Why the phone does not see the Wi-Fi network of the router. The laptop does not see the wireless network or local area

It is difficult for a modern person to imagine his life without the Internet, and even wireless. But it happens that the laptop does not see the wifi network, why this happens and what to do then, let's figure it out in detail!

Why the laptop does not see the wifi network: possible problems and their solutions

Let's go from the most probable to the most difficult - by way of exclusion. Let's get started.

The most common

So why the laptop does not see the wifi network - this can happen due to the fact that there is no wireless Internet at all!

1. Let's make sure that there is wireless Internet in the coverage area, for this, using other devices: a tablet, smartphone, laptop or PC, we will check if they see wifi on the laptop. If yes, follow on, if not, then he does not see wifi,.
   We found out that there is an Internet, but the laptop does not see the Wi-Fi network, why - it means that something is wrong with our device, as a rule, and there are extremely banal solutions.
2. See if the adapter is turned on, as a rule, the indicator on the keyboard is highlighted:

• off - looks like the screenshot below.
  
• turn on with the keys, according to the layout of the device, + from to.
• after that, the search for networks should begin with a notification in the tray and a yellow asterisk at the antenna, see the screenshot.
  
• if everything works and the laptop sees the Wi-Fi network - enjoy your surfing, otherwise further
• let's try to run troubleshooting - right-click on the antenna → "Troubleshooting"
  
  
  

• the procedure in most cases helps, otherwise we are looking for another reason why the laptop does not see wifi.

The driver is an important component!

We urge you not to forget that the driver is the link between the hardware and the OS. Without this talented negotiator, everything works quite crookedly or does not work at all - this may be the answer to the question - why the computer does not see the Wi-Fi network. Whether laptop or desktop, external or internal connection of the adapter, the solution is the same.

• In the taskbar, you can see another icon - a crossed-out monitor, see the screenshot.
  
  If Windows 7 or 8, follow:
• "Start" → right-click "Computer" → "Properties"
  
  
• " Device Manager"
  
  
• Expand "Network adapters"→ looking for "Intel (R) Centrino", "Atheros ..." are also possible, etc.
  
  
  It should be like on the screen, with the absence of any marks
• if there are red or yellow markings, right-click and select "Engage"- most likely a driver update will be required.

If Windows version 10, follow:

We see that the drivers are not installed:

• go to the manufacturer and load the appropriate drivers.
• install → system restart
• check if it works - we'll finish it, otherwise we are looking for other reasons.

We adapt - an adaptation!

There is such a word adapter - here it is that neither is the main opportunist, in the name of the appearance of internet, and if it is disabled - nothing will be seen!

Let's check if:

He sees everything, but not what is needed!

Why does the computer not see my Wi-Fi network, but catches everyone else - and it happens. Here it is already necessary to deal with the settings of the router. Let's take a look at the Asus models, and for the rest we will write them down with commands. First, connect to another existing Internet - for example, you can distribute it from your phone.

Now, on TP-Link equipment:

What's in a name…?

One involuntarily recalls the words of the classic A.S. Pushkin. Do not think that this is a joke, sometimes there is an SSID conflict, your computer does not see Wi-Fi, and everyone else does. Believe it or not, his change and Voila are enough!

Let's change it using the example of an Asus router with screenshots.

If you went to this page, then most likely your phone has stopped seeing the Wi-Fi network, or networks. This can be a home network, somewhere on a visit, a public wireless network, etc. The problem is that the network we need does not appear in the list of available ones on the phone. He simply does not find it, does not see it, and, accordingly, it is impossible to connect to such a network. It is not uncommon for a mobile device to fail to find a specific Wi-Fi network. Which, for example, a laptop sees and connects without problems. Or it may be that the phone does not find any network, but other devices see them and work perfectly with them.

In this article I will try to collect all the most popular causes and solutions that can help you solve this problem. As usual, first it is advisable to find out what the problem is: in a mobile phone, or a Wi-Fi router. If there is a problem with the Wi-Fi network at home, then we have a better chance of fixing everything, since we have access to the router itself. If this is someone else's network, then it is unlikely that you will be able to do something.

Basically, it doesn't make a lot of difference on which device you have the problem. It is clear that this is most likely an Android or iOS phone. Well, maybe also Windows Mobile. Since this problem can hardly be solved in the settings of the mobile device itself, it does not matter which device you have. Likewise with a router.

I have already written separate articles on Android and iOS devices:

The phone does not see the Wi-Fi router: possible reasons

1 Disable / enable Wi-Fi, restart your phone and router. To get started, just go to your phone's settings and turn off Wi-Fi. I think everyone knows how to do it.

