A large number of subscribers using mobile communications, quite often ask questions about network problems, one of which is: “Why does the phone not see WiFi?” Now it is impossible to imagine that any of the mobile devices was left without access to the Internet using this network. It is also natural that even at home users have a home WiFi network.
Why mobile devices do not see WiFi?
WiFi network is currently considered very convenient, affordable and mobile in almost all corners of the globe. She has many other advantages. For example, you can see pretty decent savings on installing, deploying and expanding the Internet. In addition, WiFi-connection fully guarantees the compatibility of a number of equipment of various orientations and many mobile users at the same time in the same coverage area. But, unfortunately, not all users of mobile devices have a chance to use this type of communication. And, of course, they beg the question: "Why the phone does not see WiFi?"
Solving Network Visibility
Naturally, first you need to determine the reason why the phone stopped seeing home WiFi, that is, check if there is a connection at all. To do this, you can perform simple manipulations, for example, see if there is a connection to WiFi from other types of mobile devices. You also need to restart the adapter.
Possible reasons why the phone does not see WiFi can be as follows: the user’s mobile device must have the appropriate equipment - a special chip. Also, a large number of users, surprisingly, are not able to independently configure this network.
To solve the problem why the phone does not see WiFi, first you need to look at the settings of the router itself. Typically, a WiFi router automatically selects a given access point (channel). A large number of mobile phones begin to experience small problems when this same channel is above 12. You should change the channel itself in the router settings to a value from 1 to 9, reboot the device and try to connect to the network. Naturally, one should not forget about the settings and the mobile phone itself.
And if everything is configured correctly, you need to check the operation of the router and the mobile device. You can also connect to check somewhere in a free access point. And if the phone sees the network, then most likely the WiFi problem is in the home router.
Network connectivity issue on Lenovo phones
Very often, users of phones such as Lenovo also have network connectivity issues. There is a problem that the Lenovo phone does not see WiFi. In the device itself, it is possible to work on channels 1 to 11. Often, the router is tuned to a channel above 12, it turns out that there is an incompatibility between the mobile device and the router. If for other mobile devices changing the channel helps, then Lenovo needs to perform other actions.
First you need to find the build.prop file in the phone and replace the ro.wifi.channels line with ro.wifi.channels = 14 in it. Such a manipulation can be performed directly on the computer in any text editor, transferring the original file via USB. After that, you need to restart both the phone and the router. After all these actions, the mobile device should see the network.
WiFi programs for the phone
In order to use all the capabilities of their mobile phone when connected to the network, use numerous software. Now there is a large selection of WiFi programs for the phone. Such applications serve to make a WiFi access point from a mobile device. The main thing is to choose a good and inexpensive mobile Internet traffic, because, in principle, the mobile device will turn into a gateway between 3G and Wi-Fi network. And this will allow the device to connect to the world wide web. Programs are divided by type of mobile phone platform, the most popular are Android, iOS, Windows Phone.
Android-based WiFi programs: WiFi Tether and WiFi HotSpo
Nowadays, all multifunctional telephones used to access the network, social services or communicate on the Internet, almost become unnecessary if the phone has stopped seeing WiFi. When solving this problem, many realized that WiFi Tether for Root Users is considered a very easy-to-use program for the phone. The only thing that it is not so popular with users is that it requires Root access rights, but it pays off with easily accessible functions and ease of use. By default, this program sets the WiFi point in open mode, connected without a password. Therefore, before using this program, accordingly, you need to select the encryption protocol and specify the key for connecting the network.
Another WiFi program for the phone is WiFi HotSpo. It is also easy to use, but it has much less functions than in WiFi Tether, but when using this program, the mobile phone does not need to be “rutted” in advance. And what makes this app attractive is that it has a feature like USB Tethering. It allows you to use the phone as a wired modem when it is connected via USB to a computer.
IOS-based WiFi programs
Unlike programs for the Android platform, such utilities for iOS are not so common. But still there is a good WiFi program for an iOS phone, and this is MyWi. This application allows you to make a modem from a mobile device. But to make this possible, Apple devices must first be "unlocked." The application has a very good monitoring ability. And if suddenly a connection is not established, or if it works with interference, MyWi has the ability to select another channel. The only negative of it is that it is paid.
Program for Windows Phone
In one of the first versions of phones based on the Windows Phone operating system, tethering was impossible. But in subsequent models of mobile devices, this option was built into the system itself. It can be locked, depending on which specific phone model is used. The maximum connection to a network access point with active tethering is no more than five other mobile devices.
The problem of connecting mobile devices to the network and its solution
It is widely believed that quite soon the WiFi network may replace one of the available connections - mobile. But this raises one problem. The impossibility of roaming on a global scale still remains. After all, this network currently has a small radius of action. And there are problems in the form that the phone does not connect to WiFi.
Nowadays, this network is already quite common everywhere. One of the first phones with network support began to produce such developers as Samsung, Zyxel, Hitachi. Also, some time later, other phones began to develop such phones.
To date, the communication standard is probably considered the most inexpensive, and many providers provide these services for free. But it is not always possible to take advantage of the wireless network, and sometimes the question arises of what to do if the phone does not connect to WiFi.
It happens that a mobile device sees the network itself, but does not want to connect to it. Especially this often happens when the phone does not see home WiFi. If in public places where they provide a network, there were no such problems before, often the solution lies not in the phone itself, but in the home router, in its settings.
When solving such a problem, it is not necessary to turn to professionals, you can fix everything yourself. To do this, go to the device settings and change them. This can be done using any internet browser. Right in the address bar you need to dial the IP router. These are the notations: 192.168.1.0 and 192.168.1.1. Next, you need to find the DHCP section and check the Enabled section, in other sections - Default Gateway and Primary DNS - you need to enter the IP of the router.
Thus, if all the actions are performed correctly, then the question of why the phone does not connect to WiFi should be resolved. This method helps to protect data exchange, that is, it makes it possible to set a password for a network connection. Only users who are allowed to connect to it will be connected.
