I am living in Bali and want to upgrade my LAN/Wi-Fi in our new house. I am thinking about purchasing the DECO X75-AX5400; however, Bali, Indonesia does not have Wi-Fi 6 yet.  I am considering this model due to it's strong signal and our walls are concrete. I know that the units are backwards compatible wit my M4 and E4 units that don't use Wi-Fi 6 or 6e; however, can some confirm if the X75-AX5400 system will work in Bali before Wi-Fi 6 is available.  I want to set up a system with the strongest signal without using older technology.
