Does not define WiFi. Why the phone does not see the Wi-Fi network of the router. The case when the laptop does not see a specific network

Hello everyone! As I said, I work SIS. admin in the Internet cafe, and naturally understand computer equipment and local networks.

So, I recently called my aunt and asked to come to customize Wi Fi d-LINK routerwhich she just bought in the store. I come, set up, everything is in order of aunt satisfied Surfit Internet on a netbook on Wiifa

But it was not there! The next day calls, and says the phone does not see Wi Fi and the laptop does not see Wi Fi! Only a neighbor some kind of access points and everything, well, I come, I think I will check the router at home, I pick it up and I will break home, I connect all the ok everything works! I'm in shock \u003d) I come back to aunt I connect again not working ... So I traveled to a friend, I also worked ... I began to rummage in the router settings, but I could not find anything.

Here my uncle comes into the room and he says from us from below a security company can their equipment blocks? I think for sure! The problem is in it, not see you to aunt Waifai and leaving ...

But after a few days another 1 person called me with an anthole problem! And for a long time I trickly found a solution to this problem! In this article, I will explain everything on the steps now how to solve such a problem!

Nowadays Wi-Fi Router It appeared in almost every apartment, and when you turn on the router in the next apartment you can have the abyss of the Internet on Wi-Fi (through the cord in the computer everything will work fine).

Solution to the problem

Show on the example Wi Fi router Router D-Link Dir 300

The problem was that when setting up the Wireles Channel router (channel), the default automatically (AUTO) is shown, shown on the screen:

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

We go to the item as on the screen and change the channel, we set the number other than the installed automatically (I always hit the first time and everything started to work).

Now the Wi Fi network finds any of your device!

Here is such a simple solution to this problem.
If you have questions, you can have another firmware of the router and you can not find this settingWrite in the comments, I will help you.

The problem of incorrect display or complete absence available WiFi Networks occur quite often and affects not only laptops, but also stationary computers, tablets, smartphones, etc.

Possible reasons for the fact that the Internet does not work on a laptop through wif enough. To properly choose the solution to this problem, you need to evaluate how exactly the "scenario" belongs to your situation: the laptop has stopped seeing wiFi network (i.e., the full "ignore" wireless connections) or the laptop does not see WiFi from some single access point, without difficulty, defining other sources of Wi Fi.

Why wifi does not work on a laptop?

To begin with, it is necessary to disassemble the most common scenario - complete "ignoring" with a computer of all wireless networks. Those. Are you sure that:

• - the router normally distributes the signal and the access point is "open" to connect;
• - Nearby there are other available WiFi networks;
• - other devices (for example, cellular telephone) The active sources of the wireless signal determine without any problems.

But at the same time, your laptop does not find any WiFi network and does not connect to the Internet - i.e. In general, Wai Fi on a laptop has stopped working.

1. 1. To solve this problem, first of all it is worth checking if the "Wireless Adapter" is included in general. For this:

• - Open the Device Manager, in the "Device Tree" select "Network Adapters";
• - in the list that opens, the adapter of your wireless network must be (whose name depends on the device model and clarify this parameter in the documentation for the laptop);

• - near the name of the adapter should not be a triangular yellow icon with exclamation familiar - It means that the wireless network adapter is disabled, or installed and used by the laptop network Driver it works incorrectly;
• - To press it with the right mouse button and click "Enable / Connect";
• - If the driver incorrectly works - download and install actual version Programs for your laptop. Or delete the device via "Device Manager" (first download necessary driver - For the safety net) and restart the PC - the adapter must appear automatically.

In addition, you can check the adapter through the "Control Panel" - "Network Management Center and common access": If the adapter is enabled, there must be a section or" wireless network adapter "or" wireless adapter ".

1. 2. It is possible that the laptop does not see Wai Fi due to the fact that the network is disabled by a combination of keys or a special switch on the housing: for laptop owners this reason most relevant.

It is worth paying attention to the keyboard key "Fn + F2" / "Fn + F3" / "Fn + F9" / "Fn + F12" (depending on the laptop model) - this combination includes / disables the network and is intended mainly for those Who often makes airfares (respectively, such a regime is called "in the aircraft" - a similar function has a majority of modern smartphones and tablets).

1. 3. If the laptop stopped seeing WiFi after the device was disassembly (for cleaning up the upgrade dust), then, possibly, a wireless module was physically disabled during the parsing or the integrity of the connection wires was physically disabled. In this case, the solution to the problem, respectively, will be the connection of the adapter (and in the case of a physical malfunction - replacing it onto a working module).

Why doesn't the laptop sees WiFi, and other router devices see?

Now consider the situation when the laptop selectively sees the "WiFi" network. It is worth noting that most of the problems with wireless networks can be resolved by updating network drivers.

