I have a Onkyo TX-NR626, TP-LINK AC1750 Wireless Router, and a new Retina MacBook Pro. When I use NET\DNLA on the receiver to playback MP3s from my MacBook, a few songs will play and then the receiver will disconnect for a while. It will skip a few songs and they start playing again. No other devices are actively using the wi-fi, just a minimal of background work like email notifications.
It is very frustrating to be enjoying music then it stops in the middle of a song. It destroys the experience. I just moved to a new house and the router is new. The problem happened at my previous house with a different router. Why does the streaming get interrupted?
