iPhone 16 Wi-Fi and Bluetooth intermittently turn off after iOS 27 update

About a month ago, I upgraded my iPhone 16 from iOS 26 to 27. I am currently on 27.0.1.

Since then my phone will turn off WiFi and Bluetooth once every other week. The other thing I can do to get it working again is to restart the phone.

The first time it happened I was on my home wireless and had just woken up. Everything was fine for a few minutes then it went down.

The next time it happened I was driving to work and had Bluetooth connected to my car’s radio. A few minutes after I got to work it went down while staying on a 5G connection.

I’ve reset my network settings and turned off WiFi assist but it has happened again since.

That iOS version is no longer current.

Thank you. I had checked prior to posting and there wasn’t an update then but there is now. I’ve updated so we’ll see if this fixes it.
