Are you using a router or switch that supports 5G connections?
What router are you using? What cable?
If its a 1GB router/switch there is no gain with a 5G connection.
BUFFALO BS-MP2008 is an OK economy switch, just dont count on the trunking aspect.

Netgear Nighthawk X10 not for the wireless AD but because of the 10GB SP+ port

This allows me to connect my Aquantia 10G NIC via cat7 to the switch, 4x1GB aggregated connections to my NAS also on the switch then the 10GB SP+ fiber connection from router to switch. Then everything else connecting either wireless AC or the 1GB ethernet ports on the router.
