Wifi „no internet connection“ issues (iOS16)

Ever since upgrading to iOS16 my two phones have serious Wifi issues. It connects to my home Wifi but the connection is sluggish and unstable and the connection receives the label „no internet connection“. I have multiple other devices including two iPads, an iPhone on iOS15, a MacBook, all of which have no issues at all. This issue has also been reported last year after iOS15 rollout here. The issue does not occur on both phones simultaneously and pretty much at random. It first appeared on my older iPhone 12 and after receiving my iPhone 14 Pro Max, which has been setup using an iCloud Backup from the 12, the problem appeared there as well immediately.

Apple Support hasn‘t been much help yet. Reset network settings, delete all VPNs, restart router, set proxy to automatic, etc… all didn‘t help. This issue is also a pain to communicate. One Apple Support guy declared the problem solved as I could load a website (yay!). So my hope is someone from the community has silently found a solution for this.

I noticed this issue started recently myself. Resolution to these types of issues can be unique to your environment so please continue reading with that understanding.

It appears that the issue may stem from DNS resolution.

To quickly test this set your DNS to manual using the following DNS servers or similar (see image below).

8.8.4.4

8.8.8.8

These are Google's public DNS servers and safe to use. Your router by default will likely use your ISP's DNS servers which is generally fine but in this case we should rule them out. When you do this, if you see a DNS server with an address of something like 192.168.1.1, remove it (note after the third dot you may have a different number, for most installs it will look similar though). This is the default that is allocated from your router. If you leave this local address as your first DNS server address, you won't get a good test. In fact things could stay much the same so this step is important.

If this manual DNS change works you should consider changing your router's DNS settings to either the servers you used in the test or Cloudflare's or something.

It does; if it doesn't, contact your cellular provider.

That’s not normal for the update, but since it happened on yours you unfortunately need to deal with the consequences.

Hopefully it wasn’t too onerous.

It’s not the update or (seriously) millions of other users would be complaining about the issue, and… they are not.

Try restarting your WiFi access point/router.

Yes, but so does our iPad it's fine. And this issue is recent we've have the VPN for a while and it's only on when we travel.

Problem fixed. I use nord VPN which is a paid for subscription that I do trust. Thank you for the fix and info.

Do you have VPN installed on your phone, even if you are not using it?

Dec 8, 2022 7:08 AM in response to JasonAndTheArgonauts

Well, the most common cause is having a VPN app and profile installed. Do you?

iOS 16.2 no internet connection while obviously connected and getting data in some apps but not others. Weird.
