OMV on RPI3 can't figure out the WIFI

Hey guys, first off let me say I set myself up a nice little nas with a Rpi and a 2TB Slim HD. I'm getting some acceptable speeds as the largest files I transfer over are around 1 gig or so. I'm struggling a little trying to setup the wifi. It is possible to do on an RPI3? Is there a guide somewhere that will help me with what kind of info to put in the fields? I've been a windows user and have always been able to set up wifi with a mouse click and a p/w, working within linux now so much. Thanks,

still trying to figure this one out. when I enter my wifi details in the GUI I loose all internet connection including the ethernet. any ideas?
