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.

In today's pace of life, most of us cannot imagine existing without the Internet. Large and small companies are equipped with computer services, through worldwide network. A huge percentage of the advertising tool, again thanks to the Internet. Communication in social networks, information on free topics and more, we can use all this thanks to the connection to the network. Wi-Fi is one of the ways to connect computers, tablets, phones... to the Internet. And of course, deprivation of this opportunity leads to a failure in our system. Not arbitrary, an emergency shutdown of the Internet can bring a lot of troubles and losses. And not a small part of users are clients Apple, and as a result, iPhone owners. Let's consider iPhone specs 4s and possible problems connecting it to Wi-Fi.

Problems with Wi-Fi on the iPhone 4 are not new. Possible reasons these are different. Malfunctions Wi-Fi connections may manifest itself as a lack of signal, i.e. This is when the device does not see the network, or maybe vice versa, it recognizes Wi-Fi, but there is still no signal. Sometimes wifi icon just freezes. However, problems can be different and occur for different reasons.

If Wi-Fi does not turn on on your iPhone, it is most likely due to:

1 Hardware reasons (related to breakdowns due to mechanical damage, that is, cracks, chips, just impacts of the device, getting into water, damage to the power supply circuit). 2 Software reasons (factory defect, crash or firmware error).

Methods and methods for troubleshooting depend on the indicators of malfunction and their causes. They may not be identical and the degree of resolution of problems with Wi-Fi connection may be completely different. And as a result, the very manifestation of these problems may not proceed according to the pattern.

Remedies

If Wi-Fi does not work on the iPhone 4s, there are numerous reasons for the breakdown and ways to fix it. For example: due to software features There was a problem with Wi-Fi. What can you do when the Internet on the iPhone 4s does not work? For this reason, you can resort to flashing it. Save everything first necessary files, so that they are not lost during reinstallation. Then connect to your computer and use the system recommendations for restoring the firmware. Problems of this kind are mainly detected on the fourth and less often on the iPhone 5 and iPhone 5s.

If, nevertheless, the reason why the Internet does not work on the iPhone is due to hardware failures, then a more detailed and in-depth dive into the essence of the problem is necessary. And this is done through device repair. Repairs take place in the workshop. Experienced specialist complex work is carried out with a microcircuit, parts of an electronic device and takes certain time. Experts in this field often deal with this problem. But before you spend money and time on going to a service center, you can try to fix all Wi-Fi problems yourself. But it should be noted that there is a guarantee for service and return in case iPhone malfunctions, burns out. So, if you decide to fix the iPhone 4 yourself, you must be careful and strictly follow the recommendations on this topic.

The first method is when you take an ordinary hair dryer (in no case a construction hair dryer) and start exposing the iPhone to a hot stream of air, maximum mode. After which a warning about too much should appear on the device display. high temperature, this will be a signal for the end of the temperature attack. Next, you need to reboot your smartphone. The device must connect to Wi-Fi.

The second method seems simpler, but also less effective. You need to take your faulty iPhone and place in a regular refrigerator for 15 minutes. Then, just like in the first case, reboot the device. The device will begin to function correctly.

If the above methods did not help, then you may have to fix the breakdown with more complex manipulations. Of course, if you have previously resorted to repairing faulty electronic devices, there will be no problems. But in any case, we will try to present the entire iPhone repair scheme in the most accurate form.

Hard Reboot Method

An ordinary reboot of course at this stage corrections will not help. Here you need to turn off the iPhone by simultaneously pressing two buttons, “Home” and the power button. After which, upon startup, everything should return to normal.

Or by synchronizing your device with your computer via iTunes program. After connecting, the system should provide an option to restore and iPhone update. Click and wait for the update to happen. Then, when you turn on and detect the wireless network, the electronic mechanism should work as it should.

