The phone sees Wi-Fi but does not connect
The phone does not connect to Wi-Fi: Causes and Solution [Android]
Today, Wi-Fi nets are entangled almost everything and everywhere: residential buildings, parks, airports, hotels, and t.D. And while the mobile Internet is still not cheap and affordable, one way or another when using the phone you have to connect to these Wi-Fi networks.
The tarpting spoon is that approximately every 10th connection from the phone ends in failure.
Actually, that’s why I decided to “focus” the topic of today’s article on this issue (all the more there are many questions about it). I note that I will touch in the article those devices that operate Android (Android).
By the way, many people complain at too small the time of the phone from the battery.
If you want to know why the battery can quickly sit, eliminate these reasons and increase the battery life of the smartphone, I recommend this note
The Internet was missing on a smartphone, although he used to work
Let’s start with the last. Before moving on to more complex manipulations on your phone, try to reload it. Very often, as a result of continuous work, small errors arise in the system, which as a result lead to the fact that the Internet stops working. This applies to any operating system (Andorid or iOS) and does not depend on the brand, whether it is samsung, Xiaomi, Huawei, Honor, iPhone or any other. After restarting the system, many of them are corrected, and the Internet can earn again.
Incorrect date and time in the system
Another situation in which often on the phone is a mistake about the inability to reach the Internet is a failure in the dates and time settings
Despite the fact that any modern mobile operating system has sufficiently built.In means to protect the user’s personal data, many still continue to install antiviruses, firewalls and other applications from third.Party developers that block certain actions on their smartphone.
Very often, individual sites or entire browsers become the victim of their work, as a result of which it seems that the Internet does not work, although there is a network connection to the network. If you recently installed a similar application, then delete it or set the settings so that it does not block the network.
As an extreme measure, you can make a complete reset of smartphone settings. On Android you can do this from the menu “Extended settings. Restoration and reset”.
In this case, he will return to the factory state. And if there are no breakdowns directly in the components of the phone (for example, a wireless model has been covered), then the Internet should earn again. However, this is the last technique to apply. But first I recommend checking the items from the list below.
Reasons why the Internet does not work via wi-fi on Android
Whoever said, but Android also has different “glitches” and errors. Therefore, the first thing to recommend is just to restart the device (for this, hold the power button for a few seconds, then a window appears that has a restart option (RESTART, see. Screenshot below)).
Even if you have not flew anywhere, this option can be turned on (or work wrong). Check that it is turned off. In addition, try to turn it on and then turn it off again.
Try disconnecting and turning on the Wi-Fi network again.
If this does not help, I also recommend deleting the created Wi-Fi connection (in the section of wireless networks), and then re-connect. Cm. Screen below.
By the way, when the problem is connected over time, the Wi-Fi icon becomes gray (what icons on the phone screen can be).
Pay attention not only to the time itself, but also on the date, the time zone. Carefully check the time format (it is recommended to use the 24.Hour format), date format. Often due to incorrect entered data. There are problems with the network.
5) Internet blocking with protective applications, antiviruses

If you have antiviruses and others on your smartphone (tablet). Protective utilities. Try to turn them off for a while. The fact is that many modern antiviruses have a module for checking Wi-Fi work, and in some cases they can block the normal operation of the network.
In general, this advice is rather, as excluding, t.E. Check just in case. The fact is that if you did not indicate by hand (yourself) the proxy server, then most likely, you have everything normal with this parameter.
So, go to Wi-Fi settings, click on your network and select the “Change network” option. Next, put a box at the “Extended settings” item (may be called “additional”, depending on the device). And check that in the “proxy server” column “no”.
If you have something excellent there, then translate into “no” and save the settings. Check the operation of the network.
7) IP addresses in the connection settings are incorrectly set
In the same tab, check that in the “IP settings” column there is a “DHCP” option (example on the screen below).
8) the problem with DNS servers (approx.: DNS from your provider could “fall off”)
A small certificate!
When you open a page in the browser, then your device first sends a request to the DNS server, asking him on which IP address is such and such a site. DNS server returns the IP address to your device and after the page is loaded after.
As a rule, by default, the DNS servers of your provider are always used (and they, as a rule, do not differ in particular stability and speed).
So, if in the connection settings to be forcibly change the DNS server, in some cases it is possible to “return” the Internet to normal. Mode.
