Wi-Fi does not work on iPhone. The Wi-Fi button is gray and inactive - what happened to the iPhone

Twitter

Sometimes some iPhone users There are a variety of problems with connecting to wireless networks. There are situations when the Wi-Fi connection is lost, the Wi-Fi on/off toggle switch may be blocked, available wireless networks are not displayed, or the phone simply does not connect to Wi-Fi.

There is no single reason for such problems. But in most cases this is all easily fixable. Here are some troubleshooting methods iPhone work with wireless networks.

Press and hold the power button and home button at the same time until your iPhone restarts.

Once the iPhone restarts, it will try to connect to Wi-Fi again. In some cases, this immediately solves the problem.

Resetting network settings

Your phone stores great amount network addresses, passwords and other parameters and, perhaps, because of all this rubbish, something was broken.

Open Settings and go to General, then select Reset Network Settings from the Reset menu.

When the network settings are reset, try connecting to the Wi-Fi network again. Everything should work, but if that doesn't work, we have a few more tips.

Backup and Restore

Backup and iPhone recovery brings some inconvenience, but it often solves the most serious problems associated with the incorrect operation of your phone.

Back up your iPhone with using iTunes or iCloud and recover from it. Then try connecting to your Wi-Fi network again. This is not at all difficult, but it can take quite a lot of time.

If, nevertheless, this advice did not help you, then perhaps the problem is not in your iPhone at all. Check your router settings and reboot it. Otherwise, the surest way would be to contact the service Apple support, in more detail describing the problem.

If Wi-Fi on your iPhone doesn't work, don't rush to take your device to service center. First, try to fix the problem yourself. As soon as there is a problem connecting to wireless network, reboot the device and reset the settings. There are also other ways to troubleshoot Wi-Fi problems, depending on the cause of the problem.

Main causes of malfunction

If you surf the Internet frequently, the quality of your wireless network reception is very important. Therefore, when Wi-Fi stopped working on the iPhone (does not catch the network, freezes or works with bad speed), this can become a very annoying problem. You can try to restore the device yourself or use the help of experienced specialists.

There are reasons why Wi-Fi on an iPhone may stop working:

hardware failure
software glitch
accidental reset
mechanical damage to the device
moisture getting inside the smartphone

Software failures and lost network settings can be easily fixed by yourself.

Signs of Wi-Fi failure

Understanding that there are problems with Wi-Fi is quite simple. If Wi-Fi is not very fast, perhaps the problem is not in the smartphone, but in the router. Therefore, first check that your router settings are correct.

The following signs indicate a Wi-Fi malfunction:

the device does not connect to the network
The smartphone does not connect to the access point
Wi-Fi icon is on gray
Wi-Fi freezes after a short period of time
the button does not turn on mobile internet, Wi-Fi connections
Internet does not work well (low speed)
network settings are lost

Certainly, Apple technology undergoes rigorous testing during production, but some users notice that even new iPhone Doesn't pick up Wi-Fi. Fixing a software glitch is much easier than fixing a hardware problem that causes Wi-Fi to not work on an iPhone. In any case, the method of troubleshooting depends on the type and complexity of the breakdown.

What to do if Wi-Fi does not turn on due to a software failure

It happens that Wi-Fi freezes and functions poorly due to system errors. Often the cause is a software glitch after updating the operating system. However, there are others software reasons, because of which Wi-Fi does not work very quickly or does not turn on at all.

If your iPhone stops functioning normally, Wi-Fi works poorly or does not turn on at all, the button does not turn on, the icon is gray, or you find other signs of a malfunction, try the following actions:

reboot the router
If rebooting the router does not help, force a “reboot” of the mobile device
if Wi-Fi does not work or freezes, update the operating system
install an antivirus, your iPhone may be infected
try connecting to mobile internet

If the steps performed did not help, and Wi-Fi is in your mobile Apple phone did not work, the problem is most likely in the hardware. The reasons for such breakdowns are quite varied, ranging from breaking contacts with motherboard and failure of the power button cable, ending with module failure.

What to do if Wi-Fi does not turn on due to a hardware failure

The hardware failure is not related to the OS firmware or malware. This problem is quite annoying. Incorrectly performed repairs can affect not only the operation of Wi-Fi, but also other functions of the iPhone smartphone.

