Help WiFi advanced menu item missing on Samsung Galaxy S6

[magicbones]

I have just received new Galaxy S6 and have been trying to configure the WiFi settings but I've discovered that the Advanced option is missing. It should be found by going to Settings > Wifi > More > Advanced.
Has anybody else experienced this and, if so, have you discovered a way to get it back?

I am running Android 5.1.1

There is no individual setting called "advanced". After pressing "more" there are a number of options which are advanced options