You can do this on Android, if you open the extended Wi-Fi connection settings, transfer the IP settings item to the user mode, and indicate 8, respectively, 8, 2 lines.Eight.Eight.8 and 8.Eight.4.4 (DNS from Google).
Save the settings and check the Internet of the Internet.

9) In the settings of the router are restrictions
In this article I did not want to touch the router settings, but I can’t help but note that in modern devices there may be special. Access restriction settings. For example, there may be a “white” list: t.E. It is allowed to enter the Internet only to certain devices.
For example, in Tenda routers in the “Passing Strips” section, you can not only limit the speed of the device to the Internet, but completely disconnect them from it! Cm. Screen below.
Router Tenda. Braps control of the strip
If you do not know if you have restrictions on the router. You can try to reset its settings and return them to the factory pre.Installations (. : If you do not know how to configure the router after reset, then it is better to refrain from this operation).
The last thing I can recommend (as an extreme measure) is to try to make a complete reset of the smartphone/tablet settings (original name “Hard Reset”).
This option is available in the Android settings, in the “Restoration and Reset” section (recovery to factory settings). But teach that many data and parameters will be lost! Therefore, first save from the device everything that can be of value.
Wi-Fi is turned off on a laptop, so he does not see nets from a router or phone
First of all, it is necessary to exclude the most banal “malfunction”. Many newcomers simply do not know how to turn on Wi-Fi on his laptop, so he does not see a single wireless network. Modern devices are usually built in a wireless adapter. By default, it can be disconnected.
In different models, Wi-Fi can be included in its own way.
For example, a separate button on the case indicated by the corresponding icon
Finally, the module can be activated directly from the Windows system. To do this, you need to go to the “Control Panel Network and the Internet Center for Control of Networks and the General Access of Changing the Adapter Parameters”
And activate the “Wireless Network” item

Also check if your laptop is in the aircraft mode (“Square on the aircraft”). This function is present in Windows 10, when all wireless connections are disabled, and the laptop does not see either the Wi-Fi network or Bluetooth devices. You can turn it off either a special button from the keyboard
Or press the Windows 10 icons on the icon in the form of a message and deactivate the mode so that this menu item is not allocated.
A sign that Bluetooth on the laptop will work will be Wi-Fi icon on the lower Windows panel next to the clock.
The main reasons why Android is not connected to a Wi-Fi router
I will list the most popular reasons for errors when connecting an android to a Wi-Fi network:
Delete the network settings
Now in detail about each item on the example of a Xiaomi smartphone. The first thing I immediately do if the phone does not connect to Wi-Fi is a complete discharge of network settings. This does not require removal of any settings. It is enough just go into the parameters of the current Wi-Fi connection
And click on “Delete this network” at the very bottom of the screen.
Then connect the smartphone to the router with standard Android means with password entering.
Static IP address
If this action did not help, then I propose to manually set a static IP address to connect your phone with a router.
On Android, this is done almost the same in all versions of the system-we go into “Wi-Fi Settings”, we see our active connection to the network and click on the arrow.
Next, it will be necessary to squeeze the page to the very bottom to the drop.Down menu “IP Settings” and change DHCP to “User”. Additional forms for entering the parameters will open.
- IP for the phone from the address of addresses specified in the router and available for use. If the address of the router 192.168.One.1, then for the phone you can assign 192.168.One.45, for example.
- Subnet mask. 255.255.255.0
- The router is an IP router. In most models, by default, he has an address or 192.168.One.1, or 192.168.0.1. Try them, if it doesn’t work out, then contact the network administrator.
- DNS is also an IP router, or you can use one of the Google public addresses. 8.Eight.Eight.8 or 8.Eight.4.4.
Why does the phone not see the Wi-Fi network
The problems affecting the display of access points are conditionally related to problems:
To eliminate problems with displaying Wi-Fi networks, it is necessary to correctly diagnose the problem. To identify the cause, the best way is to connect another mobile device. If the second smartphone also does not see a wireless network, then the problems are connected with the router or incorrect settings. To clarify the latter, it will better connect to another access point.
We connect to Wi-Fi on the phone: We enter the password correctly
If a password is required to connect to the access point, you probably enter a wrong combination. The security key is sensitive to the register. Therefore, if the password includes capital letters, then writing the right combination, but in small letters, will not work. Check the combination taking into account the register and repeat the attempt.
