If you are experiencing Wi-Fi problems on your iPhone, you are not alone. Many iPhone users are experiencing the same Wi-Fi problem as you are, and it’s unfortunate. This can be very frustrating, especially if you have things to do with your iPhone at that particular moment. More frustrating is the fact that there are times when your iPhone won’t connect to Wi-Fi even though your Wi-Fi network appears to be working fine.

The main reason isn’t exact, but in most cases, connection problems can occur after an iOS update, or other reasons such as outdated OS, enabled Airplane mode, changes to settings, mistakenly touching a button, wrong network settings, DNS or cache problems. iPhone antenna issues or a software bug can also be one of the reasons.

Well, the good news is there are many ways to fix an iPhone that won’t connect to Wi-Fi, so before you take your device to the Apple store as the solution or replace your router, try any of these working tips below to reconnect your iPhone to Wi-Fi.

How to solve iPhone Wi-Fi problems

First, make sure that your wireless router is on, and you are closer to it. Sometimes your iPhone won’t connect to Wi-Fi if you are too far from the wireless access point. If, after moving within range to the router doesn’t help, try one of the methods listed below.

1. Turn your WiFi on

The first thing to do is confirm that what you’re trying to fix is actually turned on. All you need to do is to turn on Wi-Fi on your iPhone. You should see the Wi-Fi icon on top of your screen, if not, then do the following:

  • Swipe up from the bottom of the screen (swipe down from the top-right if you are using the iPhone X, XS, and XR).
  • Tap on the Wi-Fi icon to activate it.
  • Wait a few seconds for it to connect.

2. Wi-Fi network password protected

Whenever your iPhone doesn’t connect to Wi-Fi, check to see if the Wi-Fi you are trying to connect to is not password protected. Not all Wi-Fi allows access to everyone. Some network owners use passwords to prevent unauthorized users from connecting to them. A password-protected Wi-Fi usually has lock icons next to them. Go to Settings, then Wi-Fi, to check if there is a lock icon next to the Wi-Fi network. If this is the case, it’s best to ask for the password from the network owner or connect to a network that’s not password protected.

3. Turn off Airplane Mode

Another possible reason why your iPhone won’t connect to Wi-Fi could be the Airplane mode. Airplane mode blocks all network connectivity on a device. Check the Airplane Mode icon located near the Wi-Fi icon; you may have accidentally left it on possibly after a recent trip.