So, there is a certain network that works and is displayed on other devices, but the laptop with great perseverance does not want to see it. You can make the following:

This concerns the computer directly, but the culprit that the laptop does not see Wai Fi router, the wireless signal itself can be.

• - Check the relevance installed firmware On the router: if the firmware is outdated, then, respectively, update it to the most "fresh" version;
• - Reset the router configuration to the default value (factory settings) and re-configure the router;
• - In some cases, it helps install an older version of the firmware, with setting the network configuration and followed by updating the firmware.

Thus, the most relevant and effective solution of the problem "Laptop is not looking for Wi Fi" is to check the performance of WiFi module and installing current drivers.

In order to avoid such a problem, it is regularly (manually or using special programs).

Wireless Internet connection has many advantages, but often the situation is found when the laptop does not see Wi-Fi Network. To start solving the problem, you first need to figure out what exactly happens. Sometimes the laptop "refuses" to see some specific point of connection, in other cases the device can not connect any wireless network at all.

Why the laptop does not see the network

The most often occurs the situation when a laptop does not find any point at all access Wi-Fi. At the same time, conditions are carried out:

• home Wi Fi Router works fine, and to the access point is allowed
• you tested a laptop and in other places where there are wireless Internet, for example, in a cafe
• phone, tablet or other devices are normally connected to Wi-Fi

To understand why this happens, and cope with the problem, you first need to try to manually turn on the network adapter. Depending on the operating systemThis is done in the following ways.

For Windows 7, the sequence looks like this:

1. You need to go to the control panel and select the Network Management Center item, and in it - change the adapter parameters.
2. If the wireless network icon is inactive, you need to click on it right key Mouse and turn on.

If you have on windows Computer 8, then the activity check is done through the PC settings section, which is in the control panel. It needs to choose item Wireless connection And move the slider to the position "Included".

In Windows XP, the adapter is usually not required manually. If it is still needed, then it is done in the same way as in Windows 7 or through the icon on the taskbar.

The same can be done through the Device Manager - network adapters.

Whatever Operations, if a yellow triangle with an exclamation mark is glowed next to the adapter icon, it means that either the adapter is not active or the driver is not installed for it. If the device does not indicate the connection due to the driver, then you should download the desired versionsuitable for your laptop.

The network is disabled by hardware

Access to the network can be disconnected on the laptop itself using a key combination or a special switch on the housing. How to make the device connected to the Internet? It is necessary to press the same combination again.

For different models Laptops This action is made using different combinations Keys: "Fn + F2", "Fn + F12", "Fn + F3", "Fn + F9". These combinations help disable the network, for example, in front of the flight - this option is called "on an airplane" and is available on all modern mobile devices.

After cleaning there is no network

Also, sometimes you may find that the laptop stopped seeing the Internet after it was brushed from dust inside. If this happened, it is likely that during the cleaning process, you accidentally disconnected the wireless module or separated the wires somewhere. At the same time, the laptop does not even look for the network. To eliminate the problem, you will need to connect the adapter again, and if it does not help - replace it with a new one.

All devices, except laptop, see Wi-Fi

Now consider another case, namely - when there is one point access WiFi.that the phone, netbook and other devices see, and the laptop does not catch it. In such a situation, the sequence of actions looks like this:

• First try to change the encryption method, going to WiFi security settings
• Try installed different values In the "Channel" paragraph, perhaps after that, the computer will connect to the network
• You can also give the network a new name, avoiding too complex combinations of characters.

Another common reason that the device ignores a certain network or does not see the access points at all, including Windows 10, may be presence in the viral software system. In this case, it is necessary to scan the PC for the presence of viruses and delete them.

Mallings with router

"The culprit" that PC does not find a network, maybe himself wiFi router. What to do in this case?

1. First, you should find out if fresh firmware is installed on the router. If already came out a new version, Accordingly, it must be installed on the device.
2. More radical option - reset the settings of the home of the router to the factory settings and adjust the device again
3. Sometimes it has to act more cunning. First set more old version Firmware, then all settings of the network are configured, after which the firmware is updated.

Whatever problem has led to the fact that the laptop does not see wireless networkIt can be solved by any of the listed ways. At first, in any case, it is worth installing topical drivers and check whether the WiFi module is functioning normally.

Video - What to do in this situation?

So that in the future such problems did not return, it is necessary to periodically install fresh versions software On your laptop or netbook. This can be done both manually and using special programs.

It would seem that it may be easier to connect the router to a computer? This is just 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 in the settings of the router parameters. What to do in such a situation? Those who want to try to eliminate the problem on their own, then there are several non-good tips. But first a few words about possible reasons Failure.

