When seeking answers, I found the problem that iOS 14 no connection to Wi-Fi, and no cellular data is common for some iOS 14 users. And many solutions were provided by many people who have experienced it. To troubleshoot the problem with the least effort, time money and data sacrifice. I suggest you resolve it following the below steps.

The scenario on My iPhone iOS 14 won’t connect to Wi-Fi and cellular data:

As the snapshot shows, when I check the Settings > WLAN > My internet name, Tap it. I saw the iPhone shows me Weak Security.

WPA/WPA2(TKIP) is not considered secure. If this is your WLAN network, configure the router to use WPA2(AES) or WPA3 security type.

Having checked my router with no WPA2(AES) or WPA3 security type option, I abandoned the method to change my router which used to work well, the last thing I want to do is to buy a new router.

Having tried many suggestions online and ask experts in person, I conclude the following steps.

Wi-Fi No connection and no cellular data Issues in iOS 14 on Your iPhone Troubleshooting steps.

After each step, check if the problem is resolved.

  1. Forgot Wi-Fi Network and Rejoin.

If there is no Wi-Fi connection on your iPhone, try to reconnect your network.

Tap Settings > WLAN > Tap your Network Name, Tap Forgot this Network. Later, on the WLAN Page, tap your Network name and enter the correct password to join it.

  1. Make sure your internet connection (including Wi-Fi) is active.

To test whether your internet connection is active, disconnect from any VPN or internet proxy on your iPhone and see if you can access the website. If you are able to access the internet while disconnected from any VPN service or proxy move on to the next step.

  1. Restart your Router.

Restart your router and reconnect your iPhone to check if the problem is resolved. Wait for a few minutes after you have turned off your router. Later, turn it on again. This ensures a full restart of your router and settings that may cause this issue.

  1. Turn off the Private Address on your iPhone.

To improve privacy, iOS 14 and iPadOS 14 use a different MAC address for each Wi-Fi network. You can turn it off to see if the iPhone can connect to your Wi-Fi.

Go to Settings > WLAN > Your Network Name. Tap it and on the Network Page, toggle the Private Address Option to off. You need to rejoin the network to stop using the private address.

After resetting the network, you should go to rejoin the Network and see if it works.

Some people can only resolve the problem by restarting their iPhones. It is worth a shot for one or two minutes.

A force restart does no harm to your iPhone to troubleshoot any problem.

  1. Disable VPN on your iPhone.

VPN is one of the most common reasons to cause no Wi-Fi connection issues. That’s because VPNs have changed the network settings and use their own network servers base on the local network.

You can uninstall your VPN app from your iPhone completely. Or you can Disable the VPN services from the Settings app.

Go to Settings > VPN, toggle the switch to off beside the status option of your VPNs one by one.

  1. Reset All Settings.

You are prompted to enter your passcode to reset all settings.

Go to Settings > General > Reset > Reset All Settings.

Some people can reconnect to Wi-Fi and cellular data after doing this.
