You can try any of the outlined solutions below if your new iPhone suddenly fails to connect to the Wi-Fi network or experiences unusual internet behaviors after installing a new iOS update.
Troubleshooting iPhone 13 won’t connect to WiFi after updating iOS
Performing the following procedures will help eliminate common factors that can trigger occurrence of random Wi-Fi internet problems on an iOS device like the iPhone 13. The steps portrayed in every given solution are based on the iOS 15.4 interface.
These solutions are likewise applicable when troubleshooting Wi-Fi issues on other iPhone models but the actual user interface may vary between devices and wireless service providers.
Feel free to start whenever you’re all set to troubleshoot your iOS device.
Solution #1: Reboot the iPhone (soft reset).
The first thing you should do if you haven’t already is to reboot the iPhone. Although an automatic system reboot is part of the updating process, a secondary reboot may still be required to clear out any residual errant cache and data.
This is likewise deemed important to refresh all iOS apps and services to adopt the recent system changes.
To soft reset or reboot the iPhone 13, just follow these steps:
- Press and hold the Power/Side button and either Volume buttons for a few seconds and then release when the Power off slider appears.
- Then, drag the slider to turn your iPhone completely off.
- After 30 seconds, press and hold the Side button again until the Apple logo appears.
Alternatively, you can power the device off and then turn it back on again.
This process does not affect any saved data from the iPhone storage so you won’t lose any important files afterwards.
Solution #2: Refresh Wi-Fi.
Aside from rebooting, refreshing the iPhone’s wireless feature is likewise deemed a potential solution to minor internet flaws.
There are many different ways to get this done on an iOS device. The simplest and widely used workarounds are as follows:
A. Turn Wi-Fi off and on.
Disconnecting and reconnecting to the Wi-Fi network can help fix random internet connection errors on the device.
- To do this, head over to your iPhone Settings-> Wi-Fi menu and then turn the Wi-Fi switch OFF and ON.
This is the traditional way to refresh wireless connections and eliminates minor internet flaws.
B. Turn Airplane mode on and off.
Performing the Airplane mode trick is also an option.
- To do so, go to Settings-> Airplane Mode menu and then turn the Airplane mode switch ON. All wireless features and services will be disabled when Airplane mode is turned on. To re-enable wireless services, just turn the Airplane mode switch off again.
These methods give a quick refresh and restarts the phone’s wireless connectivity features.
Solution #3: Forget the Wi-Fi network then add it back.
Deleting the problematic network and adding it back can also address internet connectivity issues tied to a corrupted Wi-Fi network. It’s possible that the current wireless network has been corrupted from the recent update and therefore needs to be re-added.
This is when forgetting and re-adding the Wi-Fi network is recommended.
And here’s how it’s done on the iPhone 13:
- Go to Settings.
- Tap Wi-Fi. Make sure that the Wi-Fi switch is turned on.
- Tap the information (i) icon next to the name of the Wi-Fi network that your iPhone is connected to.
- Tap Forget this network then tap Forget to confirm action.
The network will be deleted and your iPhone gets disconnected from Wi-Fi.
If there are any saved Wi-Fi networks that you’re no longer using, be sure to forget them all so that none of them would cause conflicts with the current network.
Just repeat the same steps to forget other unused networks from the Wi-Fi menu.
After forgetting the network(s), reboot your iPhone to clear system cache and to refresh iOS services.
As soon as it boots up, go back to Settings-> Wi-Fi menu then re-add and reconnect to your Wi-Fi network.
If your device is still unable to connect, try switching to another Wi-Fi network available.
Solution #4: Reset network settings.
If the recent system update automatically alters or overrides the current network settings of your phone, chances are that the recent overrides have resulted in some conflicts and eventually ruins the Wi-Fi system.
To clear this out, performing a network settings reset is recommended.
To do this, you will need to trigger the reset network settings command on the iPhone with these steps:
- From the Home screen tap Settings to open the Settings app.
