Yes, it should work.
But testing with cables is meaningful.
Just get some long Ethernet cables and lay them over the living room floor, up or down stairs, whatever you need to do. This is just a temporary test. Doesn’t matter if it is ugly.
If that fixes it, you can look at various ways to permanently fix it.
Pulling Ethernet cables inside walls or under floors, or outside the walls (!).
Or switch to a better WiFi system — I have used Eero and swear by it, although I now have a wired house.
I’m fortunate to have a fully wired network. But my WiFi is rock solid using a Unifi setup. I can lock equipment to access points and much much more. I can run my core and endpoints and 15 other WiFi devices all on my WiFi without issues.
If the OP means 300mbps WiFi, then they need better WiFi equipment
It has less to do with your gear-setup. The radio environment, powerlevels, the channel conditions, interference who changes, even if you move sender or transceivers just a bit etc. count way more, how bad or good the wireless throughputs are…
I have a Naim Atom on 5 GHz wireless and a Nucleus+ wired to my wifi router. I can’t remember the last time it dropped, though I don’t have Tidal. My closest neighbor is about 200 feet away from me, so I don’t have much if any wifi interference from anyone else.
I did have more dropping issues in the past though. I thought older versions of Roon may have been at fault, but I can’t say that with certainty. I eventually discovered (with many hours of testing and luck) that my wifi router was troublesome.
I thought my wifi router was rock solid. It worked for everything else - web, video streaming, vpn for work, etc. and I never had a single issue. However, I found two songs that would always drop on the Atom at nearly the same time when played via Roon. Since my router was quite old, I finally decided to just get a new one. That resolved my issue, and those two songs now play all the way through. If your wifi router is old, you may want to consider a new one. Before doing that though, definitely try some of the other suggestions in this thread first if you can.
Your experience should definitely better than it sounds. Hope you can figure it out.
