Why Wi-Fi won’t turn on on iPhone 4. Hard reboot method

Product fans Apple We look forward to the release of any new product with the now legendary apple logo. At one time, the iPhone 4c was no exception.

But those who were lucky enough to buy this gadget over time faced some disappointments - one of the most common problems It became impossible to connect the phone to Wi-Fi.

The appearance of the iPhone 4s

The legendary iPhone 4s was presented to users in the fall of 2011. The design was the same as the previous 4, which was liked by many users due to the panel made of glass, the mirrored logo and metal rims on the sides. The difference in appearance between the devices was the placement of antennas on the body. To improve communication, the Cupertino team in the new generation placed them on the sides, and not on top, as was the case in previous model. The photos taken by the iPhone 4s can still be considered high quality. An innovation in the model under review is Siri, a virtual voice assistant.

For the first time in the long years of the company's existence, a presentation of a new product was made by Tim Cook, the man who headed Apple after Jobs. Steve himself died literally the next day after the presentation of the gadget, and many experts are confident that it was Jobs’ death that influenced the commercial iPhone success 4s.

The first problems in the functioning of the phone

When developing the device, the creators made a number of miscalculations. After the start of sales, many users began en masse to contact the company’s service centers with complaints about iPhone 4s and Bluetooth. After the diagnostics, specialists discovered defects in the spare parts that are responsible for the performance of these functions. The company recalled the phones to replace components.

Despite this, some of the devices, as usual after the presentation, managed to end up on the black market. Most iPhone 4s were sold to countries where there were no official sales, so they could not be replaced. These phones have not gone away and are actively resold from hand to hand to this day. If WiFi does not work on the iPhone 4s, then most likely this device belonged to the first batch. You can check this on the company’s website by typing Phone IMEI, where the build date will be indicated. If the phone was assembled in 2012, then the problem can be fixed by replacing the Wi-Fi module.

Demand for iPhone 4s today

Although the iPhone 4s was discontinued back in 2014, it is still actively selling. There are many who want to become owners of the legendary device. This is facilitated by the relatively low cost of the device (from $80 to $150) and a large number of released devices. Additionally, the phone has stylish design with a glass body and characteristics that are not inferior to competitors in terms of efficiency today.

The main advantage of this model is the fairly good speed of operation, which is ensured by the proprietary Apple processor A5 based operating system IOS. The phone cannot handle most modern games, but for quick and comfortable surfing the Internet it is more than suitable. The device can connect to the network using GPRS, 3G or built-in WiFi module. The 4G connection or, in other words, the LTE network mode does not work on the iPhone 4s, since the release of the smartphone occurred during the inception of this type of communication, and at that time it was not yet supported by many telecom operators.

What you need to know when purchasing an iPhone 4s

Those wishing to purchase an iPhone 4s need to take into account its age and understand that some parts have physically worn out during this time and require replacement, and be prepared for the fact that a number of parts could already have been replaced.

When checking a phone before purchasing, it is recommended to Special attention check the performance of the connection, the network level, test the quality of Wi-Fi signal reception, enter standard SSD commands. It is necessary to clarify whether the phone has been repaired. If it has been repaired, then you should not buy such a device. As a rule, service centers replace original, branded spare parts with cheap Chinese analogues.

Don't be surprised if the network or WiFi doesn't work while you're checking your phone. On the iPhone 4s, connectivity is the weakest link compared to other features. The causes of malfunctions can be various factors. For example, old spare parts, in this situation the problem can be solved by replacing them.

There are situations when users cannot understand why WiFi does not work on the iPhone 4s if the phone itself is in a metal protective case. You need to understand that the Wi-Fi module antenna in this model is connected to sidebar device in the form of a small plastic strip. A protective covering, which is made of dense material, muffles the signal level on devices, thereby creating problems in their operation. To solve the problem, it will be enough to replace the metal case with silicone or plastic.

Another view existing problems connection problems on iPhone 4s software. The reason for their occurrence may be active and continuous use of the device.

A simple solution to problems with Wi-Fi on iPhone 4c

If, during intensive use of the device, the signal level indicator on the iPhone 4s WiFi turns gray and the Internet does not work, then most likely the problem arose due to overheating of the Wi-Fi module. You need to understand that it is located in the same area as the processor, which gets very hot when overloaded, and its heat spreads to other parts. There is no need to panic and run to the workshop. Try simply turning off the device and leaving it alone for a few minutes. At restart the phone will work in normal mode, without any glitches. In the future, actively using the phone, he will need to be given a little rest from time to time.

