Got the AC1200 two Decos today and I succesfully create a new WiFi Mesh. My question is: Since I have two decos, one of them (main) have to be connected with an Ethernet cable to my main Router from my ISP Orange? The Router is a LiveBox given by the company.
My first interest was to create the Mesh WiFi and then using both Decos as Repeaters, since I dont have a huge home (130m2)
When I disconnect main Deco from the wired ethernet cable to my main Orange router, the light turns into red...
Thank you for your help and excuse my ignorance.
