I'll buy this sistem to my home. I have my home all wired and ready for this, so this system will be used with ethernet cables, I saw that DECO M9 PLUS allows to do that.
My main concern about this is, If this works if one wireless module is connected to my ISP and not to the Deco main module. For example, I have my ISP, and one LAN will be connected directly to one deco wireless module ( not the main one ). So it will be something like this :
ISP - Main Module - Module 1
ISP - Module 2
