Wifi „no internet connection“ issues (iOS16)

Does your celluar data work when you have these wifi issues??? When this happens to me I try turning off wifi and it vonnects to the 5g and I still have no internet connection with any of my apps. It’s odd as my other ipad and iphones not running ios 16 doesnt have this issue. I only started noticing this after 16.0.1. The only way I was able to resolve it for a few weeks is just restarting my phone.

I am having this same issue after I upgraded to iOS 16. My iPhone 11 Pro Max is doing this exact same thing, but my iPhone 8+ and iPads are not. They are all on iOS 16. The iPads dont leave the wifi range and Im afraid to take them anywhere as they may start acting up. But I have been troubleshooting with Applecare and they replaced my iPhone 11 with a new one and then it did the same thing. I just received a second new one and it is doing the same thing too. I am still waiting to see what Applecare is going to do as we have trouble shooted the heck out of these phones. I have also called my wifi and internet provider and they have performed a bunch of tests and dont seem to find any issues. (It was all working fine until iOS 16) Anyway, I am glad I found this discussion, as at least I know it is not just me with this issue, and it has given me great things to look for and test on my own to try and get this fixed. I wish I could go back in time when the phone actually did what it was supposed to do. Thanks for all this info!

This is my first iPhone and may very well be my last.

Basic troubleshooting (test after each step):

• Restart your router by turning it off for about 15 seconds (even if other devices are working)
• Restart the phone→RESTART your iPhone, iPad, or iPod touch - Apple Support (you won’t lose any data)
• Settings/General/Transfer or Reset Phone/Reset/Reset Network Settings (you will have to re-enter Wi-Fi passwords, but won’t lose any data)
• Investigate→Resolve Wi-Fi and Bluetooth issues caused by wireless interference - Apple Support

It is your router.

Something about your router doesn't like the way iOS 16 is sending traffic and it is failing.

If you have a good router, nothing iOS 16 does should bother it, and that's indeed the case for many routers.

Telling people to shut off "limit address tracking" - despite the security implications thereof - is not a valid solution, though arguably it may help on some routers that are in need of firmware updates.

That's a pretty extreme action. Maybe consider just resetting all network settings? I can live with this. It's been tolerable since I rolled back my firmware in my router, which I think may have contributed. Still, frustrating considering these are "consumer" products. Never had to do things like this with a car or a stereo. Pretty demanding to keep these things working. Do better Apple!

I agree, I have been dealing with this since September. I have tried everything that I can find and that AppleCare has done with me and none of it worked. They have told me that this is a known issue and have escalated it to engineering. I have spent way too much time on this, it should just work. It’s frustrating and disappointing. So I finally tried reset all settings instead of setting back to factory, been there, didn’t work, and not going back. So far, this is the only thing that has made some difference. Frustrating anyone should be in this situation.

If neither Wi-Fi nor cellular data works your phone is broken. Use the Support link at the top of this page to arrange for a repair.

I did do a factory reset on router, did not solve the problem. It is a newer (couple years) EA8300 linksys. ATM I just have wifi turned off on my phone because the slowness was annoying me. I do see other people complaining about it on various forums and twitter, but not a ton, as you mentioned in another comment. Have not tried any VPN stuff, as I normally do not use one, but I might try that later tonight. Thanks.

Hi Lawrence,

Thanks for the steps in detail.

Here are my findings when the internet again went down

•DHCP lease time is 24 hours.

•IP address before and after the internet went down was still same starting from 192.168.x.x.

• All three devices that were connected to router were assigned different IP adressess so none of them were colliding with my device IP address.

• DNS is configured to automatic. Changed it to manual and typed google DNS but still same “No internet Connection” issue.

• I dont use iCloud+ therefore private relay option isn’t available in iCloud settings.

• I didnt use VPN at the time this issue occured, but one profile was there. Deleted that profile but again issue didnt resolved.

• Had to restart iphone again to get this fixed again.

• Will connect with wifi hotspot device for a day and see if same behaviour occurs there.

Hi DogCow,

I have followed the steps suggested by Lawrence and provide my inputs.

Thanks for explaining above how this works.

I have one question, that if we assume that DHCP server was botching the renewal requests, then shouldn’t it botch the requests for other devices as well. Why is it doing this only for 1 device and how do we fix this?

What are the other devices? If they are always connected they don’t send DHCP requests. It’s only devices that are out of range of the network periodically that request IP addresses when they reconnect.

Im having the same issue and I did try to connect to several different wifi networks, and it did the same thing (connects to wifi, no internet connection) on a few networks and on one network it worked for a little bit then the no internet connection message popped up. Its very frustrating.

I have noticed that my phone is slow intermittently. It’s not the Wi-Fi because all of my other devices do not have the issue. I have a brand new iPhone 14 Pro and have contacted apple support.

This is my first iPhone and may very well be my last.
