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.

I literally just updated my iPhone to iOS 16.1.1 after that my entire phone settings has changed. I had to re-enter wifi password and fix my entire settings. Is this normal my fellow humans ? My entire settings has changed up after the update. I’m okay with that but what am I supposed to do now especially how the update changes everything ?!???!!

So my iphone 13 pro max was working perfectly fine today - then I updated it to iOS 16.1.2 and now my phone won't connect to the wifi.


As I have Alexa all over my home and I'm typing this on my laptop that is connected to my network -- and it was working just fine literally right before the update WTH is going on? I've read these comments trying to blame routers.. and its not the router.


This is a bug in the update. And a fairly serious one.

In what world do you live in that a bug has to affect all users? I’m sorry but that is asinine. Even if it is configuration specific, that is still a bug on Apple’s end that was not there before. It worked before, it doesn’t work now. The only change was Apple’s software.


I appreciate you trying to help people but blaming the user for what is clearly a software flaw is brand guarding.

I updated my wife’s phone and my phone and now have this same issue. All other devices still working on network but our two phones will not stay connected to ANY Wi-Fi (not just ours). I’ve tried all the usual remedies to no avail.

This is absolutely and undeniably a bug with the update. Bugs happen - they just need to be fixed and they don’t get fixed until folks accept it’s not a end-user problem.

Are you using VPN? If so, did you delete the VPN and reinstall it after updating?



And it IS deniable that it is a bug. A bug doesn’t affect dozens of users, it affects thousands.

I’m having the issue as well. Had it with one provider-Verizon. So switched to AT&T and just updated my phone and having it again. Got Tmobile home internet router less than a month ago. Connecting is fine but no internet connection on phone wifi shows. They have replaced the router and still doing it. Have Century link home internet as well. Does it with that as well. They checked All the lines and updated my router twice. Still happening. Tried resetting the network settings, still happens. I’m really over it. Lots of people are having this issue honestly. Mines been working fine for 2 years and all of a sudden 3/4 months ago it all turns to ****

Also have this issue on IPhone 13 pro Max, same exact issue. Nothing resolves it. It's IOS 16 itself causing the problem as far as I can tell. I have done everything you can think of, (reset network settings, I don't use VPNS, reset router, modem, etc.). Only thing I have not tried is restoring phone from backup. I won't be doing that. I have just disabled WIFI for now as it's unreliable.

Also, 16.0.2 did NOT fix this issue.
