Phone doesn‘t see Wi-Fi. what to do

If there is no access to the wireless network from your smartphone, then the problem may be related to the router or smartphone. Sometimes it can be a malfunction, in other cases the cause may be the wrong settings. When problems arise, you need to determine where exactly the cause may be.

There are usually devices in the house that get internet from a router. If only the smartphone does not have access, then it is an indication that the router is faulty, and you need to check the phone to find errors. If there is no internet on either of them, then the likely cause is the router.

To solve the problem you need to check the probable causes. In most cases, access can be restored by your own efforts.

Problems with the router

It is necessary to make sure that the router is connected to the mains. The wire should be inspected from both the socket side and the device side. Since the connection is made through an adapter, you can not exclude its fault. It is necessary to inspect it and make sure that there are no visible damages. To check it, you can test on a similar device, if possible.


There are several indicator lights on the router. One of them is responsible for the wireless signal. Check to see if the indicator light is on. The number and location of indicators may vary from model to model.

Sometimes the device has a button to enable or disable WI-FI. If it is available, you need to make sure that it is in the right position.

To find the reason for the lack of access, it is useful to make sure that the router settings are correct. First of all it is necessary to check if wireless access is enabled. To do this, do the following.

  • Start any browser and go to the router IP address.
  • Enter the password and login to access the settings.
  • Go to “Wireless” section.
  • Check whether the “Enable wireless router radio” box is checked. If it is not there, then you need to set it up.
  • Confirm the entry and exit the settings.

After that you need to check whether the wireless network is working.

If the router does not turn on, the lights are off, it is possible that the device is defective. Sometimes in this situation can help to reflash. If this does not help, you will have to contact the service for repair.

It can be a situation where access has disappeared because the power grid has lost current. You can easily miss it in the daytime. The only solution is to wait until the power comes back on.

If a simple network name is used, it may be the same as another. In this case it will not be possible to identify when logging in. In such a situation you need to change the name on the router. This is also required on all connected devices.

The router may have restrictions on how many devices can be connected. If more devices are used in practice, it will lead to communication interruptions. It is necessary to set such a parameter which corresponds to the actual situation.

There may be lockouts in your router’s settings. When checking you should pay attention to the following tabs:

Restrictions are set in relation to the MAC addresses of the devices.

DHCP must be enabled in the router. This feature allows you to distribute network addresses among the connected devices. If it is disabled, it will not be possible to connect to the router. To check this and correct it if necessary, you need to do the following:

  • Start the browser, type in IP address and go to settings.
  • Enter login and password, go to main page.
  • Go to LAN tab or similar. Names can be different for different router models. You must set the “Allow DHCP” option.

If necessary, you can adjust the parameters of this function.

Phone problems

The smartphone has the ability to set the “flight mode”. It completely blocks wireless connection. The only exception is using GPS receiver. Make sure that this mode is disabled.

Problems can occur when infected with computer viruses or overloading the system with various applications. In this case it is recommended to reflash the phone. To prevent this from happening, it is recommended to use anti-virus software. Although you can install a large number of applications on your phone, you must be careful to select those that are really needed.

If the wireless module has stopped working, it must be replaced. In this case it is necessary to address to the specialists of the service center for repair.

Incompatibility between smartphone and router

Sometimes the network settings on your router and your phone are so different that they make it impossible to connect. To check this, you need to look at the settings of the devices and compare them. If there are differences, you need to eliminate them.

When analyzing, it is necessary to pay attention to the following:

  • Encryption is used when going online. It is necessary so that unauthorized persons could not get access to confidential information. You can choose from several encryption methods. If the smartphone and the router settings use different methods, then the connection between them will not be established. You need to adjust the settings so that the router and the devices connected to it use the same encryption methods.
  • Devices can use two frequency bands: 2.4 GHz and 5.0 GHz. The first is more common, but technically less advanced than the second. You need both devices to use a common band. If the device can work with the 5.0 GHz band, that means it supports Wi-Fi 02.11AC or Dual Band.
  • Sometimes a connection failure can occur when the date and time do not match. Because of the impossibility of matching, communication between devices is interrupted.

Why does Wi-Fi not work on your phone after updating your system

After updating the system, very often there are situations when the phone does not want to connect to certain access points. And it works selectively. Sometimes there is no connection to home networks, and after some updates to public and work networks.

often than not, it has to do with updating data. When an Android or iOS software update occurs, the phone almost always resets some of the previous data in order to install the new software. Including data about previous networks, connection algorithms and passwords.

This is a fairly common problem. It does not indicate that there is anything wrong with the device. In fact, many people experience similar problems from time to time after an update. There is no need for you to go to the diagnostics department. You can either wait for update fixes or fix it yourself.

Fixing the problem

It is possible to cope with the problem only if you identify the exact cause of the problem. It is not always necessary to go to a specialist for this. Many errors that concern, for example, the parameters of wireless mode, you can identify yourself. If the Internet slows down, works slowly, this can be caused by other factors: for example, network congestion, when many gadgets are connected to it. Sometimes slow Wi-Fi is an occasion to check the computer itself, or a line for the trimmer connection of your Internet provider.

