Slow Internet Speed Through Netgear Switch (GS728TP)(V2)

Hello everyone,

  The problem I am have is slow internet speed through a new Netgear Switch (GS728TP)(V2). The setup I have is xfinity internet to a Netgear Nighthawk Modem (Model#CM2050V) to a Qnap Router (Model# QHora-322) to A Netgear Switch (GS728TP)(V2). I Get about 1,252Mbps Downlad speed & about 33.82Mbps Upload Speed from xfinity. If I plug my laptop into the Qnap Router I get the same speeds. But when I plug in to the Netgear Switch the speed drops down to 522.97Mbps Downlad speed & about 42.05Mbps Upload Speed. I tried difference patch cable (CAT-5 & Cat-6). But I always get the same results. When I Log into the router the port says the speed going out is 1G and when I Log into the switch it say the port is getting 1G. Any ideas would help.  Thanks