In situations where WiFi does not work on iPhone 4s after updating the operating system, you can simply roll it back to previous version. If a rollback does not solve the problem, you need to do a hard resend on the device while holding down home buttons and tab, hold for 4-6 seconds, after which the gadget will reboot and all settings will be reset to factory settings.

The best inventions of 2017, it, like other smartphone models, has many problems. One of them - incorrect work Wi-Fi.

Owners of iPhone X and iPhone 8 are complaining about errors when connecting to wireless networks. The smartphone does not accept their password or simply resets the connection.

It turned out that the cause was the Wi-Fi module installed in the new iPhones, since they were the ones that were affected first. However, in most cases, this problem can be resolved by using one of the following methods.

System update

Many users ignore software updates, which often causes device malfunctions. Some iPhone X and iPhone 8 owners managed to solve their Wi-Fi problem by updating the system.

To install the latest available version iOS, you need to open the gadget settings, go to the menu Basic and select a sub-item Software Update. The smartphone itself will download the firmware and offer installation.

Hard Reboot

Almost all iPhone problems can be resolved by manually rebooting the device.

For restart iPhone 8, iPhone 8 Plus and iPhone X need:

• Quickly press and release the Volume Up key.
• Quickly press and release the volume down key.
• Then press and hold the Side key (which activates Siri and Apple Pay), until it appears Apple logo.

Reconnecting to a wireless network

If your smartphone refuses to connect to Wi-Fi and displays an error when entering the password, you can try to forget the selected network and connect to it again.

To do this you need:

• Open iPhone settings.
• Go to menu WiFi.
• Click on the icon with exclamation point to the right of the desired Wi-Fi network.
• Select option Forget this network.
• Then try to connect again.

Resetting network settings

Many errors in Wi-Fi work or mobile internet can be solved by resetting the network settings.

To do this you need:

• Open iPhone settings.
• Go to menu Basic.
• Open submenu Reset.
• Select option Reset network settings.

This way you can delete all cache, DHCP settings and other data associated with the Internet connection.

VPN blocking

Many iPhone owners use private virtual networks. Using them, you can gain access to services that do not work in Russia, as well as hide your presence on certain sites. However, an incorrectly configured VPN can also cause Wi-Fi problems.

To disable VPN, you need to:

• Open iPhone settings.
• Go to menu VPN.
• Click on the green button to the right of the item Connection Status.

If you can't do this manually, you can try disabling or uninstalling the application that was used to set up the VPN.

Disabling Wi-Fi networks in geolocation settings

Some users managed to solve the problem with Wi-Fi disconnection the corresponding option in the geolocation parameters.

To do this you need:

• Open iPhone settings.
• Go to menu Confidentiality.
• Open submenu Location services.
• Scroll down the list of parameters and find the section System Services.
• Then you need to disable the item Wi-Fi networks.

Changing DNS Settings

Often, automatically configured DNS servers work slowly, and sometimes do not work at all. For those who have encountered problems connecting to Wi-Fi, you should.

Hello! We have already sorted everything out possible problems(and their solution) related to iPhone connection 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 he shows up gray and it 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 eliminate failures in iOS system. To do this, perform the following steps:

1. Hard reboot - for different models produced differently ().
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 performance Wi-Fi connections.
4. Are you using a beta version of the firmware? Remember that from her - do it.
5. Create a backup 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 Wi-Fi problems module.

By the way, indirectly this fact can confirm the impossibility turn on bluetooth- its icon will also not be active.

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 to warranty repair- let them figure 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 visit service center need to. But there is also 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 find 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 - system board, display, all kinds of controllers, modules, etc.

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

Although, if you are still going to throw out the device (since with a non-working Wi-Fi button you just don’t need it), then you can try it. 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.

P.S. After reading the article, did it become at least a little clearer? Like and click on the buttons social networks, get +50% to Wi-Fi signal strength!

P.S.S. Do you have any questions, would you like to share a problem or some alternative solution? Welcome to the comments!

If Wi-Fi on your iPhone does not work, do not rush to take the device to a 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 gray
• Wi-Fi freezes after a short period of time
• The mobile internet button and Wi-Fi connection do not turn on
• 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 steps:

• 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 mobile phone Apple 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.

