New wireless hub/router

I use an Eero mesh network. I have one of the Eero units in my music room, I plug my Innuos directly into the Eero unit. No problems

Not really clear what you mean when you say wireless hub? Is it a mesh system like mine below?

I have Xfinity tower with modem and router built in connected by hardwire to the street box. I have a second Linkys mesh system hardwired to the Xfinity tower with nodes connected wireless throughout the house. My Roon core is a sonic transporter connected by hardwire to my mesh tower. One Linkys node (in a different room) is next to my main system hardwired to my network streamer. Additionally, each router can provide a separate network (2) so i have my second Home Theatre system on the Xfinity tower and my 2 channel system on the linkys mesh router. It has worked flawlessly as long as xfinity doesn’t go down. Very happy!

The new router should have at least four Ethernet ports on it in addition to adding WiFi capability. So provided the new router is located in the same location, no change, you will just now have WiFi all over the house.

In general, high quality streamers isolate you from the network and therefore can work optimally from an extender, but if you are close, definitely direct wire your streamer.
