Can't set Station only mode of esp8266 arduino

Question

When in WIFI_AP mode all goes well, but when in WIFI_STA mode it is still in WIFI_STA_AP mode.

How do I set the WiFi to station only with no software access point available.

  if(wmode == "AP") {
     Serial.println("Starting in AP mode");
     WiFi.mode(WIFI_AP);
     WiFi.softAP(ssid, pwd);
     WiFi.softAPConfig(charToIPAddress(ip), charToIPAddress(gateway), mask); 
  } else if (wmode == "STA") {
     Serial.println("Starting in STA mode");
     WiFi.mode(WIFI_STA);
     WiFi.begin(ssid, pwd);
     WiFi.config(charToIPAddress(ip), charToIPAddress(gateway), mask);
  }

EDIT: this is not about wmode, this code's if statement works fine, re: arduino String class operator (shorthand)

oh thats irrelevant... just an internal String classed variable, set to "AP" or "STA" only. — ChrisAdmin, May 02 '16 at 08:29
yea but unless you know the ESP8266 arduino code..... you won't know about the dual STA_AP operation of the device and how to turn it off. — ChrisAdmin, May 02 '16 at 08:32
Have you tried calling `WiFi.disconnect();` and `WiFi.softAPdisconnect(true);`? That's in the code I use to switch between AP and STA mode, and it works great every time. — Dawn Minion, May 02 '16 at 15:49
@Daniel Minion Worked great! Post a replay and i'll tick ya. — ChrisAdmin, May 07 '16 at 04:27
Glad to hear it worked for you - Summarised my theory into an answer. — Dawn Minion, May 09 '16 at 22:50

The ESP8266 seems to OR the mode parameter when you use WiFi.begin instead of just setting it, and also remembers what mode is it was in previously (Through reboots, for example). Calling WiFi.disconnect(); followed by WiFi.softAPdisconnect(true); should explicitly tell the ESP to disable all currently running WiFi operations - Be it infrastructure mode, or AP mode - And then you can define what mode it should be.
