Wi-Fi doesn't work on iPhone - let's look into the reasons. Wi-Fi button is gray and inactive - what happened to the iPhone? Wifi doesn't work on iPhone 7

Using wireless Internet is one of the important advantages of modern smartphones, so when problems arise with the Wi-Fi connection, each of us experiences discomfort. Unfortunately, cases when iPhone 7 loses Wi-Fi are not so rare and it is important for the user to know how to behave in this unpleasant situation.

Restarting the device

Like many other problems, losing your Wi-Fi network can be resolved by rebooting your smartphone. In this case, the method of reboot is not important - if the problem is a failure software, then there is a high probability that everything will fall into place. If after turning on iPhone 7 found the network, then there is no point in even figuring out why the Wi-Fi connection did not work - such failures, alas, happen even with iOS 10.

Connection refused

If the first method was not effective, then you can try to “forget” the Wi-Fi network and try to connect to it after the iPhone finds it as new. In order to do this, you need to go to the settings menu Smartphone Wi-Fi, find the problematic network and refuse to connect to it. After that, you can try to connect again, using it as a newly discovered one.

Disabling a system service

Very often, in a situation where the iPhone loses the Wi-Fi network, disabling the corresponding service helps. To do this, go to the “Privacy” menu and select the “System Services” item there, located in the “Location Services” submenu. Disabling and re-enabling the Wi-Fi service after a few minutes often resolves the issue.

Reset

A full reset can be effective if you experience constant crashes. Wi-Fi networks. Reset is done in the menu iPhone settings Settings - General - Reset.

DNS change

Change DNS server on OpenDNS or GoogleDNS very often helps to establish a stable connection to the point Wi-Fi access. You can make these changes in the settings menu of your smartphone.

Full reset iPhone 7

Resetting the settings is the most radical way to return normal operation of Wi-Fi without resorting to the help of specialists. You can use the iTunes app to reset.

If iPhone keeps losing Wi-Fi and none of the above methods helped, then most likely only a specialist can help you service center. It is quite possible that the cause of connection failures has to do with the hardware.

Users of all generations of IPhone eventually encounter problems recognizing Wi-Fi networks. Let's take a closer look at why Wi-Fi doesn't work on an iPhone and how to fix this problem yourself.

Before you fix the problem on your IPhone, make sure your router is working properly. Connect to it from another device. Also try restarting your router and trying to connect to it again. Make sure you enter the correct password.

We update iOS

Unstable work wireless network may be a consequence of using outdated version IOS. To check your phone for available updates, go to Settings-General and then click on Software Update. This method updates involve downloading new version firmware “over the air”, that is, this requires a working connection to the Internet (for example, to a 3G network if there is no Wi-Fi).

Also, users can update the firmware using iTunes. Connect your phone to your computer. The “Overview” tab in iTunes displays all basic information about the device (model, phone number, firmware version, etc.). To check for updates and install them, click on the “Update” button.

Use this method if your phone has recently been finding and connecting to Wi-Fi networks, but the connection speed is very slow.

Resetting Wi-Fi network settings

Often Wi-Fi does not work due to incorrect settings. Perform a reset by clicking on the icon to the right of the access point name in the Wi-Fi window. In the list that appears available options select Forget Network. Then turn off Wi-Fi, restart your phone and try to detect the network again.

Disable Wi-Fi in the System Services window. Select Settings-Privacy-Location Services. In the system services window, make sure that Wi-Fi is turned off. After this, reboot your device again.

Hard Reset

If Wi-Fi does not work on your iPhone and the networks are not displayed in the list of available access points, or the phone has connected to the network, but not a single Internet page loads, you need to do a Hard Reset - resetting your smartphone. After this, all data will be deleted from your phone; we recommend making a backup of your files and contacts.

Go to Settings-General. Select Reset and click on “Reset settings” at the bottom of the page. After this, the phone will turn off and start hard reset. The procedure may last 10-30 minutes. A hard reboot can resolve most issues. software problems in iPhone.

Hardware failure

If none Wi-Fi network is not recognized, the problem may be caused by a faulty Wi-fi module. Replace the part with a new one to eliminate the problem. The Wi-Fi module in iPhones is a chip located in the upper right part of the case. The circuit is covered with a protective panel. The figure below shows the location of the part.

The problem may be with the antenna, which works with Wi-Fi signals and Bluetooth. If these two technologies do not work simultaneously on your IPhone, change the antenna. This hardware component is a plate at the top of the smartphone. Underneath it are the cable connectors. Replacing the antenna can solve the problem of poor connection to Wi-Fi and Bluetooth networks.

Connecting to Wi-Fi is as necessary a function for a modern phone as making calls or sending SMS. Every iPhone owner sooner or later faces a problem when this function fails for some reason. This article is intended to most fully explain why Wi-Fi does not work on an iPhone and how to deal with it.

Problems with Wi-Fi on an iPhone can manifest themselves in different ways: the phone may not see the network, or it may see it but not connect. Sometimes the function icon itself in the device settings does not work.

