@Beavis I now use a 4G SIM card in an Archer MR600 as the main router, and use an Ethernet cable to connect to a DECO M4R, with wireless connection to a second DECO M4R (3 devices). I do turn on both...

@TP_TechWriter Can a OneMesh router, such as Archer MR600, connected to a Deco Mesh router, such as Deco M4, through a ethernet cable? If so, can both routers use the same SSID? Thanks.
