How to Fix Wi-Fi Issues on iPhone 12 Pro running iOS 14 – iOS 14.5

Here are some time-tested solutions to fix the Wi-Fi issues on your iPhone 12 Pro after upgrading to iOS 14 – iOS 14.5.

1. Restart Router

Before we look at troubleshooting wi-Fi issue on your iPhone 12 Pro running iOS 14 – iOS 14.5, let us do some basic troubleshooting at the router level. It has helped resolve the issue for several readers.

If you find your iPhone 12 Pro dropping wi-Fi, restart your router and try connecting your device again to see if it resolves the issue.

The router is like a mini-computer with a CPU, memory, and local storage in the plastic box, running in an operating system. So like a computer, restarting your router can fix iPhone 12 Pro Wi-Fi problem. It is also recommended to wait for 10 seconds after you have turned off your router before restarting it to Ensure that every capacitor is fully drained, and thus every bit of memory is cleared. This ensures that all the settings on the router that may be causing the issue are reset.

2. Update Router Firmware

Update your router’s firmware to ensure that the known bugs have been fixed. This should be done regularly as firmware updates for your Wi-Fi router can improve its performance or fix bugs and security issues.

3. Auto Connect Problem

If you have connected your iPhone 12 Pro to a Wi-Fi network, then it should ideally connect to that network automatically when you are in its range. Suppose your iPhone 12 Pro is not automatically connecting to the WiFi network, and you need to connect to it manually. In that case, you might want to check if the Auto-Join setting is enabled by launching the Settings app and navigating to Wi-Fi > and check if Auto-Join toggle is enabled. If it is already enabled, then you can try the solutions mentioned below.

4. Hard Reset or Force Restart

Like all tech problems, there is no harm in starting off by force restarting or hard resetting your phone to see if it helps fix iPhone 12 Pro losing wi-Fi issue.

Press and quickly let go the Volume Up button. Press and quickly let go the Volume Down button. Then press and hold the Side button until the Apple logo appears.

5. Disable VPN

One of the most common reasons that seem to cause iPhone 12 Pro WiFi issues is VPN. If you have enabled it via the Settings app or a VPN app, then try to disable VPN to see if it resolves the issue. You can disable VPN via the Settings app and navigate to the VPN settings to disable the Status toggle from Connected to Not Connected. If you are not able to disable it, then launch the VPN app to disable VPN temporarily to figure out if it resolves the WiFi problem on your iPhone 12 Pro.

6. Forget Wi-Fi Network and Rejoin

If you’re not able to connect to a Wi-Fi Network and being prompted that the password you’ve entered is incorrect despite entering the correct password, then try to forget the Wi-Fi network and join the network again.

To forget the Wi-Fi network, tap on the Wi-Fi network from the list under Settings > Wi-Fi. Then tap on Forget This Network. You will be prompted with a popup message asking you if you want to forget Wi-Fi Network. Tap Forget to forget the network.

Now go back to Settings > Wi-Fi, select the network again, enter the password, and join the network again to see if it helps.

7. Reset Network Settings

Most iPhone 12 pro connection issues I’ve experienced have been fixed after resetting network settings. Resetting these settings flushes caches and clears DHCP settings and other networking-related info. To reset network settings, open the Settings app and navigate to Settings > General > Reset and tap on Reset Network Settings.

8. Disable Wi-Fi Networking Services

Many users generally tend to solve iPhone 12 Pro Wi-Fi issues by disabling Wi-Fi Networking under Settings > Privacy > Location Services > System Services. This only relates to your location being used for Wi-Fi Networking, so it doesn’t disable Wi-Fi entirely.

9. Set Custom DNS

If you find your WiFi connection is slow on your iPhone 12 Pro, then it is possible that your ISPs DNS servers are having problems. You can switch to Google DNS, Cloudflare, or OpenDNS to see if it fixes the problem.

10. Ask To Join Network

This is not an ideal solution, but if none of the solutions mentioned above fixed iPhone 12 Pro internet issues, then you can try enabling “Ask to Join Networks” by going to Settings > Wi-Fi. If it works, you can try disabling it again after a few days or weeks to see if the problem crops up again or not.

11. Wi-Fi Assist

iOS includes a feature called Wi-Fi Assist, which provides more reliable Internet connections when your WiFi network becomes spotty. However, this can cause iPhone 12 Pro internet connection issues, particularly if your ISP has patchy connectivity. So, it is best that you turn off Wi-Fi Assist by going to the Settings app and navigating to Cellular (Mobile in some regions). From there, scroll down to the bottom, where you will see Wi-Fi Assist. Tap on the toggle to turn it off.

  1. still does not work! very upsetting. It is an expensive phone and doesn’t even work with its own products. Trying to put my apple watch on and cant even do that.

    • The issue seems to be caused by the personal hotspot. I find that once I turn off the personal hotspot the wifi will automatically connect.

    • We have 4 iPhones and one Samsung , and all iPhones have this issue. This has deterred out family from Apple tbh. Device used to complain about security WPA2, now it don’t do even connect. My router does not have the option for WPA3. Why should apple dictate when I need to change my router? I am almost done with Apple products.

  2. My iPhone 12 reset by itself and won’t let me turn my WiFi back on even though I tried all of those things more than once
