Why can't I connect to another WiFi. Laptop sees Wi-Fi but not connected? Let's fix it quickly

The Internet and the latest electronic technologies are very closely in our lives. And sometimes problems with access to the Internet can cross all our plans and prevent our work or rest. The phone not only helps to be in touch, but also opens the door from anywhere in the world web, on the Internet. At the same time, no one is insured against sudden problems, then the question arises: why the phone does not connect to WiFi Router? This information Also refers to those users who do not know why the tablet does not connect to WiFi.

Consider typical reasons below. I must immediately say that the solution can "walk" in simple manipulations with the phone. Therefore, apply the described methods below without thinking that it will not help in your situation.

What could be the causes of broaching WiFi in the phone or tablet

First you need to restart the phone and turn off / enable Wi-Fi network on your phone. Then restart the router (router). If there are still no network, it means that it is in the other. It can also help - pull out the battery and connect again, after that restart the phone.

The reasons for the resulting problem may have incorrect network security settings or router, as well as channel operation mode. What errors most often can we observe on your device?

• In the connection status, we see: "Getting an IP address ...", or just "connection ...". But the phone does not connect to the network. That is, you specify the network where you want to connect, and the phone cannot do this.
• The problem of authentication (authentication error), or simply the status "Authentication ...". In this case, the "Disabled" appears in this case, and the phone to Wi-Fi is not connected.
• The inscription in the device "Saved, WPA \\ WPA2 protection".
• The phone to the Wi-Fi router is connected, but the Internet does not work, and sites do not open in the browser.

What solutions can be that the phone or tablet connects to WiFi

So, possible solutions to your problem.

Deleting WiFi compound

The first thing I could advise you is to remove the connection that has been preserved in your phone. To do this, select the network through which the Internet came and click on "Delete" or "Delete this Network". Below in the screenshot can see how it looks like:

After that, try to connect to this network again.

Reloading router

Sometimes with the problem of connecting not only the phone, but also other devices you just need to restart the router. A small note: You should not just pull out and connect the socket across a second, and turn off the router power cable for 10 seconds and already connect it again.

You have to wait a while so that there is no energy left in the router. Such a scheme is often needed with other devices that feed on energy. By the way, you can use the button that is on the router itself by the same procedure that described above.

Change the channel in the router

If you have not changed any settings and the connection with your router has always been without any problems, then you should try to change the Wireless channel channel (wireless network). It happens very rarely, but there is a little percentage that this setting You can help.

Where can I change the channel for your Wi-Fi? To do this, go to the configuration of your router into the "Wireless Network" tab and change the channel (Channel), then save the settings, restart the router and try to connect. If it does not work the first time, the same scheme repeat with other channels.

Check the password that enter when connected to WiFi

If the authentication error is displayed on your phone, the problem may be in an incorrect password or in incorrectly specified security settings.

First of all, you need to check the correct password correctly. How to do this, because the request for the password can not appear for some users? You need to delete your connection and re-enter the password by clicking on your network. When entering the password, always be attentive. If you forgot your password, you can see it in the router settings.

Here are the articles that will help you in this procedure:

If it is not a password, then you need to check the security settings. To do this, set the security type WPA2. Password need to specify more than 8 characters and can try use only numbers.

Saved, WPA \\ WPA2 protection and password change in router

One of the most common problems when the inscription "Saved, WPA \\ WPA2" is displayed on the phone, and the connection icon can show the availability of connection, and there is no Internet in the device.

If the options described do not help, then you need to check in the router settings / Wireless speed (wireless network), as the phone does not always support the mode of operation of the router. To do this, you need to install automatic or mixed network mode instead of b, g or n.

If it did not work out to correct the problem and you still have a dilemma, why the phone does not connect to WiFi, try changing the type of encryption / security, which I have already mentioned:

• WPA / WPA2.
• WPA-PSK.

These settings are indicated in my router:

Password (key) Enter a new one of 8 characters and more. It is advisable to change the password, since you may have forgotten the password and enter non-existent.

