How to fix an iPhone 8 keeps losing Wi-Fi signal after iOS 13 update

Wireless connectivity issues transpiring from an update are usually due to some minor system glitches that are easily remedied at home. While software updates are intended to serve a good purpose, not all actual outcomes are positive. Hence, various types of post-update problems manifest. Addressed in this context is one of the common post-update problems transpiring on the iPhone 8 following the iOS 13 update implementation. Read on to find out what to do if your iPhone suddenly keeps losing Wi-Fi signal after installing iOS 13.

Troubleshooting an iPhone 8 that keeps losing Wi-Fi signal after updating to iOS 13

Considering that there’s no issue on the network equipment and your iPhone’s hardware components are free from any sort of damage, any of these subsequent solutions will likely be able to resolve the issue. Unless the underlying cause is a complex iOS 13 Wi-Fi bug that requires dedicated fix patch.

First solution: Restart your iPhone (soft reset).

Any device could turn rogue after a major system transition. This usually happens as some apps couldn’t get to adapt with the recent platform changes immediately. In normal instances, the occurring symptoms are just minor thus, they can easily be remedied by basic tweaks. The simplest yet very effective solution to minor post update flaws such as iOS 13 Wi-Fi bugs that caused your iPhone 8 to keep losing Wi-Fi signal is a device restart or soft reset. If you haven’t already, just follow these steps to soft reset your iPhone 8:

  1. Press and hold the Top or Side button until the Power off slider appears.
  2. Drag the slider to the right to turn your phone off.
  3. After 30 seconds, press and hold the Top or Side button again until the Apple logo appears.

Aside from rectifying minor system errors, performing a soft reset on an iOS device also clears out temporary data that are stored as cache. As a result, your device will be able to perform faster and smoother the next time it boots.

Second solution: Perform the Airplane mode trick.

Another simple yet very effective solution to random errors including iOS 13 Wi-Fi glitches is the Airplane Mode trick. It works by simultaneously restarting the phone’s wireless system and thereby eliminates random errors. Here’s how it’s done:

  1. Tap to open Settings app from the Home screen.
  2. Scroll to and tap on the Airplane Mode menu. 
  3. Tap the Airplane mode switch to turn it on. Doing so will disable your iPhone’s wireless radios as well as its Wi-Fi features.
  4. While the Airplane mode is enabled, perform a soft reset on your phone.
  5. Once the phone is finished booting up, go back to Settings-> Airplane mode then toggle the switch to disable the feature. 

Enable Wi-Fi and reconnect to your Wi-Fi network afterwards and see if the problem is fixed.

Third solution: Update carrier settings to fix your iPhone 8 that keeps losing Wi-Fi signal.

Carrier settings are important when it comes to maintaining your phone’s network stability. Any changes to the network settings from the recent iOS update that leads to some faults will then be dealt with by updating your phone’s carrier settings. To check for new carrier updates, your phone must have a stable Internet access. But since it keeps losing Wi-Fi signal after iOS 13 update, you won’t be able to check updates straight from your phone settings. This is when iTunes play a vital role. If you have a computer that has the latest version of iTunes and is connected to the Internet, then you can proceed to these steps to check for and update your iPhone’s carrier settings manually.

  1. Connect your iPhone to the computer using the original USB cable/Lightning cable that came with it.
  2. Open iTunes on the computer.
  3. Wait for the syncing process to complete.
  4. Then click on your iPad Pro icon in the left-side of the screen.
  5. Navigate to the Summary section then hold down the Shift key on the keyboard. 
  6. Then click Check for Update. Doing so will prompt you to install an iOS image (*.psw).
  7. Change the file type to iPhone/iPad Carrier Configuration File (*.ipcc).
  8. Select the desired folder/directory where you want to save the file.
  9. Turn off your device when finished and then turn it back on again.

After rebooting, reconnect to Wi-Fi and see if the signal is already stable. Otherwise, continue to troubleshoot and rule out other culprits.

Fourth solution: Forget Wi-Fi network then add it back.

