Plex bandwidth

I recently decided to hard wire my entire network and set static IPs through a gigabit switch with the router only handling connection to the internet. DHCP is disabled on the server and my file server and I manually set them up. Now I get strange results when checking the dashboard. It shows only 4kbps bandwidth but I am getting full 720p resolution on all my players. Is this normal. Windows 10, Linksys WRT3200ACM router, D-Link DGS-1016D switch.
