How to disconnect devices from wifi. Turn off Wi-Fi on the router

When purchasing a device for accessing the Internet, people want it to be used only by themselves or their authorized representatives. But someone else can always freely connect to your network if it is not secure enough. What to do in such cases and how to disconnect the user from WiFi router? Below is detailed information about it.

Viewing the connection of foreign devices

It is necessary to think about the fact that you have got a thief who secretly uses wireless resources from you when:

1. The connection indicator on the router is constantly on (provided that you do not use the Internet yourself).
2. Data exchange is extremely slow, although your equipment is not exerting load (for example, there are no file downloads and other activities that could negatively affect the speed of the Internet).

If you have the above, you should check if there is a connection of foreign users to your network. To do this, do the following:

1. Check connection quality.
2. Specify the username and password to enter the router settings.
3. Find the section that displays devices that are currently connected to yours and are using the network without permission.

In order not to get confused, you need to know the names. Most often, they are registered by the factory or unique name that you yourself set them. If you don’t know the names, then before entering the desired section, you can turn off all your devices, then they will not be displayed (after turning them off, it is recommended to wait 15 seconds so that the router has time to update information about turning off the equipment). This will allow you to detect other people's connections.

An additional way to view third-party users is to use special program. For example, Wireless Network Watcher.

Work in it is simpler and more visual, may be suitable for inexperienced users. Such a program will quickly perform a scan and give a detailed result about freeloaders that you did not know about.

A separate advantage of the program is that it displays which devices are yours and which are strangers.

For video instructions on how to detect, disable, and block third-party users from your Wi-Fi network, see the following video:

Disabling and blocking someone else's user

How to block a Wi-Fi user so they can no longer connect to your personal router? If a third-party user is detected who exploits your resources secretly from you, then to disable and block him, you must perform the following steps (the above steps can be performed both from a computer and from a phone):

1. Check the functionality of the router and connect.
2. Enter the address of the router into the browser.
3. Specify the login and password to enter the settings (usually at the bottom of the router).

1. Find the section that displays the devices that are currently connected to you. Depending on the router model (ASUS, TP-Link, Rostelecom, etc.), the names of such sections may differ.

1. Copy the MAC address of the device of interest.
2. Select someone else's device and click on the button to disconnect it from the Internet (if necessary, you can disconnect all at once. To do this, check the boxes next to each device and click on the corresponding button).
3. Go to the section responsible for MAC address filtering.
4. Copy the MAC address of the device that was disabled there. After that, the device will be blocked and when trying to connect to your router, it will not be able to succeed.

In addition to the above method, you can disable router freeloaders using a special program (for example, SoftPerfect WIFI Guard, Netcut or other similar programs).

Such a program will perform a full scan, identify other people's devices, and prompt you to disconnect them from you.

The minus of the program: it turns off someone else's device, but does not perform full blocking (it can only be installed on the router). If there is no blocking, the user may reconnect to your network after a while.

ASUS

To disable users in this model, you need to:

1. Log in to ASUS.
2. Click on the "Clients" button, after which information about other users will be displayed.

1. To block: go to the address filtering tab, specify the necessary ones, after which access for them will be denied.

TP Link

To disable and block "left" clients, do the following:

1. Log in to TP-Link.
2. Select item " Wireless mode” and go to the statistics section, where you can see the MAC addresses of other users.
3. To block: go to the MAC address filtering section and set connection blocking for a specific address.

Rostelecom

To disable foreign users in this model, you need:

1. Log in to the router.
2. To view connected devices, go to the "List of Wi-Fi Clients" tab (for more details, technical information you need to go to the DHCP tab).
3. To disconnect unwanted clients in the list, select the necessary client and click the disconnect button.
4. To block: copy the MAC address, go to the section for filtering such addresses and add a dedicated one. After that, the device will not be able to connect.

How to increase the degree of security?

Other devices can connect to your network when there is a low level of protection. Here are 3 simple rules that will allow you to increase your security level:

1. Be sure to set a good password and fulfill a number of requirements for a good password:
   • at least 8 characters;
   • contains latin letters and numbers;
   • includes characters of different case, as well as special characters;
   • does not match your personal data (they are easy to pick up);
   • The password is changed every 1-3 months.
2. Do not disclose your password to third parties.
3. Turn off the router when you do not need to use the network.

