Note 4 bluetooth streaming issue

I'm uaing note 4 (snapdragon) android 5.0.1 with bose soundlink 3 for audio listening. At home I usually connect my phone with wifi (netgear jnr1010) and I use straming apps like gaana, saavn, wynk, hungama & youtube (first 4 are audio only similar to Spotify). But now and then I experience some stutters and skips. More frequently with youtube. However when I turn my ph wifi off then everything works smoothly. But then I'm on my precious mobile data. I have tried many forums and posts, tried many things but nothing seem to work. No one seem to have a real ans too. Please help
