Tips To Fix The WiFi Disconnection Issue On iPhone

Note – Some of these tips may require you to reset the iPhone, so do make sure to keep a backup of your device on iCloud or Mac. This way, you will not have to face the trouble of losing all your data.

Alright, have a look at the tips below and follow the given steps accordingly.

1. Check the network signal

The network signal strength is one of the essential factors in providing a consistent internet experience to the users. If the router is outdated or has some issues, you will never be able to access WiFi internet at its optimum speed.

Also, if you try to access the same network from a long distance, you might see a significant drop in signal or complete disconnection on the device.

This behavior leads to the infrequent connection on your iPhone, which makes it difficult to receive updates from social media apps, news apps, etc. You might even miss out on some internet calls if the connection drops as soon as you lock the iPhone screen.

To fix the issue, you check out the following ways through which you can test the strength of your WiFi’s signal on iPhone.

  1. Test the signal on a different device using the same WiFi network.
  2. Try out a different WiFi network.

Both these options can help you determine the fault in your device or WiFi router.

For many users, this simple tip has helped fix their problem with WiFi network. So, do follow the above steps before heading to any other solution.

2. WiFi login details on iPhone

WiFi network settings play an important role in allowing users to use the stable internet service on iPhone.

However, if you have added inappropriate details to the settings field, you might face some issues with your internet. And you will need to change these details as soon as possible to avoid any network interruptions.

You can contact the service provider to get the appropriate settings details. They may also help you in answering your queries related to this issue.

3. Toggle Airplane Mode

Airplane mode is a great tool to shut off various networking services on iPhone. These services include carrier signal, Bluetooth, WiFi signal and the cellular data signal.

You can use this feature to enable and disable the WiFi network on your device.

  1. Swipe up the Control Center and tap the Airplane Mode icon.
  2. Wait for a few seconds and tap the same icon again.

This quick action will force the WiFi router to reestablish a new connection with your device, which should help in dealing with the WiFi disconnection problem.

4. Restart your iPhone

Another simple trick!

Yup, restart your iPhone and see whether the WiFi network remains stable for some time.

If there is any network glitch from ISP’s side, the restart trick should help you resolve it completely.

Note – This trick may not work effectively if your iPhone keeps disconnecting from WiFi all the time.

5. Turn off WiFi Assist feature

This feature lets you use Cellular Data service if you’re having issues with the WiFi connectivity.

It means whenever your WiFi network loses its signal strength, the Cellular Data service will take its place to complete the remaining tasks like downloading updates, receiving new files/social media updates, etc.

To avoid such situation, you will need to disable this feature altogether.

Follow these steps to turn off WiFi Assist on iPhone –

  1. Go to the Settings app.

6. Change WiFi network settings on iPhone

Just a little-advanced step!

Here, you will have to change a few network settings to be able to resolve the WiFi drop problem on iPhone.

So, let’s begin. Take a look at the following steps to get into these advanced settings –

  1. Go to the Settings app.
  2. Tap Wi-Fi.
  3. Tap the (i) icon to open the advanced settings.

When you’re inside this panel, you can play with different settings to address the disconnection problem.

Forget This Network

This option lets you forget the settings, which means your iPhone won’t remember this network and login details when you try to access again.

You will have to look for this same network to get the internet access next time. Apart from this, you will also need to provide login details to establish the connection.

IPv4 Address –

Well, you don’t have to change anything here. Just use the configuration settings provided by your ISP.

Generally, the IP settings provided by ISPs are good enough to establish the connection between your device and their servers.

If you still want to change these settings, don’t forget to take a screenshot of old settings or write those details down somewhere.

Renew Lease

Although you might not notice any significant change after performing this step, it can help you renew the expired lease period.

To perform this option, you will have to tap the ‘Renew Lease’ option in the same panel.

Configure DNS

DNS configurations can make or breaks things as far as your internet connection is concerned.

If you’ve added wrong DNS addresses to the configuration fields, you will have a difficult time accessing the same network. Even a single-digit mistake in the IP address can prevent you from internet access.

Under the Configure DNS option, you will see the following two options –

iPhone DNS options

The Automatic option allows your iPhone to detect ISP-provided IPs, which automatically connects your device to the network servers.

On the other hand, the Manual option gives you the freedom to use third-party DNS addresses as per your choice.

If you feel your ISP’s service is slow, you can test Google’s DNS address for a few days or weeks.

For this purpose, add the following IP addresses to the DNS settings –


Once you add the DNS servers to the configuration settings, restart your iPhone and try using your WiFi connection on different apps.

Note – For those who don’t know, there is no harm in using trusted third-party DNS servers like Google’s DNS. And these types of servers may also offer better speed and connectivity than your local service provider.

7. Turn off Cellular Data option

As you know, you can use internet services using WiFi as well as Cellular data.

So, if you think your iPhone keeps having issues with WiFi, you can try disconnecting cellular data. It will force your device to rely on WiFi-only mode.

Now, when you lock the iPhone screen, it won’t disable WiFi connection to save some battery life. You will still receive regular updates on your screen.

Many users have noticed this behavior on their devices, so it’s worth checking on your device too.

Note – If you don’t receive updates when the screen is locked, your device might have radio signal related issues. It’d be a good idea to get your examined by Apple folks.

8. Reset Network Settings

Tried everything? Nothing worked?

Well, the last thing you can do is reset the network settings on your iPhone. The reset option will allow you to remove all old network settings entirely.

Here’s how you can perform the steps –

  1. Open the Settings app.
  2. Tap General and scroll down to select the Reset option.
  3. Tap Reset Network Settings.
  4. Enter the passcode to reset these settings.
