My Wi-Fi connection often drops out.
When that happens, the Wi-Fi switch automatically turns “off.” And it says that no Wi-Fi networks are available. (This message is incorrect.)
It’s not enough to just turn the Wi-Fi switch “on” again. Wi-Fi reception doesn’t come back until the phone has been turned off and then back on again.
