Configuring a gateway modem & RT-AC68R for DLNA

[BHZizou]

Hi,

I have a Ubee DVW3201B gateway modem in one of my rooms & using it to connect to 4 devices via ethernet cables. Three of those ethernet cables are connected to a PC & two Smart TV's, while the 4th cable connects to a recently purchased Asus RT-AC68R router (living room)... LAN-to-WAN method, which then connects to an Xbox One & another Smart TV (both wired connections).

I already have wireless disabled (but still in NAT mode) on the Ubee gateway modem, and would like to find the best way to configure my home network, so that way I can keep all 5 already mentioned wired connections (in order to get full HSD speeds), stream stuff (DLNA) between them & other wireless devices (laptops, cellphones and possibly a printer) which will be connected wirelessly to the Asus RT-AC68R router... also connected to an external hard drive via USB 3.0 port.

Would I benefit if I switch to LAN-to-LAN method... and are there any other features on this router that could be enabled in my case?


Any suggestion will be highly appreciated...
