network setup fails completely on iPhone 6+

I try to set and access any one of several computers on my network with numerous folders shared with everyone and it completely fails to let me do anything at all… it cant find a single directory in any of my computers shared folders???? terrible user interface…. I have been banging around in the setting for 20 minutes and nothing in the networking will work like it should…. really bad design…. If I cant get it working before days end I am demanding my money back…..