Then turn it back on.

We reboot the phone:

• In Android, just press and hold the power button, then select "Restart". Depending on the manufacturer and Android version, the steps may be slightly different.
• On iPhone, hold and hold the Home and Power buttons. The phone will restart.

We reboot the router. If you have access to it. It is enough to turn off the power for a minute and turn on the router again. You can perform multiple reboots in a row. You can read in more detail.

2 We determine what is the reason.

Check all three points:

• If your phone does not see any Wi-Fi networks, but they do exist and other devices find them, then it is clear that the problem is specifically in your smartphone. All I can advise is to reboot it and remove the cover from it. If he is. If that doesn't work, you can try performing a full factory reset. If this does not help, then you will have to carry the device to the service center.
• When a device does not find one network, the first step is to check if other devices can see it. If they do not see it, then most likely the problem is on the side of the router. First, reload it. If that doesn't help, then see the article:.
• If other devices find a Wi-Fi network, but your phone does not, but at the same time sees other networks, then most likely the problem is in the router settings. Changing the wireless channel and region usually helps. Below I will discuss this in more detail.

3 Changing the router settings.

You need to go to the settings of your router, go to the section with Wi-Fi settings, and try to set the static channel of the wireless network and another region. You can also set the channel width to 20 MHz. Better to take turns.

On TP-Link routers, it looks like this:

More details in the article:. You can experiment with channel and region. For example, put the US region. If you have set a static channel in the settings, then set "Auto".

Other problems with detecting Wi-Fi networks

I also noticed that people often write that the phone does not see the Wi-Fi of the laptop. I understand that the problem occurs when distributing the Internet from a laptop or PC. In this case, my advice is to first make sure that the laptop is broadcasting a wireless network. For example, look from other devices. You may have started the access point incorrectly. This is where the article comes in handy. Bring your phone closer to your computer.

The next case when Wi-Fi problems appear after phone repair. For example, after replacing the battery, screen, glass, case, etc. In such cases, I advise you to immediately take the phone to the workshop where it was repaired. Since the master most likely did not connect the antenna, or the Wi-Fi module itself.

Well, there is no need to exclude hardware failure. Everything breaks down, and the module that is responsible for connecting to Wi-Fi is no exception.

As usual, you can leave your question in the comments, or share useful information on this topic. I am always glad to answer your questions and grateful for the additions to the article.

Wireless technologies are not standing still, and more and more routers are appearing on the market that can distribute Wi-Fi at frequencies 2.4 GHz and 5 GHz... Frequency 5 GHz has a number of advantages, among which, first of all, it should be noted less network congestion, support 23 channels against three in 2.4 GHz and higher throughput. Lack of frequency workers 5 GHz- smaller coverage area than networks 2.4 GHz.

Alas, not all computers and mobile devices can see such a network. Suppose you have a router that supports 5 GHz but your Windows 10 laptop does not detect the Wi-Fi. Is there anything you can do? Unfortunately, the wireless adapter of your device supports networks at a frequency 5 GHz is the main condition for working with them. However, there is a possibility that the adapter does support the frequency. 5 GHz, but incorrect parameters are set in its settings.

How to find out if the adapter supports 5 GHz

The first option is to go to the adapter manufacturer's website and familiarize yourself with its technical characteristics. But there is a simpler option. Open the command line as administrator and execute the following command:

netsh wlan show drivers

Among the list of parameters, we find and see what standards the adapter supports.

802.11b and 802.11g 2.4 GHz.
802.11ac- support for networks with a range only 5 GHz.
802.11a, 802.11n, 802.11j and 802.11n- can operate at a frequency like 2.4 GHz and on 5 GHz.

Note: it is necessary to distinguish adapters with the standard 802.11n Dual Band 2009 years and adapters 802.11n 2006 of the year, working only in one range.

If support is declared, but Wi-Fi- the network is not visible, in the device manager, in the properties of the wireless adapter driver, you must check the selected range. For example, in the case of the adapter Marvell AVASTAR Wireless-AC Network Controller in the tab "Additionally" you must select a property Band and set the value for it "Automatically" or "5 GHz only".

It is also worth considering the case when the networked 5 GHz the computer ceases to see it after upgrading to Windows 10. The main reason for this is replacing the adapter driver with a standard driver from Microsoft.

This problem is usually solved by downloading and installing the latest version. "Native" wireless adapter driver from the manufacturer's official website. At the same time, it is better to disable the automatic update of Windows drivers so that the driver is not replaced again with the next update. If the adapter does not support a higher frequency, but work in a network 5 GHz still want to, you can purchase an external USB Wi-Fi-adapter with appropriate characteristics.