Usually there are two groups of sources of malfunction:

1. Hardware - everything related to mechanical damage to the iPhone, burnout of modules or factory defects.
2. Software - incorrect operation of the iOS operating system or other software.

The type of failure is easy to identify if Wi-Fi stops working after the phone has been in water, dropped and overheated - this is clearly a hardware failure. On the other hand, notice, for example, short circuit while charging is almost impossible.

If the cause of the problem is not obvious, it is advisable to contact a service center, where they will help you deal with the module failure. But most often the gadget can be repaired at home. There are a few simple ways troubleshooting yourself.

Updating iOS

It often happens that the source of the failure is the incorrect operation of the software. This is especially true for firmware. Most of the errors associated with this are corrected by developers in new iOS versions, so the first thing to do is update the operating system to the latest version.

This is a fairly easy process, and will most likely solve your Wi-Fi problems.

Resetting Wi-Fi network settings

The developers also recommend trying to reset all connection settings and remove known access points and passwords for them. This is done through standard menu iOS configurations, through the “General” menu. Next, you need to select the “Reset” section and already there - “Reset Network Settings”. Your device may require you to enter your Apple ID password.

After the reset, user settings will be deleted, including passwords and saved addresses. If the connection to the wireless network is not restored after this, it makes sense to look for clues elsewhere. There are several other easy methods to restore communication.

Reconnecting to a Wi-Fi network

Among possible ways get Wi-Fi working on your smartphone - reconnect. To do this, you need to go to the Wi-Fi configuration, select an access point to which the gadget does not want to connect and set the “Forget network” command, and then start searching for distribution points. You can learn more about the problem of finding a network by going to.

If manipulations with configurations do not help wireless connection, it makes sense to do a hard reset. This will return all phone configurations to factory default. This can be done by simultaneously pressing the “Home” and “Power” keys. After such a reset, all user settings and programs will be deleted.

Rebooting the smartphone usually “cures” most Wi-Fi errors. This is the most that the user can do independently if the source of the bug is a failure in operating system iOS.

Hardware failure

The most serious problems are with the hardware. Malfunction internal components gadget is common cause Internet connection problems. It is not recommended to repair the phone yourself, especially if the Wi-Fi module is damaged. But if the failure occurs due to overheating or water ingress, you can try to fix it with a hairdryer.

To do this you need:

• Take off back cover(for model 4) or screen module (for iPhone 5 series and higher). To do this you will need a Pentalobe star screwdriver. The best option is a special screwdriver for iPhones.
• Find the module. It is located under a metal cover, which also needs to be removed. Then you need to unscrew the screw securing the antenna and very carefully remove the module. For more information about the location and the complete replacement process, see the video at the bottom of the article.
• Warm it up gently with a hairdryer. Hot air (slightly hotter than room temperature) should only get there, but not constantly “hit” one place. The procedure takes no more than two minutes.
• You only need to reassemble the device after the board has completely cooled down.

The procedure should be approached with extreme caution. There is always a risk of critical damage to smartphone components.

The problem is in the router

If the above tips do not help, there is a possibility that the router itself is not working correctly. This is easy to check - if other devices, including a computer, also cannot connect, then most likely you should pay attention to the configuration of the transmitter. They are often reset due to connection reboots and some external problems. In some cases, the reason lies in a hardware malfunction of the router.

ABOUT incorrect operation The transmitter is indicated primarily by the indicators. All of them, with the exception of the power indicator and the WLAN indicator, should blink - this indicates that the device is transmitting data. Power and WLAN should be lit steadily. Many users often simply forget to enable the latter on the router itself.

The internal configuration of the router is done through the menu, which can be accessed using an Internet browser at 192.168.1.1 or 192.168.0.1. If the user does not know the correct values ​​for setting up the connection, it is better to call a specialist or call the telecom operator’s support service.

Conclusion

Connection difficulties are quite common, and many of them can be resolved on your own. This should be done if the causes of the problems lie on the surface and are easily recognizable. And if it is possible to put the device in order without the risk of breakdown. In all other cases, it is strictly recommended to contact a service center, especially if the error is hardware. In some cases, only specialists can accurately determine the specifics of the malfunction and eliminate it.

Got an iPhone 7 or iPhone 7 Plus, and then began to notice that your new smartphone does not connect to Wi-Fi as well as you would like, and also does not provide normal data transfer speeds in WiFi networks? This problem really does exist. And, of course, the owners of the “best” iPhones can’t possibly like it.

Moreover, judging by the reviews, it is unpleasant to “stupid” and “slow down” Wi-Fi in new iPhone 7 (or vice versa, iPhone 7 in Wi-Fi) starts most often when the user launches applications of his favorite social networks, like Facebook, Instagram, Whatsapp, Twitter, etc. Pictures and icons turn gray, everything loads slowly, if at all.

