So, I started experiencing issues with both Wi-Fi and cellular data on my iPhone XR running on iOS 16.3.1 yesterday. With cellular data, I could see the 'LTE' symbol, but I couldn't browse the internet. Similarly, with Wi-Fi, the signal would show for a second after connecting, but then it would disappear. I decided to update to the latest iOS version and restore from backup, but the problem persisted even after the update. Then, I wiped the phone again and set it up as a new device. This time, the Wi-Fi/LTE was working without any issues. However, when I tried to restore from backup again, the problem returned. I had to start from scratch once more. What a pain in the ass that was... Has anyone else gone through something similar?
I have been using this phone for a while now, and this is the first time I've encountered a major issue like this.
