A very common situation: a user tries to connect to Wi-Fi from his phone, but nothing works. After reading the information below, you will learn why this is happening and how to solve the problem.
Initial phone check
Manufacturers are actively working to improve the stability of mobile operating systems, but from time to time any program crashes. That is why it is recommended to start solving the problem by checking the functionality of the phone. For Android, iOS and Windows Phone (Windows Mobile) recommendations in in this case identical. Follow the sequence below.1. Restart your device and try connecting to Wi-Fi again.
2. Evaluate the number of connection signal strength indicators. If there are less than 3, try moving closer to the router or other source you are using wireless internet to improve connection quality.
3. Make sure Battery Saver mode is turned off. If necessary, connect the network adapter.
4. Turn off Bluetooth. Wireless connections may operate in the same range, which causes interference.
5. Turn off Airplane mode, if active.
6. Try to activate access to information about your location and connect to Wi-Fi - the legislation of some countries blocks connections via wireless networks unless active state the mentioned option.
If the WiFi connection worked previously
If you have successfully used the currently problematic network in the past, delete the connection from your phone's memory. To do this, go to the list of networks, click on the problematic connection for a few seconds (until the context menu appears) and delete the connection.If all else fails, try connecting from your phone to any other available connection. Failure in this case will most likely indicate a breakdown of the radio module - only service center employees will help correct the situation.
Check if the connection is working. To do this, try connecting to it using any other device that has Wi-Fi functionality. If the connection does not work, change the router settings.
Important note! The procedure for entering the router settings varies depending on the manufacturer and model of the equipment. In most cases, to gain access you need to enter the address 192.168.0.0 or 192.168.0.1 into the address bar of your browser. The standard login and password are admin. If this doesn’t work, check the manufacturer’s instructions for the information relevant to your router.
First, try simply rebooting the router - quite often they “freeze”, which is why access to the Internet is blocked.
The further procedure is as follows.
First, you must ensure that the security key you entered is correct. Try entering the password to connect to the selected access point again, but more carefully, with the “Display symbols” (show password) option activated.
If you don't remember the password, check it in the router settings.
As an example, the procedure for interacting with a D-Link router is shown. In your case, everything will be almost the same; minor changes may only affect the interface, menu item names and other little things.
Once on the router settings page, do the following:
click the “Advanced settings” button;
in the Wi-Fi window, open the “Security Settings” link;
in the “PSK encryption key” line, look at the password and make sure that this is the combination you enter when trying to connect to Wi-Fi from your phone.
Secondly, make sure your router settings are correct - you need to check if DHCP is enabled. If it is turned off, the phone will not be able to obtain an IP address, which is why the connection will not work.
On the router settings page, click “Advanced settings” again and in the “Network” window, find the “LAN” category.
Enable DHCP if the function is disabled by changing the “Mode” line to the “Allow” state.
Save the changes, restart the router and try connecting to Wi-Fi from your phone.
If this does not help, there are 3 options left:
call the provider’s support service and find out whether the Internet works at all and whether any changes have been made to the connection settings;
submit your phone for repair;
have your Internet router repaired/replaced.
If our instructions did not help solve the problem, then write in the comments and we will definitely look into your problem.
So you bought or were given a laptop or computer. The very first thing you will do is connect it to the Wi-Fi network. In the vast majority of cases, everything happens in a matter of moments. But let’s imagine a situation when Windows starts producing various kinds of errors, and the device does not see the connection. What can I do? Why doesn't my laptop connect to Wi-Fi and the connection icon is crossed out in red? Not very experienced users begin to give up. But don’t be upset, this problem is completely solvable. Read our guide and you will know how to connect to Wi-Fi.
Not everyone knows how to solve the problem with connecting to Wi-Fi
Let's look at the main factors why the Internet does not function and how to solve each of them. If you can't resolve the problem, you've come to the right place.
Turning on Wi-Fi
It often happens that the wireless module is deactivated. You can activate it in different ways.
Way 1: Using function keys
Absolutely all modern laptops are equipped with an Fn button. Its purpose is to control certain functions of the device together with the F1-F12 buttons. In some models, Fn launches auxiliary functionality, and in others, it returns the built-in Windows functionality to the F1-F12 keys.
