WiFi Streaming Versus An Ethernet Cable Connection

Many routers are cheaply built and possibly a source of noise.  Wi-fi might help.  Search this forum for fiber media converters, and you will find several threads on inserting a fiber optic cable between your router and streamer (cost is < $100).  I did this on both of my systems.  It made a significant improvement on my smaller system which had been directly wired to the modem/router.  It made no noticeable difference in my main system, which was much further away and had several switches between the router and the streamer.  

When you finally give up on wifi and hook up a wired connection you'll be happy.

Agreed. Wi-Fi is to erratic. 

I am 98% fiber for our entire home. 

I use wireless streaming and find the closer you are to the router, the better.

My preference is to keep wireless emission to an absolute minimum in my listening space. Zero BT, WiFi even cellular while listening.