Repairing a gadget using the method of unscrewing the case

There are special tools for microcircuits and unscrewing the case in the form of screwdrivers. You can purchase them in a specialized store. We will need two types of screwdrivers of the proposed tools. This is a Phillips screwdriver and a special screwdriver for smartphones. So, using a Phillips screwdriver, carefully unscrew the nuts securing the device body. We try to put them separately and all together so that they don’t get lost. Then we open the front cover and find a small square under a thin film, black in color; all movements must be careful with this complex electronic system. This is the Wi-Fi module board, which we will have to heat strongly with a hairdryer. We remove the film from the board and start heating it using the same technology as in the first method. The task is to heat up this particular square and press it using a piece of cardboard or other material. We need that, under the influence of pressure, all the detached contacts are connected and, as they cool, are in strong contact. After the mechanism has cooled down, you can try a control check of the smartphone. Wi-Fi should work.

Other causes of problems why Wi-Fi does not work on iPhone 5/6 and more often version 4

Perhaps this is due to a more complex operating system, which is not entirely compatible with the old device, hence the failures and system errors. Also, possible interference in the operation of the gadget can be caused by various malware. Be careful when working with unverified sources of applications and downloaded programs. Don't forget that Apple took this seriously. possible problem, providing users with the opportunity to use only native programs and applications. Do not pump up your rather sensitive iPhone 4s with illegal programs. Subject to all recommendations, the device, that is, bluetooth, wireless internet must work accurately.

Note that the main cause of failure is related to the wireless network and Bluethooth of the series in question, namely the iPhone 4s in the contacts of the Wi-Fi module board, their disconnection. This is eliminated due to the method of temperature influence on the device parts. But still, if you are not sure of the reasons and that you can cope, we advise you to contact 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 communication 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 new version firmware for the company's device.

You can do this by going to “Settings” => “General” => “Update” software» . 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 hard drive 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 “Manual Backup and Restore” will appear on the right.

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 a backup copy of your 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 settings

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.

As a rule, happy owners of iPhones and iPads, unless their devices are damaged, are rarely regulars at repair centers. At the same time, users have no complaints about either the operation of cellular communications or the Wi-Fi module. But such cases still happen, and each time the malfunction can manifest itself differently. For some devices, the connection icon becomes gray or inactive, for others, the data transfer speed is reduced to a minimum, and for others, routing failures are observed. In some cases, the gadget simply does not see any of the wireless networks, although they exist and are simply not displayed.

Reasons for absence Wi-Fi access on the phone can be varied

There is no single cause of device failures - they all occur spontaneously. There are no particular difficulties with specific models iPhone or operating versions iOS systems. In most cases, all problems that arise can be solved by a simple reboot, as well as resetting the network settings. There is a possibility that the problem in the Apple device is due to hardware failures. In such cases, experts advise contacting one of the service centers for help. Apple Centers. For those who are used to always dealing with difficulties on their own, we offer several tips that will help iPhone and iPad devices connect to Wi-Fi.

The simplest and most logical method for solving numerous difficulties with connecting to Wi-Fi is to reboot the device (turn it off and then turn it on after a few seconds). This method will not tell you why the problem previously occurred, but it will often help solve it. To implement this method, you need to find the “Power” button, which you need to hold for a few seconds until the “Power Off” indicator appears. Then click on it to turn off the device. If the device does not respond to your commands, you will have to use forced shutdown gadget, for which you need to hold the “Home” and “Power” keys for about 10–15 seconds. As a rule, after next switch on device, it will perform its functions perfectly, all you need to do is click on the Wi-Fi connection icon.

Resetting network settings

Resetting the network settings on your iPad or iPhone will cause you to lose information about DNS servers, as well as access to home Wi-Fi, as the IP address information on the device will disappear. Along with this, logins, passwords and a lot of other information that was on the device will be lost. That's why the best option for the thrifty gadget owner there will be a reset network settings, which can be done by going to the menu: “Settings” - “General” - “Reset” - “Reset network settings”. Thanks to this operation, you can get rid of minor violations in the settings. By returning to standard settings you will be able to work in original mode. If the gadget still does not see the connection, you need to use other methods.

