iPhone Unable to Connect to Wi-Fi (10 Proven Fixes)

iPhones are known for their impeccable service. Generally, you can rely on an iPhone to serve you for years without fail. However, that does not mean they do not malfunction from time to time.

A common problem most iPhone users face is their phones failing to connect to Wi-Fi without any good reason. As you continue reading, you will see some of the causes of this phenomenon and what can be done to overcome the problem.

Why Won’t My iPhone Connect to Wi-Fi?

Assuming your phone has not suffered any physical damage, there are various other possible reasons your phone won’t connect to Wi-Fi

The primary reasons are that your Wi-Fi signal is weak. Therefore, the iPhone cannot establish a meaningful connection. Also, you might be too far from the router, thus making it hard for the devices to connect. In such instances, the best solution is to move closer to the router and try reconnecting. 

Sometimes the connection might constantly be dropping due to a service outage. Your provider is probably already aware of the problem and is working on it in such cases. You can confirm by visiting your Wi-Fi provider’s website or calling the customer care desk for any outage information. You can also use their website and social media pages to notify them of an outage in your area so that they can fix it.

Also, double-check that you are using the correct Wi-Fi password. If you are not in control of the Wi-Fi, find who is and ask if they might have changed the Wi-Fi password.

Also, confirm that you are up to date with the Wi-Fi payments to rule out the possibility of being disconnected by your service provider.

Other reasons why your iPhone is not connecting to Wi-Fi are listed below. For every reason, we have also given a potential fix to remedy the situation. 

1. Turn Wi-Fi OFF and then ON

5. Reset Network Settings

6. Check Your Router’s Settings

Apple has a set of recommended router settings for optimal iPhone performance.

You can crosscheck these settings with the ones enabled on your router to confirm if they are the same. If the settings are not the same, update them to match and try reconnecting to the Wi-Fi.

If updating settings fails, try resetting the router and hopefully solve any configuration issues between your router and iPhone.

7. Check for System Updates

Apple usually conducts updates for iOS, improving the phone’s operation and utilities. The updates also fix system errors that might hinder performance.

Therefore, check whether there’s an update available since they have been known to solve such problems.

Do the following check if there is an update

  • Enable cellular data
  • Navigate Settings>General>Software Update
  • Then if there is an update, there will be an option to Download and Install the update. 
  • You are done once you tap on Download and Install>Install Now.

Also, check that your router has the latest firmware version. Follow the user manual for instructions specific to your router. You can also find instructions on updating router firmware on the manufacturer’s website.

8. Disable VPN

VPNs are important, especially for people who prefer anonymity and safety on their internet. Since VPNs handle any data sharing between your phone and the internet, it is possible it also affects Wi-Fi connectivity. 

Some users have reported that their phones can connect after disabling the VPN, and you should try it too.

To disable the VPN, go to Settings then General>VPN & Device Management

Next, tap on the slider to disable the VPN. Remember to restart the phone before checking if the problem is solved.

9. Disable Wi-Fi Assist

Wi-Fi assist is a feature on iOS 9 and later versions that lets your phone switch to cellular data when Wi-Fi is weak or has no internet. The feature is meant to ensure you have an uninterrupted connection to the internet.

However, it can also prevent your phone from joining a Wi-Fi network even if Wi-Fi has reliable strength. Try disabling Wi-Fi assist and check whether your phone can now connect to Wi-Fi.

To disable Wi-Fi, assist open Settings>Cellular then Mobile Data. Then scroll and tap the slider next to Wi-Fi Assist.

Different routers are reset differently; therefore, google your router’s brand name and model for the correct procedure. 


All the suggestions above have been made, assuming you have ensured all cable connections related to the router are properly made. If all the recommended solutions fail, then your device might be damaged. Consider visiting a trustworthy repair shop or an Apple store for professional assistance.
