Why can't I connect to the internet via wifi. Can't connect to my WiFi

The Internet and the latest electronic technologies are very closely intertwined in our lives. And sometimes problems with access to the Internet can cross out all our plans and interfere with our work or leisure. The phone not only helps to be in touch, but also opens the door from anywhere to the world wide web, to the Internet. At the same time, no one is immune from sudden failures, and then the question arises: why does the phone not connect to the WiFi router? This information also applies to those users who do not know why the tablet does not connect to WiFi.

Consider the typical reasons below. It must be said right away that the solution can be "hidden" in simple manipulations with the phone. Therefore, apply all the methods described below, without thinking that this will not help in your situation.

What could be the reasons for non-working WiFi in a phone or tablet

First you need to restart your phone and turn off / on the Wi-Fi network on your phone. Then reboot the router (router). If there is still no network, then the matter is different. It can also help - remove the battery and reconnect, then restart the phone.

The causes of the problem may be the presence of incorrect network or router security settings, as well as the channel operation mode. What errors most often we can observe on our device?

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

What can be the solutions to make the phone or tablet connect to WiFi

So here are the possible solutions to your problem.

Deleting a WiFi connection

The first thing I could advise you is to delete the connection that is saved on your phone. To do this, select the network through which you accessed the Internet and click on "Delete" or "Delete this network". You can see what it looks like in the screenshot below:

Then try to connect to that network again.

Rebooting the router

Sometimes, if there is a problem connecting not only the phone, but also other devices, you just need to restart the router. A small note: you must not just pull out and plug in the outlet after a second, but unplug the router's power cable for 10 seconds and only then plug it in again.

You must wait for some time so that there is no power left in the router. Such a scheme is often needed with other devices that are powered by energy. By the way, you can use the button that is on the router itself according to the same procedure that I described above.

Change the channel in the router

If you haven’t changed any settings and the connection with your router has always gone without problems, then you should try changing the Wireless operation channel (Wireless network). This happens very rarely, but there is a small percentage that this setting can help you.

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

Check the password you enter when connecting to WiFi

If your phone shows an "Authentication" error, then the problem may be an incorrect password or incorrectly set security settings.

The first step is to check that the password you have entered is correct. How to do this, because some users may not be asked to enter a password? You need to delete your connection and re-enter the password by clicking on your network. When entering a password, always be careful. If you forgot your password, you can view it in the router settings.

Here are articles that will help you in this procedure:

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

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

One of the most common problems is when the message “Saved, WPA \ WPA2 protection” is displayed on the phone, and at the same time the connection icon can show a connection, but there is still no Internet in the device.

If the options described above do not help, then you need to check the mode / speed of the Wireless (wireless network) in the router settings, since the phone cannot always support the router's mode. To do this, you need to set the network mode to automatic or mixed instead of b, g or n.

If you can't fix the problem and you're still in a dilemma why your phone won't connect to WiFi, try changing the encryption/security type I mentioned earlier:

• WPA/WPA2
• WPA-PSK

These are the settings on my router:

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

Then - the whole same scheme: save the settings, restart the router, delete the connection on the phone and connect by entering a new password when prompted. Keep in mind that the new password will need to be specified in other devices that use this router. For example, if you have a laptop or computer at home, then you need to reconnect to WiFi by entering the new password that you specified in the router.

Channel Width

Change the channel width (Channel Width) in the router settings. Usually there are several options: Auto, 20MHz and 40MHz. After the change, save and reboot the router.

If there are other options, then try them.

MAC and IP address filter

Make sure the MAC or IP address filter is disabled. If you activated this function in the router and did not specify which MAC and IP addresses can connect to routers, then the problem may be in this router setting.

Here are the most common reasons why your tablet or phone won't connect to WiFi. I hope one of my tips will help you.

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

Here is an example where the user could not connect to WiFi from the iPad:

Let's analyze the problem situation when the phone connects to Wi-Fi, but there is no Internet. It looks like this: next to the name of the wireless network it says “Connected”, but when you try to open any site in the browser, an error is generated Web-page is unavailable or 404 Not found. Chrome still writes in such cases. The same goes for other software - all sorts of programs that use the Internet connection for their work, or at least check for updates on startup, will also give an error connecting to their web server.

In this article, we will detail how to solve the Internet problem on your computer, phone or tablet. Read carefully, follow all the steps and you will definitely find the reason why you do not have an Internet connection with a working Wi-Fi connection.