- On the settings app menu, tap General.
- Tap Transfer or Reset iPhone to continue.
- On the next menu, tap Reset.
- Then, tap Reset network settings from the available reset options.
- Enter your device passcode if prompted.
- Read the final warning then tap Reset settings to confirm.
The phone restarts automatically when the reset is finished so don’t do anything that may interrupt the process.
As soon as it boots up, reconnect to the Wi-Fi network and see if it’s already working as intended.
Solution #5: Reset all settings.
If the reset network settings command doesn’t solve the problem, the next option you can try is to reset all settings.
This will delete all recent custom changes made to the iOS apps including any errant overrides from the recent software update.
To reset all settings on the iPhone 13, just follow these steps:
- Tap Settings from the Home screen to open the Settings app.
- On the settings app menu, tap General.
- Tap Transfer or Reset iPhone to continue.
- On the next menu, tap Reset.
- Then, tap Reset all settings from the available reset options.
- Enter your device passcode if prompted.
- Read the final warning then tap Reset settings to confirm.
Again, wait for your phone to finish resetting all settings and then reboot on its own. After rebooting, all original settings and app defaults are restored.
This means the need for you to re-enable necessary features that are disabled by default and set default apps for certain file types and data protocols.
This process does not affect any user data so all your saved apps, files and documents won’t be deleted.
Still unable to connect to Wi-Fi?
Random internet issues including those transpiring from an update are typically addressed by the above solutions unless the underlying cause is more complex. If your iPhone is still unable to connect to Wi-Fi, then you may have to resort to other methods that would rule out other possible causes.
Here are a few remaining options you can try on should you wish to troubleshoot further.
1. Power cycle the modem/router.
The very first suggested solution given by most ISP’s technical support to subscribers who are facing various types of wireless internet problems is a modem/router reboot (power cycle).
This simple method turned out to be a very effective solution to random internet problems attributed to minor firmware glitches on the wireless equipment. So if you haven’t already, you may consider this among other last options.
To do this, power off the modem/router and then unplug it from the power source. Keep it unplugged for about 30 seconds to 1 minute. After the elapsed time, plug it back in and wait until it’s finished rebooting. Restart the phone and give it enough time to re-establish wireless connections and connect to the Wi-Fi network.
A temporary solution if this appeared to be an isolated problem with Wi-Fi networks is to go online via Cellular data network.
Just be mindful of your data usage though to prevent incurring additional charges for exceeding your monthly data plan.
If you’re on prepaid, make sure that you have sufficient data credits and your phone must have strong and stable cellular network reception.
2. Restore your iPhone.
Performing the above solutions is usually enough to rectify minor post-update Wi-Fi system errors that cause unexpected internet connectivity issues on an iPhone.
If the problem continues, then it could be a complex wifi network system issue that requires more advanced solutions.
Should you wish to troubleshoot further, the next option you’ve got would be an iOS restore via settings factory reset or iTunes restore.
Restoring an iPhone via factory reset or iTunes restore deletes everything from the device including downloaded apps, custom settings, contacts, multimedia files and other saved data from the iPhone storage.
Afterwards, you may opt to restore your device from a previous iOS backup (if available) or set it up as a new device (fresh install).
Seek more help
If all else fails to fix the problem, contact your internet service provider for further assistance. Your Internet service provider will usually work on the wireless setup and the network equipment in use. Should this be found to be a modem/router issue, you can ask your service provider to refresh or reset the modem remotely.
Also check and confirm if there are any unexpected technical difficulties affecting the ISP’s network services, resulting in a network outage. Unfortunately, for Wi-Fi issues tied to network outages, there’s not much that can be done on the user’s end but to wait until the outage is fixed and the service is back up and running properly again.
You may also escalate the problem to Apple Support given that it instigated from a recent iOS update. This might be an unforeseen iOS bug that requires a dedicated fix patch.
