Wifi Greyed out

Hello,

I had a sudden shut down and after reboot my wifi is disabled (greyed out) and Bluetooth doesn’t work too.

I tried resetting network settings, all settings, erased all content, installing the ios again using itunes, restoring phone in dfu mode… Same problem! Any solution?

I am on ios 15.2

Here’s some photos.

iPhone 11 Pro, iOS 15

Hi, thanks for replying.

In fact, i took the iPhone to an apple care center and diagnostics were run on the phone and everything turned out to be ok!

I reviewed the analytics on my phone and it turned out that the iPhone had a full-panic when it shoot down with a bug type error “211” (i can’t understand it). And since the automatic reboot, wifi is disabled

Reset Network Settings: Only network settings are removed.

When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

If the above fails...

Reset All Settings: All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.

Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
You can return settings to their defaults without erasing your content.
If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.

If nothing above works probably it could be your iPhone may have a WiFi radio or antenna problem. In that case, take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support and get the hardware tested and if needed repaired/replaced.
