Inspiron 15Z network (wifi) card replacement

​I was disappointed to find out my wifi card in my 15Z was not dual band. I am thinking about replacing it so I can use tehe 5ghz band. I am thinking about replacing it with a ​​Intel® Centrino® Advanced-N 6235​​. Does anyone know if this is swappable with the ​​Intel® Centrino® Wireless-N 2230​​ that is already installed? Anyone know how difficult it is to swap out?​

​ ​

​Thanks​
