To connect wi-fi to laptops of various models and different manufacturers You can use your own original key combination. Detailed description For specific model you need to look in the user manual that came with the laptop. The FN button is found on almost all models of modern laptops. It helps you connect various functions and connecting the beech with other devices. If there is no FN button on the laptop, then to turn it on wireless network a special button or switch is used. As a rule, it is indicated by one of these drawings.

If you don't find it on the keyboard, examine the ends of the laptop; perhaps the switch is on the side. Also, take a close look at the bottom of your laptop. There are models in which the switch is located on the bottom cover. Moreover, manufacturers make this button barely noticeable. It practically merges with the body and may not be visible at first glance. It may be signed Wireles or Wlan. Have you turned on wifi using the required button or combination, but it doesn’t work?

How to set up wifi on a Windows 7 laptop

Before setting up, you need to check the availability and connection of drivers. Checking drivers Checking the driver is to find out whether they are on your device at all and whether it is involved in this moment. So, in Control panels select an item device Manager, which can be hidden inside the item Equipment and sound.

A window opens in which we find Network adapters . There must be two items: Ethernet and Wi-Fi. One of them should have the word “Wireless” in its name. This is your adapter.

If there is no entry about the wi-fi adapter, or there is an icon next to it with exclamation mark on yellow background, this means that you have a problem with your drivers. If there is no entry, it means that the drivers are not installed and you will have to install them from the disk that came with the laptop. Or find it on the manufacturer's website. Without them, wi-fi will not work. If there is an entry, but next to it there is a yellow exclamation mark, click on this item right click mice. In the window that appears, select “Engage”. The reason for connection difficulties may lie in the fact that the adapter is set to a power saving mode. To disable it, right-click on it, then Properties - Power Management, now you need to uncheck the box “Allow the computer to turn off this device to save energy.”

Now everything is fine with the driver. Enabling the adapterwi- fi . To do this through Control Panel→ Network and Internet go to Network connections. Here we find Wireless network connection . This is the wi-fi adapter. Right-click to open the dialog box and select “Enable”. Connect to an access point. All that remains is to connect the laptop to the access point. Make sure the access point is active. Find it in the lower right corner of the screen in the taskbar wifi icon. When clicked, the network management window will open, select the desired network, click Connect.

If the network is protected by a password, the system will ask you to enter it (if you have forgotten the password for your network, you can find it in several ways). Only after entering the required password will you be able to use the Internet. If the network is open, the connection will occur automatically. That's all. Enabling and setting up Wifi on a laptop completed. If you have set up Wi-Fi once, you won’t need to do this anymore, since they will automatically be saved in the laptop’s memory. You will only need to turn it on with the appropriate button or key combination. Remember that connecting wirelessly takes a lot of power from your device, so the battery will be used quite intensively. Have a nice and simple connections no adventures!

I will show and tell you how to turn on Wi-Fi on a laptop or computer.

1. Turn on Wi-Fi using the FN combination

I have on Samsung laptop NP-R560 can turn on Wi-Fi using the Fn + F9 keys. You can also turn it off. If you have the Fn key, then perhaps you can also turn on Wi-Fi by pressing the Fn key and some other key (from F1 to F12). Look for the wireless network icon on the F1 to F12 key.

If the Fn key on your laptop does not work, then in this lesson I talked about it.
Sometimes, in order for the Fn key to work, you need to install a program for it.

Sometimes the key turn on Wi-Fi may be located separately.

2. Enable Wi-Fi by updating drivers

If you can't turn on Wi-Fi or Wi-Fi device not detected, then you may need to update your Wi-Fi driver. You can update drivers from using Driver Genius, Auslogics Driver Updater, Reviversoft Driver Reviver, DriverPack Solution and there are many more programs for updating drivers.

Download Driver Genius you can from the official website bluesquad.revenuewire.net/dg-pro/download.

