Fix 2: Restart Your iPhone
There is a lot that goes on behind the scenes while we use and interact with our phones. Thousands of background processes from various apps installed on our phone can sometimes temporarily break a few things, causing issues like your iPhone 12 disconnecting from WiFi. The simplest way to ensure your phone starts functioning properly is to reboot it.
You can power off your iPhone by holding down either of the volume buttons alongside the side key and then slide to power off. Alternatively, you can also force restart your iPhone by pressing and quickly releasing the volume up and down buttons, one after the other, and then holding down the side key till the Apple logo appears.
Fix 3: Restart Your Router
There’s a good chance that the reason your iPhone 12 keeps disconnecting from WiFi is due to issues with your router itself. The easiest way to see if this is true is to check if other devices you own are also facing issues connecting to WiFi. If this is indeed the case, reboot your router and try connecting to WiFi on your iPhone 12 again.
Fix 4: Forget and Re-Connect to the WiFi Network
Sometimes authentication issues will prevent your phone from connecting to WiFi. If you have recently changed your router’s WiFi password, simply forget the network on your iPhone 12 and reconnect to it.
Fix 5: Turn on WiFi Assist
Newer iPhone models come with a WiFi Assist feature that strengthens your phone’s connection to your WiFi network. Usually, if your router has a weak signal, your iPhone drops the connection and switches to mobile data. Turning on WiFi Assist will prevent this from happening, and you will be connected to WiFi even with a weak signal. WiFi Assist is turned on by default on iPhone. If for some reason you had the option disabled previously, we recommend you turn it back on. To turn on the WiFi Assist option on your iPhone 12:
- Open the Settings app on your iPhone.
- Navigate to Cellular > Moble Data.
- Scroll down and tap the WiFi Assist toggle.
Fix 6: Update Your iPhone
As we have mentioned before, Apple does a fantastic job at pushing out the latest and greatest updates to its iPhones. Not only do these updates bring in new features, but they also squish a lot of bugs. If you’ve been facing the WiFi not connecting issue for a while, there’s a good chance that it has been reported enough for Apple to release a software patch.
We recommend you always stay up-to-date with the latest iOS version, not only to be free of bugs but also to have the best security features on your iPhone. To update to the latest version of iOS on your iPhone 12:
- Open the Settings app on your iPhone.
- Navigate to General > Software Update.
- Your iPhone will now check for any updates. If you have an update ready, tap on Download and Install.
Fix 7: Reset Network Settings
A good way to get rid of any network issues on your iPhone without having to completely reset it is to just reset its network settings. This will not affect any data on your iPhone, and will not tamper with any of the other settings. To reset network settings on your iPhone 12:
- Open the Settings app on your iPhone.
- Navigate to General > Reset.
- Tap on Reset Network Settings.
If you have followed all the troubleshooting steps on this list and have still not fixed the annoying WiFi connectivity issue on your iPhone 12, chances are that it’s a hardware-level problem that can only be fixed by Apple. If your iPhone is still under warranty, head to the nearest Apple Store and they should come up with a viable solution.
