I am updating my home WiFi from an old Airport Extreme to a Netgear Orbi Mesh WIFi system. In my old setup I have been using the Airport Extreme with an Airport Express in client mode connected to an old stereo receiver, allowing me to Airplay music to the receiver. Now I am wondering is there is any way to continue to use the Airport Express with the new Mesh WiFi router. I imagine connecting them by ethernet is an option, but it would be difficult to run the wire. Is there any inexpernsive way to save the problem of how to wirelessly play music on the old receiver? I also have an unused Apple TV to throw in the mix, but my receiver does not have any optical audio inputs.