First of all, you should pay attention to how the Wi-Fi access point is set up. This requires access to the router menu through the browser: but you will need to enter a number of characters into the address bar, the combination of which is individual for each device. Usually these data are situated at the back side of the router. look for the Login and Password, you will need them at the next step.

Enter user name and password. If you have managed to get access to the menu, first of all you should pay attention to the wireless mode parameters. A few simple options are relevant here:

  • Channel. Auto, but you can try another channel.
  • Mode. 11 bg Mixed, but changing the parameter to 11 bg only might give a positive result.
  • Channel Width. auto.
  • The baud rate, if any, is set to maximum.
  • Region has little effect, but can theoretically be source of malfunction.

If everything is set correctly but the Internet does not work properly, you should contact a service center or look for the problem in another place, for example your ISP. The device may be technically defective, so it is recommended to check it immediately after purchase.

Checking Wi-Fi operation in Android smartphones and tablets

Though tablets and smartphones, in contrast to PC and notebooks, where the Wi-Fi module is often removable/external, don’t require complex diagnostics, the problem can hide in the gadget itself, and not just in the router and/or modems (if you have an ADSL/ONT-modem or 3G/4G USB-modem together with the router). This is true for the Apple iPhone/iPad/iPod/Watch below, as well as for older gadgets based on Symbian, BlackberryOS, PalmOS and their other modern counterparts.

Check connection to known network in Android

First, give the command “Settings. Wireless Networks” and check if the flight mode is set. in this mode all radio transmitters of the gadget (except for GPS receiver) are blocked.

Unlocked MTC-916 (ZTE Racer) and its Wi-Fi settings

Go to Wi-Fi settings and choose a network, the key of which you know (for example, your ZTE MF90 router or similar). All routers (and gadgets/PCs working in Wi-Fi transmitter mode) that you’ve connected to) are signed as known networks.

If there is no connection, the main reason is incorrect password from Wi-Fi network, with which the gadget saved this network in the list of known. Give the command “Network Information” (by pressing the menu button under the visible part of the sensor). “Delete”, then reconnect to the same network.

Delete the settings for your router, then enter them again

Another reason may be the device freezes due to a virus or adware, causing an overload of the processor and RAM in the gadget. Unlike iPhones and other Apple gadgets, which are reliably protected against such tampering, Android devices are reflashed for this very reason. when they freeze, they lose all control, including the submenu with Wi-Fi settings.

Restarting the Android device

If your Android smartphone or tablet is so hung up that it’s no longer controllable, and isn’t even able to restart its built-in Wi-Fi module, you can try restarting it from the power button by giving the “Restart” command. In recent versions, if performance problems are detected, the Android operating system restarts automatically.

Reboot (Restart) in the Android power off menu

Try also to call a hung up smartphone. If your battery level was low before the hang-up, wait until the battery is fully discharged, calling the hung-up gadget over and over again if you hear ringing tones. it happens that the 3G terminal in your smartphone receives calls and SMS, but the screen stays with a hanging backlight, or is turned off. In case of the call failure (clicks and answer “Caller is unavailable” after one or several dialing attempts) remove the back cover, take off and insert the battery, switch the smartphone on. If your smartphone does not start, contact the service center or try to flash the gadget yourself (if you are confident in your actions and have the necessary knowledge).

Resetting the Android-gadget

New reconfiguration starts with a reset of user data and OS settings. It is recommended to remove the SD-card to avoid losing valuable files from the SD-card. Depending on the model of the gadget, the slot for microSD-cards is located next to the SIM-cards and/or a hidden “Reset” button.

    Give the command “Settings. Restore and reset. Reset settings. Reset phone/tablet settings”.

Press the reset button to reset your data and Android settings

Disk C: (gadget’s flash memory) will be emptied (Android user folders).

It is possible that full reset of Android will remove Root-access, i.e. “administrator” privileges of your gadget, that are implemented by third-party applications like KingRoot. You will lose full access to Android system processes, services and hidden (including system libraries and drivers) folders and files. When you set it up again, Root rights will need to be set anew.

  • Go to the familiar Wi-Fi submenu and reconnect to any network you know.
  • Once the internet is available, go to Google Play and reinstall the apps you previously used.

The Internet over Wi-Fi is evidenced by Android’s attempts by background services to update pre-installed programs (these updates are enabled by default) and to send Google some information about the gadget.

The problem with Wi-Fi connection on the router side

You can restart your router, reconfigure it after resetting, change additional Wi-Fi settings, check your device MAC filtering settings, etc. д. As an example, let’s take the Asus RT series routers.

Restarting a router

Asus RTxxxx routers can be restarted using the restart button on the main page of the web interface.

The Asus-RT restart button is at the top of the web interface home page

Confirm the request (if any). The router can also be restarted by pressing the reset button (on/off, depending on the brand and model) or by turning off its power for a few seconds.

