Is 7 feet way from wifi access point (ceiling) to stereo risky for noise?

@dman777 I installed a Unifi gateway router with a UAP-HD-AC access point in the hall ceiling outside my listening room.  It worked very well until my audio ocd kicked in and I ran ethernet from the switch by the router to the room.  The Unifi system has worked very well in my house, though the access point is probably a little long in the tooth as far as IT progress has moved.  I have always run the Access point with POE from my Unifi switch that resides next to the Gateway router.  I also have another switch present on my rack.  I see no issues with the access point being 7 feet from your system.  

My streamer is about ten feet away from my router. I use ethernet to connect due to its proximity. I tend to use cables vs WIFI whenever possible due to my spread out mid-century ranch and the aluminum siding. Add AT&T's terrible native WIFI and signal loss. I have mesh units all over the house.

Buy a good linear power supply for router  like a LTA 

AND A good ethernet hub  lots of noise from these two points

a direct connection far better then wifi for music.

Use a mesh system or Wi-Fi extender along with a good Ethernet cable to create a wired connection, and turn off the wireless networking on your streamer. The sound is noticeably better and darker.

My mesh router extension was a little farther than that from my Bluesound Node, and I got a strong signal, so I doubt you will have a problem, but I guess it depends on what sources of noise are in your environment.  I live in a suburban part of a small town, so there may be fewer sources of noise, although a university is just a few blocks away.
