Hello @teknorob23 ,
Please refer to my original post. I am focusing on the router because it is broken. Everything else is fine. I am simply inquiring whether there is obvious opportunity for any sound quality improvement in case I need to replace it.
I have fine and stable sound with wifi streaming, no drops or buffering issues. I am just no longer able to control my router, that's what this is all about.
I intend to use the repaired or new router exactly the same way I use it now - through wifi and with all other current wifi devices. I have 10 or 11 wifi devices on the network including at most one smart TV concurrently with the streamer. No gaming or cameras. We have one desktop connected to the router via ethernet for my wife's business (zoom-type sessions). If I decide to use the Asus it will be connected to the desktop via the priority (gaming) port.
