iPhone 12 Disconnects From WiFi? Here’s the fix

In this troubleshooting guide, we will show you what you can do if your iPhone 12 disconnects from WiFi and determine the cause as to why such a problem occurs. That’s the best way to prevent it from happening again in the future.

A high-end device like the iPhone 12 shouldn’t have any issues connecting to a Wi-Fi network or any network for that matter. However, problems like this occur every now and then and while it’s so annoying, it’s actually not that serious of an issue. 

Needless to say, you will be able to fix this problem if you’ll do some basic troubleshooting, provided that there’s no problem with your network device or your iPhone itself. With that being said, here’s what you need to do about it: 

First solution: Restart your devices


Perhaps it’s just a minor issue with your router or the firmware of your iPhone. So the first thing that you need to do is to restart your devices to refresh their memories. In the case of your router, all you have to do is power it off for a minute or two and turn it back on. For your iPhone, it’s better to do the Forced Restart or simulated battery pull as it’s more effective. Here’s how you do those things: 

  1. Unplug your modem or router from the wall outlet or simply disconnect the power cord from the main unit. 
  2. Leave it without power for a minute or two. 
  3. While waiting, quickly press and release the Volume Up button, and then the Volume Down button. After releasing the volume down button, press and hold the Power key until the logo shows.
  4. Now plug the power cord of your network device back into the wall outlet, or reconnect the cord to the main unit.
  5. Wait for the device to become online and your phone to finish rebooting, and then reconnect to the network. 

More often that not, this procedure will fix the WiFi disconnection issue on your iPhone 12. However, if it still disconnects from your network after doing this, then move on to the next solution. 

Second solution: Reset the Network Settings of your iPhone

After rebooting your network device and your iPhone and the latter still disconnects from the network, the next thing that you have to do is reset the network settings of your phone. But that is if your other devices can connect to the same network without dropping their connection. 

By resetting the network settings, you’re actually reloading all the network services on your device. If this problem is caused by one of the network services that failed, then this should fix it. Here’s how it’s done: 

  1. From the Home screen, tap Settings. 
  2. Tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Touch Reset Network Settings. 
  5. If prompted, enter your security lock. 
  6. Tap Reset Network Settings at the bottom of the screen. 

After doing this, allow your iPhone 12 to reconnect to the same network and see if it still disconnects on its own. If it still does, then move on to the next solution. 

Third solution: Factory reset your iPhone 12

Assuming only your iPhone 12 has this problem and the first two solutions failed to fix it, the next thing you have to do is to do the Factory Reset. But before that, you may also have to check if there’s a new update available because if it happens to be a widespread problem, Apple will immediately roll out a patch through an update. 

Prior to the reset, make sure to create a copy of your important files and data as they will be deleted. When you’re ready, follow these steps to reset your iPhone: 

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Tap Erase All Contents and Settings. 
  5. Tap Erase Now. 
  6. If prompted, enter your security lock. 
  7. Tap Erase iPhone at the bottom of the screen.  
  8. Tap Erase iPhone again to proceed.  
  9. Now enter your Apple ID password, and then tap Erase to proceed with the reset. 
  10. Wait until your iPhone has finished the reset, and then set it up as a new device. 

Should the problem continue even after updating your iPhone 12 and doing the factory reset, then you should consider contacting your Internet Service Provider and have your router checked or replaced. Or you may also need to get your iPhone checked by an Apple technician. 

And that’s what you need to do if your iPhone 12 disconnects from WiFi network. We hope that this troubleshooting guide has been able to help you.
