Troubleshooting an iPhone 11 Pro that keeps disconnecting from Wi-Fi network

When dealing with Wi-Fi issues on your iPhone, you’ll need to consider ruling out several factors from the main internet source down to the system aspect of the affected device. For as long as the underlying cause is from your end, the chance of fixing the problem is higher. To give you some input, I’ve mapped a few handy tweaks to deal with random Wi-Fi problems, particularly those depicted by Wi-Fi drops on your new iOS device. Don’t forget to test your internet connection after carrying out each solution to determine whether or not the problem is addressed. If none of these helps, then you may  have to consider opting for service. But before doing so, try applying these subsequent methods to eliminate common causes of Wi-Fi drops on your iPhone 11 Pro.

First solution: Power cycle the wireless router or modem.

Most internet service providers would recommend this method first, if not last, when internet connectivity issues arise. In this process, internet symptoms inflicted by random firmware crashes on the network equipment are eliminated. Thus, if you are near the modem or wireless router right now, follow these steps to power cycle it first:

  1. Turn off your modem/router by pressing its power button.
  2. While the device is powered off, unplug its AC adapter from the power source. Keep it that way for about 30 seconds to 1 minute.
  3. After the elapsed time, press the power button to turn it back on.
  4. Wait for all the light indicators, particularly the Wi-Fi signal indicator to become stable.

If by any chance, the Wi-Fi signal indicator on the wireless router/modem appears in red color and that doesn’t change after power cycling the network device, contact your internet service provider to verify the status of your internet and account. If there’s no ongoing outage and your account status is good, check the cable connection from the modem/router to the main internet source. The internet set up however vary depending on how your network is installed by your service provider. If you couldn’t figure this out, then you better have a technician come to your place and inspect your lines as well as the modem or router condition.

Second solution: Reboot your iPhone 11 Pro (soft reset).

Another simple solution to minor internet problems transpiring on an iPhone is a soft reset or reboot. Performing a soft reset not only gives a pause to your device but more importantly, it eliminates any random flaws triggered by minor firmware crashes and app glitches. It doesn’t affect any saved information on the internal memory, so you don’t need to back up files from your iOS device. Just follow these steps to soft reset your iPhone 11 Pro:

  1. Press and hold both the Side and Volume Up buttons for a few seconds.
  2. Release both buttons when the Slide to Power off bar appears.
  3. Swipe or drag the bar to turn your device off.
  4. After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.

Allow your iPhone to finish its boot sequence and then re-establish Wi-Fi signal. If you’ve set it to auto-connect to the Wi-Fi network, then it will reconnect by itself. Otherwise, you’ll have to connect it manually.

Third solution: Turn Wi-Fi off and then back on.

Wireless problems depicted by random Wi-Fi drops can also be remedied by restarting the iPhone’s wireless feature. It’s possible that the Wi-Fi system of your device has become faulty and thus it needs a quick refresh. The easiest way to refresh Wi-Fi internet connection on your iPhone is through the Wi-Fi toggle. Here’s how it’s done:

  1. Tap Settings from your Home screen.
  2. Select Wi-Fi.
  3. Tap the Wi-Fi switch to the OFF position.
  4. After about 30 seconds, tap the switch again to turn Wi-Fi back ON.

You can also refresh your iPhone’s Wi-Fi internet connection and along with other wireless features using the Airplane mode trick. This method has been proven to work wonders by many iPhone owners who have faced various types of internet connection problems with their respective iOS devices. If you wish to give it a try, then here’s how it’s done:

  1. From the Home screen, tap Settings.
  2. Select Airplane Mode.
  3. Toggle the Airplane Mode switch to turn the feature ON. Doing so disables your iPhone’s wireless radios and associated features like Wi-Fi and Bluetooth.
  4. While Airplane Mode is turned on, reboot or soft reset your iPhone to clear out network cache.
  5. After it reboots, go back to Settings-> Airplane Mode menu.
  6. Then toggle the Airplane Mode switch to turn it OFF again.

If the symptom seems to be occurring more often to the point that you could no longer use internet services on your iPhone, there’s a tendency that your Wi-Fi network has been corrupted. In this case, you will need to delete the corrupted network and then set it up as new. Here’s how it’s done:

  1. Go to Settings-> Wi-Fi and make sure that the Wi-Fi switch is enabled.
  2. Scroll down to the list of available Wi-Fi networks.
  3. Select your Wi-Fi network then tap the option to Forget this Network.
  4. If prompted, confirm that you want to forget your Wi-Fi network. After confirming, your network will be deleted from your device. Turn Wi-Fi off and then restart your iPhone.
  5. As soon as your phone boots up, head back to Settings-> Wi-Fi menu and enable Wi-Fi again.
  6. Wait for your Wi-Fi network to show up in the list then select it.
  7. Tap the option to Join or Connect.

If prompted, enter the correct Wi-Fi password to get access to the network. Allow your device to establish a stable internet connection and then see if the problem is gone.

