Apple recently released the fifth beta of iOS 14.7, numbered 18G5063a, which doesn't seem to bring anything.
The bug was discovered a few weeks ago. As it turned out, when connected to a network with some strange names, the iPhone completely turned off the Wi-Fi module and refused to connect to other networks.
For example, Carl Schou told insocial networks that as a result of an attempt to connect his iPhone XS with iOS 14.4.2 on board to his home Wi-Fi network called% p% s% s% s% s% n the smartphone "broke". To reconnect, neither rebooting nor changing the network name helped - only resetting to factory settings.
Now if you are using iOS 14.7, when you connect to weirdly named Wi-Fi, your iPhone will work as expected. iOS 14.7 is already available to developers and public beta testers, but no public release date has yet been announced.</ p>