3. Enable Wi-Fi through BIOS

To enter the BIOS, you need to restart or turn off the computer, then when you turn on the computer at the very beginning, when it is just starting up, a text is usually displayed on the bottom left that indicates which key to press to enter the BIOS. On my Smasung laptop, to enter the BIOS you need to press Delete key. On other laptops and computers, these may be the F1, F2, F8, Esc, F10, F11, F12 keys. Sometimes you need to press keyboard shortcuts to enter the BIOS. Try the Fn, Ctrl, Alt, Shift key combination.

Typically, how to enter the BIOS is indicated at the bottom of the boot screen.

So, having entered the BIOS, we find there Wireless Device Control (Control wireless devices) if Last Status is there, this means that after a reboot, Wi-Fi and Bluetooth will be turned on again if they were turned on before the reboot, or will be turned off if they were turned off before the reboot.

If Wireless Device Control is set to Always Off, then Wi-Fi and Bluetooth will always be turned off when the computer boots.

If Wireless Device Control is set to Always On, then Wi-Fi and Bluetooth will always be turned on when the computer boots. This is what we need, it will be easier so that when you boot the PC and you always have Wi-Fi on.

Other lessons on Wi-Fi:

There's a whole problem with the laptop. This fate has not passed for the owners of laptops from Acer. Many have already racked their brains, thinking about how to enable Wi-Fi on an Acer laptop. Especially if the transmitter is set to Off by default. It should be noted that the method depends on the specific device model. Unfortunately, there is no universal recipe. That is why all possible options should be considered in detail.

A little about Acer

This Philippine company appeared a long time ago and managed to win the sympathy of many PC and laptop users. Initially, the company specialized in the production of cheap components for American giants such as Intel and Apple. But over time, the company's management decided to compete with them. What can I say, the competitor turned out to be serious. Now a good part of the computer market belongs to Acer. Who would have thought?

A little history: Wi-Fi

Wi-Fi is a technology for transmitting data wirelessly. This is very convenient because it frees PC and laptop users from using outdated wires that always get tangled underfoot. Wi-Fi was first used in a production laptop in 2000. At that time this was very rare. And there wasn’t much point in having a transmitter in a laptop, since wireless points there was very little access. By 2002 the situation was changing. Wireless Internet has begun to gain popularity. Well, now you can see for yourself how it ended. None mobile device can't do without a Wi-Fi transmitter.

Wi-Fi standards

The most common Wi-Fi adapter standards are b, n, g And ac. The first three are no different from each other. But ac noticeably stands out in terms of data transfer speed. It is several times higher than that of standard b-, n-, g-adapters. Now many manufacturers install standard transmitters in their devices ac. The most common Wi-Fi frequency is 2.4 GHz. Everything would be fine, but Bluetooth works at this frequency. As well as microwaves and much more. All this interferes with the purity of the channel. But Wi-Fi technology is gradually moving to the 5 GHz frequency. It's already there wireless internet nothing will interfere. But we digress. How to enable Wi-Fi on an Acer laptop? Let's look at this topic step by step.

What should you do first?

In some cases, problems with the Wi-Fi transmitter have nothing to do with the laptop model. It's all about the inattention and carelessness of some users. The most common problem with Wi-Fi is the lack of installed drivers for the adapter. If this is the case, then there is no problem here. Just download necessary drivers from the manufacturer's official website and install them. The Acer page contains programs for any device. Therefore, this can not be considered a problem. It is very important to download the driver specifically for your laptop model. The point is that the universal software does not exist because the manufacturer installs Various types and types of adapters for your devices. Therefore, you should not hope that a driver from Acer Ferrari will fit the Acer Aspire.

Go ahead

If after installation Wi-Fi drivers It still doesn’t start, so we continue to look for the problem. Models such as Acer 1000, 1690, 2012, 5610 have special button inclusions. It can be located anywhere: on the side, behind, in front, above the keyboard. If Wi-Fi does not work on your Acer laptop, it makes sense to look for such a button.

