Determine whether the WiFi problem is your iPhone or your router

It’s easier to troubleshoot WiFi problems if you know what’s causing them. Make sure your router is compatible with Apple products, then:

  • See if other devices can connect to your network (such as your iPad or laptop)
  • See if your iPhone can connect to other networks (such as a friend’s or a local coffee shop’s)

If your iPhone can’t connect to other WiFi networks and other devices can connect to your network, the problem likely lies with your iPhone.

If your iPhone can connect to other WiFi networks, but no devices can connect to your network, the problem might be your router. Try these steps:

  • Power cycle your router: Leave it off for 30 seconds before you power it back on
  • Reset your router: Most routers have a reset button you can reach with a paper clip or pencil. You can reset your router and set it up again to see if that solves the problem
  • Update your router’s firmware: Consult your manufacturer’s documentation for steps

Here are links to popular router manufacturer support pages:

TIP: If your iPhone connects to WiFi, but there is no Internet, contact your Internet service provider to see if there are any service outages.

Rule out wireless interference

Other wireless signals can interfere with WiFi communications between your iPhone and your router. You can rule out wireless interference by:

  • Using your iPhone away from microwaves, wireless cameras and other devices that produce wireless signals
  • Switching to a different WiFi band. For example, you can switch your router from 2.4 GHz to 5 GHz
  • Switching to a different WiFi channel on your router
  • Avoiding physical obstructions between your iPhone and router, including concrete walls and metal objects

How to fix iPhone WiFi issues

If you’ve ruled out your router and wireless interference as culprits, try the following to fix iPhone WiFi issues.

1. Restart your iPhone

Simply restarting your iPhone might fix the problem, especially if a software or connectivity hangup prevents a WiFi connection. You might want to restart your router first, then your iPhone.

2. Toggle WiFi off and on

Browse to SETTINGS > WIFI and toggle WiFi off, then back on. Ensure your iPhone is attempting to connect to the correct network and that WiFi isn’t grayed out (if it is, follow the rest of the steps in this guide).

While you’re in there, it’s also a good idea to turn on Auto-Join if it’s not already enabled.

3. Check Airplane Mode

Airplane Mode disables the WiFi on your iPhone by default, so if you’ve recently traveled or accidentally enabled Airplane Mode, you’ll want to turn it off.

  • Browse to SETTINGS
  • Toggle Airplane Mode off
  • If Airplane Mode is already off, toggle it on and back off. Doing so can sometimes fix WiFi issues

You can also access Airplane Mode from your iPhone’s Control Center by swiping down from the top of the screen (iPhone X and newer models) or up from the bottom of the screen (older models).

4. Update iOS

An outdated operating system can cause WiFi issues, so make sure you’re running the latest iOS version. If not, an update might resolve your problem.

  • Browse to SETTINGS > GENERAL
  • Select Software Update
  • Select the latest iOS version and confirm to install

5. Turn off Location Services

Your iPhone relies on nearby WiFi networks for accurate Location Services. Sometimes, that can interfere with your ability to connect to your own WiFi network. Toggling Location Services off and back on might help.

  • Toggle Location Services off
  • See if you can connect to WiFi
  • Toggle Location Services on

6. Disconnect VPN

Virtual Private Networks (VPNs) can help protect your data when you connect to a public WiFi network, but they can also cause WiFi connection issues. If you use a VPN, disconnect it to see if it fixes the problem.

  • Browse to SETTINGS > VPN
  • Toggle the Status to “Not Connected”

If that fixes the problem, you might need to reconfigure your VPN. Learn more on Apple’s iPhone VPN settings page.

7. Disable WiFi Assist

WiFi Assist is an iPhone feature that automatically uses cellular data for Internet access when you have a poor WiFi connection. It’s enabled by default, but disabling it can sometimes fix WiFi issues.

  • Toggle off WiFi Assist

8. Forget WiFi networks

When you connect to a network, your iPhone stores its name, password and other data so you can quickly reconnect later. However, if there’s a network change, it could prevent your iPhone from connecting with its stored data. The solution is to forget your WiFi network, then re-add it to your iPhone.

  • Browse to SETTINGS > WIFI
  • Tap the Information icon
  • Select Forget This Network and confirm
  • Reconnect to the network

9. Renew lease

Your network assigns each device a unique IP address, including your iPhone. The IP address is temporarily “leased” from the network and automatically renewed after a set interval. Sometimes, something can go wrong with the renewal that causes your network to invalidate your iPhone’s IP address. You can manually renew the lease to fix this problem.

  • Browse to SETTINGS > WIFI
  • Tap the Information icon
  • Select Renew Lease

10. Reset network settings

A network settings issue can prevent a WiFi connection. It can also cause Internet problems even if your iPhone says it’s connected to WiFi. You can reset network settings to erase all connectivity data for WiFi, cellular, Bluetooth and VPNs. Of course, that means you’ll need to set up each connection again, but it might fix your WiFi problem.

  • Browse to SETTINGS > GENERAL > RESET (or Transfer or Reset iPhone)
  • Select Reset Network Settings
  • Reconnect to your WiFi network

11. Factory reset

If none of the above solutions resolves your WiFi issue, you can try resetting your iPhone to factory settings. Doing so could remove any bugs that are preventing a connection. After you reset your iPhone, you can restore it from a backup – but keep in mind that could reintroduce the same problem, so it’s a good idea to see if you’re able to connect to WiFi first.

Create a backup

Normally you need to connect to WiFi to back up your iPhone, but since you can’t, you can take a computer backup via iTunes or, if you have iOS 15, you can back it up using mobile data.

  • Toggle on Back Up Over Mobile Data
  • Tap Back Up Now

Factory reset

  • Select Erase All Content and Settings
  • Confirm your selection

12. Get it repaired

If none of these solutions work, you might have a faulty WiFi antenna or another hardware issue that needs to be repaired. Repair options include:

  • Warranty repair: You can get your iPhone repaired for free if it’s under warranty and you didn’t cause the damage
  • AppleCare+: Apple charges $99 for repairs not covered by warranty
  • Phone insurance: If you have phone insurance through Verizon, AT&T or SquareTrade, you can expect to pay a repair deductible ranging from $125 to $250, depending on your iPhone model
  • Professional repair: Apple charges $399 to $599 to repair uninsured, out-of-warranty iPhones (iPhone X and newer models). Independent repair shops tend to be cheaper