Public networks requiring a password or allowing free connection are always overloaded with an extensive number of connections. As a result, the router is not able to accept new users due to the load of the channel. Solution. Repeat the connection later or use another access point.
What can be done if Android does not see Wi-Fi network
Sometimes, due to various errors, it can become so that the router (for example) ceases to distribute the Internet. Therefore, one of the very first tips in this case is to reboot the router (for this it is enough to turn off its power supply from the network for 20-30 seconds.).
After I would also recommend rebooting the phone (RESTART). To do this, just clamp the power button on the Nesk. Seconds (see. Screenshot below).
2) which channel (region, if any) is selected in Wi-Fi settings
Each of the radio devices works at a certain frequency (and the router is no exception). So, the channel (region) affects the frequency in the settings of the router. And I immediately note that different countries use different number of channels: in Russia from 1 to 13, in the USA to 11, in Japan up to 14.
The bottom line is that if your device is localized to work in another country, then it may not see some channels. Say, if your phone sees only 1 to 11 channel, and the auto-mode is selected in the router settings (and it chose the 13th channel)-then your phone simply will not be able to work with such a Wi-Fi network.
The channel and the region are set in the wireless network settings (Wireless) in the web-integrator of the router (see. A couple of screenshots below).
1) How to go to the router settings. See. Instructions.
2) how to choose the “best” channel for work (instruction) how to change it in the settings of the router.
Wireless network settings. Router Tenda
Wireless mode. Settings (TP-Link router)
Now most classic routers are working at a frequency of 2.4 GHZ, but recently new routers with a 2nd frequency have appeared on sale: 2.4 GHZ and 5 GHZ (5 GHZ allows you to unload 2.4 GHZ, and improve the quality of Wi- FI network in houses where too many routers work at a frequency of 2.4 GHZ).
But here the whole point is that not all laptops, tablets, phones support 5 GHz frequency. Pay attention to it also!

3) Does the phone sees the Wi-Fi network at all (at least some?)
If the above did not help, pay attention to the phone: does he see any other Wi-Fi networks?
If the phone does not see a single Wi-Fi network at all (although other devices are found)-perhaps he has a hardware problem (he could become unusable of a Wi-Fi module). I recommend rebooting the phone, remove the cover from it and try to find Wi-Fi again. If it doesn’t work out, contact the service center.
If the phone is generally sees a Wi-Fi network. But it does not find only one specifically yours. Then pay attention to the channel and the region (this was indicated just above ☝), the coating area (perhaps you are too far from the router and the signal in this place is weak), for some parameters of the router (slightly about them below ).
4) Does the Wi-Fi router with the Wi-Fi network (whether other devices see it?)
Next, I recommend checking whether the Wi-Fi network (which you want to find on the phone) see other devices, for example, a laptop or tablet.
It is possible that the problem is still in the settings of the router. For example, the router settings could take a reset (this sometimes happens with electricity.
Check that the wireless network is enabled
Another important point: a “white” list (blocking of unknown devices can be in the router, is usually carried out according to the MAC address).
This is done for security purposes so that “unknown” devices cannot connect to the Wi-Fi network. Therefore, pay attention to the tabs “Safety”, “Parental Control”, “Control of the Passing Strips”, “Setting the Wireless Network” in the web-integse of your router.
In some cases, it is easier and faster to lose the settings of the router to restore factory pre.Installations (they usually have no blocking and restrictions).
Pay attention to the location of the router. The fact is that the quality of the signal and the Wi-Fi coating radius depends very much on where the router is located and where the receiving device (each “extra” concrete wall or other obstacle greatly reduces the signal). And if, the phone is behind two concrete walls from the router, it is quite possible that he will not find this network.
Recommendation: Remove the cover from the phone, reboot it, and bring it closer to the router (within a radius of 2 ÷ 3 m.). Check if there is a network.
The location of the router in the apartment: right. The option is much more successful
6) if you are distributing a Wi-Fi network from a laptop
If you distribute a Wi-Fi network from a laptop, then in some cases you need to make some settings at the Windows networks center (the fact is that security settings in Windows 7 by default can block the Internet for other. Devices).
First you need to open the Windows control panel, and go to the tab: the control panel \ network and Internet \ Center for Network Management and General Access.
Next, open the link in the menu on the left “Change the additional parameters of the general access” (see. Screenshot below).
Networks control center and total access
