I have pre-wired ethernet ports throughout my house that all connect to my ISP modem/router on the third floor. The main deco is wired on the second floor and the second deco is wirelessly connected on the first floor.

I am having issues with the connection on the first floor, so I wanted to test out access point mode to have the second deco wired to the ISP too. However, when I switch modes and connect the second deco to the ethernet port, I lose all internet from the decos.

Is it possible to have both decos wired to the ISP router? If so, how do I configure this?

Not sure if this would affect anything, but I was previously using router mode and noticed my devices getting confused with the ISP wifi and the deco wifi, so I renamed the different wifis like Wifi_1 and Wifi_2.

Thanks!
