The phone stopped connecting to my home wifi. The Internet does not work when connected to open Wi-Fi, or why you cannot connect to a free (unsecured) Wi-Fi network

If your phone does not connect to Wi-Fi, this may indicate incorrect settings or problems with the router. Troubleshooting connection problems wireless point access must begin with checking the functionality of the devices. This instruction Suitable for iPhones, as well as Android smartphones from the following companies: Asus, Honor, Samsung, Beeline, Huawei, Meizu, LG, Motorola, HTC, Nokia, Fly, Sony, Lenovo, Xiaomi, Alcatel, ZTE, etc.

If it doesn't work WiFi connection on an Android smartphone, the following factors may contribute to this:

Lack of local wireless network or bad connection in room;
The security key was entered incorrectly;
The smartphone is not configured correctly;
System error in the operation of the Android platform (the driver has crashed);
Incorrect router settings;
Router freezes.

To troubleshoot connection problems global network Internet, most often a call to the provider’s technical support is enough. Often the reason lies in a malfunction of the company’s equipment, and it can be problematic to understand why Wi-Fi on the phone does not connect without two-way diagnostics.

First actions

In order to find out why your phone does not connect to Wi-Fi, you need to follow these steps:

Reboot the router itself (it is advisable to keep it unplugged for a couple of minutes).
After restarting the phone, enter the Wi-Fi settings and delete the previous access point.
Start searching for the network again, being as close as possible to the signal source. After connecting to the network, you must enter the password again.

If Wi-Fi is not connected using this method, you will have to move on to more complex manipulations.

Enable and disable Airplane Mode

Very often, this method helps. Airplane mode turns everything off wireless interfaces on gadgets, regardless of their manufacturer. The method works equally well for both iOS and Android devices.

Another one of the most effective ways, most often helps in situations with gadgets from Samsung, HTC, Sony, Lenovo and others based on Google operating systems.

In this case, drivers and settings are completely unloaded from system memory, followed by loading correct parameters. In 90% of cases it helps solve the problem, but most likely this will be a temporary measure and it is worth observing the behavior smart phone. There is a possibility that Android was infected with viruses.

Checking the security key

It often happens that mobile phone does not connect to home Wi-Fi because the encryption key for the WEP, WPA or WPA2 standard is incorrectly designated. Therefore, you need to specify it again by checking the “Show access code” box in order to prevent errors.

How to find out the Wi-Fi router password through settings

If you can't remember your password, you can refer to the access point's security settings to find it:

In the PC toolbar, open “Internet Access”, then right click mouse click on the network name.
Select "Properties". In the window that appears, open the “Security” tab and check the box called “Display entered characters.”

After the security key is displayed, you need to enter it into your phone and connect to the network. It is better if the indicated characters are displayed on the smartphone in order to avoid entering incorrect data and wasting time again.

If the settings on your laptop (computer) are also lost, you need to find out the router password, because... every router has its own special IP address. In almost all models it is printed on a tag that is glued to the back. If you have saved the instructions, you can see the password for entering the settings in it.

In 90% of cases, the login and password to enter the router interface is admin.

Instructions

The algorithm of actions that will make it easy to find out the router password is very simple:

Enter device settings using a laptop or desktop computer using power cord, which comes with the router.
Enter the IP in the address bar of any browser Wi-Fi router. Next, fill out the fields with access data from the router management page, which are almost always provided on the back of the router (usually set as admin/admin by default). The settings page will then be displayed.
If information from reverse side no, let's start command line with the Start+R keys. In the window that opens, write CMD and press “Enter.”
Specify the IPCONFIG command. Connection details will appear on the screen. We find the item “Main gateway”. The IP address that opens should be copied into a line in the browser. After that, enter your password and login and click “Login”.

It is worth noting that the settings of many routers are identical, the only difference is appearance and individual functions.

How to get an access code using LinkDir-615 as an example:

At the bottom of the screen, click on “Advanced settings”.
In the “Wi-Fi” menu we find “PSK encryption key”, where the required network password will be indicated.

