I too am at my wits end with Roon- same scenario - for years it continually hangs up- suddenly drops out, requires a long slow reboot, endless issues. Yes, I've posted in the thousands of pages of Roon support - that should be the first warning sign btw- and get hundreds of suggestions and Roon's own tech support ineveitably wants two pages of technical details from me, ip addresses of everything on the network, rebooting protocols etc- and - it never solves the issue. All devices in my system are Roon certified - and still hang up.
I too just went completely hardwired from the router/modem directly to the Roon nucleus and my Lumin P1 is hardwired - and- I even now harwire my macbook to the ethernet- so- how is it and what is it that causes Roon to freeze, drop out and take 15 minutes of restarting, quitting, rebooting the nucleus and the lumin, only yo have it happen again randomly an hour later? It's the most frustating ongling issue- meanwhile the "back up" Blusound set up I have to maintain ALWAYS works, never, ver drops out or hangs up. And. It doesn't have an annual fee.
