Automatically disable Wi-Fi when connected to an Ethernet network. Why does Wi-Fi turn off?

Now it’s difficult for us to imagine a full life without wireless Internet access. A sea of information and entertainment is available at home, in offices, in shopping malls and other places from any device that supports Wi-Fi technology. It is very convenient and practical. But every owner of a router may have an urgent need to stop distributing a wireless signal from their device for various reasons. How can this be done?

To disable the wireless signal from your router, you need to make changes to the configuration of the network device. If you want to leave access to Wi-Fi only to yourself or selected users, you can enable and configure filtering by MAC, URL or IP address. Let's take a closer look at both options using equipment from TP-LINK as an example.

Option 1: Disabling Wi-Fi distribution on the router

Turning off Wi-Fi on the router is extremely simple; you need to log into the device’s web interface, find the desired parameter and change its state. These actions should not cause any insurmountable difficulties for the average user.

Option 2: Configure MAC Address Filtering

If you wish, you can disable Wi-Fi only for individual users on the local network. To do this, the router configuration contains special tools. Let's try to enable filtering on our router and leave wireless access only to ourselves. As an example, we use a computer with Windows 8 installed.

First you need to clarify your MAC address. Right-click on "Start" and in the context menu select the item "Command Prompt (Administrator)".

In the command line that opens, type: getmac and press the key Enter.

Let's look at the results. Rewrite or remember a combination of numbers and letters from a block "Physical Address".

Then we open an Internet browser, enter the IP address of the router, go through user authentication and get into the web client of the network device. Select a section in the left column "Wireless Mode".

In the drop-down submenu, feel free to go to the page "MAC Address Filtering". All the settings we need are there.

Now you need to enable the wireless MAC address filtering service on the router.

We decide on filtering rules, that is, to prohibit or, conversely, to allow wireless access to stations that we will add to the lists. Place a check mark in the appropriate field.

If necessary, confirm your choice of rule in a small window.

On the next tab, write your MAC address, which we previously found out, and click on the button "Save".

The problem is solved. Now you will have wireless access to the router, while other users will only have wired access.

Let's summarize. You can disable Wi-Fi on your router completely or for individual subscribers. This can be done without much difficulty and independently. So take full advantage of this opportunity.

Nowadays, it is almost impossible to imagine life without the Internet. And one of its main components is the Wi-Fi wireless network. Previously, everyone thought that an Internet connection via a network cable was reliable, fast and inexpensive. Now this opinion has not changed, but the competitor in the form of Wi-Fi has gained many more fans.

It is easier for people to connect to the Internet via a Wi-Fi connection than to look for a wire, then insert it into special connectors and only then do what they intended. Take the same laptop or phone. These devices have built-in modems that allow you to connect to the Internet in the blink of an eye, just know the selected network.

In recent years, a stereotype has emerged that there is no point in turning off Wi-Fi, because you may need it at the most unexpected time. There is no point in arguing with this, but if you want to turn off Wi-Fi on the same laptop, we will tell you how to do it correctly.

Instructions

Every laptop has a combination, after pressing which all network connections are interrupted. But you only denied the laptop access to Wi-Fi, and did not turn it off. In order to completely turn off Wi-Fi on a laptop, you must perform the following steps:

go to the Network and Sharing Center;
after entering there, find the inscription “ Changing adapter settings» and click on it with the left mouse button;
we will see a list of all available connections. Among them you need to find the one marked as “ Wireless" By right-clicking on it and selecting “ Disable", it is usually located first in the window that opens, you turn off Wi-Fi on your laptop.

To check if it is valid, pay attention to the network connections icon that is located in the tray. There you should see a network icon crossed out with a red cross.

To enable the wireless connection, follow the same steps, only instead of “ Disable» click « Turn on».

In order to disable Wi-Fi on the router, you need to log into the web interface, find the function responsible for wireless communication there, and disable it. First, let's talk about how to log into the web interface.

Login to the router's web interface is done using a browser. To do this, you can use any browser convenient for you. Open your browser and enter into the browser's address bar.

If you don’t know what IP address your router is accessible at, then just try entering 192.168.0.1 first, and then 192.168.1.1. In most cases, the router will be accessible at one of these addresses.

After entering the correct IP address, a form for entering your login and password will appear on the screen. Depending on the model of your router, this form may look different. For example, this is how it looks on D-Link routers.

In this form you need to enter the login and password for the router and press the enter key. If the login and password are correct, then the web interface will open in front of you. If you have any difficulties logging into the web interface, you can familiarize yourself with this.

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

After logging into the web interface of the D-link router, you need to go to the section with WiFi settings. To do this, open the “SETUP” tab and go to the “Wireless Settings” section. Next you need to move on to manually managing the Wi-Fi network settings. To do this, click on the “Manual Wireless Connection Setup” button.