Turning Wi-Fi on/off is one of its functions. Look through the F1-F12 keys to find one with an image of an antenna (on Lenovo models, this is a button with an image of an airplane that activates/deactivates airplane mode). Press the button or its combination with Fn. If successful, a network icon with an asterisk will appear in the system tray, representing the available networks. Choose yours and try to connect.
Path 2. Through Network Sharing Center
Try connecting using this method if the first one fails. To get into Windows connection management:
- Start - Control Panel - Network and Sharing Center - Change adapter settings.
- Right-click on the Internet icon in the system tray - Network and Sharing Center - Change adapter settings.
- For Windows 8–10: hold down Win+X - Network connections.
If the adapter is inactive, its image will be gray. Select it with a single click and in the menu bar just above activate “Enable network device”. A connection icon in the form of an antenna with an asterisk should appear in the Windows system tray.
Way 3. Through Device Manager
This method is suitable when you have activated Wi-Fi, but the laptop cannot connect to the network. Go to Device Manager:
- Start - Control Panel - Device Manager.
- Win+X - Device Manager.
- Search in Windows - type "Device Manager".
You will see a list of all available equipment. In the “Network adapters” column, find Wireless adapter. The name may contain the word Wireless. If the user sees an arrow in a circle next to the name, then he must right-click and select “Enable” (“Enable”). Again, the network icon should appear in the tray.
Driver installation
When there is no chip name in Device Manager, but instead, for example, “Wireless Network Adapter” is displayed, and there is an exclamation mark in the middle of the triangle next to the name, you will need to install a driver.
If you have a laptop, all you need to know is the device model. Then go to the manufacturer’s support website, download and install the driver for your operating system. If you have a computer, it is better to know the model of the Wi-Fi adapter; It is possible that you still have the box after purchase. If you don’t know for sure, double-click on it in the Manager, in the “Details” tab, select “Equipment ID” from the drop-down list and search the Internet for the code.
How to install the driver?
- As a normal program, following the instructions of the installer. You may need to restart your computer. In rare cases, the system does not see the driver installed using this method.
- Unpack the contents of the archive into a local folder. In Device Manager, double-click to open the properties window, in the “Driver” tab, click “Update” - “Search on this computer” - specify the folder with the unpacked archive. The system will install the driver.
Please note that it is best to download drivers for your OS version to avoid incompatibility. An incorrect driver is one of the reasons why the laptop failed to connect to Wi-Fi.
Setting up a network and router
Let's say that the computer sees the network, the connection is successful, but it does not allow it to connect to the Internet. There is a yellow icon next to the connection icon. Why is this situation happening?
Most often for the reason that the settings of the network chip differ from the settings of the router. Initially, it assigns each device an IP address automatically. Then automatic acquisition of an IP address must be activated in the module settings. How about making sure of this? Go to “Network Connections” (read above how) - “Wireless Network” - “Properties” - “IP Versions 4” - “Properties” - “Obtain an IP address automatically”. When the settings do not match, you cannot access the World Wide Web.
If it still doesn't work
Troubleshooting
The Windows utility will scan your computer for errors in the operating system and network card: right-click on the connection icon - Troubleshooting. The utility will begin scanning. Follow her instructions.
- Type of network problems - I have a different problem - Using a specific network adapter - Wireless network.
What when no steps are successful and troubleshooting reveals no errors? The laptop cannot connect to the Internet or does not see the network? In most cases, rebooting the laptop/router will help. It will clear temporary files, RAM of devices and, quite possibly, the computer will be able to connect to the network.
Radical problem solving methods
If you stubbornly cannot connect to Wi-Fi because Windows does not see it, you can reset the router to factory settings. On its back panel there is a small Reset button recessed into the body. Take a pin, press the button and hold it for a few seconds. After this, perform all adjustments from the very beginning.
You need to look for the “Reset” button near all other connectors
Well, if you managed to catch a virus, or system updates were not installed correctly, try Windows recovery.
Conclusion
We have brought to your attention possible solutions to all situations when the computer does not see the Wi-Fi network. In extreme cases, you may have to buy new equipment, but in most cases, fiddling with the settings is enough to save money.
We'll be glad to know yours personal experience in this question, what did you do when faced with the computer not being able to connect to Wi-Fi networks. We hope that you were able to resolve the issue by following our recommendations. Leave your comments below the article.
