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 😊

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 🤪

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.

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.

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.


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