Unable to turn on Wi-Fi or Bluetooth on iPhone

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.

1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
2. You can return settings to their defaults without erasing your content.
3. 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.

An update…after failing to fix the software issue on my own, I called help and eventually got an online diagnostics test. Was told “probably a hardware problem.” Went to AppleStore and they looked thru the diagnostic test and told me both my iPhone 12 WiFi and BT processors had burned out. They offered to repair the phone for $395.00. Biggest issue is that I cannot be without my phone for a week or two. Got a new iPhone 14 exchanged from my company when I showed them the estimate. It is a vexing problem and I am still not sure what would cause both BT and wifi processors to burn out at the exact same time while leaving the iPhone wireless and main processor intact and working.

This worked for me. I cancelled my VPN subscription, but forgot about it. When I would power on my device it would connect to wifi, but in less than 5 or 10 seconds it would auto disconnect. I tried resetting my network settings. I was about to factory reset my device until I saw this thread. All I did was delete my VPN settings, and everything was good again. Hope this helps someone pulling their hair out like I was.

SOLUTION

I was having these same issues where my wifi and bluetooth were not working and I couldn't even toggle them on and off. I tried putting on airplane mode for a few minutes, reseting my phone, and nothing seemed to work. It felt impossible looking for an answer but I found this guy on youtube and I'm not sure what the difference is when he shows how to reset the phone, but I did it and my bluetooth and wifi are working again! I'm not sure if it's a temporary fix yet or not, but so far it's working.

Here is the quick youtube tutorial link: https://www.youtube.com/watch?v=tJ8P4du60fg

I have done every single thing here. then after I factory reset my phone and was resetting it up. IT WORKED, but then I was re-downloading everything onto my phone and in the middle of that my phone froze. It then reset and turned itself back on and now neither of them work again. I have no idea why and it is ******* me the F off.

Sounds typical of iPhone… I have a 12 Pro… Started with Bluetooth and Wifi… Then the ear speaker… Then the camera… Then the flash light… Waiting to see what is next… I am keeping it for gaming and Using a Data Sim and making calls…
