Connectivity via my at home wifi is spotty

I have great wifi throughout me house but it seems that when I try and stream video or music I get about a 50% success rate. For me it either works 95% of the time or it is a nuance and I wont use it. I bought it to stream my music library to my smart devices but now it is just a hard drive.
