We have a home with two levels. Deco is our system upstairs (3 modules). It is sourced by an Xfinity Gateway modem downstairs. When using just Wi-Fi mesh it was very slow, so I connected all the modules with ethernet as per the instructions in the app, and the speed is much better (10x faster or more). However, the airplay printers that were not connected directly to one of the modules dissappeared from my lists of airplay possiblities. I connected the printers directly to 2 of the modules, and they are now usable through airplay again. However, I also have an LG Smart TV that shows up as an airplay device, but will not connect to the iPhone or iPad wirelessly anymore since moving to the ethernet connection. Any suggestions?
