Show current SSID under WiFi indicator in Notification panel
I think android version is not the same anymore as on the question but on 7.0 (Nougat) if you pull down the status bar using 1 finger you don't see the wifi SSID (1st picture) and if you use 2 fingers you can see more icons and details (2nd picture), including the SSID. See pictures (on the same fone). (obs: pulling with 1 finger and pulling a 2nd time is the same as pulling with 2 fingers)
