WiFi problem on new iPad Pro 4th gen My new iPad Pro (11-inch) (4th generation) purchased from Apple a few weeks ago (December 2022) keeps losing its WiFi connection. The connection will run fine all day but after I leave it charging overnight then the next day the WiFi often wont work. When this happens the settings still show it as connected to the WiFi access point but no apps can connect to the web and they all behave as if there is no network. An orange text message appears in settings stating "no internet connection" under the access point name. Does anyone else have this issue with a brand new iPad Pro? Anything I should try before going back to Apple? Trouble shooting steps: Toggling the WiFi off and on does not resolve it, neither did a network settings reset or "forgetting" the network and reconnecting. The problem just recurs randomly. Only thing that works is a restart (reboot) and then its back to normal until the next time. Speedtest shows performance is normal. Happens 2 or three times per week now. Nothing else has changed, its the same network setup I've been running for the past couple of years, all my other devices including iPhones and other iPads continue to have no issues. I think this is either a hardware or iPadOS software issue, but how to know? Apple support chat were not helpful, mostly wasting a lot of time asking about my network.

If Apple Diagnostics show an issue it will most likely need service.
