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’s unpleasant that Wi-Fi on the new iPhone 7 (or vice versa, iPhone 7 in Wi-Fi) starts to become “stupid” and “slow down” 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 that provides higher data transfer speeds;
- buy a new, more modern router (here link to the website catalog of Wi-Fi routers);
- hard reset iPhone 7 (full system reset), if other methods did not have 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.
From time to time, situations arise when Wi-Fi on the iPhone does not work for users of Apple smartphones. More often than not, connecting your phone successfully to the network can be achieved using simple troubleshooting steps, 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 fact is that the Apple smartphone has many system services running in the background that 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 preferences for cellular and Internet networks. 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 the desired network again 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 of the device. With each new firmware version, the shortcomings of the previous one are eliminated. However, sometimes this leads to compatibility issues.
Apple regularly releases iOS updates that are designed to fix issues like this. Therefore, it is necessary to check if a new firmware version is available 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 your computer's hard drive. To do this, you need to connect your iPhone via USB and open iTunes. Assuming you are using the latest version of the software, a small iPhone icon will appear 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 “Automatic creation of copies” option is set, 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 Encrypt iPhone Backup, the system will ask 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
If you do not have access to a personal computer, there is another way to create a backup copy of your data: using iCloud cloud storage. However, to use this method, you will need to be connected to a Wi-Fi network.
First you need to go to “Settings”, click on [Name] and select iCloud. Then scroll down the list until the "iCloud Copy" button appears. 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 Apple online support on the company’s official website.
Poor Wi-Fi on iPhone? iPhone constantly disconnects from the Wi-Fi network and resumes operation only after a while? Wi-Fi speed on iPhone has dropped noticeably and still won't return to normal? If you are facing any of these issues, this guide will definitely help.
Perform a force reboot
You should start looking for a solution to the problem of poor Wi-Fi reception on the iPhone with the simplest method - performing a forced reboot. It helps to reset iOS software errors that have arisen, including even those that at first glance are related to the hardware. In order to force restart your iPhone you need to hold down the buttons Nutrition And Home(Volume Down button on iPhone 7/7 Plus) and hold them until the Apple logo appears on the screen. After turning on the device, you should check that Wi-Fi is working correctly.
Reconnect to the Wi-Fi network
Also, quite often, a simple reconnection to the network helps solve the problem with a poor iPhone connection via Wi-Fi. For this:
Step 1. Go to menu " Settings» → WiFi.
Step 2: Select a wireless network that is slow.
Step 3: Click " Forget this network».
Step 4: Search for wireless networks and connect to the network you just deleted.
Please note that after resetting, the Wi-Fi network password will need to be entered again.
Reset network settings
One of the most effective ways to solve the problem of poor Wi-Fi connection on iPhone is to reset the device's network settings. It is performed as follows:
Step 1. Go to menu " Settings» → « Basic» → « Reset».
Step 2: Click " Reset network settings».
Step 3: Confirm the operation.
After resetting the network settings is successfully completed, you can check whether the iPhone works faster on your Wi-Fi network.
Use an alternative DNS server
The next method is non-standard. In the connection settings, you must specify an alternative fast DNS server, for example, Google. This will allow the connection to work faster on your specific device.
Step 1. Go to menu " Settings» → WiFi.
Step 2: Click " i» next to your connection.
Step 3. In the DNS column, enter one of the following DNS servers:
- Google - 8.8.8.8.
- Google - 8.8.4.4.
- OpenDNS - 208.67.222.222.
- OpenDNS - 208.67.220.220.
After that, exit the connection settings and check if its speed has increased. 
Set up a different Wi-Fi network broadcast channel
This method is especially helpful for people who live in apartment buildings literally teeming with Wi-Fi networks. The vast majority of networks operate on standard settings, broadcasting on the same channel. Installing another Wi-Fi network broadcasting channel makes it possible to significantly speed up the connection.
However, you will have to find the option to select a broadcast channel in the settings of your router yourself. The fact is that router management interfaces have different appearances, which is why, unfortunately, we cannot give the exact location of the required settings. Note that most often the option to change the Wi-Fi channel is available in the advanced connection settings.
Set a Wi-Fi password
And one more tip related to Wi-Fi network settings is extremely simple. Make sure that other people are not using your Wi-Fi, thereby slowing down your connection speed. The easiest way to do this is by setting a Wi-Fi password, thus prohibiting other users from connecting to the network.
Restore iPhone
If a Wi-Fi problem appears after installing an update on your iPhone, it may be due to a serious software error. You can get rid of it by restoring your iPhone via iTunes to the current version of iOS. You can find a detailed guide on how to restore an iPhone using iTunes.
If none of the above methods help, then you cannot do without the help of service center specialists.
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 number of 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
Backing up and restoring your iPhone can be a bit of a hassle, but it can often solve some of the biggest problems with your phone not working properly.
Back up your iPhone using iTunes or iCloud and restore 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 Apple support, describing the problem in detail.
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 the wireless network, restart 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 stops working on the iPhone (does not connect to the network, freezes or works at poor speed), this can become a very unpleasant 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
Of course, Apple equipment undergoes rigorous testing during production, but some users notice that even the new iPhone does not catch 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 other software reasons due to 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 you performed did not help, and Wi-Fi in your Apple mobile phone does not work, the problem is most likely in the hardware. The reasons for such breakdowns are quite varied, ranging from broken contacts with the motherboard and failure of the power button cable, to 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.
On the Internet you can find the following ways to independently restore Wi-Fi hardware:
- warm up the turned-on iPhone with a hairdryer at maximum power level - if a warning about an extremely high temperature level appears on the smartphone screen, immediately stop heating 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.
Such a nuisance can happen to any iPhone model, so if Wi-Fi doesn’t work and you don’t know what exactly the problem is (a software glitch, a module, power and volume buttons, or other hardware elements), you doubt the success of doing it yourself repairs, use the services of qualified specialists.