Resetting and reconfiguring your router

Resetting and reconfiguring your router can help, for instance, if you suspect a virus may have changed your settings.

    Perform a reset of the settings using the “Administration. Manage Settings. Restore” command.

The button to reset your router to factory settings is located in the “Administration” section of the web interface

To configure the Internet connection, enter all the data provided by your ISP

To put a router in the access point mode, you need to select it in the menu “Administration. operating modes”

It is necessary to specify the address of the device in the network, router address and specify the IP DNS-servers

Assign a strong WPA-2 password to the Wi-Fi network

Turn on and configure the DHCP server on the router

Your iPhone or Android smartphone will go online after connecting via Wi-Fi.

Changing the Wi-Fi channel settings

Channel width of 40 MHz instead of 20 MHz can reduce the number of simultaneously working devices by 2-3 times. Not all of them support 40-megahertz band. it’s mainly a prerogative of router networks (chains of routers when creating a coverage area of any length with shared network access). The smartphone or tablet, even when operating in repeater or access point mode, does not use a single 40 MHz band, but two separate 20 MHz bands.

For instance, in TP-Link routers the Wi-Fi environment parameters are configured via the “Wireless Networks. Wireless Setup” command.

In the wireless settings you can change the speed, width and channel number of the Wi-Fi

The width and number of the channel, as well as the Wi-Fi speed mixer, ultimately determines how stable the router will work

Managing MAC filtering

Filtering by MAC-address is used for maximum security (hidden network without SSID in the air, avoiding “foreign” gadgets and PCs). Normal users simply disable it.

If you do not use MAC-address filtering check that this mode is turned off, otherwise it can cause a lack of communication via Wi-Fi

Wi-Fi restoration is not a problem even for those, who just yesterday bought their first router and gadget. Even checking the router settings does not cause difficulties. the manufacturers are trying to make the process of managing the device as accessible and understandable as possible. Have a great speed online!

Why phone does not see the WI-FI network

Problems affecting the mapping of access points are conventionally related to malfunctions:

To troubleshoot problems with Wi-Fi network mapping, you need to properly diagnose the problem. To identify the cause, the best way is to connect another mobile device. If the second smartphone also can not see the wireless network, then the problem is related to the router or incorrect settings. To clarify the latter, it is better to connect to another access point.

How to connect your phone to a public Wi-Fi network

Open public networks are sometimes a real salvation, when the phone suddenly declares a boycott to the mobile Internet and stubbornly draws an icon EDGE, putting an end to the plans to surf the social networks, watch movies, read the news. In this case it is worth looking for an available and free WI-FI networks. They are in all airports, most restaurants and cafes, train stations and parks, and even the subway. not just. To connect to such a network, you just need to choose the option with the largest number of “sticks”, showing the signal strength. Networks are divided into public and password-protected. In the second case, you can ask the staff for the passphrase, if, of course, this network is intended for visitors.

For your phone at home to be able to connect to the wireless network, you need a router. In his role can be a laptop or computer with a WI-FI adapter. Top tip: do not be lazy to put a quality password on the network and connect the security type WPA2. Do not try to be a good neighbor, it is fraught with many problems from running out of traffic to problems with the law, if your network is connected to the wrong person.

It is enough to set up a connection once, then the phone will automatically find the home network.

Error search, if the phone does not see Wi-Fi in the room

It is important for the user to clarify what problem caused the specified situation:

  • Completely no connection to the virtual line. after saying “saved” and getting a permanent IP address it gives errors of authentication, authentication. Also it may report incorrect password, etc.
  • Communication with the router is there, but the Internet does not function. an exclamation mark is lit near the line label, a message about the inaccessibility of the World Wide Web or the smartphone does not log in through the browser or app.

Specialists recommend recollecting what caused the initial malfunction. Sometimes failures are associated with changes in settings of the router or smartphone, connection of new devices, installation of software. Only when the root cause is found can the problem be easily fixed.

Regardless of the inscription on the gadget and the connection to the home or public network, you should try the following actions to remedy the situation:

  • Stop and reactivate Wi-Fi or reboot it;
  • Restart the adapter by turning off the power for 3-5 minutes and turning it on again;
  • reconnect to another line.

If the issue is related to public Wi-Fi, there is a risk that the point temporarily does not work or does not withstand a large number of clients, which leads to the fact that a particular device starts to stop catching the signal.

What to do if nothing helps

If none of the above methods helped you to eliminate the problem, then try to find the cause in the router itself or contact the technical support of the operator, there is a chance that the error occurs on their side. If you are sure that the reason is in the device itself, there is only one thing left. to reset the settings to the factory settings. Please note that resetting will lead to the loss of all data stored in the memory of the device, so save them on other media. To perform a reset, go to the “Restore and reset” block in the device settings, and then click on the “Reset” button and go through the procedure.

We press the “Reset” button and complete the process

If Android connects to Wi-Fi, but does not download anything through this network, you need to restart the router, the device, reconnect, change the IP and DNS settings. The surest, yet most radical method is to reset the settings. If that doesn‘t work, the Wi-Fi module is broken.