Collection of information about the problem

Before making any changes to the Wi-Fi settings of your router, computer, or phone, check the following points. This can make it easier to find the reason for the lack of Internet or narrow down the search:

• Is the Internet paid for and are the funds on the account running out?
• Is there access to the Internet by wire from a desktop computer?
• Is it possible to access the Internet via Wi-Fi from other devices that use the same Wi-Fi router?
• Does the problem with the Internet connection persist when connected to another Wi-Fi network?

Depending on the answers to these questions, it may already become more or less clear to you what the problem is most likely. For instance:

• if there is no Internet at all - neither by wire nor by Wi-Fi, then the reason may be either blocking access on the provider's side or a malfunction of the router. Next, we check with the provider whether everything is in order with the line and the account, and then we check the performance of the router.
• if the Internet is on the PC via a wire, but not on any device via Wi-Fi, then the problem most likely lies in the wireless network settings of the router. The same conclusion can be drawn if the Internet appears and works without problems as soon as you connect to another Wi-Fi network from the same device
• and if it turns out that all devices are in order, and only one does not have an Internet connection, then the problem is obviously in this “client”.

Wi-Fi is connected, but the Internet is not working. What to do?

So, if your Wi-Fi is really “connected”, but there is no Internet (sites do not load, Skype and Viber do not connect, a yellow network icon is displayed on the laptop with the notification “No Internet access”), follow these steps to fix the problem. The steps are listed with a probability factor.

1. Restart your router

Sometimes the unexplainable happens failure on the router . At the same time, the local network and Wi-Fi work fine, but there is no access to the Internet. This can happen when the router is running for a very long time without reboots and when changes are made in the provider's network. Just in case: it is written how to reboot D-Link remotely.

2. Reboot the device where there is no Internet connection (phone, laptop)

Sometimes on a smartphone (tablet, laptop) a certain crash (glitch), which can cause a similar problem. Visually, everything seems to be fine, but there is no Internet for no apparent reason. In order to avoid such a failure, restart the device.

3. Reconnect to Wi-Fi network

This step is very important, despite its simplicity and boldness at first sight. You need to forget the Wi-Fi network, and then connect to it again by entering the password (security key). This may resolve the issue and restore your Internet connection, for example if network settings have been changed user or virus.

4. Set the correct date on your Android device

Wrong date may be the cause of the internet problem. In this case, sites will open, but Antivirus, Google Play Store, etc. may not work. .

5. Disable Proxy Server

If a proxy server is enabled on your computer or Android device, you may also experience a situation where Wi-Fi is connected but there is no Internet. Usually this problem occurs on Android.

6. Check the Internet connection settings on the router

Go to the WAN or Internet settings on the router. (). Check to be specified correct connection settings , such as:

• type of connection with the provider (see the contract or on the provider's website);
• login and password, if required (see in the contract);
• whether the MAC address is correct (check in the contract. If you reset the router, you may have to go to the ISP's office with a passport and contract and ask to register a new MAC address of the router's WAN port).

If your provider uses a PPTP connection, and the settings on your router have gone wrong and now IPoE (dynamic IP) is selected instead of PPTP, then naturally the router will not be able to connect to the Internet. In this case, the sites will not open on any device.

7. Change your wireless channel

Wireless equipment that is in the vicinity and operates on adjacent channels may create interference your router. Try changing the Wi-Fi channel.

And it would be even better to first check which channels are freer. This can be done using the Android app or InSSIDer for Windows.

8. Install WPA2-PSK + AES encryption for your Wi-Fi network

The WPA2-PSK encryption algorithm is the most secure. AES encryption ensures high speed and security. Most devices, even not new ones, successfully work in WPA2-PSK mode with the AES algorithm.

Wi-Fi Connected But Internet Not Working: Other Causes of the Problem

Weak signal

If there is too much distance from the client device to the router, there may also be such a problem: the device received an IP address, but there is no Internet. Therefore, you first need to check if the Internet appears when approaching the router (if possible). Then - if the problem is precisely in the distance - somehow try to reduce it. If your router is yours, place it in the middle of the house.

Some organizations provide free Wi-Fi, but in order to be allowed on the Internet, you need to launch a browser, enter a password or go through some other authorization procedure. For example, specify a phone number and enter a code from SMS. It is better not to contact such networks and do not enter any information about yourself in order to avoid problems. It is much easier to find another access point without such nuances.