So, there is an opinion that one of the main reasons why the iPhone 7 can work so poorly/slowly on a WiFi network is its weak signal, which is simply not enough for a high-quality connection of the smartphone to the Internet.

What to do?

In fact, the public has tried many ways to combat this problem. They work with varying efficiency, both individually and in combination, but the result is generally positive. Therefore, if your iPhone 7 also has problems with its WiFi connection, we recommend trying the following:

• restart your smartphone;

• activate the “Forget this network” option and then connect to it again;

• reboot the wifi router (if possible);

• reconnect the iPhone from DHCP to a static IP address (you need to create an IP that the router does not use, it will start with 192.168.1.xxx, we take the number from the very top of the router’s range so that there are no conflicts with DHCP IP addresses);

• switch to Google DNS servers;

• change throughput networks in the Wi-Fi router settings;

• change the Wi-Fi channel in the router settings;

• configure the security level in the router (if necessary, you can even disable security temporarily);

• switch to another tariff plan, which provides more high speed data transmission;

• buy a new, more modern router (here link to the website catalog of Wi-Fi routers);

• hard reset iPhone 7 ( full reset systems) if other methods have not had the desired effect.

As practice shows, in the vast majority of cases, the listed measures help solve the problem with wi-fi on the iPhone 7 (as well as on any other iPhone).

Sometimes knowledgeable users also perform the so-called “application cache clearing”. This procedure allows you to eliminate a number of glitches and malfunctions in the iPhone 7 software, including those that lead to poor-quality connections to wifi networks. Such cleaning also does not delete data from the device’s memory, that is, all photos, videos, messages and other important files remain safe and sound.

To see the state of the program cache in iPhone 7, tap: “Settings” -> “iCloud” -> “Storage” -> “Manage Storage” , select the most frequently used applications and check “ Documents and data ". Often, with a relatively small “weight” of one or another program, it takes up a lot of space. And if there are several such programs, then over time the smartphone begins to “slow down”. Therefore, the cache must be cleared regularly.

You can do this manually by simply reinstalling the application, then the “ Documents and data» is automatically cleared. But it’s better to use a utility like iCleaner for this, with which the process of cleaning the iPhone 7 from any unnecessary debris will be much more effective and less troublesome.

Hello! We have already sorted everything out possible problems(and their solution) related to connecting an iPhone or iPad to Wi-Fi -. But the fact is that that article discussed general problems, but today I want to talk about one specific case. And this case, it should be noted, is very interesting.

So, I recently received a letter with a question that went something like this: “Good day! This morning my iPhone lost Wi-Fi connectivity. The thing is that when I went into the settings, I tried to turn on Wi-Fi, but nothing worked - the slider did not move. For some reason it appears gray and cannot be activated. Please tell me what to do?”

But indeed, there is some strange “glitch” of iOS - there is a Wi-Fi button, but it cannot be pressed. Or is it not a “glitch”? Let's figure it out, let's go!

In fact, the problem can be either software or hardware. And of course, first you need to rule out failures in the iOS system. To do this, perform the following steps:

1. Hard reboot - performed differently for different models ().
2. Reset network settings. To do this, open “Settings – General – Reset – Reset network settings”.
3. If there is a jailbreak, then . Since some of its tweaks may affect the performance of the Wi-Fi connection.
4. Are you using a beta version of the firmware? Remember that from her - do it.
5. Create backup copy and restore iPhone firmware or iPad via iTunes (to be sure,). See if the Wi-Fi icon activates on a completely “clean” (without your data) device.

Have you done all these manipulations, but the problem still persists? Unfortunately, in this case, the gray color of the button most likely indicates a faulty Wi-Fi module.

By the way, indirectly this fact can confirm the impossibility turn on bluetooth– its icon will also be inactive.

How can I find out more accurately? Open “Settings – General – About this device” and look at the Wi-Fi address line.

And what to do now - how to do the right thing?

• . If yes, then feel free to take it in for warranty repairs and let them sort it out themselves.
• Has the service period expired? Unfortunately, replacing and soldering a module is not the easiest operation - it cannot be done at home, without special skills and equipment. Therefore, you need to visit a service center. But there is good news - the cost of such a procedure is not very high. Although everything is learned by comparison...

And finally, I would like to note this point.

On the Internet, as a way to deal with non-working Wi-Fi, you can come across the following advice - put it in the freezer or heat the device. They say, then the soldering will fall into place and everything will work.

I don’t know whether you want to check this method or not, but you need to remember the disadvantages of such a solution:

1. It rarely helps.
2. The effect, as a rule, does not last long - after some time the Wi-Fi connection icon will again become gray and inactive.
3. You can easily overheat (overcool) the device and break something else - the motherboard, display, all kinds of controllers, modules, etc.

Therefore, in my opinion, this manipulation is an extremely dubious decision.

Although, if you are still going to throw out the device (since you simply don’t need it with a non-working Wi-Fi button), then you can try. But only at your own peril and risk, because the consequences can be unpredictable. I repeat, visiting a service center will be a much more correct action.