Conclusion

If the above instructions do not help, you need to call hotline provider and clarify whether changes have been made to the connection settings. The lack of adjustments may indicate a malfunction of the router itself, so you will have to send it in for repairs or replace it with a new one.

Public or home Wi-Fi the network, as a rule, does not limit the user’s data transfer speed, and the signal is more stable and of better quality. And it is not surprising that we immediately switch from mobile network to the wireless network as soon as possible. However, it is often impossible to connect the first time. Therefore, in this article you will learn what causes connection failure, as well as troubleshooting methods.

Why won't Wi-Fi connect on my phone?

There are several reasons that prevent you from connecting to a wireless access point:

The password was entered incorrectly.
The router is overloaded with the number of consumers.
Phone malfunction.
The router is malfunctioning.
Disabled DHCP protocol.

Connect to wi-fi on your phone: enter the password correctly

If a password is required to connect to your access point, you may be entering the wrong combination. The security key is case sensitive. Therefore, if the password includes capital letters, then writing the correct combination, but in small letters, will not work. Please check the combination to be case-sensitive and try again.

The router is overloaded: try to connect later

Public networks that require a password or allow free connections are always overloaded with a vast number of connections. As a result, the router is not able to accept new users due to the channel congestion. The solution is to reconnect later or use a different access point.

Failure when connecting to a Wi-Fi network: reboot the phone

Often the phone is unable to connect to the Wi-Fi network due to a system glitch in the firmware. As a result mobile device does not see the network, or the connection hangs at the authentication stage. Usually the problem is solved by rebooting the phone.

Sometimes failures occur in the operation of the router. In particular, when the device is regularly operated under high load, due to overheating, or a model from the budget segment. The problem can also be solved by rebooting. If problems appear again after a while, you should think about cooling or replacing the router.

Checking the router settings

A connection error can also occur if DHCP is disabled in the router settings. You should open the router configuration console and make sure that the DHCP protocol is activated.

Conclusion

Now you know the main problems due to which the phone does not connect to the Wi-Fi network. Check your password, restart your phone, check your router settings, or try connecting later. If the methods described in the article do not help, then you should diagnose the router and phone to avoid hardware failure.

Wireless Internet is now found in almost every home or public institution. Unfortunately, sometimes problems occur that make it impossible to connect to world wide web. IN this material Let's figure out why the device doesn't connect to Wi-Fi.

All reasons are conditionally divided into two categories: related to the operation of a smartphone or tablet and associated with the router. Let's take a closer look at each type of problem.

Problems with your mobile device

Your smartphone or tablet may experience the following reasons for not being able to connect to a wireless network:

note

If the indicated problems are not found on your mobile device and it connects perfectly to other networks, then you should check the router.

Often the Android device does not connect to Wi-Fi due to incorrectly configured router. To open the settings, you must use a browser on a device that is connected to this network, such as a computer. IN address bar the connection gateway is entered, usually this "http://192.168.0.1/". If specified address did not work, you can find out yours by opening "Intelligence" in the status window of the current local network connection.

It is important to know

Usually the same word is used as the first and second meaning - admin.

After logging into the control panel of the router, you should check the following items settings:

Region. The correct region depends on automatic settings devices, because different countries apply different standards data transmission.

Channel. If the line contains a value from 1 to 13, it is better to set it to “Auto”. However, some devices may not support channel higher than 10.

Wireless mode. You should experiment with the settings here. If Android does not connect to Wi-Fi in position N, it needs to be replaced with G, etc. The “B/G/N mixed” mode is considered universal. After each change, you need to save the result and restart the router, as well as reconnect on the phone.

