Check if the password you entered is correct

Let’s start with the simplest, but still one of the most common reasons iPhone or iPad won’t connect to Wi-Fi. Yes, it is often the incorrectly entered password that prevents your device from connecting to the wireless network.

There is no wisdom in checking the correctness of the entered password. you just have to enter the code word with maximum accuracy and case-sensitive. It will not be superfluous to check if the password is correct on another device. If another smartphone or tablet easily connects to the desired Wi-Fi network using the password you specify, then you did not make a mistake when entering and the problem lurks somewhere else.

iPhone Won’t Connect to Wi-Fi. What to Do?

Problems related to the inability of an iPhone or iPad to connect to Wi-Fi often occur to owners of Apple mobile devices and, what is saddest, just as often these problems remain unresolved for users. In this guide, we have described the most effective ways to restore Wi-Fi on iPhone and iPad.

Reset network settings

If the previous method did not help, then it’s time to move on to heavy artillery. The last way to restore Wi-Fi operation is to reset the network settings, which is done like this:

Go to the Settings menu. Basic. Reset

iphone, does, wi-fi

Select “Reset network settings” Confirm the action by clicking “Reset” After the network settings are reset, you can check the Wi-Fi operation.

Perform a forced reboot

Another easy way to get Wi-Fi working is to perform a forced reboot. Just hold down the Home and Power buttons together and hold until the Apple logo appears on the screen. If after rebooting Wi-Fi still does not work, move on to more radical solutions.

Router problem

If none of the above methods helped, the problem lies either in the incorrect settings of the router, or in the inoperability of the Wi-Fi module of your device. In the first case, the following should be done:

Note: only advanced users are recommended to change the router settings.

  • Reboot your router
  • Reset router settings
  • Change the encryption settings from WPA2 / WPA to WEP. It’s worth a try and completely temporarily leave the access point without a password.
  • In the parameters of the router, change the region of use to USA

Try to reconnect to the network

This method helps in most cases when the iPhone or iPad does not connect to an already known Wi-Fi network. Its meaning is that you must first forget the wireless network, and then reconnect to it. This is done as follows:

Go to the Settings menu. Wi-Fi

Select the problematic wireless network

Click the Forget This Network button

Search for wireless networks and connect to the desired one by re-entering the password

Please note that the password will need to be re-entered after the reset, so make sure you know the code word.

  • Feedback from interested professionals only
  • Don’t waste time communicating with intermediaries

The fact that the iPhone does not catch Wi-Fi well is faced by many users. Often, the ways to solve the problem are quite simple, you can eliminate the cause of the weak signal yourself. The main thing is to pay attention to the situation in a timely manner and determine the type of malfunction, as well as a way to eliminate it.

Signs of defective Wi-Fi on iPhone

If your device has a poor view of the wireless network or the Wi-Fi connection does not work completely, you will face a number of inconveniences.

The main signs that the iPhone is poorly picking up Wi-Fi are as follows:

  • a smartphone at a long distance began to catch the network poorly
  • the gadget only catches the network at a short distance
  • the device does not catch the network (the antenna does not see the network)
  • internet works intermittently

If you find one of the listed symptoms while the device is working, you can try to fix the problem yourself.

The most common causes of a weak Wi-Fi signal

Apple equipment is rightfully considered to be of very high quality, however, even new iPhones can fail. It is far from a rare type of malfunction that the Internet is working slowly or the smartphone has become poorly caught.

The reasons why the iPhone has become worse in catching the network or does not see it at all can be quite varied:

  • incorrect router configuration
  • faulty Wi-Fi module
  • software malfunction

To determine the problem, check your wireless network settings and try to reboot your device.

Troubleshooting methods

Before trying to troubleshoot, check your network settings and back up your data by connecting to mobile internet.

iPhone Not Connecting To WiFi? Here’s Why & The Fix!

If you’ve decided to fix problems with a weak Wi-Fi signal on your iPhone or a complete lack of access to a wireless network on your own, try the following steps in sequence:

You can reset network settings by following these steps:

  • In the “Settings” menu, go to the “General” tabs, then “Reset”.
  • Click on “Reset network settings”.
  • Confirm the reset by clicking on the “Reset” button.

After that, you need to check the connection, and if again you cannot catch the network, it is likely that an annoying nuisance due to which you cannot connect to the Internet lies in a router malfunction.

Reconnecting as a way to catch the network

If your iPhone 5S stubbornly does not want to see the network, and you cannot understand the reason why this is happening, try reconnecting the device to the Internet once or several times.