How to secure your Wi-Fi networkFi, find out in the following video:

Well, useful material? And which of our readers has come across the fact that a neighbor has joined the Wi-Fi? What did you do? Share your experience, ask questions! Always happy to chat! Thanks for choosing us!

I'll tell you a story that is still going on with one Internet provider in my city. One day, I went to a friend's house and asked him for Wi-Fi access. The network is saved in the smartphone. While in another area of ​​the city, I suddenly found that I was connected to the friend's wifi. How is this possible? It turns out that the Internet provider set the same network name and password for all routers that were issued to subscribers upon connection. More than one year has passed, and I still have free Wi-Fi in almost every yard. The login and password for accessing the routers, by the way, are also the same. :)

Naturally, I told my friend about the funny discovery and reconfigured his router. Are you sure you are not in a similar situation?

Why unauthorized access to your Wi-Fi and router is dangerous

Imagine that an attacker connected to your Wi-Fi, downloaded several gigabytes of child pornography and posted a couple of hundred extremist and other "incendiary" messages. The contract for the provision of Internet services is drawn up for you, and you will also be asked for violation of the law, respectively.

Even if the connected person does not commit illegal actions, he can download and distribute for days large files(including illegal content from torrent trackers), which will affect the speed and stability of your Internet connection. The web is full of stories about free neighborhood Wi-Fi. Perhaps you, too, are that good neighbor?

The situation when an outsider knows the login and password to the router itself includes all the risks listed above, and also adds a few new ones.

For example, a joker simply changes the Wi-Fi password and you lose access to the Internet. He can change the password to the router, and you will have to perform a factory reset and reconfigure everything (or call a specialist if you do not have the appropriate skills) to regain control of your equipment. The joker himself can also reset the settings.

There is no absolute protection, but you do not need it

There are many ways to hack networks. The probability of hacking is directly proportional to the motivation and professionalism of the hacker. If you have not made enemies and do not have some super-valuable information, then it is unlikely that you will be purposefully and diligently hacked.

In order not to provoke casual passers-by and neighbors eager for freebies, it is enough to close elementary security holes. Having met the slightest resistance on the way to your router or Wi-Fi, such a person will abandon his plan or choose a less secure victim.

We bring to your attention the minimum sufficient set of actions with a Wi-Fi router, which will allow you not to become the object of evil jokes or someone's free access point.

1. Access your Wi-Fi router

The first step is to take control of your own router. You must know:

• router IP address,
• login and password to access the router settings.

To find out the IP address of the router, turn the device over and look at the sticker on the bottom. There, among other information, the IP will be indicated. This is usually either 192.168.1.1 or 192.168.0.1.

Also, the address of the router is indicated in the user manual. If the box with the instructions from the router has not been preserved, then Google will help you find the user manual in electronic form.

You can independently find out the address of the router from the computer.

1. On Windows, press the combination Windows keys+R.
2. In the window that appears, type cmd and press Enter.
3. In the window that appears, type ipconfig and press Enter.
4. Find the line "Main Gateway". This is the address of your router.

Enter the received IP address of the router in the browser. You will see the login page for the router settings.

Here you need to enter your username and password, which you must know. In most cases, the default login is the word admin, and the password is either an empty field or also admin (the default login and password are also indicated at the bottom of the router). If the router came from an Internet provider, then call him and find out.

Without the ability to change settings, you effectively lose control over your own hardware. Even if you have to reset the router settings and reconfigure everything, it's worth it. To avoid problems with access to the router in the future, write down your username and password and store them in a safe place without access to outsiders.

2. Create a strong password to access your router

Having gained access to the router, the first step is to change the password. Router interfaces vary by manufacturer, specific model and firmware version. In this case, as well as when performing subsequent steps to improve security, the user manual for your router will help you.

3. Come up with a unique name (SSID) for the Wi-Fi network

If your neighbors don't understand technology at all, a network name like fsbwifi or virus.exe might scare them away. In fact, a unique name will help you better navigate among other access points and uniquely identify your network.

4. Create a Strong Wi-Fi Password

By creating an access point without a password, you will actually make it public. Strong password will not allow strangers to connect to your wireless network.