To disassemble Apple smartphones, two screwdrivers are usually 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 the 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.

From time to time, situations arise when Wi-Fi on the iPhone does not work for users of Apple smartphones. Most often, a successful connection of the phone to the network is done using simple steps for troubleshooting, although in rare cases more complex methods are needed. Before taking your phone to a service center, it is better to try to figure out why Wi-Fi is not working and find ways to fix the problem yourself.

Rebooting iPhone and router

First of all, obvious sources of breakdown are excluded. Often, a simple reboot of the device helps to cope with the problem. The point is that Apple smartphone many launched in background system services, which waste a lot of resources. After rebooting the iPhone, the services restart and work correctly.

To restart the device, you need to simultaneously press the button "Home" and a button "Nutrition" and hold until the screen goes dark and the Apple logo signals that the smartphone has begun rebooting.

If all these actions did not lead to the expected result, you need to check whether the Internet connection is stable. If there is no way to find out this using another device, you need to turn off the router, wait 10 seconds, and then turn it on again. The router will restart and the iPhone will connect to Wi-Fi if that was the problem initially.

Resetting network settings

Your smartphone's network settings contain data that includes connection information and network preferences cellular communications and the Internet. If one of these settings is damaged, it will prevent the iPhone from connecting to Wi-Fi.

The solution to the problem is to reset the network settings. To do this you need to go to "Settings" , choose "Basic" , then "Reset" And "Reset network settings" . Confirm in the dialog box if required. These manipulations delete saved connection data, so it is better to be prepared to find it again the desired network and enter the password if it requires it.

iOS update

Apple smartphones and software are updated regularly. The practical benefit of this is to guarantee stable operation devices. With each new firmware version, the shortcomings of the previous one are eliminated. However, sometimes this leads to compatibility issues.

Apple regularly releases updates for iOS that are designed to fix similar problems. Therefore it is necessary to check whether a new version firmware for the company's device.

You can do this by going to “Settings” => “General” => “Software Update” . If the screen indicates that an update is available, click " Download and install" . It is important not to forget to first connect your smartphone to the charger.

Backup, factory reset and data recovery

If, after the steps described above, you still cannot connect to Wi-Fi, you will need to proceed to more radical actions: restoring the iPhone to factory settings. This will delete all information from your Apple smartphone and return it to its original state. Therefore, before resetting all settings, create a backup copy. There are 2 ways to do this.

Using iTunes

If you have access to a PC, you can create and save a backup copy of your data to HDD computer. To do this, you need to connect your iPhone via USB and open iTunes. Provided it is used latest version software, a small one will appear iPhone icon in the menu bar. After clicking on it, the option “ Backup and manual recovery."

The “Create a copy now” button allows you to start the process of copying data to your hard drive.

If the parameter " Automatic creation copies”, this process will begin immediately after connecting the iPhone to the computer. You can see the date and time the last one was created in the “Last copy” item.

If you click the checkbox next to the Encrypt backup copy of iPhone", the system will require you to set a password. After this, it will be impossible to restore the iPhone without it. This will protect personal data from unauthorized access. Encryption also allows you to save your Health and Activity data.

Using iCloud

In the event that there is no access to personal computer, there is another way to create backup copy data: using cloud storage iCloud. However, to use this method, you will need to be connected to Wi-Fi networks.

First you need to go to “Settings”, click on [Name] and select iCloud. Then scroll down the list until the " iCloud copy" Enable the switch if it is disabled by default. Click “Create a backup copy” and do not disconnect from the Internet until the process is completed.

Reset

After creating a backup copy of the data, you can proceed to deleting the information and returning the iPhone to factory settings.

To do this you should go to "Settings" and press “General” => “Reset” => “Erase contents and settings” . Confirm your actions.

Once completed, the iPhone will return to the state it was in at the time of purchase. You can then configure it manually or restore it from a backup. The second option is faster and easier, but at the same time there is a possibility of returning an error that caused problems connecting to Wi-Fi on this device.

Hardware failure

If you still can't connect to Wi-Fi after checking the Internet and following the steps above, there may be a hardware problem. Hardware failure will be diagnosed and repaired only by official Apple representatives. You need to contact a service center to check your iPhone. If this is not possible, and you need to find out the cause of the breakdown in the near future, you can write to the online service Apple support on the company's official website.