Backup, information recovery

Not every user of Apple devices understands the meaning backup. Those who know about it still rarely use it, as it takes away their energy and time. In fact, with the help of information backup technology, you can often avoid many problems, including non-working Wi-Fi. iPhone devices are often used to backup data. cloud service iCloud. But if Wi-Fi does not connect, you need to place a copy of the data in iTunes in advance.

Creating two backup copies will be a real lifesaver for you. Therefore, you can easily use iTunes and iCloud for this at the same time. And if now with your device, settings, system data or network connection anything happens, you can easily restore the data thanks to recovery from the saved array. The process of saving and restoring is quite simple; you will only need a little time, which will depend on the amount of information you sent to the cloud or returned back. Therefore, why not solve the connection issue with minimal intrusion into the gadget’s software.

You can do a full reset iPhone settings and iPad, which will allow you to return the gadget to its “just purchased” state. Of course, after this procedure it will be more difficult to restore all information. But if after full reset Wi-Fi connects and works fine, you will still have some spare backup, which you can use. However, one should not exclude the possibility that the problem itself becomes the culprit. backup version, - even if the system is updated, the situation will not change. In this case, a reset to factory settings will be relevant, which will allow you to set up Wi-Fi on your iPhone or iPad. In this case, you will have to restore the entire amount of information manually, collecting it literally bit by bit.

Why wasn't the problem solved?

Why in some cases all operations do not bring the desired result, and the iPhone does not see wireless connection to the Internet? The fact is that the iPhone and iPad are not always the culprit of the problem. Often the router fails, which is separate device with its software, which often presents unpleasant surprises. In this case, you can also solve the problem by rebooting the router - to do this, just turn off and turn on the power of the device. If the device connects, but the Internet speed is extremely low, you need to change the DNS server settings. However, if your knowledge in this area is minimal or all attempts to restore the router have ended in failure, it is better to entrust all work to

How nice it is to sit in a cozy cafe, library or airport and connect to the wireless Internet! Imagine that Wi-Fi suddenly stopped working on your iPhone. But this problem occurs to smartphone owners quite often. Such an incident interferes with work, communication with friends, and searching for valuable information. You may not have time to buy a plane ticket, write important letter colleague, etc.

You understand, such technical problems are expensive. However, you will soon see that if Wi-Fi suddenly does not work on your iPhone, then this problem can be solved.

Let's figure it out

All causes of the problem are divided into only two types:

1. hardware;
2. software.

The latter are often easy to fix on your own, without the help of specialists. With hardware, the situation is more difficult, since they are associated with design features smartphone and possible factory defects. Certainly, Apple gadgets undergo the most rigorous testing, but users have repeatedly noted cases when Wi-Fi stopped working on the iPhone 4. Similar situations happened with other models.

Very often, the board comes off due to the phone falling from a height onto a hard surface, such as the floor or asphalt. Even if the iPhone didn't fall apart, there could have been a shock inside the case that caused the contacts to break or loosen, so wireless network stopped working.

Hardware reasons

These iPhone problems are not associated with operating system firmware, viruses or the installation of unusual software. The cause is usually a broken contact with the board. It happens that Wi-Fi did not work on the iPhone 4s due to insufficient contact of the board. The network may not be detected at all (the slider in the settings does not work), it can only be detected two steps from the router. This situation also happens with other models. Of course, it is wiser to contact a service center, but it is possible to carry out repairs yourself, naturally, saying goodbye to the warranty card and other obligations of the manufacturer.

Watch the video, it shows how to fix an iPhone using a hairdryer:

Let's disassemble the gadget

If the above manipulations do not help, you will have to take a screwdriver. We need two of them:

We act in stages:

Watch the video, it shows in detail the process of disassembling and repairing Wi-Fi on an iPhone:

Software flaws

It happens that the wireless network does not work due to system errors. Often the reason is the transition to iOS 7. This operating system has undergone serious changes under the strict leadership of Apple Vice President Jonathan Ive. The design, interface and general structure of the operating system have changed. The eighth version is also not stable even compared to Android. If Wi-Fi isn't working on your iPhone 5s, it might be a firmware issue. Don't change operating system without much need. Remember that the new version may not be fully compatible with the old gadget.