“I can’t connect to my WiFi” - topics with a similar name appear on various computer forums almost every day. And this is not at all accidental, because problems with wireless connections occur quite often. What could be the problem and how to solve it in this or that situation?
Check your internet connection
Before taking any action, make sure that the cable transmits the Internet. To do this, connect your computer to the modem or router directly using a wire. There is always a possibility that the problem comes from the provider (for example, when carrying out technical work, they usually turn off network access for users for several hours).
Checking if all devices are connected
Before asking the experts “what should I do if I can’t connect to my WiFi,” make sure that your network equipment is in an active state. First, the Wi-Fi indicator on the router itself should be lit. If the network is not enabled, you should enter the IP number (192.168.1.1 or 192.168.0.1) into the browser and connect it. You should also make sure that the appropriate adapter is enabled on the computer or laptop itself. This can be done through the Network and Sharing Center. Access" Windows (go to the tab responsible for the adapter settings and find the one that supports wireless connections). On some models laptop wifi turns on by pressing a certain button. You can try restarting your computer and trying to turn on the adapter again. If this does not help, you will most likely need to. If even reinstalling the driver did not help, you may need to reinstall the operating system.
If the computer “sees” Wi-Fi, but gives an error when trying to connect
“I did everything above, but I still can’t connect to my WiFi.” If your computer displays information about available networks, but when you try to connect, an error message appears on the screen, the problem may be due to an incorrect mode of operation of the router. Let's go to its settings (you already know how to do this from the previous paragraph) and change the mode from standard to mixed (Mixed), B/G/N or B/G.
Network without Internet access
This is perhaps one of the most common problems why WiFi won’t connect. Windows 8, by the way, is much more susceptible to this than previous versions OS. This happens because the computer receives an incorrect IP address or DNS server address. First you need to find out what exactly is wrong. To do this, open the list of available networks, right-click on the one you want to connect to, and select “Status”. If an IP address was not received or an incorrect one was received, next to the “IPv4 connection” line there will be a message stating that there is no access to the network. You can check this by opening “Change adapter settings” in the Network and Sharing Center. Having found your wireless connection, right-click on it and open properties, and then look at the IPv4 protocol. If any addresses are specified in the settings, write them down on a separate sheet (they may still be needed), and then change the options so that the IP address and DNS server address are obtained automatically. Confirm the changes made and check your Internet access. If this does not help, restore the default addresses used by the router.
Problems associated with incorrect DNS server addresses also lead to the Internet not connecting via WiFi. As in the previous case, they are displayed in the wireless network status window. In this case, next to the “IPv4 connection” line you will see the inscription “Without Internet access”. This is corrected, again, in the protocol settings. Try setting up automatic retrieval of the necessary addresses or entering “8.8.8.8” in the preferred DNS server column, and “77.88.8.8” in the alternative column (public addresses of Yandex and Google DNS servers).
We hope this article helped you, and the need to write to specialists with the question “why can’t connect to my WiFi” is no longer necessary for you!
If Android does not connect to WiFi, then most often the user sees the “Obtaining an IP address” message or the “Authentication Error” notification. Another common connection error is that Android writes “Saved, WPA/WPA2 protection,” but does not connect to the Internet.
This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
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 the reason for this could be:
- Wrong from Wi-Fi.
- Setting an unsupported security type or wireless standard in the router settings.
- 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 no device finds the wireless network, then you should check the router settings.
"Obtaining an IP address" message
If, when you try to connect, a message with the text “ ” appears, but the connection is not established, then the reason for this may be that the DHCP server is disabled in the router settings or problems with Android. A simple reboot of the router can help.
If the DHCP server fails, restarting the device will fix it. When saving an error:
- Open your router settings.
- Make sure the DHCP server is enabled.
Depending on the router model, the procedure for enabling/disabling DHCP may vary, so you will need to look for instructions for your device.
Authentication Error
If connection authentication fails, the problem is most likely due to incorrect input. Wi-Fi password. To resolve the error:
- Forget the wireless hotspot on your phone/tablet.
- Reboot your router.
Increase - Change your password using only Latin letters and numbers.
- Make sure that WPA2-PSK is selected for network authentication.
Increase If your 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 can't do it, so all you have to do is accept it. But at home or in a hotel, you can access the router and check the wireless network settings.