Next - the whole same scheme: save the settings, restart the router, delete the connection on the phone and connect by entering the new password when prompted. It should be remembered that the new password will be needed to specify in other devices that use this router. For example, if you have a laptop home or computer, then you need to reconnect to WiFi by entering a new password that you indicated in the router.

Channel width

Change the channel width in the router settings (Channel Width). Typically there are several options: AUTO, 20MHz and 40MHz. After changing, save and restart the router.

If there are other options, then try to use them.

Mac Filter and IP Addresses

Make sure the Mac or IP addresses is disabled. If in the router you activated this function and did not specify which Mac and IP addresses can be connected to routers, the problem may be in this setting of the router.

Here are the most common moments, why the tablet or the phone does not connect to WiFi. I hope that one of my tips will help you.

By the way, if you have a problem with WiFi yourself, check out the article "":

Here is an example when the user could not connect to WiFi C iPad:

So, it would seem that a laptop (netbook, etc.) with a Wi-Fi network and no questions work. And in one day you turn it on - and an error crashes: "Windows failed to connect to Wi-Fi ...". What to do?

So actually it was with my home laptop. In this article I want to tell how to eliminate this error (besides, as practice shows, this error Pretty common).

The most common causes:

1. Lack of drivers.

2. The settings of the router (or changed) were shot.

3. Antivirus programs and firewalls.

4. Conflict programs and drivers.

And now about how to eliminate them.

Troubleshooting "Windows failed to connect to the Wi-Fi network"

1) Setting up Windows OS (on the example of Windows 7, in Windows 8 - similarly).

If the error still takes out that it is not possible to connect to the network (as in the picture below), click on the button " troubleshooting"(I know that many are very skeptical about it (he himself also treated until she helped restore the network a couple of times)).

If the diagnosis did not help, go to " Network Management Center and common access "(To go to this section, simply right-click on the network icon next to the clock).

Now simply delete our wireless network to which Windows cannot connect to anyone (by the way, the name of the network will have its own, in my case it is "autoto").

We try to connect to the Wi-Fi network that in the previous step we deleted.

In my case, Windows was able to connect to the network, and without unnecessary questions. The reason was banal: one "comrade" changed the password in the router settings, and in Windows in the settings of the network connection, the old password was saved ...

2) Setting the Wi-Fi network in the router

After checking the wireless connection settings in Windows, the second you want to do is check the router settings. In 50% of cases, they are to blame: either they moved (which could happen, for example, when the electricity is turned off), or someone changed them ...

Because From the laptop to the Wi-Fi network you could not, then configure Wi-Fi connection It is necessary from a computer that is connected to the router using a cable (twisted pair).

In order not to repeat, this is a good article about. If you can't enter, I recommend to get acquainted with this:

In the router settings We are interested in the "Wireless" section (if in Russian is the setting of Wi-Fi parameters).

For example, in tP-LINK routers This section looks like this:

Configure TP-LINK router.

By statIn some cases, it may be necessary to reset the router (router). There is on his package special button for this. Hold it and hold 10-15 seconds.

Task: change the password and try to configure the wireless connection to Windows (see paragraph 1 of this article).

3) Driver Update

The lack of drivers (however, the installation of drivers that do not suit the equipment) can cause and much more serious errors and failures. Therefore, after checking the settings of the router and network connection in Windows - you need to check the drivers on the network adapter.

How to do it?

4) setting up the autoload and disable antiviruses

Antiviruses and firewalls (with certain settings) can block all network connections, allegedly protecting you from dangerous threats. Therefore, the easiest option is to simply disable them or delete them.

Regarding autoload: At the time setting, it is also desirable to remove all programs that are automatically downloaded with Windows. To do this, press the "Win + R" buttons (valid in Windows 7/8).

Then enter the command to "open": msconfig

5) If nothing helps ...

If Windows is still can't connect to Wi-Fi, you can try to open command line and enter the following commands sequentially (enter the first command - press ENTER, then second and again ENTER, etc.):

route -f.
Ipconfig / Flushdns.
Netsh int ip reset
Netsh int ipv4 reset
Netsh int TCP Reset
Netsh Winsock Reset.

