Why does wifi stop working after 12.3.1 update?
We have had about 15 ipad mini 4s completely lose wifi functionality after being updated to the newest OS. In every single case, wifi functioned normally until after the update. some of them were updating from 11.x to 12.3 or 12.3.1, some were going from 12.2 to 12.3 or 12.3.1. The switch in settings for wifi is greyed out and cannot be flipped, and no wifi signals are detected during setup stages (there are routinely 4-6 access points or signals found on any given device in our building). It is absolutely without a doubt NOT a problem with our wifi, as it only happens in these devices, and only after they are updated to 12.3 and above.
Has anyone else seen this or have a solution other then the obvious “reset network settings” or “erase all settings” or restoring. This has not remedied the issue, and all antennas are properly connected.

well so far no progress. but we do have 3 more devices- all mini 4s- doing the same thing. no wifi after being updated to 12.3.1. for a total of 18 no wifi mini 4s. Apple this is a problem, but im sure you’ll never admit or address it.

@chriskennedy44 replacing WiFi module didn't solve this issue?
@sammyz replacing antennas did not. not able to replace wifi module at this facility, as currently no micro soldering. wifi was verified to work before updating the OS, so really doesn't make a lot of sense for it to be an actual hardware problem across so many devices

I thought I was the only person this was happening to. Took my mini 4 to apple and the tested it and everything and nothing failed hardware wise. They told me I could t be the software and I could exchange it for $299. I’m so frustrated

I have an Iphone 7 that had the same issue after updating to 12.3.1, I was told that the wifi module died at the same time as a 'coincidence'. Interesting to read this now. I still have the device, although it is basically a glorified camera now, as I did not want to pay to have the wifi module replaced on a 3 year old phone. I may need to look back into this. Thanks
