How to troubleshoot your iPhone's Wi-Fi connection problem

It’s super frustrating when your iPhone won’t connect to Wi-Fi (especially if you have a monthly cellular data limit instead of an unlimited data plan). Not being able to connect to Wi-Fi stops you from doing things like updating the iOS, downloading large files, and streaming music and video.

In most cases, you can fix an iPhone that won’t connect to a Wi-Fi network after some simple troubleshooting steps. In other cases, more advanced techniques are needed. Check out the many ways you can fix an iPhone that can’t connect to Wi-Fi and get back to high-speed internet access.

This article was written using iOS 12 and iOS 13, but the concepts apply to many earlier versions. On earlier versions, the exact steps described below may be slightly different.

Turn On Wi-Fi

Turning on wifi

The first rule of tech support is to confirm the thing you’re trying to fix is turned on. In this case, you may simply need to turn on Wi-Fi on your iPhone. Using Control Center to turn on Wi-Fi is easiest.

Just swipe up from the bottom of the screen (or down from the top right, on the iPhone X, XS, XR, and 11 series) 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 your iPhone is in Airplane Mode (maybe you accidentally left it that way after a recent trip?), your Wi-Fi is disabled. This could be the cause of your problem. Another tap on the icon disables Airplane Mode and you’re back on the network.

Turning on Wi-Fi isn’t so simple if your Wi-Fi menu is grayed out. Learn how to handle that problem in How to Fix Grayed-Out Wi-Fi on an iPhone.

Is the Wi-Fi Network Password Protected?

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 (easy if you’re at a coffee shop, for example) or look for an unlocked network.

If you have the Wi-Fi password but are still having trouble, tap the name of the network that you can’t join, go to Settings > Wi-Fi > the i next to the network name > and tap Forget This Network on the next screen. Then go back to the main Wi-Fi settings screen and select the network again, enter the password, and tap Join.

You might not be able to connect to Wi-Fi if you’re out of range or there’s interference with the Wi-Fi signal. Make sure you’re close to the wireless router when you’re trying to solve this issue.

Force Restart the iPhone


You’d be surprised how often restarting your iPhone solves its problems. It’s not foolproof, of course, and won’t fix serious software or hardware problems. But it’s fast and simple, so it’s usually worth a shot.

How you restart your iPhone depends on what model you have. If you’ve got an iPhone 7, 8, or X, XS, XR, or 11, the instructions are just different enough for each model that you need our step-by-step article on how to restart your iPhone.

If you’ve got an older iPhone model, just 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.

Upgrade software

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 (but remember, these updates are really large, so it’s best to do them when connected to your computer, if that’s an option). 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 Network Settings

Your phone’s Network Settings contain all kinds of information, including connection data for cellular and Wi-Fi networks. If one of the Wi-Fi settings is corrupted, it could prevent you from connecting to Wi-Fi.

In this case, the solution is to reset your network settings. Although this deletes some preferences, sometimes it’s your only option. To reset your network settings:

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

With this done, you may have to ask the owner of the Wi-Fi network for the connection data and enter it again.

Turn Off Location Services

Your iPhone does a lot of helpful things behind the scenes. One of these involves using nearby Wi-Fi networks to improve the accuracy of mapping and location services. This is a nice bonus, but it can be the cause of your iPhone not being able to connect to Wi-Fi.

  1. Tap Settings.
  2. Tap Privacy.
  3. Tap Location Services.
  4. Swipe to the bottom and tap System Services.
  5. Move the Networking & Wireless slider (on some older versions, this is called Wi-Fi Networking & Bluetooth or Wi-Fi Networking) to white/Off.

Restore iPhone to Factory Settings

If you’re still unable to connect to Wi-Fi, 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 original, out-of-the-box 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.

Contact Apple for Tech Support

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