5. Make your Wi-Fi network invisible

You will reduce the likelihood of an attack on your network if it cannot be detected without special software. Hiding the access point name improves security.

6. Turn on encryption

Modern routers support various methods encryption of data transmitted over a wireless network, including WEP, WPA and WPA2. WEP is inferior to others in terms of reliability, but it is supported by older hardware. WPA2 is optimal in terms of reliability.

7. Disable WPS

WPS was created as a simplified way to create wireless networks, but in reality it turned out to be extremely unstable to hacking. Disable WPS in your router settings.

8. Turn on MAC address filtering

Router settings allow you to filter access to the network by unique identifiers called MAC addresses. Every device that has network card or network interface, has its own MAC address.

You can create a list of MAC addresses of trusted devices, or block devices with specific MAC addresses from connecting.

If desired, an attacker can forge the MAC address of the device from which he is trying to connect to your network, but for an ordinary household wireless hotspot such a scenario is highly unlikely.

9. Reduce Wi-Fi Range

Routers allow you to change the signal strength, thus increasing and decreasing the range of the wireless network. Obviously, you only use Wi-Fi inside your apartment or office. By lowering the transmission power to a value where the network signal is reliably received only within the premises, on the one hand, you will make your network less visible to others, and on the other hand, reduce the amount of interference for neighboring Wi-Fi.

10. Update the firmware of the router

There are no perfect technologies. Craftsmen find new vulnerabilities, manufacturers close them and release "patches" for existing devices. By periodically updating your router firmware, you reduce the chance that an attacker will take advantage of flaws in older versions of software to bypass security and gain access to your router and network.

11. Block remote access to the router

Even if you protect your wireless network and login with passwords, attackers will still be able to access the router via the Internet. To protect the device from such outside interference, find the function in the settings remote access and turn it off.

12. Firewall

Some routers have a built-in firewall - a means of protecting against various network attacks. Look in your router's security settings for a feature with a name like Firewall, "Firewall" or " Firewall” and turn it on if it is present. If you see additional firewall settings, read the official instructions on how to configure them.

13 VPN

They create something like an encrypted tunnel for secure data transfer between the device and the server. This technology reduces the possibility of identity theft and makes it harder to try to find the user's location.

To use a VPN, you need to install a special client program on your gadget. Such software exists for mobile devices and computers. But some routers can also be connected to VPN services. This feature allows you to protect all gadgets in the local Wi-Fi network at once, even if they do not have special programs.

Whether your router supports VPN, you can find out in the instructions or on the manufacturer's website. The same applies to the necessary settings.

Privacy Protection WiFi networks- This crucial point when creating a homegroup. The fact is that the access point has a fairly large range, which can be used by attackers. What to do to prevent this? How to protect a private wireless network from attacks by unscrupulous people? This is what will be discussed in this article.

How to secure home WiFi networks

Before moving on to the question of how to secure a private home WiFi network, you should understand how it works. So, to organize a home wireless network, as a rule, a router is used that acts as an access point. In order to become a member of the group, you must connect to it.

This suggests that in order to protect confidential information, it is necessary to close access to the router to unauthorized people. How it's done? There are several points here:

• long and complex password to enter the router settings menu.
• A strong password for connecting to a Wi-Fi network.
• Select a secure encryption type.
• Using a MAC filter.
• Access settings in the operating system.

As you can see, there are a lot of security settings. This is necessary, as the protection of the privacy of the Wi-Fi network depends on it. However, most of them are in the parameters of the router.

So, let's look at all these points in order.

WiFi Network Security: Video

Key to enter the router settings menu

Since almost all security settings are installed in the router, we need to come up with a complex password to enter the parameters system. In addition, a login is used here, which must also be original and complex. How to do it?

First of all, it is worth noting that each router has a different interface, but the principle of operation is almost the same for all. We will analyze how to change the password for logging in to the router using the D-LinkDIR-615 model as an example.

First, connect to the router by wireless communication or via cable. After that, open any browser and write the address of your router in the address bar. It is indicated on the bottom cover of the device, as well as in the instructions.

How to easily find out the IP address of a WiFi router: Video

In the vast majority, this is the next address - 192.168.0.1 (such addresses can also be used - 192.168.1.1 or 192.168.2.1).

