Newbie here so probably silly question. I have Deco M4 (1 main plus 3 clients) which I've been able to successully install in Access Point Mode throughout a solid brick and concrete 2 story home. Everyhing checks out ok. So here's the question. When I connect a device (ie iphone, Apple TV, Mac Mini, WiFi printer etc) to WiFi do I use the SSID created for the Deco network, or my main router SSID? Grateful for any input please. Many thanks.
