Haven’t tried that. The router is at the other end of house. I use 4 Google mesh units for the wireless and have great strong internet.
That may well be your problem. Have you really tested that Mesh system? I have done some reading on it. Google Mesh is mainly about coverage and not through put.
In any event for AV work I have found Wi-Fi far inferior to hard wire. Even right next to a very good and powerful router Wi-Fi does not test like hard wire. I now use hard wire to AV systems no matter where located.
Test your system by using
DSL reports at your receiver location point. Use DSL Reports and not other testing systems which give you a false sense of performance.
My view is that Wi-Fi systems are over hyped and under performing and you don't get the performance you think you get.
As systems develop and get more complex, as per your receiver for instance, more and more are advocating going back to wired rather than wireless connection.