The most interesting thing is that she can look like anything. Some models show an antenna on the button. If so, then finding the switch will not be difficult. But in most models there is a very ordinary key that you need to find and press. The buttons on some Acer laptop models have light indication, which is very convenient. There is no need to rack your brain over whether the transmitter is turned on or not.

If there is no button

It also happens that a physical switch (or is missing altogether. In this case, let's turn to the rich Key combinations can turn on and off the most different devices laptop. Only the specific combination depends on the model. If we are dealing with model range"Acer Aspire One", then to turn on Wi-Fi you need to use the Fn+F3 key combination. Most other Acer models use the Fn+F5 combination. If these combinations do not work, you need to try to find the right combination by the “scientific poke” method.

It is also worth paying attention to the fact that in various models displayed differently. It can be represented either by the letters themselves or by some incomprehensible symbol. If the Fn inscription is nowhere to be seen, feel free to press all the incomprehensible buttons. You still won’t be able to cause much harm to the system and laptop through your actions. As a result, the desired combination will be found. If the Acer laptop does not see Wi-Fi even after this, then move on to the next point.

If Wi-Fi still doesn't work...

In this case, let's turn to systemic ways turning on the adapter. In Windows 7 and 8, the icon with the image of the WLAN adapter is located in the system tray at the bottom, on the right side. You need to right-click on the image and select “Network and Sharing Center” shared access" There we click on the item “Change adapter settings”. We look for the name of your WLAN device and right-click on it. In the menu that appears, click “Enable”. Then close all windows.

After all of the above has been done, click on the WLAN icon in the system tray with the left mouse button. Then select the name of your Wi-Fi network and enter the password to connect. After all these manipulations wireless access Internet connection should work. However, that's not all.

Additional software from the manufacturer

If Wi-Fi still doesn't pick up, it means your device is equipped with additional utilities, which control adapters. Acer (laptop) usually “hides” the programs used for this so that incompetent users do not mess with the settings. You should open Start, select All Programs and see if there is anything unusual with the Wi-Fi or WLAN sections. If available, then you should enable these utilities. Because without them, the operation of the wireless adapter is impossible. If all of the above did not help, then such a laptop is on its way to service center, since by all indications there is a problem in the adapter itself at the hardware level. But you did your best. Now let the experts figure out how to enable Wi-Fi on an Acer laptop.

Results

Now we can summarize. What was learned from our little educational program? Let's determine step by step the procedure for turning on the adapter in Acer laptops:

1. We check the availability of the necessary drivers.
2. If they are there, look for the hardware power button.
3. When it is not there, we select a key combination on the keyboard.
4. If this does not help, try to enable the adapter systemically.
5. Does not work? Are looking for specialized programs from the developer.

Everything seems simple. Now you know what you need to do to provide yourself with wireless Internet access. And for many, information about which keys to turn on WiFi on a laptop will be very useful. After all, it can also be turned off in order to save battery power.

Conclusion

As an example, we looked at devices from Acer. However, the algorithm of actions for laptops from other manufacturers is almost the same. There are only minor changes to the button placement. Thanks to this article, you can easily set up Wi-Fi on any device. Now you know how to turn on Wi-Fi on an Acer laptop. Go for it - and you will succeed.

Hello! Today we’ll look at enabling Wi-Fi on laptops that run Windows 7. For some reason, many people ask these questions. But as a rule, Wi-Fi on a laptop is turned on by default. That is, if the driver is installed, you can immediately connect to Wi-Fi networks. You don’t need to make any special settings, and you don’t have to turn on Wi-Fi on your laptop in any special way. No, of course there are different cases and problems when you can’t connect to Wi-Fi without dancing with a tambourine. Now let's look at everything in detail.

If you are faced with the problem of turning on Wi-Fi, then your Internet connection status will most likely be like this:

If the network icon is simply crossed out with a red cross, then there are no available services within the radius. Wi-Fi connections networks.

