Hey Brianasurfergirl,
If your Wi-Fi is grayed out, these are the recommended steps:
- Verify that airplane mode is off by tapping Settings > Airplane Mode.
- Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
- Ensure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
- If your issue is still unresolved, perform a software restore in iTunes.

I crossed off the one you had already mentioned doing. I would start off with these and see if it resolves both the Wi-Fi issue and the cellular issue as well.
Take care,
