wifi button greyed out

Most times that being grayed out means there is damage of some sort to the wifi antenna. Restoring to factory settings and setting up as new is a way to eliminate it being a software issue.

If going to settings>general>reset>reset all settings does not work, make a full backup using your iTunes computer by connecting with a USB cord. Then restore to factory settings and set up as new.

Try going to settings>general>reset>reset all settings (this does not delete data)

Are you using an MDM device? Have you force restarted the device? Have you tried to go to settings>general>reset>reset network settings? Do you have restrictions set?

Make an appointment at your nearest Apple store genius bar for an evaluation.

Take it to Apple for an evaluation.

Posting a screenshot will speed up assistance in some situations.

I’m having the same issue. When I go into settings my WiFi is turned off and when I try to swipe it to on, nothing happens.

I'm having the same issue. I tried doing a factory reset and my button is still greyed out. I have an iphone 8+ purchased directly from apple within the year.

I have force restarted. It worked yesterday briefly but then the phone restarted again automatically and restarting hasn’t worked since. I’ve also reset network settings with no luck. Not sure what an MDM device is.

Also, no restrictions set.

thanks for thinking of that and posting screenshots.
