A couple of years ago I went to an ASUS Mesh network for our home. The base router, an RT-AX86U sits upstairs in my den next to the Motorola cable modem. Downstairs are two RP-AC1900 Mesh nodes that are networked over the air to the main router upstairs.
One node is in my wife's office downstairs that serves her wifi needs with enough range to serve our outdoor patio shelter as well. (I move my wifi pellet grill under it for our PNWet winters ) It also serves our smart TV in the den.
The other node I tried to install in the same cabinet in the living room as my hi-fi rig but it generates so much RF (Hello? Wifi!) that it made my CJ Premier 6 impossible to use. So I moved it into a bookcase across the living room and ran some quality Cat 8 from it to my streamer. Problem solved.
Here's a review of the Plume system:

I gotta tell you, I'm not impressed on either a cost or performance basis. But getting back to your question, sorry I veered off course there, if you can I would move any RF generating gear away from your hi-fi rig. It doesn't have to be that far really. Then I'd run good quality Cat cable from your router back to your streaming device.
Good luck and as always...
Happy listening.
