Wi-Fi problem after iOS 14.7.1 update

Okay. What do you say to the phone intermittently connect to internet? It never loses connection to WiFi just internet. Nothing else in the house loses internet connection. As a suggestion from a previous comment, I turned Bluetooth off and the phone connected to internet. I will keep Bluetooth off and see if that actually makes a difference. I am at a loss. Not saying it’s the IOS update but it was working fine before??? So, if it is because my access point ( UniFi) and or my router (pfSense) no longer implement the standards used by IOS , then that would be new settings changed in IOS. Therefore, caused by IOS. Whatever it is, I hope it gets resolved quickly. I am going crazy 🤪

Yeah if you are looking but if you are not paying attention you don’t think about it. I am not one who lives on my phone so I can’t pinpoint when I started having the issues. Didn’t notice until after a storm and had to boot AP back up. Router never went down.

This is really making me crazy. My wife has an iPhone 8 on IOS 14.7.1. The same IOS as mine but my phone is an 11. Even as I type this, I just noticed my phone switched to WiFi. Her phone is fine. Only difference is she is on private address in network settings on iPhone. I’ll try that. Maybe something is just wrong with my phone. So, I doubt it is the IOS update but I don’t think it is my network either. If I figure it out, I’ll post the solution that worked for me.

Ok, will try this again since the mere mention of the latest os being tested is a no no.

So this issue developed on our iPhone 12 Pro MAX’s. Due to a game the wife plays, it gives a wifi needed message. Back phones are set up to also use cellular data when wifi is not connected. We also noticed that the cellular issue is also affecting zoom calls etc. In the settings I noticed the cellular settings was not showing my carrier. Valls and Texting was iffy too.

So I got out my 6s. It has iOS 14.2 on it. Pulled the SIM card from a 12 and put it in. At first the 6s did not see the sim. So I restarted the 6s with the sim in it and everything went fine. I manually turned off the wifi on the 6s and all is good too. Input the SIM card back into the 12 and bang, all good. Carrier shows in the cellular settings too. So I turned off the wifi and checked to see if the apps would pull down data via cellular. Yup. So I repeated this on the other 12. Same deal. A side note: both 12’s started having problems shortly after the 14.7 update. I went thru all the suggested fixes on the support page. Then I upgraded the iOS to (can’t say it) to see if that would help. Nope. Then I ran my SIM card test today. I will know more if it is a stable fix tomorrow but for now bango, it works like a phone again! And now I have 8 missed messages to tend.

I my opinion, the 14.7 is borking the sim cards either directly or thru something in the phones but I do believe it is the iOS and once it does it, it changes something related to the sim card that putting them into the old phone undid. This would also explain why a new sim would work for some and then fail.

Hope this helps. If it doesn't stay fixed I will repost. Sure hope they address this in 14.8.

I was having a similar issue with my iPad after installing 14.7.1. The Apple support people helped me to discover that an adblocker app I had downloaded created a vpn that is apparently incompatible with the new operating system. After deleting the vpn my WiFi issue went away immediately.

Just a follow up to my post: still working like a champ for me. From the posts, seems a tho there are multiple forms of the issue. The commonality is unfortunately the iOS. I dont know much about the iphone internal hardware or coding, but I will bet there is something common to all the hardware affected. And I am afraid that means waiting on Apple.

iPhones do not have the ability to write to SIM cards.

My wife and I are having this issue as well. It is absolutely not the router/ISP and clearly an iOS bug. Neither of us experienced this this issue prior to IOS 14.7.1. Once you toggle the WIFI, reboot, whatever it works again. However every time we return to the house and our phones re-connect to the WiFi, the issue shows up again. We have also not had any issues with any other device that utilizes the WiFi. Hopefully this will be resolved with ios15 official release.

I had the same issue, Apple replaced half my hardware only to have the issue again a month later. Now there is a new update but in order to update I need to be connected to wifi… which I cannot do…. Anyway around this?

Still having the issue with 14.8.

All three phones who have upgraded to 14.7.1 get this problem.

As others have mentioned, only started after iOS upgrade and all other devices work fine.

Using Xfinity xFi for wifi. Interesting note that internet works if connected to the wifi extender, just not if connected to the main router.

Hey everyone.. not sure if this helps but I had this issue and found that wifi settings on the iPhone automatically ses the “Private address” under wifi settings to on. So this creates a new MAC address and if you are using Mac filtering on your router (like I was) it will block connectivity. Turned this off and all started working as it was before 😊

Updated one device to iOS 15.0 just to see if it’s “fixed”. Nope. Still have to disable my VPN. Once disabled, the problem goes away. I’ve got a note into the developer of the app I use (1Blocker) to see what they know or have heard. Sigh…

Yes, I have the same problem with my iPhone 8 Plus after upgrading to iOS 14.7. And, there is nothing wrong with my Internet or Internet provider because my iPad and laptops are working fine — up 400 Mps.

The problem is definitely with the latest Apple iOS upgrade.

We had problems with both our iPhones until I uninstalled the VPN that operated via a security app called "Lookout". Once I did that , all was good. VPN is the problem. I didn't even realise that Lookout was using VPN when I bought it!

This issue is still not fixed in iOS 15.2, anyone else still having issues? I still have to disconnect from wifi and rejoin.

Did you mean 15.0.2? iOS 15.2 doesn't exist yet.

That having been said, I didn't have that issue before and still do not.
