Q: Trouble turning Wi-Fi on

Hello BeckyBirk,

It sounds like you are unable to turn on Wi-Fi on your iPhone because it is grayed out. I would use the troubleshooting steps in the following article named:

If Wi-Fi is grayed out or dim on your iPhone, iPad, or iPod touch

 

Check if the issue still exists after each step:

1. Make sure that your device has the latest version 
   of iOS. 
2. Tap Settings General > Reset > Reset Network Settings. This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings. 

If you still need help, contact Apple for support and service options.

Thank you for using Apple Support Communities.

All the best,

Sterling
