so the problem is when i put the SD INITIALIZATION PART,wifi stops 
and sorry once more,my code is all around the place at the moment until i make sure everything works fine,and my organizing skills are pretty low
can it be a memory problem? this code have as you can see all kinds of led blink stuff,but its just for debuging purposes at the moment,because device is outside,so i can see when i connect to it and when its sending data..later ill delete all of it
