If you’re an iPhone 12 user facing these challenges, you’re not alone. In this article, we will explore common reasons why your WiFi and Bluetooth may not be functioning, as well as provide solutions to get you back online.
Understanding the Importance of WiFi and Bluetooth on the iPhone 12
The iPhone 12 is designed to be your all-in-one device, offering seamless connectivity through WiFi and Bluetooth technologies. WiFi allows for high-speed internet access, while Bluetooth enables connections with a range of devices like headphones, speakers, and smart home gadgets. Without these functionalities, the capabilities of your iPhone 12 are significantly diminished.
Common Reasons for WiFi and Bluetooth Issues
Before diving into the solutions, it’s crucial to understand the potential causes behind your iPhone 12’s connectivity issues. These can range from simple software glitches to hardware malfunctions.
1. Software Glitches
Software issues often arise after updates or due to bugs in the system. Here are some common software-related problems that can affect WiFi and Bluetooth on your iPhone 12:
Unstable iOS Version
Occasionally, a new update can create instability in existing features, including WiFi and Bluetooth.

Though less common, hardware-related problems can also lead to connectivity issues on your iPhone 12.
Physical Damage
If your device has experienced a drop or liquid exposure, it could adversely affect the internal components responsible for WiFi and Bluetooth functions.
Faulty Antenna
The antennas responsible for your WiFi or Bluetooth signals can occasionally malfunction or become disconnected.
3. Network Issues
Your home network or the device you are trying to connect to could be the culprit. Problems with your router or the Bluetooth-enabled device may hinder connectivity.
4. Settings Configuration
Improper configuration of settings can lead to issues as well. You might accidentally disable WiFi or Bluetooth, or your iPhone could be set to “Airplane Mode”.
Troubleshooting Your iPhone 12 Connectivity Issues
When facing issues with WiFi or Bluetooth on your iPhone 12, it’s critical to follow a systematic approach to troubleshoot.

What should I do first if my WiFi and Bluetooth are not working on my iPhone 12?
If your WiFi and Bluetooth aren’t functioning on your iPhone 12, the first step is to restart your device. This simple action can often resolve temporary glitches that may be affecting your connectivity. To restart your iPhone 12, press and hold the side button along with the volume up or down button until you see the power-off slider. Slide it to turn off your device, wait a few seconds, and then turn it back on.
After restarting, check if your WiFi and Bluetooth are working. Go to “Settings” and tap on “Wi-Fi” to see if the networks are showing up. Then, do the same for Bluetooth. If you can now see available networks or devices, your issue may have been a temporary glitch resolved by the restart.
Why is my iPhone 12 not connecting to WiFi networks?
If your iPhone 12 isn’t connecting to WiFi networks, start by ensuring that the device is not in Airplane mode. You can check this by swiping down from the upper-right corner of the screen to access the Control Center. Make sure that the airplane icon is not activated. If it is, tap it to disable Airplane mode and retry connecting to WiFi.
In addition, check if you’re within range of the WiFi network you want to connect to. If the WiFi signal is weak or intermittent, your device may struggle to establish a connection. Consider moving closer to the router or restarting the router itself, as sometimes the router may also be the issue causing connectivity problems.
What should I do if the WiFi icon on my iPhone 12 is greyed out?
A greyed-out WiFi icon can indicate that there is a hardware issue or that the WiFi settings have been disabled. Begin by going to “Settings” and selecting “Wi-Fi.” If you see that WiFi is turned off, toggle it on. If the option remains unresponsive, it may indicate a deeper software or hardware problem.
If toggling doesn’t work, try resetting your network settings. Go to “Settings,” tap “General,” then “Reset,” and choose “Reset Network Settings.” Keep in mind that this action will erase all your WiFi passwords, so make sure you have them handy to reconnect afterward.
Can software updates fix WiFi and Bluetooth issues on my iPhone 12?
Yes, software updates can resolve bugs and issues related to WiFi and Bluetooth on your iPhone 12. Apple regularly releases updates to improve performance and security, and these updates can sometimes address specific connectivity problems. To check for any available updates, go to “Settings,” tap “General,” and select “Software Update.” If an update is available, download and install it.
Once your device is updated, it’s a good idea to reconnect to your WiFi network and Bluetooth devices to see if the issue has been resolved. If problems persist, you may need to look for additional solutions, but ensuring that your software is up-to-date is a crucial step.
What if I forgot the WiFi password on my iPhone 12?
Forgetting a WiFi password on your iPhone 12 can be frustrating but there are a few ways to retrieve or reset it. If your home network is managed by a router, you might find the default password on the router itself, often printed on a label on the unit. If you have changed the password at any point, you might need to reset the router to the default settings.
Another option is to use the Keychain feature if you have a Mac; your WiFi password may be saved in your iCloud Keychain. Open the “Keychain Access” app on your Mac and look for the name of your WiFi network. You can then reveal the password by checking the box next to “Show password” while entering your Mac’s administrator username and password.
Why is Bluetooth not working on my iPhone 12 even after restarting?
If Bluetooth is still not functioning after a restart, the first step you may want to take is to ensure that your Bluetooth accessory is also powered on and within range. Many issues arise from the device or accessory not being turned on or functioning properly. If necessary, consult the accessory’s user manual for connection instructions and troubleshooting tips.
If both your iPhone and the accessory are operational, consider forgetting the device in Bluetooth settings. Go to “Settings,” tap “Bluetooth,” find the device in the list, and select “Forget This Device.” After that, try reconnecting by searching for the accessory again. This may resolve any pairing or connection issues.
What does it mean if my iPhone 12 can’t find Bluetooth devices?
If your iPhone 12 cannot find Bluetooth devices, it might be due to various reasons including the Bluetooth accessory being out of range or turned off. Ensure that the device you are trying to pair is on, in pairing mode, and close to your iPhone. Many devices require you to press a specific button or hold down a combination to activate their pairing mode, so refer to the accessory’s instructions.
If the accessory is powered on and still not appearing, try resetting the Bluetooth connection on your iPhone. Go to “Settings,” select “Bluetooth,” and toggle it off and back on. This may refresh the Bluetooth functionality and allow your iPhone to detect nearby devices.
Will a factory reset solve my WiFi and Bluetooth issues?
A factory reset can potentially fix persistent WiFi and Bluetooth issues on your iPhone 12 if all other troubleshooting steps have failed. However, it’s important to note that a factory reset erases all data from your device, so it should be considered as a last resort. Before proceeding, ensure that you backup your important data using iCloud or by connecting your iPhone to a computer.
To perform a factory reset, go to “Settings,” tap “General,” scroll down to “Transfer or Reset iPhone,” and choose “Erase All Content and Settings.” After the reset, you will need to set up your device as new or restore your data from a backup. If WiFi and Bluetooth issues persist even after a factory reset, consider contacting Apple Support to explore hardware problems.
