What @soix stated is a reasonable approach, I do think you need some isolation and I will tell you why. I recently moved to a new room away from my router, and as a quick solution while I debated running cables, I bought a TP-Link extender with an Ethernet port and used that. One day I decided to see how a hardwired link would sound and I ran my 30’ Blue Jeans CAT 6 cable across the floor between rooms. This had significant negative effects on sound, I was quite surprised. You might try the extender approach before you start running wire.
