You know how frustrating it is when your iPhone won't connect to Wi-Fi (especially if you have a monthly cellular data limit instead of an unlimited data plan on your iPhone). Updating the iOS, downloading large files, and streaming music and video are all best done over a Wi-Fi connection.

In most cases, reconnecting your phone to a Wi-Fi network can be accomplished with some simple troubleshooting steps, though in some cases more advanced techniques are needed. Check out the many ways you can fix an iPhone that can't connect to Wi-Fi. Try these solutions – from simple to complex – to reconnect your iPhone to Wi-Fi and get back to high-speed internet access.

Turn On Wi-Fi

Turning on wifi

The first rule of tech support is to confirm the thing you're working on is turned on: You may need to turn on your Wi-Fi.  Use Control Center to turn on Wi-Fi. Just swipe up from the bottom of the screen (or down from the top right, on the iPhone X) and tap the Wi-Fi icon to activate it.

While you are in Control Center, look at the Airplane Mode icon near the Wi-Fi icon. If you left your iPhone in Airplane Mode after a recent trip, your Wi-Fi is disabled. Another tap to disable Airplane Mode and you're back on the network.

Is the Wi-Fi Network Password Protected?

Password protected wifi

Not all Wi-Fi networks are available to the general public. Some, like those at businesses and schools, are reserved for use by only certain people. These networks use passwords to prevent public use. You can tell which networks are password protected because they havelock icons next to them on the Wi-Fi settings screen. 

If you're having trouble connecting to a Wi-Fi network, go to Settings > Wi-Fi to see if the Wi-Fi network has a lock icon next to it. If it does, you can request a password from the network owner or look for an unlocked network.

If you have the password but are still having trouble, tap the name of the network that you can't join and tap Forget This Network on the next screen. 

Now go back to the Wi-Fi settings screen and select the network, enter the password, and tap Join.

Force Restart the iPhone

You'd be surprised how often restarting your iPhone solves the problems that ail it. It's not foolproof, of course, and won't fix deep configuration or hardware problems, but give it a shot.

Hold down the Home button and the Sleep/Wake button at the same time. Continue to hold them until the screen goes blank and the Apple logo appears to restart the device.

If you've got an iPhone 7, 8, or X, the restart instructions are a little different. Read this article to get step-by-step tips.

Update to the Latest iOS

Upgrade software

Mobile devices and operating systems are updated regularly, which can lead to compatibility issues. Apple regularly releases updates to iOS that are designed address incompatibilities.

If you're having trouble connecting to Wi-Fi, check to see if an iOS update is available for your device. If there is, install it. That may solve your problem.

To check for iOS updates:

  1. Tap Settings.
  2. Tap General.
  3. Tap Software Update.
  4. If the screen indicates an update is available for your iPhone, plug the phone into a power outlet and tap Download and Install.

Reset iPhone's Network Settings

Reset network settings

Your phone's Network Settings contain all kinds of information, including connection data and preferences for cellular and Wi-Fi networks. If one of the Wi-Fi settings is corrupted, it can prevent you from getting on the Wi-Fi network.

In this case, the solution is to reset the network settings, although this deletes some preferences and stored data related to connectivity (you may have to ask the owner of the network for the connection data and enter it again). To reset your settings:

  1. Tap Settings.
  2. Tap General.
  3. Swipe to the bottom and tap Reset.
  4. Tap Reset Network Settings.
  5. If you're asked to confirm that you want to reset these settings, do so.

Turn Off Location Services

Turn off location services

Your iPhone does a lot of things designed to make it useful. One of these involves using the Wi-Fi networks near you to improve the accuracy of mapping and location services. This is a nice little bonus, but it can be the cause of your iPhone not being able to connect to a Wi-Fi network.

If none of these suggestions have helped so far, turn off this setting. Doing so doesn't stop you from using Wi-Fi, just from using it to improve location awareness.

  1. Tap Settings.
  2. Tap Privacy.
  3. Tap Location Services.
  4. Swipe to the bottom and tap System Services.
  5. Move the Wi-Fi Networking slider to the Off position.

Restore iPhone to Factory Settings

Restore iPhone to factory settings

If you're still unable to connect to a Wi-Fi network, you may need to take a drastic measure: restoring your iPhone to its factory settings. This deletes everything from the iPhone and returns it to its out-of-the-box pristine condition.

Before you do this, make a complete backup of all the data on your phone. Then, wipe your iPhone clean by following these steps:

  1. Tap Settings.
  2. Tap General.
  3. Swipe to the bottom and tap Reset.
  4. Tap Erase All Content and Settings.
  5. You'll be asked to confirm that you really want to do this. Confirm and proceed with the reset.

When the reset is complete, you'll have a fresh iPhone. You can then either set it up as a new iPhone or restore from your backup. Restoring from backup is faster, but you may restore the bug that prevented you from accessing Wi-Fi in the first place, so setting it up from scratch may be best.

At this point, if your iPhone still can't connect to Wi-Fi, it may have a hardware problem. Hardware problems are best diagnosed and repaired by a designated Apple service provider. Take your iPhone to your nearest Apple Store for a checkup or contact Apple support online for alternatives.