This method usually fixes the problem where iPhone 4 won’t connect to a known network. Although, if you have a different version of this gadget and have the same problem. for example, the iPhone 5 does not connect to the Internet. you can also try using the tips that will be given below.

So, if the iPhone can find a network, but it does not connect to it, follow these steps in sequence:

  • Go to the Wi-Fi settings through the gadget menu.
  • After selecting the network to which the device sees but does not connect, click on the “Forget this network” button.
  • Search for other Internet channels and try to reconnect to the WI-FI network. If, after that, your gadget does not want to look for other networks, then the problem has not been solved again and the reasons lie elsewhere.

Reboot, factory reset and repair

There are times when nothing helps, and why the iPhone does not connect to Wi-Fi only at home (or only at work) is difficult to say. The Apple Consulting Center says that in this case, you need to try resetting the settings or restarting the phone.

There are more serious reasons why you cannot log into the WI-FI network. For example, if the phone does not see any networks, this means that the module itself responsible for the Wi-Fi connection may be faulty. This is a serious breakdown and, of course, to fix it, you will need to contact the nearest service center that repairs the iPhone.

Of course, you can do without access to the Internet on your mobile phone. But, as practice shows, working via WI-FI from your iPhone is faster and more comfortable. In addition, there is no need to pay for wireless 4G Internet, thus, the savings are obvious. Therefore, if you encounter a problem, solve it and forget!

General order

To begin with, we will describe how the wireless connection of the phone to the Internet should take place. Perhaps by studying it, you can understand why the iPhone does not connect to Wi-Fi in your situation.

Using a WI-FI router, a wireless signal is distributed. By detecting it, mobile devices can access the network without the need for cords and wires. However, to do this, you must obtain permission to authorize on the network (if the latter is protected). Simply put, if Wi-Fi is closed, to enter it from your tablet, phone or any other gadget that you want to connect to the Internet, you must enter a password (network key). After that, the system will recognize you and give you the opportunity to log in.

Accordingly, three connecting elements are obvious in the whole scheme: the source of the Internet signal (a cord from a special socket for connecting to online); a router that distributes a signal; and, in fact, the phone itself. In some cases, another laptop appears instead of the signal distributor (if such a function is available on it). When it happens that you can’t figure out why the iPhone isn’t connecting to the laptop’s Wi-Fi, it could be one of these links. Our task to solve the problem is to identify the cause of the problem and fix it.

Why won’t my iPhone connect to Wi-Fi? Diagnostics and problem solving

Many people use a wireless (WI-FI) internet connection, and there are many reasons for this. First, Wi-Fi provides more mobility than wired connectivity, obviously. Secondly, in the case of a wireless access point, the user has the opportunity to use several devices at the same time, while you cannot connect, say, a tablet and a smartphone to a cord.

Connecting via WI-FI is convenient, but there are problems with it. For example, it so happens that the user cannot understand why the iPhone is not connecting to Wi-Fi. It would seem that he entered all the data correctly (meaning the password), chose the network, but it is impossible to access the Internet via a smartphone.

Read about how to act in such a situation and where to look for a solution to the problem in this article.

The first reason is the simplest

Sometimes the iPhone won’t connect to Wi-Fi because the owner of the iPhone 4, iPhone 5S, and other smartphone models entered the wrong password. What to do in such cases? The solution to the problem in such a situation is the simplest: enter the password again, more carefully filling in the appropriate field, rechecking whether the keyboard layout is correct.

You can also try to enter the password on another device, and if it turns out that it is correct, but the Apple gadget failed to connect to the network, then your iPhone does not see WI-FI for another reason.

Reestablishing a connection after a network break

To restore Wi-Fi on iPhone, we suggest trying the following recipes:

  • We go to the “Settings” menu. “WI-FI” and click on the “Forget this network” option. Then we try to find our network again.
  • If for some reason it does not work out, turn on the “Airplane mode”.
  • Try to cheat. in the network settings, select “Other” and try to connect by specifying the same network.
  • If for some reason all of the above does not help, and the network is still not there, then go to the network settings: “Settings”. “Basic”. “Reset”. “Reset network settings”. then configure everything again.

One of the listed methods should definitely help and the network will be with you again.

