Iphone 7 wifi doesn't work. WiFi does not work on iPhone - fixing the problem

It's no secret that Apple smartphones known for their reliability and stability. However, there are times when problems may arise when using the phone. Let’s look at the causes of the common problem “wi-fi doesn’t work on iPhone.”

Physical damage

The main reason why wi-fi does not work on an iPhone is that the phone has been dropped or physically damaged. As a result, the following components may fail:

• impact of antenna elements - as a result of a fall, hidden antenna elements may be damaged, and the bolt heads may also be injured. Because of this, the reception of the Internet signal deteriorates significantly and wi-fi may not work at all;
• breakage of the antenna at the junction point - failure is possible only if there is a strong impact at the point of attachment to the clamp or at the junction point of the connector. IN in this case wi-fi stops working altogether;
• Damage to microcircuits is a common cause of the problem. Chip dysfunction occurs as a result of the phone hitting a hard surface or object. Therefore, the Internet signal reception point becomes inactive.

As a rule, these faults can be easily fixed in a workshop by replacing the signal reception antenna or microcircuit.

Special case

There are situations when Wi-Fi on the iPhone stops working, but at times it is still active. This happens when the legs of the chip were “injured” during damage. When the temperature changes, they begin to “play”, either giving access to wi-fi or blocking it.

Most often, such problems arise in the winter season, when temperature fluctuations outside the window are maximum. However, this situation can also be observed in the summer. For example, during severe overheating, the phone will start to work properly, but access to the network will be stopped after it cools down.

Other reasons

A short circuit in the power supply can cause problems with your phone. Most of the time this happens when the user instead of the original charger uses a copy. The fact is that the original products have fuses that protect the smartphone from voltage surges.

Of course, the creators of the counterfeits did not worry about a similar level of security for the iPhone. Therefore, your phone can work properly until it is charged, and stop picking up wi-fi after it is disconnected from the power supply.

Another common cause is moisture getting into the phone. In this case, the contacts of the antenna or microcircuit are damaged and begin to oxidize. This leads to their complete failure or partial failure (when the phone sees the wi-fi network periodically). This reason is also the answer to the question: why doesn’t iTunes see the iPhone?

The listed causes of the problem can be eliminated by opening the phone, diagnosing the specific part that was damaged and replacing the necessary parts.

The network works, but poorly - why?

There are often situations when wi-fi works, but poorly. The Internet starts working when you approach the router itself. This happens because between motherboard and the antenna has a poor connection. If your phone has already been repaired for some reason, the problem may occur in the following cases:

• the fastening screws were mixed up;
• the chip plate was lost;
• the coaxial cable was pinched;
• the connector was not connected.

Software reasons

The cause of the problem may be software flaws. A common situation is installing a new software, which has significant changes in the design, interface and structure of the system. If you are using latest version smartphone, then problems of this kind will not bother you.

However, when using earlier models, a similar situation may well occur. The new version and your gadget may not be fully compatible. Cause bad wi-fi works Your phone may become infected with viruses.

Sometimes some iPhone users experience a variety of problems 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 ways to troubleshoot iPhone wireless problems.

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 a huge 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.

Create backup copy iPhone 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. IN otherwise The best way is to contact Apple support, describing the problem in detail.

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 IOS version. 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 the 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 lately The phone finds Wi-Fi networks and connects to them, 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. From the list of available options that appears, 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 solve most software problems with your 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 that works with Wi-Fi and Bluetooth signals. 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.

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 - 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. Back up and restore your iPhone or iPad firmware 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 the module is not the best simple operation– it cannot be carried out 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 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 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, visit service center would 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!

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-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 the network bandwidth 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 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.
