Wi-Fi only works when the computer is on. Why does Wi-Fi only work when the computer (PC) is turned on? Disable battery saving

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 supply 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.

Today I decided to talk about one not very popular problem that is sometimes encountered when setting up a Wi-Fi router. The situation is this: we install a Wi-Fi router, configure it, the Internet works on all devices, both via cable and Wi-Fi. But when we turn off the desktop computer (or even a laptop), which is connected to the router via a network cable, then the Internet connection is lost on all devices. That is, there is a connection to the Wi-Fi network, but the Internet does not work. It turns out that the router distributes the Internet only when the desktop computer is turned on. We turn off the PC, the router stops distributing the Internet.

Let me tell you right away that it shouldn’t be like this. A router is an independent device; it distributes the Internet without connecting to any device, and does not depend on computers in any way. If you have the problem described above, then the problem is most likely due to incorrect settings of your Wi-Fi router. It is in setting up a connection to an Internet provider (WAN).

Internet via router does not work after turning off computer

1 Most likely, you have an Internet connection via PPPoE, or PPTP. That's the whole point. To connect to the Internet, you need to have a high-speed connection on your computer. The connection itself goes through a login and password. And the problem is that after installing the router, you continue to launch this connection. But you don’t need to do this, I’ll explain now.

The connection that was configured on your computer does not need to be started after installing the router. This the connection needs to be configured on the router, this is a very important point! That is, in the router settings you must select the connection type and set the necessary parameters for connecting to the Internet. When the router itself establishes a connection to the provider, it will distribute the Internet to all your devices, including your computer via cable. And the high-speed connection on your computer can be removed.

If anything, ask in the comments, I’ll try to help with advice.

2 The problem is in the MAC address. This is another reason why the router may stop distributing the Internet after turning off the computer. Here you need to know for sure whether your provider binds by MAC address. You can check with your provider's support.

If there is a MAC binding, then there are two options:

Call your Internet provider support and ask for a new MAC address. Your router address. It is indicated on the router itself, on a sticker. With some providers, you can do this yourself, through your personal account.
And the second one is to clone the MAC address on the router from the computer to which the Internet was connected. You can do this yourself in the router settings. But, you must connect the router to the computer whose MAC address you want to clone. I wrote about this in more detail in the article How to clone (change) the MAC address of a router, and how to find out the MAC address?

Conclusions

Perhaps there are some other reasons why the operation of the router may depend on the computer. But, I think that first of all this is an incorrect router configuration. That is, when an Internet connection is launched on a computer, then the Internet, of course, is on the router. When the computer is turned off, the Internet on the router disappears, and it is not disconnected. It's simple.

Internet via router does not work after turning off computer

And once again: the main thing is to set the correct parameters for connecting to the Internet provider. If you don’t know where to specify these settings on your router, then see the instructions for setting up the router. You can look it up on our website, on this page. Basically, these settings need to be set on the “WAN” or “Internet” tab. This is what these settings look like on a TP-Link router:

Greetings, dear friends!

Here is one of the comments:

Strange situation, isn't it? To be honest, I didn’t know the exact solution, and I still don’t know :).

There were thoughts that it was the provider who simply carried out authorization through the computer. And if you turn off the computer, the Internet on the Wi-Fi router disappears. But these were just guesses and I kept them to myself.

Each provider uses its own trick to authorize clients, different settings, technologies, etc.

But, as it turned out, my guesses were not entirely far from solving this problem. Author of the comment (which is in the screenshot above) shared his solution with me, for which I thank him very much!

Unfortunately, I wasn’t able to ask him in more detail, but here’s what helped him get rid of the network interruption when turning off the computer:

This is the solution! I think the whole problem was with the static IP address. It most likely was not registered in the router, but was registered in the local network connection properties on the computer. And when the computer was turned on, the provider received this IP and the Internet worked. And when the computer was turned off (unplugged) the Internet did not work.

Or is it all about the MAC address, which I also recommend immediately cloning to the router. Although, it could be anything.

See the article on how to properly configure your router to work with your Internet provider -

The best solution in such a situation is to call the support service of your provider. They should deal with such issues, and not you suffer and spend hours looking for solutions on the Internet.

I'm still going to write an article about how the support service (not only the provider) in most cases it helps to solve various problems in short lines. I don’t understand why, when users can’t set something up or doesn’t work, they start looking for a solution to the problem themselves, rather than asking support from the manufacturer, provider, etc.

Somehow I got off topic. In short, you understand, right? We call support and require a meaningful answer. If they don’t want to help with anything and can’t help, then Google the problem, or go straight to this site and ask me :).

Sorry for not giving precise instructions on how to solve the problem with the lack of Internet on the router when the router is disconnected from the computer. And most likely, there is no exact solution to this problem. Everything is individual. After all, routers, providers, technologies, settings - everything is different.
