How to Fix WiFi Not Working Issue on Your iPhone Device

Key Takeaways:

  • Most iPhone WiFi issues can be resolved by toggling settings or restarting your device and router
  • Updating to the latest iOS version and resetting network settings often fixes more persistent WiFi problems
  • Hardware issues are rare but may require contacting Apple Support or visiting an Apple Store for repair

If you’re experiencing WiFi connectivity problems on your iPhone, you’re not alone. Many iPhone users have reported issues with their WiFi not working properly, especially after updating to iOS 17[1][2][10][18]. As someone who has personally dealt with iPhone WiFi troubles and helped numerous friends and family members resolve theirs, I can attest to how frustrating it can be when your iPhone won’t connect to a WiFi network.

Fortunately, most iPhone WiFi issues can be fixed relatively easily by adjusting some settings or performing a few simple troubleshooting steps. In this comprehensive guide, I’ll walk you through the most effective methods for getting your iPhone connected to WiFi again, starting with the quickest and easiest fixes.

Toggle Airplane Mode

One of the first things to try when your iPhone won’t connect to WiFi is to toggle Airplane Mode on and off. This quickly resets your iPhone’s wireless radios, which can sometimes resolve network connection glitches[7][19].

Here’s how to do it:

  1. Open the Control Center by swiping down from the top-right corner of your iPhone’s screen
  2. Tap the Airplane Mode icon to turn it on
  3. Wait about 10-15 seconds, then tap the Airplane Mode icon again to turn it off

After disabling Airplane Mode, try connecting to the WiFi network again.

Restart Your iPhone

If toggling Airplane Mode doesn’t do the trick, the next step is to restart your iPhone. Restarting clears out minor software bugs that could be interfering with your WiFi connection[3][7][12].

For iPhone X and later:

  1. Press and hold the Side button and either Volume button until the power off slider appears
  2. Drag the slider to power off your iPhone
  3. After your iPhone shuts down, press and hold the Side button again until the Apple logo appears

For iPhone SE, 8, 7, or 6:

  1. Press and hold the Side (or Top) button until the power off slider appears
  2. Drag the slider to power off your iPhone
  3. After your iPhone shuts down, press and hold the Side (or Top) button again until the Apple logo appears

Restart Your Router

If your iPhone still won’t connect to WiFi after restarting, the issue may be with your wireless router rather than your iPhone. Try restarting your router by unplugging it, waiting about 30 seconds, then plugging it back in[3][6][8].

It’s also a good idea to make sure your router’s firmware is up-to-date, as outdated firmware can cause performance and connectivity issues. Check your router manufacturer’s website for instructions on updating the firmware.

Forget and Rejoin the WiFi Network

Another effective troubleshooting method is to have your iPhone “forget” the problematic WiFi network, then rejoin it. This can resolve issues caused by outdated or corrupt network configurations[7][20].

To forget a WiFi network:

  1. Open the Settings app and tap “WiFi”
  2. Tap the info icon next to the WiFi network you want to forget
  3. Tap “Forget This Network”, then confirm by tapping “Forget”

After forgetting the network, go back to Settings > WiFi and select the network from the list to rejoin it. You’ll need to re-enter the WiFi password.

Update to the Latest iOS Version

If you’re still having trouble connecting to WiFi, check to see if there is an iOS update available for your iPhone. Apple frequently releases updates that include bug fixes and performance improvements[4][19].

To check for an iOS update:

  1. Open the Settings app
  2. Tap “General”
  3. Tap “Software Update”
  4. If an update is available, tap “Download and Install”

After updating to the latest iOS version, try connecting to the WiFi network again. Many users have reported that updating from iOS 17 to 17.0.1 or 17.0.2 resolved their WiFi issues[1][2][10].

Reset Network Settings

If none of the above steps have restored your iPhone’s WiFi functionality, the next thing to try is resetting your network settings. This will erase all your saved WiFi networks and passwords, as well as cellular and VPN settings, but it can resolve stubborn connectivity issues by eliminating corrupt settings[3][5][11][19].

To reset your iPhone’s network settings:

  1. Open the Settings app
  2. Tap “General”
  3. Tap “Transfer or Reset iPhone”
  4. Tap “Reset”
  5. Tap “Reset Network Settings”
  6. Enter your iPhone passcode to confirm

After your iPhone restarts, you’ll need to re-enter the passwords for any WiFi networks you want to join.

Disable WiFi Networking Services

Some iPhone users have found that disabling WiFi Networking under their Location Services settings resolved WiFi connectivity and speed issues[6][16][19].

To disable WiFi Networking services:

  1. Open the Settings app
  2. Tap “Privacy” (or “Privacy & Security”)
  3. Tap “Location Services”
  4. Scroll down and tap “System Services”
  5. Toggle off “Networking & Wireless” (or “WiFi Networking”)

You can turn this setting back on if it doesn’t resolve your WiFi issues.

Contact Apple Support

If you’ve tried all the troubleshooting steps above and your iPhone still won’t connect to WiFi, there could be a hardware issue with your iPhone’s WiFi antenna or other components. In this case, it’s best to contact Apple Support or visit an Apple Store or Authorized Service Provider for further assistance[3][7][16][19].

Before setting up a support appointment, make sure to back up your iPhone. If possible, also try connecting to a different WiFi network to determine if the issue is specific to a particular network or happening on all WiFi networks.


While it can be incredibly frustrating when your iPhone won’t connect to WiFi, most issues can be resolved by working through the troubleshooting steps outlined above. In my experience, toggling Airplane Mode, restarting the iPhone and router, forgetting and rejoining the WiFi network, and resetting network settings are the most effective methods.

If your WiFi woes started after updating to a new iOS version, updating again to the latest version or waiting for Apple to release a fix is likely the solution. And although hardware-related WiFi failures are uncommon, it’s best to get your iPhone checked out by Apple Support if the problem persists after you’ve exhausted all the DIY troubleshooting options.
