Auto Reconnect to a Wi-Fi Network auf Realme
Realme UI keeps a list of saved Wi-Fi networks and reconnects to them automatically once your phone is back in range. This behavior is controlled by a per-network switch called Automatically reconnect, not by a single global toggle.
That is why one saved network can silently rejoin while another asks for the password every time. If the switch is off for a network, your phone drops that connection when you leave range and will not rejoin on its own later.
To check or change it, go to Tap on Settings ➔ Tap on Wi-Fi, select the network from the saved list, then Open the Menu ➔ Enable or disable Automatically reconnect.
Turning this off makes sense for networks you only use occasionally, such as a hotel or an office guest network, so your phone does not try to rejoin them by default. Turning it on is useful for your home or work network so you do not have to reconnect manually every time you walk back in range.
Disabling auto-reconnect does not remove the saved password or forget the network. It only stops the automatic join, so you can still select the network manually and connect with the stored credentials whenever you want.