After entering the address, the system will prompt you to enter a username and password. Initially specified admin, admin respectively. It is these values ​​that will now need to be changed, since the manufacturer uses an insecure login and key, so that the user can easily enter the settings and change the data at his discretion.

After entering, press "Enter". So we got into the router settings menu. At the bottom of the screen, click "Advanced Settings". Several additional sections will appear, among which you need to find "System" and select "Administrator Password" in it. This is the key that we need to change.

In the window that appears, simply enter New Password and confirm it. Next, just click Apply. This completes the key change process, and now the protection of the home wireless wifi the network has grown.

How to find out the password for your WiFi connection in the router settings: Video

Please note that this router model does not allow you to change the administrator login. However, devices from other manufacturers or even just other models allow you to set any login to log into the system.

WiFi network key

Very important parameter, on which the protection of information in Wi-Fi networks depends - this is the network password. It prevents unauthorized intruders from connecting to the router using a wireless connection. That is why the network key must be long and complex.

It should be noted that initially there is no Wi-Fi connection protection on the router at all. In other words, anyone who is in the coverage area can connect to the device without entering passwords.

To fix this, we need to return to the router settings menu. Now we are interested in the "WiFi" section, in which we need to find and open the security settings. In the window that opens, we will need to select the type of encryption (type of authentication). It is also an important parameter that affects network security.

So, choose the type of encryption WPA-PSKWPA2-PSKmixed. This is the recommended secure form of authentication and provides the most reliable protection. A line will appear below in which you need to enter the network key. We enter the invented values. It is recommended to use a mixture of Latin letters and numbers. Moreover, the number of characters must be at least 8-12.

router MAC filter

Each device equipped network adapters, computer, laptop, smartphone, tablet and so on, has a unique MAC address. In order to increase network security, it is recommended to install a filter for such addresses. In other words, in the router settings, you can allow only trusted devices to connect by specifying their addresses.

To do this, we again enter the router settings menu. In the "WiFi" section, find the MAC filter and open it. The window that appears has two tabs:

• Filter mode.
• MAC addresses.

The first is the mode. Here you can choose one of three options:

• Allow - the specified MAC addresses will be allowed access to the network. Everyone else will not be able to connect to the group.
• Deny - denies access to the network to the specified addresses.
• Disable - the filter mode is disabled.

In the first tab, select the appropriate mode. And in the second we enter the necessary MAC addresses. If you selected the "Allow" mode, then you need to enter the addresses of only trusted computers. If the "Disable" mode is set, then you need to enter only the addresses of foreign PCs.

How to set up a MAC filter in a router: Video

Setting up OS access

The operating system also has built-in data protection. In order to increase protection, we need to enter the network and sharing center. This is done by pressing right click mouse on the connection icon in the tray.

In the window that opens, open the item "Change settings public access". We will open a menu where you can configure access, enable or disable PC discovery on the network, and much more. The first step is to enable password protected access. In this case, the system will automatically generate a complex password. Write it down, because if you later want to provide access to any files, you will need it.

In order to set up maximum protection system, you should disable access at all points. There is nothing complicated here, carefully read the prompts on the screen.

So, now you know how to protect your private WiFi network from intruders. Now no one else can connect to your group and harm information or steal important data.

How to determine who is connected to the network

We figured out the security settings. Now we can move on to the question of how to determine who will connect to my home WiFi networks. Everything is very simple. The router registers the MAC address of each group member. Therefore, we just have to enter the router settings and see the statistics. We are again interested in the "WiFi" section, only now we select the "Station list" item. If a TP-LINK router is used, then the "Statistics" section is needed.

The station list displays the MAC addresses of everyone who is currently connected to the network. Here you can disconnect a particular connection. As we already know, each computer has a unique MAC address. Now you know how to check who is connected to my private WiFi network.

To find out the value that the computer uses, just log into the network control center. In the center of the screen that appears, you will see your connection. In the right half you will see the "Connect or disconnect" section, and a little lower - the type of access and connection. Click on the type of connection and select "Details" in the menu that appears. Here you will find the line "Physical Address". This is the MAC address of your network adapter.

