Now Wi-Fi doesn't work for several Apple iPhone users following iOS 12.1.2 update
One Twitter user had a workaround for the loss of Wi-Fi connectivity. He says that disabling Wi-Fi calling and changing the settings from voice and data to data only might help. If your iPhone has lost Wi-Fi connectivity, it doesn't hurt to give this a try.

More bad new for some iPhone users who installed iOS 12.1.2
There is potentially some good or bad news on the way. Apple is beta testing iOS 12.1.3, but iPhone owners might be a little worried about what the next iOS update will do to their phone.
