WiFi not connecting after iOS 18 update

I updated my iPhone 16 to iOS 18 on the 26th sep. After the update, my phone won’t connect to wifi. It shows “no internet connection”under the wifi name. I have tried every solution stated online but to no avail. Any suggestions pls?

It’s not a wifi/ router problem cuz my iPad (with iPadOS 17) & other devices are working fine. It’s really frustrating because idk how long I can go like this with my phone not being able to connect to any wifi….I also don’t know when the next update is gonna launch & whether it will fix this wifi issue or not

iPhone 14, iOS 18

As promised, I’m back to report on my visit to the Apple Store regarding the WiFi issues I’ve been experiencing since the iOS 18 update.

The staff at the store pinpointed the issue to incompatible certificates and VPN profiles that were blocking WiFi traffic.

A NordVPN certificate was causing interference, even when the VPN was not active.

Their recommendation was to delete the problematic certificate, reinstall NordVPN, and adjust settings to trust all WiFi networks.

After following these steps, my WiFi connection was instantly restored.

For those who are facing similar connectivity problems, checking for outdated certificates or conflicting VPN profiles could be the key to solving your issue.