Configuring the router

If the iPhone does not connect to WI-FI, we need to open the router’s web interface and change the regional settings in it. Suppose you have a “D-Link” brand router (for models from other manufacturers, the setup process differs little), then we need the following manipulations:

  • Launch a browser on your computer.
  • We drive the IP address of the router into its address bar, usually it is
  • We go to the admin panel of the device and select the group of settings “WI-FI”. “Basic settings”.
  • In the drop-down list “Country” put the value “United States of America (USA)”.
  • We save the settings and try to find out if the iPhone connects to Wi-Fi. In theory, everything should work.

It so happens that yesterday your iPhone was perfectly catching Wi-Fi, but today it does not connect, even if you crack. Why is this happening? It happens that the settings fly off as a result of a network break. What to do in this case? There are several tricks with which you can restore WI-FI in this case.

iPhone Can’t See Wi-Fi. Troubleshooting

When iPhone is not connected to a wireless network, you need to understand the reasons why iPhone is not seeing Wi-Fi. How to fix the problem yourself, and in what cases you will have to contact the service center,

Checking the operation of the router

Rebooting your router solves most Wi-Fi problems. When restarting the device, it is recommended to unplug the power supply from the outlet for 5. 10 seconds.

When the connection between the iPhone and the network is established, but the error “No connection to the Internet” is displayed on the screen, you should check:

  • An Internet cable that is inserted into the router into the WAN (Internet) socket;
  • The balance of funds to the account of your provider.

If your iPhone is not certified for the Russian Federation (purchased abroad, or from “gray” dealers) or there are many wireless networks in the access area, you can try changing the channel in the router. To do this, you need to enter the settings of the router, where change the region to the USA, and the encryption system from WPA2 / WPA to WEP.

incorrect router settings

If the phone does not see only the home network, but shows other access points in the house / apartment or in other places, the router is probably not configured correctly to work with your phone. Then you need to enter the router control console and double-check the set parameters.

  • Make sure the mobile tethering function is activated. To do this, open the section “Wireless network settings”, the name of the item differs from manufacturer to manufacturer. It is important to check the boxes next to “Enable wireless router broadcast” and “Enable SSID Broadcast”.
  • Change your network mode to a less modern standard, such as 11b or 11g. Since some phones are equipped with outdated standards and do not always see the Wi-Fi network, with new standards.
  • Also change the region, channel and channel width if the above recommendations are ineffective.

Why the phone does not see the WI-FI network

Problems affecting the display of access points are conditionally related to problems:

  • On the mobile device side.
  • On the side of the router.

To fix problems with displaying Wi-Fi networks, you need to correctly diagnose the problem. To identify the cause, the best way is to connect another mobile device. If the second smartphone also does not see the wireless network, then the problems are related to the router or incorrect settings. To clarify the latter, it is better to connect to another access point.

frequency range is not set correctly

If a dual-frequency Wi-Fi module is installed in the smartphone, the default mode is auto. Thus, the phone detects access points operating at 2.4 and 5 GHz. If the settings are set to work only on one frequency, routers broadcasting a signal on a different frequency will not be displayed in the phone menu.

Check the module operation mode in the phone settings: phone settings. Wi-Fi. advanced settings in the drop-down list. Wi-Fi frequency range. automatic mode.

Reason: breakdown of the Wi-Fi module in the phone

Wi-Fi failures are rare. Usually other modules. Bluetooth and / or GPS. also fail along the way. To identify a breakdown, you should carefully check the settings in the phone and router. Connect with other equipment at 2.4 and 5 GHz. If the change of the firmware / communication module is ineffective, you should contact the service center. Upon confirmation of a module breakdown, the motherboard removed from another device is often replaced for recovery.

Mechanical damage can be avoided if you follow the basic rules for using your smartphone. If you ignore the problems, then because of them others may appear, the level of complexity of which will be impossible to predict.

A few more tips are described in the following

Module malfunctions

The hardware module connects to wireless networks. This detail is considered one of the most problematic in the iPhone. The problems started with the 4s model, where the smartphone did not see Wi-Fi. Usually, the malfunction manifested itself in the course of overheating, falling or getting moisture inside.

In this case, it is recommended to give the cell phone to a specialist, but if you have the appropriate skills, you can fix it yourself.

So, what to do if the iPhone does not see the network at home or any other Wi-Fi:

  • Turn off your smartphone and remove the case.
  • Unscrew the screws on the housing.
  • Remove the cover and unscrew the additional 4 bolts next to the camera.
  • Remove the unit and unscrew the screw from the antenna.
  • Use tweezers to pick up the latch and pull it out.
  • Take out the module and warm it up to 300 degrees. This can be done with a hair dryer.
  • Warm up the board. We do not recommend holding the hairdryer over it for a long time.
  • Wait for the machine to cool down and put it back.