Thus, we reset the settings of the network adapter, routes, clean the DNS and WINSOCK. After that, you need to restart the computer and configure the network connection settings.

If you have something to add - I will be very grateful. Good luck!

Completely common situation: the user tries to connect to Wi-Fi from his phone, but nothing happens. After reading the information below, you will learn why this happens and how to solve the problem.

Initial phone check

Manufacturers are actively working on improving mobile stability operating systemsBut periodically any program gives a failure. That is why the solution to the problem is recommended to start with the inspection of the operability of the phone. For Android, iOS and Windows Phone (Windows Mobile) recommendations in this case are identical. Stick the following sequence.

1. Restart the device and try to connect to Wi-Fi again.

2. Evaluate the number of connection signal indicators. If there are less than 3, try moving closer closer to the router or other used wireless Internet source to improve the quality of the connection.

3. Make sure the charge saving mode is disabled. If necessary, connect the network adapter.

4. Disconnect Bluetooth. Wireless connections can operate in the same range, which is why interference is created.

5. Disconnect the "aircraft" mode, if active.

6. Try to activate access to your location information and connect to Wi-Fi - the legislation of some countries blocks a connection through wireless networks with an inactive state of said option.

If earlier WiFi connection worked

If in the past you successfully used the current network now, delete this connection from your phone's memory. To do this, go to the list of networks, click on a problem connection for a few seconds (before the appearance context menu) And delete the connection.

If nothing happened, try connecting from the phone to any other available connection. In this case, only employees of the service center will help with a large proportion of probability in this case with a large share of the probability - only employees of the service center will help to correct the situation.

Make sure if the connection works. To do this, try to connect to it using any other device that features Wi-Fi function. If the connection does not work, make changes to the router settings.

Important note! The order of login in the router settings is changing depending on the manufacturer and model of equipment. In most cases, to gain access, you need to enter the address 192.168.0.0 or 192.168.0.1 in the address bar of the browser. Standard login and password - admin. If it does not work, specify the relevant information for your router in the manufacturer's instructions.

Previously try simply restart the router - quite often they "hang", because of which access to the Internet is blocked.

Further procedure is as follows.

First, you must make sure that the security key entered. Try entering the password to connect to the selected access point again, but more attentive, with the "Display Symbols" option activated (Show Password).

If you do not remember the password, specify it in the router settings.

For example, the order of interaction with d-Link router. In your case, everything will be almost the same, minor changes can affect only the interface, the names of the menu items and other little things.

After hitting the router settings page, do the following:
Click the "Advanced Settings" button;
In the Wi-Fi window, open the Safety Settings link;
In the PSK Encryption key line, see the password and make sure that it is this combination that you enter when trying to connect to Wi-Fi from the phone.

Secondly, make sure that the router settings are correct - you need to check whether the DHCP technology is enabled. When it is turned off, the phone cannot receive an IP address, because of which the connection will not work.

On the Router Settings page, click "Advanced Settings" and find the LAN category in the Network window.

Activate DHCP if the function is disabled by moving the "Mode" string to the "Allow" state.

Save the changes, restart the router and try to connect to Wi-Fi from the phone.

If this does not help, there are 3 options:
call the provider support and find out if the Internet works at all and have not made any changes to the connection settings;
pass the phone into repair;
Pass to repair / replace the Internet router.

If our instructions did not help solve the problem, then write in the comment and we will definitely consider your problem.

The problem when the laptop does not connect to Wi-Fi is quite common and in most cases quickly solved. With absence wireless connectionIn the lower right corner, the user observes a cross-lured network icon. If this is not provoked by a network adapter malfunction, which happens rarely, then there are not so many causes of failure. They are both in a laptop and in the router.

A very simple option to determine the malfunction, it will connect to the router, from another gadget, if they find Wi-Fi, then the problem is in the computer.

No network connection due to laptop faults

The first and easier that can be done is to simultaneously use the FN key in the lower left corner and connect to the Wi-Fay on the computer. The latter may be on the side, but more often on one of the buttons of the group F, it is easy to find the antenna icon.

