My Xperia Z1 Compact keeps losing its connection to Wifi networks, and once it does I cannot reconnect to any Wifi network without once turning off and turning on again the Wifi (on the phone).
Even when lose its connection, it will show the Wifi access points with full signal strengths in the available AP list, but tapping the connection button will not do anything. No error message will appear, but it will not connect either.
None of the settings related to Wifi (wifi connection during sleep, wifi optimization, stamina mode, etc), regardless of its combination seem to make a difference. The same go for the Wifi setting on the AP, nor the model of the AP seem to make a difference (and I've tried with at least a dozen AP, but public and private with various security settings).
The only way to reconnect is to first turn off the Wifi and then turn on again, which is simply frustrating given how often it happens for such a basic functionality.