How to find out who is using my WiFi: Video

I have over 10 years of experience in the IT field. I am engaged in the design and configuration of commissioning. He also has extensive experience in building networks, system administration and working with ACS and video surveillance systems.
I work as a specialist in the company "Techno-Master".

In this article, I will talk about blocking Wi-Fi clients that are connected to the router. Simply put, I will show you how to block a connected device by MAC address in the settings of your router. Or block absolutely all devices, and allow only some to connect. It's not strange that the article is across tp-link router is very popular. It is not uncommon to have to restrict access to the Internet through a router for a device, or completely block it.

Let's take a closer look at blocking devices by MAC addresses on Asus, Tp-Link, D-link and Zyxel routers. In them, this function is implemented, although each manufacturer has its own way. But don't worry, it's not hard to figure it out. Most importantly, you must have access to the router settings. I will not describe here why such a blocking can be useful, there are actually a lot of options. By the way, you can block absolutely any device from connecting to your Wi-Fi: smartphone, tablet, laptop, etc.

Generally, there are two ways you can block Wi-Fi clients:

• block absolutely all devices, no one will be able to connect to your router, and allow only necessary devices (MAC addresses of devices). This method is great for additional protection of the Wi-Fi network. Paired with a good password, this lock will make your wireless network very secure. But, if you often connect new devices, then this is not very convenient, since you will have to register their MAC addresses each time.
• Well, the second method, which is used most often, is blocking certain Wi-Fi network clients. For example, in your home, 10 devices are connected to the router, and you want to block the Internet (connection) for one of them.

If you want to block a device that is not currently connected to your Wi-Fi network, then you need to find out its MAC address. If this mobile device, then you can see it in the settings, usually on the "About device" tab, etc. If you need to find out the MAC address wireless adapter laptop, then in the command line you need to run the command ipconfig /all. Information will appear where the Physical address of the wireless adapter will be indicated. Just do not confuse it with a network card.

Let's take a closer look at the process itself on different routers. Look for the instructions below for your router, and follow the instructions.

Blocking devices by MAC address on an Asus router

Connect to the router, and open the settings at 192.168.1.1. Or, see the details on entering the control panel. In settings go to the tab Wireless network – Wireless MAC Filter.

Opposite point Enable MAC address filter set the switch to position Yes. On the menu MAC address filtering mode you can choose to Reject or Accept. There is an input, devices that we will add to the list. If choose Accept, then absolutely all devices will be blocked, except for those that you add to the list. Most likely you should leave Reject to block only some clients.

The added client will appear in the list. To save, click on the button Apply. The device will be disconnected from your Wi-Fi network and will not be able to connect to it until you unlock it.

To remove the lock, press the button in front of the device Delete (-), and press Apply. At Asus, this function is implemented very simply and clearly. I think you will agree with me.

We block Wi-Fi clients by MAC address on the Tp-Link router

Already according to the standard scheme,. Go to tab Wireless – Wireless MAC Filtering. Click on the button enable to enable filtering.

By default it will be set Deny, this means that only those devices that you specify will be blocked. If choose allow, then absolutely all devices will be blocked. Click on the button Add new... to add a new device.

In field MAC address enter the address of the device you want to block.

To see the currently connected devices and their addresses on the Tp-Link router, go to the DHCP tab - DHCP Client List. There you can copy the MAC address of the desired client.

In field Description write an arbitrary name for the rule. On the contrary Status we leave Enabled (meaning the rule is enabled). To save click on the button Save.

The created rule will appear. You can delete it or change it by clicking on the appropriate links next to it. Or, create a new rule for another client.

To unlock the device back, just delete the rule, or edit it, and change the Status to Disabled.

How to disable a Wi-Fi device on a D-Link router?

So, now we will block clients on . We go into the settings at 192.168.0.1. If you are doing it for the first time, or if it doesn’t work, then see the instructions. In the settings, go to the tab WiFi – MAC filter – Filter Mode. On the menu opposite MAC Filter Restriction Mode, select one of the two options: Allow or Deny.

If you want to block one or more clients, then select Forbid. And if you want to block absolutely all Wi-Fi connections, except for those devices that you add to the list, then select Allow. Click on the button Apply.

Next, go to the tab MAC filter – MAC addresses. And choose from the list (devices that are connected) the device we want to block. Or press the button add, and specify the address manually. We press the button Apply.

