Unfortunately, many of us are faced with the problem, when the laptop stops to find a wireless network that creates a tangible inconvenience. Given that the laptop may be used outside the home, the user can go without the Internet altogether. The reasons for this are not pleasant the moment might be too much. But, as a rule, the problem is technical, or in incorrect operation of the software. To understand how to deal with the problem, analyze it in more detail.
In order to understand the cause of the problem and understand why the laptop can not find WiFi router or home WiFi network, you need to know what is Wi-Fi and to understand how this wireless system works.
Wi-Fi is a local network, but without the hassle of cabling. The connection to the network occurs via a signal transmitted via radio waves. This system has gained popularity not so long ago. A dozen years ago about her no one knew, and the distance of the signal was considerably less. To be precise, the signal can be sent at a distance equal to 100 km.
In addition, Wi-Fi is a registered mark, which is very actively developed. In 2014, the speed of data transfer via Wi-Fi needs to grow to several GB/s.
Simply put, now this method of network connection is very popular. Almost every laptop has a built-in sensor, which allows you to use your wireless network. At bus stops, in cafés or any other public places, the owners installed a free access point that increases the level of comfort of the institution or public places.
The main reasons for the lack Wi-Fi
As mentioned above, the main causes can be divided into technical and software. In the case of technical, the owner of the laptop will probably have to go to service center and spend money on its repair. In the best case, to deal with the cause of the poor performance of the router.
The presence of WiFi on the laptop and the router
You should start with the basics, which you can forget because of haste or carelessness.
You must ensure that the receiving antenna is in the enabled state. If the button does not work WiFi, then the problem is obvious. Not all models of the laptop this switch is present, but for some it still is. Looks, often not in the form of a button and a latch. In other matters, it depends on the manufacturer. With the switch could be a signature or image antenna, which means Wi-Fi.
If the button on the laptop model is not, it is necessary to pay attention to the bottom panel of the operating system, the icon next to the time. The image must be visible, active wireless connection at the moment.
It is possible that the icons on the toolbar next to no time.
To test the activity without the help of this icon should be:
- go to «control Panel – the control Center network and sharing – Change adapter settings»;
- right-click the mouse on the wireless connection and click on the line «include». Accordingly, after these steps, the connection will become active.
Check for available networks
Next, you need to do is to check the available network. Maybe the router just doesn’t reach the antenna of the laptop and for this reason to the network cannot connect.
To do this:
- click on the network icon in the lower right corner, on the bottom, next to the time.
- to select the item «connect to network» and choose the desired access point. Most likely, the access point would not be one, as you can see the neighbor’s or any of the other routers. But, in most cases, the access point put the password, protecting thus from unauthorized users.

The laptop does not see Wi-Fi network: the main causes
Why the laptop does not see the WiFi network? Perhaps the solution is right in front of you and takes only five seconds of time. But there are more severe cases. Consider the most common options.
You should make sure the router is turned on. His work can be easily identified by lights. After connecting, view the relevant icons in the user to the router and determine whether the active wireless connection.
If the router does not respond, then the problem is purely technical. In this situation, you should look for a problem in the wires, the power supply or the router to carry in repair. Typically, the router is easier to replace with new than to give it to service centers for inspection.
As you know, any hardware requires software, which ensures stable operation. If the laptop does not detect WiFi, you should check the driver. Even if they are installed, it is recommended to update them.
The test drivers can be done via the control panel. Under «device Manager» there is a line «network adapters» which should be the name of the router, if the problem is in the drivers. Just right click on it and view the driver version. Compare it with this version, which you can find on the Internet.
If the version is outdated, then download new and install. It is best to download from official sources. Driver for equipment distributed by developers for free, and it is not necessary for in vain to risk the «health» of your operating system.
The distance signal
In case after searching an answer: «No available connections» — think about the signal. In apartments this option is not very relevant, since modern routers have a strong signal and distribute it far enough. But in private homes or other places where the distance can be quite large, the signal just can’t reach the laptop. So do not be surprised if the Internet suddenly disappeared, when you walked around the house or yard.
There are situations when it can connect, but the router does not see Internet through my WiFi or stopped to see. When using the services of some providers, the user can not just change the network adapter because it changes the Mac address.
The Mac address is written on every router and user just need to call the operator to a new address to tie in with the old. You may be asked to dictate it completely, or to specify only the last few values of the entire room.
Antivirus or third-party programs
Third-party programs installed on the laptop may interfere with the driver or interfere with properly install the Internet connection that often happens when the device sees wifi but does not connect. In addition, sometimes anti-virus software interfere with the new connection. If possible, it is better to try first to connect to the Internet without a router. If all is well, then do not blame the program.
In addition to these, the reasons can be a lot. Basically, a variety of reasons develops because of problems with the operating system. So if nothing helps, try reinstalling your operating system. Perhaps all the problems go away.

For comfortable use of the network some users have resorted to the settings. Usually enough of the standard settings, but if you wish, you can delve into your personal account. It is through personal study by changing parameters.

All other settings are made on the laptop, and they are using the network and sharing center.
WiFi without Internet because of Windows
There are rare cases when the operating system itself will not identify the wireless connection and shows that the external network is not at all. This may be when using not license the OS. Some prefer to use Amateur assemblies, which are not taxing the system and allow more to squeeze out of iron.
Another reason could be «blockage» of the system. System folder, over time, become clogged with unnecessary files and if not to defragment, then the processor will load more and more. Anti-virus software can’t always keep the laptop clean.
In any case, all problems are solved with a simple OS reinstall. After reinstalling Windowsвсе should work.