Fourth solution: Update carrier settings to fix your iPhone 11 Pro that keeps disconnecting from Wi-Fi network.

Internet connectivity issues in iOS devices can also be resolved by updating carrier settings. Carrier settings updates are separate updates released by your carrier or internet service provider. These updates are often pushed to bring in some network system enhancements and network bug fixes. Most carrier updates are auto-installed, which means they’re automatically implemented on your device, when available. Others on the other hand, require manual implementation. To make sure you didn’t miss installing some critical network system updates from your ISP, follow these steps to manually check for and install pending carrier updates for your iPhone 11 Pro:

  1. Connect your iPhone to the computer and then open iTunes. Be sure to use the latest version of iTunes app to avoid bumping into some system conflicts.
  2. Wait for your device to sync and back up with iTunes.
  3. Click to select your iPhone 11 Pro when it appears in iTunes.
  4. Navigate to the Summary section and then hold down the Shift key on the keyboard and click Check for Update. Doing so will prompt iTunes to install an iOS image (*.ipsw).
  5. Change the file type to iPhone/iPad Carrier Configuration File (*.ipcc).
  6. Select the desired file and then follow the rest of the onscreen instructions to complete the process.
  7. When the carrier update installation is complete, turn your iPhone off and then disconnect it from the computer.

The recent carrier settings updates will then be implemented, the next time you turn your iPhone back on.

Aside from carrier settings, it is also recommended to keep your device software up to date. If you yet haven’t updated your iPhone software, then you should consider doing this right now. Apple typically releases a new iOS version that contains patch codes that are programmed to eliminate stubborn system bugs affecting various functions of the device. A faster way to check for available iOS update is through your iPhone settings but since your device is enduring some internet problems, it would be better to do it manually through iTunes instead. All you have to do is get your computer ready and then follow these steps to start check for new iOS update to download and install on your device:

  1. Connect your iPhone to the computer using the original USB or Lightning cable.
  2. Open iTunes on the computer and wait for it to recognize and sync with your iPhone. Select your iPhone 11 Pro when it appears on the computer.
  3. Navigate to the Summary section and then click the button to Check for Update.
  4. If an update is available, click the button to Download and Update your phone.
  5. Enter your passcode, if prompted to continue.

Then follow the rest of the onscreen prompts to finish installing the new update on your iPhone 11 Pro.

If you’re using a Windows computer or earlier Mac, be sure to use the latest version of iTunes software to avoid bumping into some system conflicts. If you’re using a Mac running on macOS Catalina, you will use the Finder app instead of iTunes to carry out manual system update installation.

Fifth solution: Reset network settings on your iPhone 11 Pro.

Network problems can also be resolved by performing a network reset on your device. This is usually what’s needed to deal with internet problems that are attributed to invalid network configuration on the device.

  5. Enter your passcode if prompted to continue.
  6. Confirm action by tapping on Reset Network Settings again.

Your iPhone will now start erasing your current network settings including personal network preferences. All saved Bluetooth devices, Wi-Fi networks and other data settings will be erased but it the internal data and personal information saved on your iPhone storage won’t be affected.

Last resort: Erase your iPhone and restore its factory default settings (factory reset).

If none of the aforementioned solutions is able to fix the problem and your iPhone 11 Pro still keeps disconnecting from Wi-Fi network, then what you’re dealing with could be a major internet problem inflicted by complex system errors or corrupted Wi-Fi system on your device. In this case, carrying out more advanced procedures like a factory reset is usually needed. But before you do, be sure to back up all your important files from the internal memory so you would still be able to recover and use them afterwards. You can back up files from your iPhone to a dedicated folder on your computer through iTunes. Just follow these steps if you wish to troubleshoot further and factory reset your iPhone 11 Pro:

  1. Open iTunes on your computer, if you haven’t already.

Wait for the entire process to be completed and then you can proceed with the initial setup process and set up your iPhone as new.

Still having the same internet problem or your iPhone 11 Pro still keeps disconnecting from Wi-Fi network?

For internet problems that could not be resolved by any of the aforementioned solutions, the underlying cause is more likely not from within the affected device but rather with the main server. This is usually the case if a temporary network outage is transpiring in your place. The same thing can happen if account-related issues are present. In this regard, contact your internet service provider to check the current status of the internet server as well as your account status. They can also assist you further in carrying out more advanced troubleshooting procedures to fix recurring internet issues on your device. If all your devices are experiencing the same symptoms and that they’re all connected to one same Wi-Fi network, then there’s also a better chance that the problem is on the wireless network equipment — a modem or wireless router in use. In this case, you can ask your internet service provider to re-provision, if not, reset the network equipment from their end. They do have a dedicated software for remote modem/router provisioning, given that your network equipment came from them or registered on their system.

If you suspect that this is a major iOS problem that needs immediate fix patch, you can escalate it straight to Apple Support for further assistance.
