WiFi not connecting after iOS 18 update

i had the same issue with my iphone 14 pro,I coudn't connect to wifi or even cellular network. I use Bitdefender VPN and as soon as i deleted the app all went back to normal.

Hey, I had the same issue after updating to iOS 18, and it was super frustrating. I have found many articles and videos and summarized the following methods. I hope they will be useful to you.

1. Forget the Wi-Fi network and reconnect. Just go to Settings > Wi-Fi, tap on your network, and hit Forget This Network. Then try reconnecting.

2. Reset network settings. This helped me—go to Settings > General > Reset > Reset Network Settings. It’ll wipe saved Wi-Fi passwords, so have those ready.

3. Disable Private Address. In Settings > Wi-Fi, tap your network, and turn off Private Address. That seemed to fix it for me.

4. Check for new updates. Sometimes they push out small fixes after a big update, so go to Settings > General > Software Update and see if there’s anything new.

5. Restart your router. Sounds simple, but it worked for me after trying everything else.

Try these and see if any of them help! If you want to know more details and methods, you can read this article, which includes all the above methods and introduces detailed steps.

Thank you I turned off the VPN and wifi was reestablished like a miracle. That was an easy solution for a big headache!

Had same problem on new tablet.

turn off IP blocking AND allow IP tracking in WiFi details… fixed the issue with ios18…. But does not sound like a good solution…, APPLE please fix

Love you for doing this. This resolved the issue for me. I should have know this was an issue because I could see how the toggle for VPN was going bananas and tunr off and on continuesly, I just deleted my SurfEasy VPN app and everything went back to normal.

Thanks for taking the time to check and get back with a solution

I deleted my VPN and I connected right away.

hope this helps

I found a fix for my TMobile ios 18 issue!

Under settings

VPN manage VPN

Option to Delete VPN

turn iPhone off

Turn iPhone on

Wifi works now after days without it!

Settings>General>Transfer or Reset Iphone>Reset>Reset Network Settings - This worked for me

Mine wouldn’t connect to the internet but worked when I mirrored to my TV. I left both Private and Limit IP selected but did remove the item from my VPN and now it is working properly.

Been talking to Apple Support about this problem. Even they don’t know how to fix this.

1. Tried to reset to factory settings
2. Reinstall iOS using Macbook
3. Changing WiFi settings

none worked.

We found out that WiFi connection works with 5gHz band routers, but not with 2.4gHz band routers. Most routers are still 2.4gHz.

I went today to an Apple Store to run a diagnostics, and I’m waiting for a feedback.

I will let you guys know if I succeed.

I had the same problem with my iPhone 14. Tried a bunch of stuff: reset network settings, turned off my VPN, restarted the phone, turned off private WiFi address and turned off limit IP tracking… nothing worked. I finally followed someone’s advice in this forum to restart the router. It fixed the problem. Turned on again private WiFi address and IP tracking and it is still working as it should. Hope this helps

I spent 3 days with Apple support and after the issue was escalated, Apple sent me a new 15 pro max with IOS 17.6.1 and my problems are over. I won’t be upgrading the IOS until it is stable !!

Turning off just “Private Wi-Fi Address” option worked for my situation, but I now receive constant privacy warning. Thanks!

Go to setting and search up network and then press reset network settings then reset your network settings.

After restarting the router, my WiFi problems seem to be over.

Strange, because in the mean time nothing had changed on it. Earlier in the week (before switching to iOS 18.1) my provider had been working on the network, but no other problems. Now after the restart I can restore my Private Wi-Fi Address and Limited IP Address Tracking and things are still working.

But find it strange that this reply doesn't automatically connect to my original post. Will copy this to the original post.
