Hi

i have a 3 deco xe75 pro. When connecting by Ethernet  to my Virgin router/modem they all show up as connected by Ethernet cable. When I connect them via a switch, the 2nd and 3rd deco's alternate on which one is Ethernet and which is by WiFi. Ideally I want them both on Ethernet, any ideas? I have put them in access point mode too, but whether or not in this mode, they do the same thing. 

Thanks