Why does the computer sees the router: possible causes

As for the reasons, there may 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 that the computer does not see a wifi router, depending on the situation, are considered as follows:

• incorrect connection;
• incorrect access parameters;
• no network card drivers;
• inoperability of the Wi-Fi module;
• hidden network.

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

Let's start with the situation when the user tries to connect to the router for implementation initial setting Through the cable directly. It seems that all cables are connected correctly, but no connection is not connected. Well, does not see the computer router, even though you are crazy. What to do?

First of all, if you are exactly 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, it is 192.168 with two last digits 0.1 or 1.1 (other addresses can be used for some non-standard models).

The input address can be found on a special plate, which is located on the back of the device. There is also a login and password that you want to enter when entering into the settings.

If everything is entered correctly, but the router is not visible, it may help usually restart the router using the ON / OFF or POWER buttons by 10-15 seconds. However, it is best to turn off the router completely from the power grid, withstanding 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, in the bottom of the case there is a small hole in which the removable reset button is located.

Checking the correct connection

If the previous effects have not occurred, it is necessary to check the correctness of the direct connection.

Try insert network cable In another connector on the router or produce similar actions On the computer's network card. If it does not work, perhaps the reason is damaged by the cable itself. In this case, simply replace it and re-try to enter the settings.

Connection Diagnostics and Verification of Ethernet Ports

Also, the situation when the computer does not see the Wi-Fi-Router may be associated with the breakdown of the ports themselves. As already mentioned, use another port or "ring" the one to which connection is made.

However, the reason may also be in network adapter. In this case, you should make sure that everything is installed in the system required drivers (And correctly). If the device in the corresponding dispatcher is marked with a yellow icon with an exclamation mark, the drivers must be reinstalled. Also, as an option, you can use full removal Devices with a subsequent restart of the system when the driver is installed automatically. In the case of non-standard equipment, you must use original discs or specify location installation File Drivers on a hard disk manually.

For more more detailed information It is necessary to diagnose the connection. It is executed from the section of the adapter parameters, which is in the menu network connectionslocated in the standard "control panel". If malfunctions are detected, the system will report them to eliminate them.

Checking network attributes

Finally, the reason that the computer does not see the router when used wireless connectioncan be installed in the network hiding settings.

In this situation, you must connect to the router directly by means of a cable, enter the wireless mode settings and uncheck the SSID broadcast line check box (for TP-Link models). In other devices, this may be the network name of the network name, the installation is simply hiding the network (SSID) or something else in this way. After that, the device is desirable to restart the method described above. In addition, it would be nice to produce and restart the main computer system (as they say, you never know what).

Conclusion

In most cases, the methods presented help to correct the situation with the connection. If none of these solutions helped not replace the equipment, it will be necessary to rotate the device. Do it yourself at home is quite problematic, so it's best to contact some service center. But if such actions will not give the result, you will have to produce full diagnostics Router is not an object of faults, and when revealed to replace the device.

But, as practice shows, the incorrect entry of addresses and parameters occurs when entering the settings, breakdowns of cables and ports, no drivers network cards and wireless modules, as well as installed network hiding parameters. So at least one of the proposed techniques, but will help.

When using multiple computers in one local network It happens that one car for some reason does not see the other. As part of this article, we will talk about the causes of such a problem and the methods of its decision.

Before switching to the main reasons, you need to check in advance whether all PCs are rightly connected to the network. Also, computers must be in an active condition, since sleep or hibernation mode can affect detection.

Note: Most problems with the visibility of the PC on the network occurs according to the same reasons, regardless of set version Windows.

Cause 1: Working Group

Sometimes PC connected to one network have a different workgroup, because of which I can not be detected by another. Decide this problem Pretty easily.

If you are all done correctly, difficulties with detection must be resolved. Generally similar problem It becomes infrequent, since the name of the working group is usually set automatically.

Cause 2: Network Detection

If there are several computers on your network, but none of them is displayed, it is possible that access to folders and files has been blocked.

The changes must be applied on all PCs on the local network, and not only the main one.

Cause 3: Network Services

In some cases, especially if you are using Windows 8, an important system service can be deactivated. Her launch should not cause difficulties.

After that, you need to restart the computer and check the visibility of another PC on the local network.

Cause 4: Firewall

Literally any computer is protected by antivirus, allowing to work on the Internet without a threat to infection with viruses. However, sometimes the protection means is the cause of blocking full of friendly connections, which is why it must be temporarily disabled.

When using third-party antivirus softwareYou will also need to disconnect the built-in firewall.

Additionally, check the availability of a computer using command line. However, find out before this, find out the IP address of the second PC.

In case computers do not ping, check the firewall again and proper setting Systems in accordance with previous paragraphs of the article.

Conclusion

Each solution voiced will allow you to make computers without any problems visible within one local network. In case of additional questions, contact us in the comments.
