I can confirm that the second 14.5 beta does NOT fix the WiFi dropping issue. So utterly disappointed.
Lots of different issues in this thread. The specific issue I’m having is the WiFi dropping issue. Our iPhones and iPads will disconnect from WiFi if left idle. As a result personalized HomePod requests don’t work, iPads receive no new data for notifications (think iMessage, emails, etc), and iPhones resort to 100% cellular data. When the device is picked up and unlocked it doesn’t connect back to WiFi on its own and so you have to manually go into settings and tap on the network. Of course my kids don’t do this on their iPhones so they continue to use cellular data even though there is strong WiFi available in the house. As a family our cellular data usage has doubled.
I’ve tried every “fix” and workaround in this thread and nothing works. Even retired my AirPort Extreme routers and bought a new eero pro 6 mesh setup and still the same thing.
None of my non-Apple devices have this issue.
