I have an Asus 4G-AC53U router but after factory reset I cannot create a SONOS net by wiring my Play 1, whiched has worked earlier. I cannot either add a new SONOS boost. Both units start up and is showing on router interface client list with IP adress. The speaker even continue to play music. The Play 1 works fine close to router over WiFi but the Boost cannot be added at all.