If you've done everything but still don't have an active Wi-Fi connection to the Internet, there's another option: set up a static IP address. This method is not a solution in the full sense of the word, but in some cases it helps to get around the problem and gain access to the Internet. To do this, on your smartphone, call the properties of connecting to a Wi-Fi network, check the box Show advanced options and select Static IP:

A fairly common problem today is that WiFi does not connect on a laptop. Usually, the lack of data transmission over the wireless interface is due to incorrect software settings. The first item on this list is the accidental disconnection of the adapter on the keyboard or using a special toggle switch on the case. Next, you need to check the driver (the program that controls the operation of the adapter) and, if necessary, reinstall it. At the last stage, we check the network settings. phased

fulfilling all these points in most cases allows you to fix such a problem when WiFi is not connected on a laptop.

Turn on the adapter

The keyboard of most modern mobile PCs has an extended function keyboard. It can be activated by pressing a special key - "Fn". In this case, the standard character set stops working, and you can only use the additional one. It includes a key with an antenna and outgoing waves. On most models, it is in the "F1" ... "F12" function set. If you immediately press "Fn" and without releasing its key with the antenna and waves moving to the sides, then the current state of the adapter will be inverted. If it was on, it will turn off. To return it to its original state, you need to press the previously given key combination again. It is important to pay attention to the WiFi LED indicator. If it is off, then it will have to turn on, then the adapter will be in the on state, and it will be possible.

The second possibility to turn off the wireless network card is using the toggle switch. Its principle of operation is similar to the previously given one, with the same combination on the keyboard. When translating it from one position to another, the picture will be similar - WiFi is not connected on the laptop and the corresponding indicator does not light up. To enable the adapter, it must be reset. Depending on the model

mobile PC, both the first and the second method of disabling can be used. In premium models, their combination is possible.

Checking the driver

Next, you need to check the correct installation of the network adapter driver. Its failure can cause the laptop not to connect to WiFi. First you need to find the disk that comes with the device. If not, then download the installer from the website of the official manufacturer on the Internet. Then we go to the address Start\Panel Here we open the item "Network adapters" and look at the wireless card. If there are no icons opposite it, then we proceed to the next step. Select our wireless adapter with the left mouse button and press "Del". This removes existing drivers. Then we start the installation of new ones from the disk or the downloaded file. After that, it is recommended to reboot the system. If this does not solve the problem, proceed to the next step.

Checking network settings

At the final stage, we check the connection settings. For this we open

double-click the left mouse button "Current Connections" (label with increasing sticks on the right side In the list that opens, select the properties of the required Next, you need to check the type of encryption (it must be the same as on the router) and the password for access. If the password is accidentally changed, then you need to check the PC for viruses.After all three stages, such a problem, when WiFi is not connected on a laptop, in most cases is solved.

Conclusion

If all the operations described in the article are performed, but the result is not achieved, then it makes sense to seek help from a qualified specialist. As practice shows, in most cases, the proposed manipulations allow you to solve a problem in which the laptop stopped connecting to WiFi, and wireless network transmission is restored.

There are many reasons why a laptop won't connect to a Wi-Fi network. In this article, you will find a guide to solving the main options for this problem.

Why the laptop does not connect to Wi-Fi

The most common problems with connecting to a wireless network occur in the following cases:

• incorrectly set (knocked down) router settings;
• the Wi-Fi adapter on the laptop is deactivated;
• the driver for the wireless adapter is missing or damaged;
• the Wi-Fi module of the laptop is out of order;
• operating system crashes.

My laptop won't connect to Wi-Fi - what should I do?

It is worth noting that most often problems with connecting to a wireless network are due to incorrect router settings. It is his parameters that should be checked first.

Check the operation of the router

First, make sure the router is connected to the network and is active. Then check if other devices can see the network that the router creates. Use for these purposes, for example, a smartphone or other laptop.

If other gadgets also cannot detect the network, then most likely the Wi-Fi connection is deactivated on the router.

The first thing to do in this case is to simply reboot the router and check its operation again.

If there are no changes, then do the following (considered on the example of a DSL router):

1. connect to the router using the cable that came with it;
2. go to any browser and enter 192.168.0.1 or 192.168.1.1 in the address bar and press Enter;
3. in the authorization window that appears, in the "Username" and "Password" fields, enter the word admin and click the "Login" button;
   
4. go to the "Set up Wi-Fi" tab;
   
5. make sure the checkbox "Enable wireless connection" is checked, then click "Next";
   
6. if necessary, make connection settings (to find out the exact parameters, contact your provider);
   
7. Don't forget to save your changes at the end.
   

Laptop sees Wi-Fi but won't connect

The situation is slightly different when the laptop sees Wi-Fi, but does not connect to the network. The following are ways to resolve this issue.