After this, you should see a page with Wi-Fi settings. Here you just need to uncheck the boxes next to the “Enable Wireless” items and save the settings by clicking on the “Save Settings” button.

Please note that if your D-Link router supports the 5 GHz band, then to completely disable Wi-Fi you need to uncheck two boxes. One in the block with settings for the 2.4 GHz band, and one in the block with settings for the 5 GHz band. If the router does not support the 5 GHz band, then to disable Wi-Fi it will be enough to uncheck one box.

How to disable Wi-Fi on a TP-LINK router

After logging into the web interface of the TP-LINK router, you need to go to the section with Wi-Fi settings. In the web interface of the TP-LINK router, this section is called “Wireless Settings”.

In the “Wireless Settings” section, you need to uncheck the “Enable Wireless Router Radio” function and save the settings by clicking on the “Save” button.

Some models of TP-LINK routers have a special button on the case to turn Wi-Fi on and off. In this case, it will not be possible to disable Wi-Fi via the web interface.

How to disable Wi-Fi on an ASUS router

To disable Wi-Fi on an ASUS router, you need to open the web interface and go to the “Wireless – Professional” section. In this section you need to disable the router radio module. To do this, you need to switch the “Enable Radio” parameter to the “No” position, and then apply the settings by clicking on the “Apply” button.

Please note that radio modules for the 2.4 and 5 GHz bands are disabled separately. Therefore, if your ASUS router supports 5 GHz, then you need to first disable the 2.4 GHz radio module, then go to the 5 GHz settings and disable the radio module again.

On a laptop. Thus, the connection to the Internet is broken, important notifications and alerts do not arrive, but, as you know, it is impossible to live without the Internet. Many blame device manufacturers for this - laptop or router, although the problem is most often easily solved with a couple of mouse clicks.

Today we will study the main possible reasons for the occurrence of such a situation, and find out what to do if WiFi on a laptop stops working.

WiFi turns off on a laptop - we solve the problem!

If the laptop’s connection to the Internet via WiFi is unstable and constantly breaks down, then there may be several reasons for this - either certain operating system settings, a device malfunction, or poor communication from the provider or cellular network operator.

Perhaps you should also pay attention to this video to understand what factors affect the stability of the WiFi connection.

Disable battery saving

The main reason why WiFi constantly turns off on laptops lies in the power and energy saving settings. Since a laptop is a battery-powered mobile device, manufacturers are trying to reduce the power consumption of the device in favor of greater autonomy and longer battery life.

By default, device performance when running on battery power is slightly reduced in favor of energy saving. Also, to avoid wasting electricity on unused functions, the operating system turns off some computer components. For example, if the WiFi connection is idle or not actively used, the WiFi adapter can be disabled to save power. Therefore, your favorite laptop, left unattended, carefully disables unnecessary functions and deprives you of a stable connection to the Internet.

Power settings are located in the control panel. However, please note that the manufacturer often installs additional programs that allow you to control power consumption, and the reason for WiFi turning off may be hidden in them.

Open the taskbar and select Power Options. The control panel and the item we need can be easily found using the search.

In the power supply window that opens, you can see which power management scheme is currently active for you, and also proceed to its detailed settings.

In the window that opens, you can configure the screen timeout and sleep timeout. We are interested in the point that changes additional power options.

Find the item responsible for WiFi operation. Here it is long called a wireless network adapter. Change the value to high performance.

After changing the power plan, reboot your device and check if the problem is resolved.

Reboot the router

If the problem persists, rebooting the router may help. The easiest way is to turn off the power and turn on the device.

You can also reboot the device through the administration panel by going to 192.168.0.1 or 192.168.1.1 in your browser, entering your username and password, and clicking the appropriate button. The exact address and reboot method depend on the device model, and the login and password must be changed from standard admin/admin to your personal ones.

Checking the network signal and the stability of the Internet connection

We discussed how to increase the speed of a wi-fi router and the Internet in one of the previous articles. In our situation, it’s worth paying attention to how far the router is from the laptop and what obstacles the signal passes through.

If, in addition to WiFi, the Internet is unstable over a wired connection, it may be worth calling your provider and resolving the issue of poor Internet with them.

Internet speed can be easily checked using an online service speedtest.net- after all, if the values differ from those declared by the provider to a lesser extent, this is a reason to be puzzled by the quality and level of the signal.

Reinstalling the driver

Reinstalling the wireless adapter driver may also help. To do this you need to do the following:

go to the website of your laptop manufacturer;
enter the model of your device;
select the operating system;
download the latest version and install the new driver.

The method for downloading software varies depending on the device manufacturer and model. Try to download the latest versions of drivers for your operating system and device.

We have looked at the most popular reasons that lead to laptop WiFi constantly turning off. It’s good if the problem was solved by changing the power plan, and the performance of both the router and the laptop does not raise any questions. If the problem cannot be solved, it may be worth contacting a specialist.
