Severe network issues (Wifi & Mobile Data) after updating to iOS 18.2.1

Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile. If that fixes it, you can try reinstalling VPN.

I have the same issue, and the issue can easily be reproduced. The issue affects usage seriously. Could you give me a hand?

Let me make clear it wasn’t the company google that did it. Google had flaws that were exploited by very intelligent people that had a lot of time on their hands.

I don’t know where it came from but check security certificates and see if there’s about 500 or so that don’t belong there and then hit me back.

That‘s still millions of dollars of tooling, which places your situation and your risks well outside of what can be addressed in a forum. You are reporting yourself as being a target of immensely well-funded adversaries.

The trusted certificate store is a fundamental part of modern network communications. The certificate store on Apple devices is protected similarly to the rest of the platform. Users can add certificates locally, but cannot add certificates to the trust store short of a separen security breach. And if there’s an existing breach that would allow it, there’s little reason to add some obvious and overt and easily-detected indication of compromise such as a new or changed certificate.

Again, you are reporting sophisticated exploits, well past the “reset and re-install” and “change your passwords” suggestions available around most forums, and what re-securing-related steps you’ve undoubtedly already tried.

That means collecting forensics, and mens working with folks that specialize in detecting exploits such as you’re reporting here. Also means reviewing your whole environment, expectations, and particular risks, and on what data you choose to maintain and where, and what data you purge. All of which gets into some personal details, ill-suited for discussions here.

I’m facing some issues since yesterday, seem Wi-Fi related but, although they’re random, they’re easy reproducible.

Siri is the worse. Sometime is fine, but when I’m on WiFi, it sometimes takes a long time to respond, or says that an error has occurred, as if the connection was lost, but my internet is fine with everything else. I don’t have this glitch when I’m on movile data.

Safari takes ages to load any page, mainly if I’m connected on WiFi 5g, or my other network.

I couldn’t update my iPad Pro 11in 4th gen due to an error with iTunes, so I had to restore it. Now it’s a pain to set it up and AppStore is gone, it has a black icon and says “Waiting”.

Am I the only one or iOS 18 has too many WiFi connection issues? I’m stressed out. Re-starting the router doesn’t help and nobody from Tech support helps

I would encourage you to post your own question in your own thread. These threads unfortunately end up being collections of unrelated issues, causing confusion for everybody involved.

What has Tech Support already had you do? You can choose to list that here (or in your new thread) or not, but you’ll probably get the same suggestions suggested again here.

Three common tests. Try each, and re-test:

1: Temporarily shut off iCloud+ Private Relay, if that is enabled, and test again.

2: Does the same problem happen with a completely different network?

3: Remove all of the add-on VPN apps, and all add-on security apps, and all browser extensions. Shutting off these apps variously won’t work. they need to be removed for this testing. Restart, and try again.

Please start your own thread, as this thread is (unfortunately) (unrelated) questions tangled together.

For your case in your new thread, please post details of what doesn’t and does not work, what you’ve tried, and what happened when you tried it. What equipment and versions are involved, too.

The current version I have with the issue is already the latest version 18.2.1. To which version should I update?

Mixed threads do get confusing, which is why I'd suggested starting a new thread with some details.

For your case, iOS 18.2.1 would be expected.

Please post details of what doesn’t and does not work, what you’ve tried, and what happened when you tried it. What iPhone or iPad too, and what networking equipment and versions are involved, too. Whether the problem arises with one Wi-Fi network, or with all Wi-Fi networks. And also if there are add-on VPN apps around. Or details of your local and network security as one part of this mixed thread references, if that’s the part of this mixed thread you are referring to here.

iPhone 15pro with iOS 18.2.1.

The problem occurs only when the device connects to the 4G network, and there is no issue with Wi-Fi networks. When the device connects to the 4G network, it randomly fails to access the network, and I'm certain that the quality of the 4G network is fine. After the device switches to a Wi-Fi network from 4G and then switches back to 4G again, the network can return to normal.

The device has installed a VPN app. However, the VPN is closed when the problem occurs.

No they weren’t, they were sending you scam texts, emails, or popups in browsers SAYING you had been hacked. It is a very common phishing technique that brings in billions of dollars a year for the perpetrators from people who actually believe the message contents→Recognize and avoid social engineering schemes including phishing messages, phony support calls, and other scams

I’ve found a back door thru google and android. I got hit with a sticky broadcast that came in on WiFi and Bluetooth taking over my system. You can’t stop it. It hit all five of my phones within minutes. I gave the evidence to the police but they didn’t know what to do

That’s at least several million dollars of exploit tooling and quite probably far more, and being targeted with that places your security risks and exposures far outside the sort of thing anybody can assist in a forum, or a vendor support channel, or local police.
