The computer does not see the asus router. What to do if the laptop does not see WiFi - causes and solutions

Hello! As I said, I work as a sys. admin in an Internet cafe, and naturally I understand with computer equipment and local networks.

So, recently my Aunt called me and asked me to come set up a D-link wi-fi router, which she had just bought in a store. I arrive, set up, everything is in order Aunt is happy Surfing the Internet on a netbook via Wi-Fi

But it was not there! The next day he calls and says the phone does not see wi fi and the laptop does not see wi fi! It finds only some neighboring access points and that’s it, well, I’m coming, I think let me check the router at home, I take it and go home, I connect Everything is ok, everything works! I'm shocked =) I come back to Aunt, I connect again, it doesn't work ... So I went to a friend, it also worked for him ... Then I started rummaging through the router settings, but could not find anything.

Then my Uncle comes into the room and says we have a security company from below, maybe their equipment is blocking? I think exactly! the problem is in it, you can’t see Aunt Wi-Fi And I’m leaving ...

But a few days later I got a call from 1 more person with an anthological problem! And I struggled for a long time to find a solution to this problem! In this article, I will now explain everything step by step how to solve such a problem!

Nowadays, a Wi-fi router has appeared in almost every apartment, and when you turn on the router in a neighboring apartment, you may lose Wi-fi Internet (everything will work fine through the cord in the computer).

Solution

I will show an example of a wi fi router router D-link DIR 300

The problem was that when configuring the router, the Wireles channel (Channel) is automatically selected by default (auto), shown in the screenshot:

We need to go to the router (web interface) if you did not change the local IP address when setting up the router, then you have it by default 192.168.0.1 , write this IP in the browser and go to the Web interface of the router.

We go to the item as on the screen and change the channel, set the number different from the one set automatically (I always got it the first time and everything started working).

Now the wi-fi network finds any of your devices!

Here is a simple solution to this problem
If you have any questions, maybe you have a different router firmware and you cannot find this setting, write in the comments, I will help you.

If you got a brand new laptop or your existing device stopped seeing available wireless networks, if after the next reboot or the next update of Windows and the driver your device stopped connecting to Wi-Fi, if you observe some difficulties when searching for a network or connecting to them, then this article is what you need. In it, we will analyze the most effective methods that will help eliminate the incorrect operation of equipment and explain why “the laptop does not see Wi-Fi” and “an error occurs when connecting to a Wi-Fi network.” Consider other issues related to the correct operation of Wi-Fi on a laptop.

You can solve the problem with detecting a Wi-Fi network yourself

Below we will provide detailed instructions for troubleshooting various problems. But the first thing to do to find out the reason why the laptop does not see the Wi-Fi network is to identify the source of the problem. Several components are responsible for the correct operation of the Internet connection and the Wi-Fi connection of your computer:

• A wireless router that is responsible for the direct creation and operation of the network.
• A network adapter built into a laptop that is responsible for receiving and processing the signal sent by the router.
• Drivers and software that ensure stable and correct operation of the network adapter.

If at least one of these components does not work as it should or does not work at all, the laptop will not see the Wi-Fi network or simply refuse to connect to it. Consider what needs to be done in order to identify the source of the problem. Knowing at what stage the snag occurs, you can proceed to troubleshoot and provide your computer with a quality Internet connection.

First of all, we recommend checking if Wi-Fi is activated in your laptop and whether it is ready to receive a signal. You can do this in various ways. The most obvious one is to find the wireless icon on the keyboard and activate the network adapter. The thing is that in most laptop models, to save battery power, Wi-Fi is quickly turned on and off. To do this, there is a button with the corresponding icon on the keyboard. On some models, this is the F2 or F3 key, which must be pressed at the same time as the Fn function button. And in some models, a special toggle switch can be built in, which is located on the side panel or at the top of the keyboard, separately from the main set of keys.

If a specific laptop model does not have a key to activate Wi-Fi, you can do this in the Windows Control Panel. To get started, follow this path: Start > Control Panel > Network and Internet > Network and Sharing Center. A new window will open in front of you, where you need to pay attention to the column on the left. Find the item "Change adapter settings" in it and click on it. You will see all the adapters and network connections that exist on your device.

Find “Wireless Network Connection” among them and see what is written right under its icon. If the status is "Disabled", then you need to right-click on the connection and click on the "Enable" item in the drop-down menu that opens. After that, go to the system tray in the lower right corner of the display. The icon of the active wireless adapter will be displayed there and by clicking on it, you can search for Wi-Fi sources.