Added devices will appear in the list and will not be able to connect to your network. You can remove them from the list, or add new ones.

This is how it is set up D-Link routers. Everything is simple, it's just a pity that the device name is not displayed in the list near the address. It's hard to figure out who to block.

Control Wi-Fi clients by MAC addresses on Zyxel

Let's take a look at setting up MAC filtering on devices ZyXEL Keenetic. Go to your router settings. First, we need to register the required device on the home network. To do this, go to the tab below home network , click in the list on desired device, and click on the button Register.

Next, go to the tab WiFi network , and open the tab at the top Access List. First of all, in the Blocking mode field, select the one that suits you. White list – block all devices except those in the list. Black list- block only those clients who are in the peep.

Select the checkbox for the device you want to block and press the button Apply.

After that, the client will be disconnected from the router and will not be able to connect again.

To remove a device from the black list, just uncheck the box and Apply settings.

That's all the instructions.

It may be that you accidentally block yourself. In this case, go to the settings by connecting to the router using a cable, or from another device, and remove your device from the list. If it doesn't work, you can reset the router settings.

I hope my instructions were helpful to you. Good luck!

Wi-Fi has become so popular that having a router is the rule rather than the exception. But, despite all the conveniences, it should be taken into account that it is visible to others. See for yourself how much is displayed in your home available connections. It is unlikely that one or two, usually their number reaches a dozen or more. Similarly, neighbors can see your network among others available.

Few people want strangers to access their personal wireless network

But if certain precautions are not followed, outsiders will be able to connect to your connection. What is the risk? At least the loss of Internet speed. You will not receive full speed your communication channel if someone connects to it at your expense. But the situation is much more dangerous if an attacker connects to your Wi-Fi, who can use the transmitted data to his advantage.

In order not to be exposed to such a risk, you need to limit access to your Wi-Fi. Read below for tips on how to do this.

Internet access for a specific list of devices

What is a mac address and how to find it

To each network device even during manufacture at the factory, a special mac-address is assigned - a kind of unique digital fingerprint. It looks like "A4-DB-30-01-D9-43". For further settings, you need to know the mac-address of a single device to which you are going to provide access to Wi-Fi. How to find it?

Windows

Option 1. Through the "Network Control Center"

• Between the battery and sound icons is the internet connection icon. Right-click - select "Network and Sharing Center".
• " View active networks" - "Connections" line, click on the connection name - "Details".
• In the line "Physical address" and the mac-address of the laptop will be presented.

Option 2. Through "Settings" (for Windows 10)

• Click "Start" - "Settings" - "Network and Internet" - "Wi-Fi" - " Extra options" - "Properties".
• "Physical address" is the mac address of the laptop.

Option 3. Through the command line

• Hold Win + R - type cmd (or Win + X - Command line(administrator) on Windows 8.1 and 10).
• Type the ipconfig /all command.
• Under "Wireless Adapter" local network. Wireless network" in the line "Physical address" contains the required information.

Android

• "Settings" - " Wireless network» - «Wi-Fi» - menu button - «Additional functions».
• The required data is in the MAC address line.

iOS

"Settings" - "General" - "About this device" - "Wi-Fi address".

Once you have located the device ID, write it down or just remember it. Now let's proceed to the next stage - we will establish access to the required equipment through the router.

Setting up a router

Log in to the settings web interface first. Using a browser, go to 192.168.0.1 or 192.168.1.1. Enter your login and password - admin/admin or admin/parol. These combinations work on most devices. If there is no access, check the information on the bottom surface of the router or in the instructions for it.

The location of the menu items may differ depending on the manufacturer, but basic principles applicable to all devices.

1. In the "Wi-Fi network settings" section, enable filtering by mac-address, because it is initially disabled.
2. In the "MAC Address Filtering" tab, add the addresses of the devices that you are going to provide access to Wi-Fi.

Now you can use Wi-Fi only through those devices with which you have booked addresses. Attackers will not get access to your data.

Other options for restricting access

Replacing the network and router password

If you haven't changed your Wi-Fi password, change it. And it is advisable to do this regularly. Create a new password in the network security settings. It is equally important to replace both the factory password and the login login when installing the router. The standard combination is the easiest way to access a connection.
