack someone else’s router is up to everyone personally, but why not try? The IP address of the device is indicated on the back cover of the wifi transmitter. It can be viewed at a computer hardware store.

Ways to solve connection problems

To connect to most wifi networks you will have to crack the password. A simple way to solve Internet access is to purchase your own router and get your own IP address for the devices.

But an inquisitive mind is always drawn to complex tasks. The first step is to find information about the new network and whether there is a Wi-Fi password on the router.

You can find out after viewing the details of the current wifi. Open the “Control Panel” and find the Internet network item and go to the “Network Control Center”. We need to open the “Network Connection” item.

At this point you can see:

Complete list of available wireless networks;
Broadcast signal level;
Access to Wi-Fi. If it is open, then you are very lucky, use free wifi.

You can hack wifi using programs to find a suitable password. They run on your laptop and try possible variations until a connection is made.

It should be remembered that no amateur hacker can use the neighbor’s Wi-Fi completely unnoticed. The IP address is calculated instantly if you connect the device to the network.

A list of all current connections is displayed in the router itself. It is always available on a PC connected to it locally via a wire. But rarely does anyone control their network while the transmitter is operating stable. One extra neighbor on the “wire” will not make a difference; the speed drops significantly with a huge list of wi-fi “freeloaders”.

What hacking programs are there?

Applications do not guarantee 100% wi-fi hacking results; you will have to connect using several programs. Finding out the password is possible with a probability of up to 90%.

Here is a list of programs available on the Internet:

WifiSidejacking - the program interface is entirely in English, but a detailed manual helps you connect to Wi-Fi in a few minutes;
Aircrack-ng is a set of tools for competently searching for not only wifi passwords, but also helps determine the IP address of connected subscribers;
AirSlax - works with wifi in 6 simple steps: scanning the network, selecting a target, capturing packets, disconnecting the client, guessing the password and saving the finished result;
Wifipirate 13 is a powerful application that provides passwords of all surrounding wireless broadcast points;
CommViewforwifi - used to analyze networks, search for new connection points and neighbor activity time.

Aircrack-ng includes a software package of applications for decrypting intercepted files, creating encrypted signals, recovering Wep keys in Windows. It includes a tool for converting files with the ivs extension.

There is also the ability to monitor the current connection and determine the wi-fi network traffic.

Through a remote IP address, the Airserv-ng application provides access to the laptop's wireless card. Allows you to solve problems with drivers and make changes to the operating system. The program hacks wi-fi networks: Wep, searches for WPA-PSK keys, WPA/WPA2. All operations are carried out automatically without the participation of the owner of the magic code.

No programmer can predict the password selection time; it all depends on the following factors:

Password complexity, presence of letters and numbers;
Wi-fi device type;
Has the IP address changed?
Distance from the transmitter, device load.
The selected utility and scanning method.

How to hack a hotspot on Android?

Finding a password for a smartphone’s wi-fi transmitter is even more interesting. Often neighbors use the Internet through their cellular operator. Based on the results of the selected password, it is possible to determine the IP address of the subscribers.

There are software applications for scanning networks:

Wifi Password break;
To control wifi use the Wifikill program;
Wibr+ - serves as an assistant for hacking wi fi without any special hacking skills;
WiHackmobile is a simple program for finding passwords of surrounding networks;
Wi-Lomster is a popular application for working on a smartphone;
WifiRouterkeygen - quickly finds Wi-Fi passwords to connect to a neighbor. The interface is easy to use and does not require familiarization with the utility.

The listed utilities can identify the most attractive network for hacking.

You won’t be able to connect quickly if your neighbor has taken care of wi-fi protection:

Saved a long and complex password;
Changed default logins;
Purchased the latest version of the provider's router;
Turns off the transmitter when not in use;
Controls connections and has introduced restrictions on the number of devices;

There is no chance of hacking networks with a reliable level of encryption using any utility.

If the router turns off during scanning, the procedure will have to start over.

Connecting your device is half the battle, but you need to carefully hide your IP from your neighbor. When he realizes that his wi-fi network has become public, he will wonder who used the router. The problem will develop into a scandal if he comes to you.

The Wifikill utility helps you find intruders using your router. With one click, it will block a user by IP address. But he can change it, so it’s better to set restrictions on the number of connected devices. It’s better to create a list of allowed devices.

I was always a little surprised by questions like this, in which they wrote that when connected to an open (unprotected) Wi-Fi network, the Internet does not work. Or a phone, laptop, tablet and other devices generally refuse to connect to open Wi-Fi. They asked for some advice on what could be done to solve this problem.

And today, I saw a message on our forum that says that the phone catches an unprotected Wi-Fi, connects to it without problems, but the Internet does not work. Then I analyzed the comments on the site a little, and realized that the question was very popular, and I had not yet written an article on this issue. I will correct the situation now :)

Now, we will figure out why problems arise with connecting to other people’s, albeit open, wireless networks. We will try to find out if something can be done about this, and if so, what.

I would like to write right away that we will look at problems specifically with the connection and operation of the Internet connection, through other people’s wireless networks that are not password protected and with which a connection can be established.

All the problems that arise when connecting to your own networks are a different story. There will simply be more ways to solve this or that error, since you have access to the settings of the router itself.