Checking the router

The next step is to check the router. The easiest and most effective way to check the performance and correctness of the router settings is to connect another device to the target network, which will become an indicator of correct or incorrect operation. If another computer, tablet or smartphone connects to the Internet without any problems using the selected equipment, it will be quite easy to conclude that the router is working correctly, and the problem most likely lies in the laptop and its components. Software or hardware - we'll figure it out a little later. If the connection does not occur or the access point is also not visible on other devices, then it is worth re-configuring the router or diagnosing it.

There are times when a laptop sees available networks (neighboring offices, apartments, etc.), but your access point is simply not on this list. In this situation, we recommend that you search in close proximity to the router. This is necessary in cases where the device is new and recently configured. Perhaps its settings or location do not allow it to broadcast a signal to the required distance, while in close proximity it can work flawlessly. In the event that the laptop sees the desired network in close proximity to the router, you will need to check the settings of the latter.

Checking and installing the driver

What to do if all the previous steps were completed, but the laptop did not see the available Wi-Fi sources, we will consider in this section. In the case when the network adapter driver is not installed, does not work or does not work correctly, you can see the corresponding icon in the system tray - the monitor and cable icon crossed out with a red cross. In this case, do the following:

• open the properties of your computer by right-clicking on the corresponding icon on the desktop;
• a new window will open in front of you, in the left column of which you can find "Device Manager". Run it;

Among the "Unknown devices" may be the required network adapter

• in a large list with nested items and a large number of categories, find Network adapters;
• since there are usually several of these same adapters in your PC (wired and wireless), find the wireless one among them. Most often, it is listed as Wireless Network Adapter or a derivative of a similar phrase;
• click on this line (you also need to do this with the right mouse button) and in the drop-down list that appears, select the very last item - “Properties”;
• you will see the system properties window of the adapter. Check it for the status indicated in the “Device Status” item. If the status differs from "The device is working normally", this indicates the incorrect operation of the driver or its complete absence. This happens after a system reset. In this case, you will need to visit the official website of the manufacturer and download the driver for the Wireless Network Adapter designed specifically for your model on the support page.

After installing the wireless adapter driver, you must restart your computer. After turning on the computer, go to the "Control Panel" again and check the status of the device again by opening its properties. Now the status should sound like "The device is working properly" - this means that you can start searching for available networks and connecting.

Fallback

A situation may arise when you carefully followed all the steps mentioned, made sure that the settings were correct or did it again from scratch, the performance of all important components, it would seem, is beyond doubt, but the laptop still does not see even the nearest Wi-Fi networks. We recommend visiting a service center for a complete and professional diagnostics of devices. This is necessary to diagnose the router in the event that not a single device could detect a wireless network signal, but you are sure that the settings are correct. Or for a full laptop test - in the case when all drivers are installed and updated, but the network adapter still does not see a single Wi-Fi network or the system even reports errors and incorrect operation of network equipment.

We will explain why the laptop does not see Wi-Fi and how to solve the problem we will explain in the article, since no one is immune from malfunctions of the wireless Internet connection. The WiFi connection may not be functional for a number of reasons. And it is not necessary that these reasons will be somehow connected with each other.

You can easily check why the laptop does not see the Wi-Fi network. To do this, we first check the access point or router, as well as the laptop itself for performance. It is important to know which device is causing the problem.

Let's start with the router. Quite a common cause of a malfunction is the banal “freezing” of equipment. The first sign of this is an atypical indication, that is, the LEDs on the router are blinking in an unusual mode. To correct the situation, restart the device or unplug it, wait a couple of minutes, and then turn it on again. If it's a minor internal glitch, restarting solves the problem. The laptop, in turn, will quickly pick up the signal.

Voltage fluctuations can cause parameter reset. The router stops signaling. In some cases, the Internet connection is also lost. If this happens, then the settings must be re-entered using the device web interface. Input addresses: 192.168.1.1 or 192.168.0.1. The choice will depend on the model of the router. You can access the interface from any browser. If after that the connection worked, then everything is in order with the device.

Helpful advice: The reason for the incapacity of the router is often the involuntary reset of the router to the original settings. To set up the configuration again, it is better to use the services of specialists from the provider company.

If each of the ways to check the router did not work, you need to check why the laptop does not see Wi-Fi. First of all, we check the activity of the network equipment. On the case of most models of modern laptops there are LEDs. We will be interested in the one that is marked with an antenna icon or directly with the inscription "Wi-Fi". If the diode is lit, then the built-in adapter is functioning. Otherwise, the adapter must be started. We hold down the "Fn" key and another one, where there is an antenna icon.

The cause of temporary inoperability may be a malfunction of the operating system software. Connection activity will be checked through the Windows Control Panel. If it does not work, then the launch is carried out using the context menu.

