Q: IPhone won't connect to WiFi...followed all directions...still won't connect. How do I re-connect?

"followed all directions"

so you followed ALL the steps described in these articles?

• iOS: Connecting to Wi-Fi - Apple Support
• If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network - Apple Support
• iOS: Wi-Fi settings grayed out or dim - Apple Support

If so, since it states:

• If someone else set up your network, ask them for help. If you’re using a network at a company, school, hotel, store, or other free Wi-Fi location, find an employee for assistance.
• If you're connected to a Wi-Fi network but you can’t get online, try to use 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 a Wi-Fi network in a different location. If your device can connect, you’ll need to get help with your Wi-Fi network. If it can’t connect to any Wi-Fi networks, contact Apple.
• Update your Wi-Fi router with the latest firmware and make sure the router supports your Apple product. For more information, contact the manufacturer of your router.

• Who set the wifi?
• what other devices did you try?
• what did the internet provider say?
• did you try different wifi locations?

Thanks for taking more time to post your problem and for using Apple Support Communies

Truly yours
