To avoid the wifi issue. Get a cheap wall wart wifi extender and plug next to Aurrender. Connect extender to Aurender via Ethernet. Works wonderfully and sounds great with high quality streamers like the Aurender. Both my systems work that way, I know of a number of $100K+ systems working like this.
Solving this problem was what originally drew me to buy an Aurlic Aries G2. The wifi extender solved the problem allowing me to use Aurender streamers and improve audio performance. My streamer performance is at the level of my analog system.