You can find the following methods on the Internet: self-recovery Wi-Fi hardware:

warm up the switched-on iPhone with a hairdryer at the maximum power level - if a warning appears on the smartphone screen about the maximum high level temperature, stop heating immediately and reboot the device
If Wi-Fi still doesn't work, try putting your iPhone in the refrigerator for no more than 15 minutes, then reboot your smartphone

These methods are quite simple, but they are not always suitable, so if you are not sure of the correct actions, it is better not to do anything until you disassemble the device.

How to repair a gadget by first disassembling it

If your smartphone's functions are not working well or have not been restored at all, disassemble the device using special tools and try to determine what the problem is.

For disassembly Apple smartphones Usually two screwdrivers are enough (a regular Phillips screwdriver and a specialized one for smartphones). Once you have your tools ready, follow these steps step by step:

unscrew the fasteners and remove the front cover of the iPhone
find a Wi-Fi module (1 by 1 cm square, covered with a thin film)
carefully remove protective covering using tweezers
slowly, at an angle of 90 degrees, start warming up the module with a hairdryer, carefully directing hot air onto the board
move the hairdryer evenly around the perimeter of the Wi-Fi module
After heating the board, press it to the contacts, secure the square with a small piece of cardboard
wait until the components have cooled down completely and turn on the iPhone

After such actions, Wi-Fi usually begins to function stably, however, situations arose in which smartphone owners discovered additional malfunctions.

This kind of trouble can happen to anyone. iPhone model, therefore, if Wi-Fi does not work and you do not know what exactly the problem is (in software glitch, in the module, power and volume buttons or other hardware elements), you doubt the successful completion self-repair, use the services of qualified specialists.

Connect to Wi-Fi - the same required function For modern phone, how to make calls or send 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:

Hardware - everything related to mechanical damage iPhone, module burnout or manufacturing defects.
Software - incorrect operation of the operating room iOS systems 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 - reconnection. 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 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 everything custom settings and the programs will be removed.

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. Most the best option- 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. More information about the location and complete process For replacements, 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 reboot and other 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.

I can confidently say that almost every second iPhone owner 4S faces such a problem when it does not work or catches Wi-Fi in the iPhone very poorly. Let's look at why this is and how we can fix it.

People often come to us with the problem that Wi-Fi does not work in the iPhone 4s. Although not only this model has such problems, but in other iPhones this occurs much less often. And so, first of all, let’s figure it out: is your Wi-Fi not working at all or is it poorly received?) Because they say “Wi-Fi doesn’t work”, but in fact it finds Wi-Fi networks poorly or very poorly.

Option #1 - Wi-Fi does not work (At all)

In this case, you will see the following in your iPhone settings:

As you can see, the “slider” is not active and cannot be turned on. In this case, in the iPhone 4s (although not only in the iPhone 4s, in other models it will be exactly the same with the Wi-Fi switch) Wi-Fi module.

Surely everyone will try to save money and fix this problem on their own; you will start looking for ways on the Internet and come across a couple of methods.) The first is to throw the iPhone in the freezer, the second is to heat the iPhone with a hairdryer. In both cases, Wi-Fi can, I emphasize MAYBE (that is, not a fact), work, but not for long. But you can also “finish off” your iPhone 4S completely; in the best case, it will be restored by a service center like us. In the worst case, you just throw it in the trash)

I’ll explain from a technical point of view why these methods are (possibly) temporary! they will help you.

But before we start, I want to say that this problem can only be solved with the help of . By replacing the Wi-Fi module itself. And nothing else!!!

Let's continue.

Here iPhone photography 4S, on which I allocated the Wi-Fi module itself, this is a small chip on the motherboard.

Accordingly, during heat treatment (whether you put it in the freezer or heat it with a Hairdryer), this chip and its contacts will expand and contract (Physics :)) and the contact with the motherboard will POSSIBLY improve and Wi-Fi will appear for a while.

Now why you shouldn’t do this:

1) If you put it in the freezer, condensation will form inside the iPhone 4S and then it can short/short very well and then you will 100% contact the iFixApple Service Center))) But even here, after such methods, it is not always possible to restore the iPhone.