Wi-Fi networks can also become corrupted from a system update. To make sure this isn’t causing random Wi-Fi disconnects on your iPhone 8, forget the Wi-Fi network and add it back. This will allow your device to connect to your Wi-Fi network just like the first time it does. Just follow these steps when ready:

  1. From your Home screen, navigate to Settings-> Wi-Fi menu.
  2. Make sure that the Wi-Fi switch is turned on.
  3. Scroll down and select your Wi-Fi network.
  4. Tap the information (i) icon next to the name of your Wi-Fi network (SSID).
  5. Then select the option to Forget this Network.
  6. If prompted, enter your passcode to proceed.
  7. And then tap the option to confirm that you want to forget the Wi-Fi network. The Wi-Fi network will then be removed from your device.

If you see any other unnecessary Wi-Fi networks saved on your network directory, forget them all using the above steps so that none of them could cause conflict to your selected Wi-Fi network. Reboot your iPhone after deleting all saved Wi-Fi networks then go back to Settings-> Wi-Fi menu. Set up your Wi-Fi network then enter the correct network password to reconnect.

Fifth solution: Reset network settings.

Network settings errors inflicted by the iOS 13 update can also ruin the entire network functions and might have caused your iPhone 8 to keep losing Wi-Fi signal after the update. If this is the case, then resetting the network settings on your iPhone would be necessary. This will delete all your current network configurations along with any associated errors from faulty network overrides. Just follow these steps if you wish to continue:

  1. From the Home screen, tap Settings.
  2. Scroll to and tap General.
  3. Tap on Reset
  4. Select the option to Reset network settings.
  5. Enter your passcode if prompted.
  6. Tap to confirm that you want to reset network settings on your iPhone.

Performing a network settings reset also resets the Wi-Fi networks and passwords, cellular settings, APN and VPN settings saved on your phone.

Once the reset is finished, your phone reboots on its own and then loads up the default network settings. Observe your phone afterwards and see if the problem is fixed.

Sixth solution: Power cycle the modem/router.

Wireless connectivity issues that occur after iOS update are not always triggered by a software bug. Instead, the main source of the Internet (wireless router/modem) that’s currently unstable could be the underlying cause and the symptoms just happened to occur after installing the iOS 13 update on your iPhone 8. In this case, performing the so-called power cycle on the modem or wireless router will likely be able to fix the problem. Here’s how it’s done:

  1. Turn off the modem/wireless router as you normally do.
  2. While it’s powered off, unplug its AC adapter from the power source and keep it unplugged for about 30 seconds to 1 minute.
  3. After the elapsed time, plug it back in then turn back on.

Wait for a few seconds until all the light indicators on the modem/router become stable and the Wi-Fi signal to become steady.

Last resort:  Restore your iPhone 8 in iTunes.

Update bugs that could not be rectified by the initial procedures are tough enough and therefore requires more advanced solutions. If you’ve reached this point having the same problem on your iPhone 8 that keeps losing Wi-Fi signal after updating to iOS 13, then you may consider opting for an iOS restore. This may be deemed as downgrading but could be the only way to fix the problem on random Wi-Fi signal disconnects for now. You’ve got two restore options to choose from then. One is recovery mode and the other is DFU mode. You can start carrying out a recovery mode first and see how it works.

To get started, connect your iPhone 8 to your Mac or Windows computer using the original Lightning cable. Be sure to remove any other external paraphernalia from your computer’s USB port to prevent any of them from causing conflict. Also close all running applications or programs on your computer to prevent any of them from interrupting iTunes during the restore process. Then follow these steps to put your iPhone in recovery mode and then restore it in iTunes:

  1. When your iPhone is connected, quickly press and release the Volume Up button.
  2. Then press and release the Volume Down button.
  3. Finally, press and hold the Side/Power button until the phone reboots. Continue holding the Side/Power button even when you see the Apple logo.
  4. Then, release the Side/Power button once you see the Connect to iTunes screen. This screen is an indication that your device has entered recovery mode.
  5. Go to iTunes and you should see a message saying that “There is a problem with the iPhone that requires it to be updated or restored.”
  6. Select the option to Restore, then follow the onscreen instructions to restore your iPhone from the recent iOS backup. 

While carrying out an iOS restore can be considered as a downgrade, this can only be the only way for you to get your iPhone 8 Wi-Fi signal working stable again. Aside from a recovery mode restore, you can also resort to the deepest type of system restore, which is called the DFU or Device Firmware Update mode restore. This is usually the last option and potential solution carried out when restoring and repairing a corrupt iOS from a faulty update and/or malware assault. The main downside however is that you’d lose all critical data from your iPhone storage as they will likewise be deleted in the process.