Maximum number of clients. Zero is an unlimited number; if the value is different, it needs to be changed.
Network authentication or encryption type. During testing, you can completely remove password protection by setting the type to “Open”. In the future, you should try replacing “WPA2” with another one if you experience problems with the connection.
Wireless MAC address filtering. Sometimes Android does not connect to Wi-Fi because the user accidentally excluded his phone or tablet from the list of devices that can connect. If you do not understand this parameter, then it is better to set its value to the “Disabled” position. As a result, any device will be able to connect to the network if it has a password.

These are all the basic settings that can have an effect Negative influence the ability to connect a smartphone to Wi-Fi. More advanced users can update the router firmware. The procedure is easy to follow:

Visit the official website of the device manufacturer and download the firmware to your computer.
Open the router settings and go to the “System Tools” section, then “Software Update”.
Select the downloaded file and click the “Update” button.
Do not turn off the power to the PC and router until the procedure is completed.

New versions of software usually contain fixes that can resolve connectivity issues. When downloading a file, special attention should be paid to matching the device model, otherwise there is a risk of failure during the firmware process.

Modern mobile devices can have different power, different functionality, but they are all designed to work with Wi-Fi and the Internet. And surely every user mobile gadget At least once I have encountered a situation where a phone or tablet does not connect to a wireless network. In this article we will look at typical mistakes problems that occur on Android devices when trying to connect to Wi-Fi, and we will tell you about methods for eliminating them.

Typical errors connecting to a Wi-Fi network

If you successfully connect to a wireless network, a message should appear under its name Connected. Any other signature indicates that it was not possible to connect to the network for one reason or another. In practice, when trying to connect to Wi-Fi, the following error messages are most often encountered:

Message Saved.
Messages Authentication Error or Authentication problem
Infinitely stuck message Obtaining an IP address...
An authentication error occurred.

"Saved" message below the network name

Most probable cause: Weak signal.

Solutions:

try to reduce the distance to the access point. If the error disappears when the Android device approaches the access point, it means that it was observed due to the fact that the smartphone’s transmitter power was not enough. This, in turn, can be not only due to the large distance of the mobile device from the router, but also due to a clogged airwave - when there are a lot of people around wireless devices and networks.
try changing the channel on the router to a freer one.
try changing the channel width in the router settings.

"Authentication Error" or "Authentication Problem"

Reason #1: incompatible with client device security mode and encryption type.

Solution: If the mode is WPA2-PSK, try changing it to WPA-PSK.

Reason #2: Invalid security key.

Typically, if the security key does not match, the Android device will prompt you to enter a password. However, there are other manifestations.

Solution: Please enter the correct security key. Be careful with layout and register. It is strictly forbidden to use the Cyrillic alphabet in SSIDs and passwords, and the registers can become confusing. If you are in doubt about your password, temporarily set a 10-digit key on your router.

Reason #3: weak signal.

Solution: Check the network with more close range from the router. If the problem disappears when you approach the router, try finding a freer one wi-fi channel and install it on the router. Then reconnect to the network.

Endless Obtaining an IP Address

Reason #1: weak signal.

Solution: try reducing the distance to the access point (read above in point 2.)

Reason #2: The MAC address filter is enabled on the router. Your device's MAC address is not whitelisted or blacklisted.

If obtaining an IP address is blocked by a MAC address filter, errors may also appear on your smartphone:

Failed to obtain IP address;
Network is down due to slow internet connection.

Solution: add the MAC address of your device to the white list or remove it from the black list. If the router is not yours, ask your administrator to perform these steps.

"An authentication error occurred"

Reason #1: weak signal.

Solutions:

If possible, reduce the distance to the access point;
P try to choose free channel.

Reason #2: Invalid network security key.

Solution: Enter the correct security key (read above in step 2.)

Below we provide a checklist for troubleshooting most wireless network problems. If you do not want to delve into each individual case described above, follow sequentially listed actions. If after performing the action the problem is not resolved, move on to the next one.