Make sure you enter the correct password

Probably one of the easiest options that can occur in this situation is entering an incorrect password. Make sure the password you enter when trying to connect is correct.

If you have forgotten your password, you can easily recover it by doing the following:

1. connect to the web interface of the router as described above, but this time select "Manual configuration" from the menu;
   
2. then go to the Wi-Fi tab;
   
3. select the "Security Settings" tab;
   
4. in the line "PSK Encryption Key" will be your current password, which, by the way, can be changed here.
   

Check your MAC filter settings

The MAC filter is a special service that filters devices that try to connect to a wireless connection. Sometimes such a service can be the reason why the laptop sees Wi-Fi, but does not connect to the network. To solve the problem, you can try disabling the MAC filter.

The process of disabling the MAC filter for a DSL router is:

Check laptop Wi-Fi module

If everything is in order with the router and other devices can easily connect to it, then you need to deal with the laptop itself.

First of all, check that the laptop's Wi-Fi module is turned on. Depending on the laptop model, a certain combination of function keys, for example, Fn + F5, or a special switch located on the gadget's case, may be responsible for activating the module.

Make sure the Wi-Fi adapter driver is working correctly

If the wireless module is active, but the laptop does not connect to Wi-Fi, then you should check the Wi-Fi adapter driver.

To do this, use the following instruction:

If there is an exclamation mark next to the module, this means that the driver or the device itself is not functioning correctly. Double-click on the adapter and in the window that appears, read the error that has occurred.

The easiest way that can solve this problem is to uninstall the current driver, reboot the system and install the driver again.

Adjust your wireless settings

If your laptop sees Wi-Fi, but does not connect, and you have already tried the above troubleshooting steps, then you should check your wireless settings.

Instruction:

After these manipulations, try again to connect to the wireless network.

If Android does not connect to WiFi, then most often the user sees the message “Obtaining an IP address” or the notification “Authentication failed”. Another common connection error - Android writes "Saved, WPA / WPA2 protection", but does not go online.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

Possible causes of failure

If Android cannot connect to Wi-Fi - for example, instead of an active Wi-Fi icon, you see a gray button and an exclamation mark icon - then this may be due to:

1. Wrong from Wi-Fi.
2. Setting an unsupported security type or wireless standard in the router settings.
3. Problems with Android firmware.

The first step is to understand which device is having problems. If only your phone does not connect to the point, then the reason should be sought in its settings and firmware. If the wireless network is not found by any device, then you should check the settings of the router.

"Obtaining an IP address" message

If a message with the text “ ” appears when you try to connect, but the connection is not established, then the reason for this may be that the DHCP server is disabled in the router settings or there are problems with Android. A simple reboot of the router may help.

If the DHCP server fails, restarting the device will fix it. When saving the error:

1. Open your router settings.
2. Make sure the DHCP server is enabled.

Depending on the router model, the order of enabling / disabling DHCP may vary, so you need to look for instructions for your device.

Authentication error

If the connection authentication fails, then the problem is most likely caused by an incorrect Wi-Fi password. To resolve the error:

1. Forget the wireless hotspot on your phone/tablet.
2. Reboot your router.

1. Change your password using only latin letters and numbers.
2. Make sure WPA2-PSK is selected for network authentication.

If the phone does not support the WPA2-PSK standard, then select another mode - WPA, WPA2. It is clear that in the subway or shopping center you cannot do this, so the only thing left to do is to put up with it. But at home or in a hotel, you can access the router and check the parameters of the wireless network.

Saved, WPAWPA2 protection

If the connection is made without a password, then there can be no authentication error. However, there is another situation - the network is saved, but . Rebooting the router usually helps, but sometimes you have to go deep enough into the settings.

Also, look at the number of allowed devices. If it is "0", then there are no restrictions.

Network discovery issues

If , then changing the region and channel usually also helps. If Russia is selected in the settings, the router automatically connects to channels from 1 to 13. However, some devices do not support channels greater than 10 - this is how an error appears. To fix it:

1. Put the USA region - it has only 10 channels.
2. Manually change the channel to one of the range 1-10.

If this does not help, then make sure that the network is visible to other devices. Perhaps the cause of the problem should be sought in the operation of the Wi-Fi module on Android.