2) If you start heating the iPhone 4S with a hair dryer, then everything is very simple, you can easily melt absolutely everything that is inside the iPhone itself. Accordingly, here you will have to go to the SC, and also, depending on your luck there) Either they will restore it or it will be trashed)

Option No. 2 - Wi-Fi does not work (poor reception)

Surely you've seen this when you can't find it in the settings at all Wi-Fi networks, only if you go straight to the Wi-Fi router, you almost have to put it on the router itself in order for it to find the network.

Most often, in this case the problem is Wi-Fi antenna. Or bad contact Antennas with the motherboard or you just need to replace this antenna. This is what she looks like:

That's all, I hope I told and explained all your questions. In any case, our team Apple lovers recommends not to sacrifice the device and entrust the solution to this problem to professionals.

Most often, WiFi does not work on iPhone 4s for several main reasons, the main one of which is weakness WiFi module towards external factors. Water ingress, overheating, pollution - any intervention can be fatal, but all this is fixable.
In addition, there are less predictable reasons, the ways of identifying and eliminating which every owner of Apple equipment should know.

Why WiFi doesn't work on iPhone 4s: main reasons

There are several possible events that led to this failure:

Crooked firmware or incorrect installed configuration. The device itself is intact and functions correctly, but due to glitches in the system or incorrect signals, it is interpreted incorrectly, which creates the illusion of failure.
Third party software, affecting the Internet channel. Some applications, intentionally or accidentally, can completely clog the communication channel with background streams, which makes you wonder: why doesn’t WiFi work on iPhone 4? Closing them is not enough; decisive action is required to clear the phone’s memory.
Module failure. The saddest situation is that entails either long hours of painstaking self-repair, or large expenses for paying for the services of a service center. Here, independent intervention can worsen the situation.

Don’t be afraid in advance: even if Wi-Fi doesn’t work on your iPhone 4s, you can still fix it, often on your own.

Flashing and resetting

As mentioned earlier, an unsuccessful update or a faulty flashing of the phone can lead to incorrect operation of the modules. In the absence of other reasons, all this can be corrected in two ways:

Safe method. If WiFi does not work on your iPhone 4s, then make a backup in iCloud or via iTunes, and then reset the settings to factory defaults. To do this, go to Settings -> Reset -> Reset all settings. If the iOS image was intact, after some time iPhone time will start up again and work without interruption.
Dangerous method. If Wi-Fi does not work on the iPhone due to a broken firmware or the iOS image is broken, then the only way out is to reflash it via DFU mode. If you don’t know how to do this, it’s better to contact a service center so as not to turn your Apple device into a brick.

Third Party Applications

When wondering why Wi-Fi doesn’t work on iPhone, first of all check all incoming and outgoing traffic. It is possible that some of the recent installed applications Something is constantly downloading in the background. The solution to this problem is trivial: delete the application and restart your iPhone.

If there are no signs of the Internet being busy, but WiFi still hasn’t started working, then do a hard reboot by holding down the Power+Home keys for 5-7 seconds. This will help clear not only the Internet channel, but also RAM along with processor registers.

Physical breakdown and repair

Wi-Fi does not work on iPhone 4 after the procedures described above? Well, our condolences: you have encountered mechanical damage to the communication module. It is strongly recommended that you immediately take the device to service, but if you want to try to fix everything yourself, read below.

WARNING: You carry out all actions at your own peril and risk; the described algorithms are not recommendations.

You will need: a hair dryer (construction or regular), a set of screwdrivers for disassembly and free time.

"Lazy" blowing. The phone warms up without disassembling, which allows you to remove moisture from other components. Unfortunately, after such a purge, the service life of the phone is a maximum of several months (although there are lucky people who still use iPhone 4).
Gentle blowing. WiFi doesn’t work on the iPhone, so let’s remove the module itself and heat it with a hairdryer. With this method, even careless actions are less sad: only the module will need to be replaced, while the rest of the phone can work for years.

In both cases, the main thing is not to overdo it and let the device cool down before starting, otherwise you risk spending money on repairs. more money than buying a new iPhone (especially if backup copies no data available).
