Why can't my phone connect to wifi. Why the phone does not connect to a Wi-Fi hotspot

A public or home Wi-Fi network, as a rule, does not limit the user in data transfer speed, and the signal is more stable and better. And it's not surprising that we immediately switch from a mobile network to a wireless network at the first opportunity. In this case, it is often impossible to connect the first time. Therefore, in the article you will learn what leads to a connection failure, as well as troubleshooting methods.

Why can't wifi connect on my phone

There are several reasons that do not allow you to connect to a wireless access point:

1. The password was entered incorrectly.
2. The router is overloaded with the number of consumers.
3. Phone malfunction.
4. Failure of the router.
5. DHCP is disabled.

We connect to wi-fi on the phone: enter the password correctly

If a password is required to connect to the hotspot, you are probably 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. Refine the combination case-sensitively and try again.

The router is overloaded: try to connect later

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

Failed to connect to the Wi-Fi network: restart the phone

Often, the phone is not able to connect to the Wi-Fi network due to a system failure in the firmware. As a result, the 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 happen 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 is also solved by rebooting. If after a while the problems reappear, you should think about cooling, or replacing the router.

Checking the router settings

A connection error can also occur if the DHCP protocol 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 in order to exclude hardware failure.

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 malfunctions, then the question arises: why does the phone not connect to 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“Disconnected” 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, possible options 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 connect the outlet after a second, but unplug the router's power cable for 10 seconds and only then plug it back in.

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 may indicate 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 Wireless operation mode / speed in the router settings, since the phone cannot always support the router operation 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 have activated this function in the router and did not specify which MAC and IP addresses can be connected 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:

In this article, we will consider a situation that many users face. You click on the icon wireless networks in the lower right corner of the desktop, select the desired network from the list, click Connect, but instead of accessing the Internet, an error appears: "Windows could not connect to ...".

There are several reasons why this window may appear. We will consider some of them in this article, and we will figure out why Wi-Fi may not be connected on a laptop.

Network Diagnostics

Let's start with the settings in the operating system.

Perform network diagnostics. We click on the wireless network icon in the tray, select the one you need and click "Connection". Enter the password if it is secure.

When an error window appears, click on the button "Troubleshooting". Windows will search for problems and suggest solutions. Just follow the guidelines. In some cases, this helps and the laptop successfully connects to Wi-Fi.

New network connection

If the laptop still does not connect to Wi-Fi, then we will delete the network to which we want to connect and reconnect. This can help if you, or someone else, has recently changed your network password. The laptop has other settings saved that do not match the current ones, which is why it does not connect to Wi-Fi.

Right click on the network icon and select "Network and Sharing Center".

In the list, select the network that the laptop cannot connect to, right-click on it and select "Delete network".

After that, again click on the network icon in the tray and connect to the desired WiFi networks. You may need to find out and enter the current password from it. After that, Internet access should appear.

Changing router settings

Let's go to the router settings. They could go astray, for whatever reason, or someone replaced them. Since you do not have access to the network in your laptop, open your favorite browser on a computer that is connected to the same router with a cable and enter the IP address in the address bar: 192.168.1.1 or 192.168.0.1.

Data cleansing

route -f
ipconfig /flushdns
netsh int ip reset
netsh int ipv4 reset
netsh int tcp reset
netsh winsock reset

Press "Enter" after each. This will help clear data in DNS and Winsock, reset route and network adapter settings.

That's all. I hope at least one of the above methods helped you. And now you will know what to do if the laptop sees the Wi-Fi network, but cannot connect to it, as a result of which an error window appears.
