If you can't connect to Wi-Fi on your iPhone or iPad
Check your Wi-Fi settings, router, and other issues with your network.
Before you get started
Go to Settings > General > Software Update, and update to the latest software.
Check your Wi-Fi settings
If you can't connect to Wi-Fi, go to Settings > Wi-Fi to make sure that your Wi-Fi is on. Tap your network name to join the network, and look for a blue checkmark to confirm you're connected.
If you still can't connect, go back to Settings and make sure Airplane Mode is off. Then scroll down to Cellular, and make sure Wi-Fi Assist is off.
If the Wi-Fi setting is greyed out, restart your device.
If you still see a message like "No Internet Connection," there might be another issue. Check your router and network settings.

Check your Wi-Fi router
Update your router with the latest firmware and make sure the router supports your Apple product. If you need help, contact the router's manufacturer.
Make sure that your router is turned on and in range—you might be too far from the signal. If your router supports separate frequencies, try joining another frequency—for example, join 5 GHz instead of 2.4 GHz.
If needed, restart your router and cable or DSL modem by unplugging the device and then plugging it back in.
Reset your network settings
If you want to reset your network, go to Settings > General.
Scroll down and tap Transfer or Reset [device], then tap Reset. If your network is configured to be used in a school of business, consult with your IT administrator before you reset the network.
Tap Reset Network Settings. This resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.

Get more help
If you're connected to a Wi-Fi network but can’t get online, try your Wi-Fi network on other devices. If you can't get online using your other devices, there might be a service outage. Call your cable company or internet provider for help.
Try connecting to Wi-Fi in a different location, to see if you have an issue with only your own Wi-Fi network. If your device can't connect to any Wi-Fi network, contact Apple.