No matter how sad it may sound, but if your smartphone, tablet, laptop, etc., does not want to connect to open Wi-Fi, or the Internet does not work after connecting, then most likely there is no way to correct this situation. it will work out. In about 90% of cases, you will have to deal with it. I wrote it somehow sadly :)

Why? Yes, because we don’t know what kind of access point there is, whose it is, how it’s configured, and most importantly, we don’t have access to the settings of this router, because it’s not ours, but a neighbor’s, some store, cafe, etc. etc. I think this is clear and logical.

Here, let’s take for example the question I wrote about at the beginning of the article:

It was posted on our forum, in this topic: .

It’s a good question, but do you think it’s possible to give something substantive to this question? I also think not. Maybe the Internet is simply not paid for there. There is a connection, but the Internet does not work. Standard situation. Maybe there is some kind of blocking enabled, or the phone didn’t like the channel on which it works.

I would highlight two main problems. We will divide the article into them. It will be easier and clearer this way.

Can't connect to an open Wi-Fi network

This is probably the most popular question. On laptops (and desktop computers), it could be an error " ", or something else.

On mobile devices (phones, tablets), it could be...” (by the way, laptops can also have this “Identification...” problem), " ". There may be other errors.

If you can’t connect, then you need to think about why this network is not protected. Yes, there are people who simply forget to do this, or they don’t need it. They just let everyone use their internet. (this is the case with home access points). But, I am sure that in most cases, there is no password because filtering by MAC addresses is enabled (read). Which protects even better than a password.

What can you try to do?

Typically, when connecting to unsecured networks, the signal strength is not very good. Make sure that the network level is at least two divisions high. Otherwise, connection problems may arise precisely because of a weak signal.

If you are connecting a laptop (regular computer with adapter), then make sure that in the properties of the wireless adapter, in the IPv4 protocol, it is set to receive IP automatically. Like this:

I showed the example of Windows 7. In Windows 8, everything will be exactly the same.

If the problem occurs on mobile devices that run on Android OS or iOS (iPhone, iPad), then I don’t even know what to advise. Except how to monitor the signal level. There don't seem to be any special settings that would interfere with the connection.

Internet does not work when connected to unsecured Wi-Fi

Well, the second problem is when everything is connected, but the Internet does not work.

On a laptop, there will be a status “No Internet access” and a yellow triangle next to the network status (in), but on mobile devices the Internet simply will not work, and the Wi-Fi icon will most likely be gray instead of blue (depends on OS, firmware version, etc.).

How to fix the problem?

If the problem is on the computer, then check the IP settings, as I showed in the screenshot above. Disable antiviruses and firewalls, they may block access to the Internet.

If the problem is on a mobile device, then check whether manual proxy settings are enabled. How to do this, I wrote in the article (after the heading “checking if the proxy server is disabled”).

In other cases, the problem is most likely on the side of the router itself. Or, your device cannot work with the parameters specified in the router settings.

Afterword

As I wrote above, if the phone does not connect to the network, then you are unlikely to be able to do anything. If it connects, but there is no Internet access, then the same thing. The network is not ours, we don’t know what’s wrong with it, we can’t change the settings. Almost all problems that arise with Wi-Fi are to blame for the access points themselves. And, if you try to fix something, then you need to change the settings in them. Provided that your device works normally with other networks.

Hi all! After reading the article below, you will learn how to connect a laptop to the Internet via wifi. A laptop is considered a mobile computing device. By purchasing it, the user gets the opportunity to use it absolutely anywhere. It is not very favorable to connect a laptop to the global network via a cable. Having thus connected to the Internet, the laptop turns into a simple home PC. That is why I decided to take on this topic, since it is currently very relevant.

The first thing you need to do is find the “wifi” icon. This sign may look different for everyone, it will depend on whether the laptop is connected to Wi-Fi or not connected.

This icon serves as an assistant for various operations.
So, after this, a window will appear in which all available network points will be displayed. Select the required network and click "Connect".

Then there are 2 options. If the network is not password protected, the connection will occur immediately. If the network is password protected, a window will appear where you will need to fill out a line.

After entering the password data, the Internet should work.

If you have any problems, then read on.

I can't find the icon I need

If you have a problem such as the absence of the “wifi” icon on the taskbar, then your Wi-Fi module is disabled. To enable it you must do the following:

Log in to the “Control Panel”;
Go to “Network and Internet”;
Then visit the Network and Sharing Center;
Select "Change adapter settings";
Find “Wireless network connection” and connect it through the context menu.

Sometimes a similar issue arises due to the lack of drivers. In this case, they will simply need to be installed.

The icon is marked with a red cross

This is another common problem. In this case, the user will not be able to connect.

Usually, this means that such a module is disabled through the “Mobility Center” or through certain buttons on the body of the laptop itself.

To solve the problem you need:

select the battery icon with the right mouse button;
select “Windows Mobility Center”;

Specify “Enable wireless communication.

If such a network is already turned on at this point, it means that the module is turned off through buttons or key combinations.

Conclusion

Thus, now you know how to connect a laptop to the Internet via wifi. I hope that my information will be useful to you. Thank you for your attention, good luck everyone!