The solution to the problem is also relevant for the iPad, which does not see Wi-Fi. The same method can be used if it is necessary to replace a defective part with a new one.

Warming up is a dubious method. Even if you do not completely ruin the gadget, this method usually helps only for a while. Then the problem comes back.

Checking the operation of the router

Relevant if a router malfunction is found. Because of this, no device can connect to the internet via Wi-Fi. This can happen due to power surges or malfunction of some parts.

  • Try restarting your router. If the situation has not changed, then use the second option.
  • Go to your personal account and check the parameters of the router. Login to the settings is done through the browser at (or another, which is indicated on the device itself). Enter your personal password and login from the “admin”. Check if the settings are correct.

If that doesn’t work, then try connecting through another device, such as an iPad. And, if, when trying to connect, the iPad does not see Wi-Fi, then contact the repair service. This is an extreme measure. Maybe it’s time to change your router to a new one.


A factory reset is an effective way to troubleshoot network connection problems. As we already found out, connection failures started a long time ago. The iPhone 4 did not see Wi-Fi, the story continued with the iPhone 5, 6 (they are not being updated at the moment). The latest versions have eliminated these problems. If you are the owner of previous models, then the reset operation will help.

Make sure to back up your data, otherwise it is almost impossible to recover information.

  • go to the menu;
  • find the item “Settings”;
  • select “Reset”;
  • click “Reset settings”;
  • wait until the end of the operation.

Additional ways to troubleshoot problems

Other troubleshooting methods that we will look at can be considered universal and provide answers to the questions that have arisen, why the iPhone does not see the Wi-Fi network. Let’s analyze the most popular.

What to do if Wi-Fi is not working on iPhone 4S

Problems with the Wi-Fi module in most iPhones of the 4th series are congenital. the phone is equipped with either simply unreliable or completely defective hardware. In most cases, the module either overheats, or its problem lies at the firmware level.

However, in versions 7.1 of “apple” software, the cause of bugs is 100% iron. If you have already encountered this, then most likely you have already asked Google what happened. As a rule, the Internet prompts the only solution. to carry it to the service center. But practice shows that such radical methods should not be resorted to right away.

Disconnecting iPhone during a call: finding and fixing the cause

Hard Reset

If the temperature experiments did not help you, and Wi-Fi still does not work, we begin to scoff at the software part of the gadget. The easiest thing to do with it is to restart the hardware. The “turn on / off the iPhone 4s itself” method will not help here. Press the “Home” button at the same time (at the bottom under the screen, there is only one) and the shutdown button (on the upper end of the case) and hold them for 4-5 seconds. Is it out? Everything is fine, turn on, check.

The second way to Hard Reset is through the iTunes application. We connect the iPhone to the computer. iTunes will greet us with a message that a new device has been found. In the same window, you can find out the version of its firmware and find the “Restore and update” button. Click. We wait. Did not help? Go ahead.

Repairing the module with a hair dryer

The solution to the problem, as often happens, was suggested by the users of the YouTube video hosting. If you are loyal enough to the possible consequences. look right away.

If you have no desire to watch, then we will explain. The two methods described in the video help you to “set the brains” of the hardware of your iPhone. We are looking for a hairdryer in the house. Found it? We turn on and arrange for the experimental 4s to warm up. The methods differ in that in the first case we do not need to disassemble the phone (the life span after treatment is from one to three months), in the second case we disassemble the iPhone and it is the module that we warm up (the life span after treatment is much longer than three months).

The main thing in this process is not to overdo it. Diligence is, of course, commendable, but having exceeded the critical temperature, we can confidently carry our 4th iPhone for repair. And it can come out even more expensive than it could be.

After warming up, let the phone cool down to normal temperature and turn it on, checking our result. How is it in your case? It worked? The guys on the video worked it out, so the way has a place to be.

And if the firmware?

Some users note that Wi-Fi stopped working after switching to iOS 7. Then, most likely, you will not have to go to the service at all, but you will have to refuse the update either.

A warning! Before using the method described below. make a backup of your personal data from your phone.

Made? Further. it is easier. We climb into the settings. Find the “Reset” menu and select “Reset all settings”. iPhone will be restored to factory condition. How to do it. shown in the screenshots below.

If none of the described resuscitation methods solved the problem of connecting the iPhone 4s to a Wi-Fi network, there is no way out. you will have to carry it to a service center. However, you can console yourself with the thought that you did the best you could.
