How to disconnect a Wifi connection instead of using "forget" connection

There is a simple way to achieve this.

we have two cases in our hands.

Case A: When The Wifi connection 'B' is already in the Remembered (Saved) List in your Device, then you have to just Open the Wifi -> Just Click on the Wifi Connection 'B' from the list. and it will automatically get connected to it.

Case B: When The Wifi connection 'B' isn't already in the Remembered(Saved) List in your Device, then Open the Wifi -> Just Click on the Wifi Connection 'B' from the list, and you will be asked for the password and then If the Signing process goes well. you are now connected to the Wifi connection 'B'.

Hope this helps you.

Izzy's note: Whenever you connect to WiFi B while a connection to A is active, the latter connection will be cancelled (disconnected) automatically as there only can be one WiFi connection active.