Before moving on to any instructions, let's understand what is enabling Wi-Fi on a laptop, and turning on Wi-Fi on Windows 7 (in the very operating system) , these are different things. Therefore, I will divide the article into these two points. This will make it much clearer and easier to understand this issue. What is our main goal? That's right, connect to Wi-Fi networks. You can do it! Follow the instructions.

Before you move on to any settings and bother yourself unnecessary information, try connecting your laptop to a Wi-Fi network right now. According to these instructions: . You may already have everything turned on, configured, and you will connect without any problems.

If something doesn’t work out, then watch this article to the end, or possible problems with the connection that I described in the article linked above.

Turn on Wi-Fi on a laptop: using a keyboard shortcut or a switch on the case

Almost every laptop: Asus, HP, Acer, Lenovo, Del, etc., has either a special switch or a keyboard shortcut that turns Wi-Fi off and on. Honestly, I don’t know how it is on other laptops, but on my Asus, pressing the FN+F2 key combination turns everything off wireless modules. The pop-up window says "all wireless device on". Which means everything wireless interfaces turned on or off. At the same time, Wi-Fi does not disappear.

These keys, or switches, should be checked only in extreme cases, when nothing else helps. And to manage wireless connections from under Windows. Since the combination special keys They don’t always work, or they work, but not as needed.

On the same Asus laptop, to turn off or turn on Wi-Fi you need to press the key combination FN+F2.

On laptops DEL, this is the key combination Fn+F2, or Fn+F12. On HP- Fn+F12. Lenovo- Fn+F5 (or, look for a special switch on the laptop case). If you have Samsung, then these are the Fn+F12 or Fn+F9 keys. And on Acer- Fn+F3.

As I already wrote, a special switch can also be used to turn on Wi-Fi. Look at the case of your laptop. And on the key that is used in combination with Fn, an antenna is usually drawn.

It is better not to touch these keys at all. As I wrote above, they do not always work adequately. And they are of little use. Everything is smooth, in most cases, pressing the keys simply tells the system to turn off Wi-Fi adapter.

Turn on Wi-Fi in Windows 7

Let's now figure out how to manage the wireless adapter in the operating system itself. Let's start with the most important thing. And most importantly, this is an installed, properly working driver for Wi-Fi (Wireless adapter). If there is no driver, then no matter how hard we try, we will not be able to turn on Wi-Fi. But first things first.

First, let's check if our adapter is enabled. To do this, right-click on the Internet connection icon (in the lower right corner), and select Network and Sharing Center. On the left, select Change adapter settings.

If near the connection "Wireless network connection" written "Disabled", then right-click on it and select Turn on.

After these steps, the Internet connection status should change. And if there are Wi-Fi networks available for connection within a radius, they will be displayed in a list that can be opened by clicking on the icon itself. You can select the desired network and connect to it.

If you do not have a “Wireless Network Connection” connection, then most likely you do not have the driver installed for the Wi-Fi adapter. Install the driver and everything will work.

How to check the operation of the Wi-Fi adapter in Device Manager?

You can also go to Device Manager and see if there is a wireless network adapter there and how it works. To open the device manager, do this: go to Start, then Control Panel. Select a section Equipment and sound. On the tab Devices and Printers click on device Manager.

In the manager, open the tab Network adapters. The Wi-Fi adapter has something like this: "Atheros AR9485WB-EG Wireless Network Adapter". You can navigate by word Wireless. You should have something like this:

If you see an arrow icon next to the driver, then right-click on the adapter itself and select Engage.

If the adapter is not in the device manager at all (usually there is only one driver network card) , then you need to install the driver. Again, you can look at the article.

That's all Wi-Fi settings in Windows 7.

After you finally connect to the wireless network, another surprise may await you - “No Internet access” error. I wrote about the solution to this problem in a separate article.