Saved, WPAWPA2 protection
If the connection is made without a password, then there cannot be an authentication error. However, there is another situation - the network is saved, but . Usually rebooting the router helps, but sometimes you have to go into the settings quite deeply.
Increase Also, look at the number of devices allowed. If it is “0”, then there are no restrictions.
Why doesn't my phone connect to Wi-Fi, although it recognizes the network? There are several types of this error:
- There is an endless and unsuccessful attempt to obtain the router’s IP address;
- The smartphone cannot connect to the network, but the access point remains;
- The phone does not find the network at all wifi;
- The connection occurred, but there is no connection to the Internet.
Let's look at all the ways to solve problems with the router. All types of errors can be resolved using the instructions below. Follow all instructions in order to resolve the error as quickly as possible.
Performance check and problem analysis
In more than 60% of cases, the user cannot connect to wifi due to short-term network failures. Before you learn how to connect your device to your router to troubleshoot a problem, complete all of the following steps:
- Reboot smartphone under control OS Android and your router. The wifi itself must be kept unplugged from the socket for several minutes;
- After rebooting the Android device, go to the wifi settings and delete the previously saved access point;
- Now search again (the phone should be as close to the router as possible during the search).
If you are unable to establish a connection using this method, proceed to the next instructions.
It is also necessary to check the password, since most users may simply enter it incorrectly. Because of this, the connection does not occur and it says “Saved”. To check the entered password, go to the Wi-Fi settings. Then go to view the options of the desired access point. In the password (or keyword) field, click on the “Show password” checkbox and make sure that it matches the one keyword, which is specified in the router settings.
How to view the password in the router settings? To do this, enter the configuration settings window and go to the “Wireless Security” tab. The password is the value in the PSK Password field. You can also change this value. After changing the password, save the settings and try logging in from your phone again.
Changing the access point name
If all your devices, except those running Android OS, connect to the router, you need to rename the access point. Some Android smartphones and tablets have one common bug - they are unable to recognize a network if its name is in Cyrillic or if the network name contains special characters.
Follow the instructions to change the name:
- Go to the router settings;
- Go to the main tab and in the SSD Name field, change the name of the access point. Remember, it should not contain additional symbols and letters in Cyrillic. Use only Latin alphabet and numbers;
- Save the settings and try to detect the network again.
Changing the Beacon interval option value
Almost all modern router models have a number of advanced connection features. You can fix the network connection problem by changing the Beacon interval parameter. Why is this interval needed? Its main purpose is to set the period of time after which telephone will try to receive a special packet from the router that contains information about the operation of the network.
As a rule, on all routers this value is equal to one second (or 100 ms). You can change this parameter yourself to 45 or 70. For most Android smartphones, this value is suitable.
Follow the instructions:
- Go to your router's settings;
- Go to the "Advanced Settings" tab wireless connection" Another name is "Advanced Wireless";
- In the Bacon Period field, enter the required value and save the settings;
- Reboot your router;
- Try connecting to the Internet.
Selecting a connection mode
The cause of the problem may be incompatibility of the communication standard of your smartphone and router. To do this, you need to change the connection mode in the router settings.
Follow the directions:
- Go to your router's settings and enable the advanced wireless network settings tab;
- Find the Mode field and change its value one by one. After each change in the standard, save the settings and try connecting to the Internet from your smartphone.
Channel changes in router settings
If your Internet connection is lost suddenly (you haven't done any access point add-ons before), it's possible that the previously used channel is no longer suitable for your network and needs to be replaced.
To do this, follow the instructions below:
Notice! This method This solution is only suitable if absolutely all devices are connected to the router, but there is no Internet connection.
- Go to your router settings via your computer using any browser;
- Find the tab with wireless network settings;
- Then in the “Channel” tab, change the value from “Auto” to any other. Save the settings and reboot the router. Now connect to the Internet again. If necessary, try connecting to a different channel.
Using third-party utilities to reorganize the connection
Using some utilities, you can find out how to connect your phone to the router without errors. Also, such applications help eliminate the error by scanning the entire system of a smartphone or tablet. Let's look at a few useful programs:
- WiFi Fixer– a free utility for diagnosing and quickly troubleshooting problems related to connecting to a router. You can download and install the program on your device from official page in the Google store https://play.google.com/store/apps/details?id=org.wahtod.wififixer.