The NE may not be listed at all in the list of available connections. We check the "Network Adapters" section, and more specifically, the "Wireless" wireless devices. Enable the adapter using the context menu. Then we restart the computer.

Why does the laptop not see wifi? Typical Causes

There are several simple reasons why the laptop does not see Wi-Fi. For example:

1. The router is not turned on - turn on the router;
2. No Wi-Fi coverage – get closer to the source;
3. Your router is "buggy" - reboot it;
4. W-Fi receiver is not turned on - turn it on.

However, there are more serious violations of the connection. These include:

Wi-Fi is slow, why?

In addition to the fact that the computer does not see "wi-fi", the problem of a slow connection is also relevant. There are several reasons:

It would seem that it could be easier than connecting a router to a computer? It's only a matter of a couple of minutes. But sometimes the result can be completely unexpected, for example, the computer does not see the router, and it is impossible to enter the router settings. What to do in such a situation? For those who want to try to fix the problem on their own, here are some simple tips. But first, a few words about the possible causes of the failure.

Why the computer does not see the router: possible reasons

As for the reasons, there can be quite a lot of them, from a banal incorrect connection to equipment malfunctions, including the router itself and the corresponding ports on the computer (physical breakdowns or software failures of the device itself will not be considered in detail).

However, the main prerequisites for the computer not seeing the WiFi router, depending on the situation, are the following:

• incorrect connection;
• incorrect access parameters;
• lack of network card drivers;
• inoperability of the Wi-Fi module;
• hidden network.

What to do if the computer does not see the router with a direct connection?

Let's start with a situation where the user is trying to connect to the router for initial setup via cable directly. It seems that all the cables are connected correctly, but still there is no connection. Well, the computer does not see the router, even if you crack. What to do?

First of all, if you are sure that all cables are connected correctly, check if the address of the router itself is entered correctly in the web browser. In most cases this is 192.168 with the last two digits being 0.1 or 1.1 (other addresses may apply for some non-standard models).

The login address can be found on a special plate, which is located on the back of the device. There is also a username and password that must be entered when entering the settings.

If everything is entered correctly, but the router is not visible, the usual reboot of the router by pressing the On / Off or Power buttons for 10-15 seconds may help. However, it is best to completely disconnect the router from the mains, maintaining the same interval. If after that the computer does not see the router, you can try to reset the router settings to factory settings. To do this, there is a small hole in the bottom of the case, in which there is a barely noticeable Reset button.

Checking the correct connection

If the previous actions did not have an effect, you should check the correctness of the direct connection.

Try plugging the network cable into a different connector on the router or doing the same on the computer's network card. If that doesn't work, the cable itself might be damaged. In this case, just replace it and try to enter the settings again.

Connectivity Diagnostics and Ethernet Port Testing

Also, the situation when the computer does not see the Wi-Fi router may be due to a breakdown of the ports themselves. As already mentioned, use a different port or “ring out” the one to which you are connecting.

However, the reason may also be in the network adapter. In this case, you should make sure that all the necessary drivers are installed for it in the system (and correctly). If the device is marked with a yellow icon with an exclamation point in the appropriate manager, the drivers need to be reinstalled. Also, as an option, you can use the complete removal of the device, followed by a system reboot when the driver is installed automatically. In the case of non-standard equipment, you must use the original discs or specify the location of the driver installation file on the hard drive manually.

For more information, you need to run a connection diagnostic. It is performed from the adapter settings section, which is located in the network connections menu located in the standard Control Panel. If problems are found, the system will report on their elimination.

Checking network attributes

Finally, the reason that the computer does not see the router when using a wireless connection may be the network hiding set in the settings.

In this situation, you need to connect directly to the router via a cable, enter the wireless settings and uncheck the SSID broadcast enable line (for TP-Link models). In other devices, this may be the option to hide the network name, set to simply hide the network (SSID), or something like that. After that, it is desirable to reboot the device in the manner described above. In addition, it would be nice to restart the main computer system (as they say, you never know).

Conclusion

In most cases, these methods help to fix the connection situation. If none of these solutions helped, in order not to replace the equipment, you will need to flash the device. Doing it yourself at home is quite problematic, so it's best to contact some service center. If such actions do not give any result, you will have to make a complete diagnosis of the router not for the presence of malfunctions, but if they are detected, replace the device.

But, as practice shows, most often there are incorrect input of addresses and parameters when entering the settings, cable and port breakdowns, lack of drivers for network cards and wireless modules, as well as set parameters for hiding networks. So at least one of the proposed methods, but will help.