Disconnect from the wireless network on your Android device. To do this, click on the network name in the list and hold for more than a second. When the menu appears, select Forget the network. After that, connect to the network again by entering the security key.
Reboot your router and Android device to eliminate the possibility of unexplained crashes and freezes. After rebooting the router and gadget, wait a couple of minutes and try to connect to Wi-Fi again.
Check the correctness of the wireless network security key (popularly “Wi-Fi password”). Set the key from 10 random numbers, so as not to get confused in layouts and registers.
Check your MAC address filter settings. Try temporarily disabling the filter and connecting to the network.
Check the region settings in the router. Please enter the correct region. Try choosing Russia, then the USA, then Chile. This may affect receiver sensitivity and transmitter power. Keep in mind that many router models may not have region settings.
Install on the router security mode WPA2-PSK And type AES encryption . Save the settings and wait a couple of minutes. Delete the network on your Android device and try connecting to it again.
Set mode Mixed 11b/g/n for maximum compatibility with various devices and standards. Save the settings and try to connect to the network after 2 minutes. For reference: if you install 802.11n only, only those devices that support the standard can connect to the router n.
Set the channel width setting to Auto. Save the settings and try connecting to the network again after a couple of minutes.
Do hard reset router and configure it from scratch. There are cases when this action corrects a router failure.

Cautions

Attention! Use only Latin characters and numbers in SSID and security keys! If you use Cyrillic in these fields, you may encounter the following problems:

you will not be able to connect to Wi-Fi from client devices;
The router may freeze and you will have to do a hard reset.

Remember! After making changes to any wireless network security settings on the router (key, security mode, encryption type), delete the network on Android devices and connect to the network again. Don’t wait for your smartphone or tablet to prompt you to log in to the network again. Yes, in some cases, Android OS detects the changed parameter better than computers with Windows. But it may turn out that after changes on the router, your device will simply start generating authentication errors.

⭐️⭐️⭐️⭐️⭐️ In this article I will analyze the situation when there is no Internet via WiiFi on Android. Those. The connection to the network itself is there, the Wi-Fi icon is active, but it is not possible to access the Internet and instant messengers (Telegram, Viber, Skype) and other applications (Instagram, VKontakte, etc.) do not connect.

In most cases, rebooting the smartphone or router that distributes the wireless network helps. Another reason could be software error in work Android and incorrect setting router.

This article Suitable for all brands that produce phones running 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.

I'll notice! If you are using public WiFi network or private corporate, then there is a high probability that they will block some social networks and messengers. This is often practiced and you will have to come to terms with the situation.

Checking Internet access

Before using your smartphone or router, make sure that everything is ok with the Internet. What could be wrong with it:

You didn't pay, so your provider suspended your Internet access. Make sure there is network access through the wire.
In the router settings there are restrictions on visiting certain sites or a traffic limit (common practice for open networks in public places).
There were problems on the provider's side.

After eliminating these factors, proceed to diagnostics, allowing you to understand in the operation of which device the cause of the problem is hidden.

The easiest way is to connect to the wireless network from another phone/tablet/laptop. If another device connects to the network, then the problem is in the phone, which cannot establish a correct connection.

Android glitches

Reboot your mobile device. If the cause of the problem was minor system failure, restarting the system will fix it.

After restarting, if the error persists, forget the network and then reconnect to it.

Forgetting the network and reconnecting helps resolve the inconsistency Wi-Fi settings on your phone and router.

If deleting the network does not help, check the proxy server status on Android. It should be turned off:

Go to the “Wi-Fi” section of the settings and select the network to connect to.
Check the "Advanced" option.
Make sure the Proxy Server field is set to No.

Increase

Another reason that the phone does not connect to the Internet may be the wrong date. To check it and change it:

Open settings.
Select the "Date and Time" section.
Set the time and date manually or check the “Network date and time” and “Network time zone” checkboxes.

Increase

After installation correct date connect to Wi-Fi. If the wireless network actually works, you will be able to access the Internet.

Checking and setting up the router

If, as a result of some kind of diagnostics, you find out that they occur on all devices that connect to the same wireless network, then look for the cause of the error in the router settings.