If after clicking the key combination several times, the device does not want to connect, we look for the problem in the other. Sometimes access error may occur due to the installed antivirus program, which blocks all suspicious connections. In this case, you need to temporarily disable the antivirus and check the signal, if necessary, reboot.

Check Drivers

An example will be shown on a gadget with Windows 7, because it is considered more common, and in most cases the wireless network interruptions are observed on it. To check the application, the user needs to right-click on "My Computer", after clicking on "Properties", then "Device Manager", then " network adapters" We see the program in the picture, we need to choose Wireless Network Adapter, some names may be different.

If Wireless Network Adapter is missing in the list provided, then you need to go to the company's website and download the necessary program. If we see that the device is turned on, as it should be, but the problems of the connection with Wi-Fi did not leave, it means that the case is not in the driver, we try the following method.

Enable Wi-Fi through the network management center

To configure Wi-Fi using the control center, you need to click on the communication icon in the lower right corner. In the pop-up window, the inscription "Network and Common Access Center" appears at the bottom.

Now, in the left, upper corner, click "Changing the Adapter Parameters".

If there is no connection, then it is necessary to fix it, then a yellow star will appear on the network icon, which indicates the available connections and the normal functioning of the adapter.

If a wireless adapter Included, but eliminate the problem still fails, the laptop does not see Wi-Fi when the adapter is enabled, the icon is still marked with a cross, looking for another reason.

Auto-tuning WLAN.

It happens less often that the device cannot connect to the router due to the disabled WLAN setup. To get into it, you need to press the combination of the Win + R buttons, after which the window pops up.

In the field, enter the text that is visible in the SERVICES.MSC screenshot and confirm the action. Local services are now available to the user, it must choose and run the WLAN auto-tuning service.

Windows error

Often, at the time of connection, the "Windows cannot be connected to (network name) pops up.

In some cases, "troubleshooting" helps to solve the situation automatically or describe the existing conflict, if this happens, it is worth looking for a problem further.

The network disappears when leaving the sleeping mode

With the fact that the laptop does not connect to the Wi-Fi network collides not only seven, but also other operating systems. To eliminate the problem, it is recommended to deactivate the "permit to disable this device to save the electricity". For which go to the "Start", then in My Computer, then "Properties" and "Device Manager".

In the "Network Adapters" click the "Network Adapters" click, then click the mouse to the "Adapter of Wireless Networks", select "Properties".

The final stage is a choice of "power management", removing the mark on the "resolution of the disconnection of this device to save the electricity", confirmation and reboot of the gadget.

No network connection after updating

As an existing malfunction, the following can be noted. Sometimes users change passwords or encryption types, after which they do not know what to do and how to restore the connection to hidden Network, because before that everything happened automatically. To solve this task, you should remove the existing network on the gadget and connect to it again.

Deleting occurs simply enough, you need to go to the "Network and Shared Access Center" by clicking on the web icon on the right, in the bottom corner, after which it is possible to select the "Wireless Network" tab.

By choosing a network, click the mouse and click "Delete". After the removal procedure, we connect it again and enter another password if it has been changed.

The device does not accept the password from Wi-Fi

This seemingly simple problem, it turns out also relevant. When the user's laptop finds its network, it requires a key, but it does not fit. First you need to double-check the correct encryption, if you forgot it, do the following:

• go to the "Network Management Center" Click on a network icon, here we see the network to which this laptop has previously connected;
• select the desired connection and click the mouse, click "Properties";
• moving on the Safety Column;
• we do confirmation near "Display Input Entered Signs";
• we are looking for a password on the network security key tab.

Additional video material on the subject of laptop loss to Wi Fay:

If there is no encryption display, you can try to find it in the router settings or try to conduct a procedure from another PC. When Windows XP and newer versions, the user is better to use the WirelessKeyView program. After opening the application, we find our network in it and watch the password.

How to find a password in the TP-LINK router settings?

To use this method, you need to connect to the router through the cable or try on the working device to enter in the search line 192.168.1.1. In the window that opens, enter the username and password as in the documents. The wi-fi key will be listed in the Wireless Password column.

