My iPhone Can't Connect to My Wi-Fi

By Carol Finch

Learn how to troubleshoot an iPhone that won't connect to a Wi-Fi network using connection and settings fixes.

When your iPhone won't connect to Wi-Fi, the cause is probably either a connection and a settings problem, and you may need to try several troubleshooting fixes before you are back online.

Check Airplane Mode and Wi-Fi Settings

Tap Settings. If the Airplane Mode button is green, tap it to turn it off. This mode disables wireless functions, so switching it off may restore your connection. Check that Wi-Fi is on. If it is off, tap its button to open the settings screen and tap Wi-Fi to turn it on.

Enter the password for the Wi-Fi account, if prompted, and wait to see if the iPhone connects. If you can't change the Wi-Fi button or if you see an incorrect password error message, even though you're using the correct key, move on to other troubleshooting fixes.


  • Turning Airplane Mode and Wi-Fion and off again refreshes your iPhone's connections and may fix aglitch. If Airplane Mode is off, turn it on and off again. If the Wi-Fibutton is on but the connection doesn't work, turn it off and onagain.
  • If you don't know thepassword for your home network, it may be printed on the bottom orside of your router.

Check Your Devices

Check if the Wi-Fi network is working on a computer or other device. Make sure your networking devices — router and modem or combo boxes — are turned on, that all cables are connected correctly and that you're close enough to the router to pick up a signal.

If the network connection is not working on your computer or other device, power down the networking devices, wait a couple of minutes and turn them on again to see if you can connect. If you can't connect any device to the network, you may have an outage.

If the connection is working, power down the iPhone to reset it. Hold the Sleep/Wake button and swipe the shutdown slider when it shows on the screen. When the iPhone closes down, hold down Sleep/Wake to restart it. If this doesn't reset the connection, switch off or unplug all networking devices, wait a couple of minutes and restart them.


Check that your iPhone's operating system is up to date and install iOS updates if available.

Remove the Wi-Fi Network

Remove the Wi-Fi network from the iPhone and reinstall it. Before you do this, make sure you know the network's password — you need this to set up the network again.

Open Settings and then Wi-Fi. Tap the network you want to remove.

Tap the network name to open its settings page.

Tap Forget This Network and select Forget on the confirmation window.

The iPhone removes the network from its system when you tap Forget.

Go back to Wi-Fi and select the network from the Choose a Network list. Type the network's password in the Password box and select Join.

Select Join to add the network to the iPhone again.

Wait for the iPhone to reconnect to the network and check to see if you have a signal. If not, reset your network settings.

Reset Network Settings

Resetting network settings on an iPhone removes all current data, rolling the system back to default networking settings. Note that you lose saved passwords and keys when you reset, so make sure you know any passwords you'll need to rejoin networks later.

Tap Settings, open General and tap Reset.

Open Reset to access the iPhone's reset options.

Tap Reset Network Settings and enter the iPhone's passcode, if prompted.

How to reset an iPhone's network settings.

Select Reset Network Settings from the confirmation window.

Resetting network settings may clear iPhone connection glitches.

Wait for the iPhone to restart and try to connect to the Wi-Fi network.

If you still can't access Wi-Fi, try connecting your iPhone to another network. If it connects, you may have a network problem and should contact your Internet company. If the iPhone won't connect with any Wi-Fi network, contact Apple for support.