No wireless network due to problems in the work of the router

If the laptop stopped working with a previously connected network, then the reason is most likely in the router itself. Stop distributing wi-fi it can when:

• improperly connected;
• failures in the work of the provider;
• breakdown.

You can often correct the connection problem, you can restart the router and laptop. You also need to check the correct connection of all cables. If the Internet stopped working because of the provider, the user can only call support and find out the cause.

The broken router do not need to open independently, it must be given to the wizard, which after the diagnosis determines, it will work or will have to buy a new one.

If you did not solve the problem with the connection - additional video tips:

If you did not help connect to the Internet none of the recommendations, most likely the problem in the adapter breakdown (iron). This may occur after disassembling the laptop, for example, after it is purified from dust. In such a situation with the problem, it will be difficult to understand independently, you will need to appeal to the master.

Each user of the smartphone once faced such a problem as the infinite receipt of the IP address - the phone does not connect to WiFi And that's it! In this article I will tell you what to do if the phone does not see WiFi, and instead he constantly writes something like a "authentication error", "Obtaining IP" or "Saved". But I will immediately make a reservation, which is meant that firstly, the smartphone itself is in good condition. And secondly, WiFi network on the router is also configured correctly and everything works on other phones or computers.

I will list the most popular causes of errors at once:

1. Invalid IP address
2. Wireless radio channel
3. Encryption type
4. China, his mother ..

To directly dispose of a problem when the phone does not see WiFi, which are possible related to the router, try to restart it and make sure that it is turned on by a DHCP server. That is, the router automatically distributes the IP addresses to the devices connected to it.

In addition, you need to make sure that the network SSID is not hidden in the parameters wireless communication On the router - often to protect the connection from "prying eyes", activate this function, due to which the phone does not see the WiFi network, although it really works.

The reasons why the phone does not connect to WiFi

Now in detail about each item. The first thing I immediately do in case the phone does not connect to WiFi, - I ask a static IP address on it.

For Android and iPhone, this is done almost the same - go to "Settings\u003e WiFi", we see our active connection to the network and click on the arrow (on Android) or on the "I" icon on the iPhone / iPad.

• IP for your phone from the range of addresses specified in the router and available for use. If the address of the router 192.168.1.1, then for the phone you can assign 192.168.1.45, for example.
• Subnet mask - 255.255.255.0
• Router is an IP router. In most models, by default, it has an address or 192.168.1.1, or 192.168.0.1 - try them if it does not work, contact the network administrator.
• DNS is also an IP router, or you can use one of the Google public addresses - 8.8.8.8 or 8.8.4.4.

On the android phones It will be necessary to make a page at the bottom to the "IP settings" drop-down menu and change the DHCP to "Custom". Opens additional forms To enter the same parameters.

What if the phone does not see WiFi?

And some more ways to solve the problem, if we are talking about the fact that the phone does not connect to WiFi.

Possible reason Authentication errors can wage in the choice of radio channel for your wireless signal. I talked about it in detail in the article about, so long to explain how to configure it, I will not. And here it is worth noting that modern routers support work up to 16 channels, while the older standard, which the smartphones adheres, had only 11 channels. If your router is configured to the automatic channel selection mode, it can easily switch to channels 12 or 13 (it is 13 channels that are allowed for use on WiFi in Europe), and accordingly, the phone simply does not see it. So if you want a constant and stable connection on all devices, adjust the channel on the router manually from 1 to 11.

If the phone on Android, I want to upset you a bit - the Android kernel does not always work correctly with the WPA2-TKIP encryption type, so if you have such a type of encryption, it may be the cause of Internet problems, and that the phone is written "Connecting Saved" , "Obtaining IP" and other nonsense. This is especially true of cheap Chinese products.

China's theme cannot be circumvented and relative to the routers themselves - often their products have not quite standard operating modes - both by channels and encryption and by other indicators, so the modes of the Chinese router may not be fully understood by the "purebred" android. Exit - change the router to produce a better brand and model class above.
