So, i have been upgrading my home network over the last couple weeks with gigabit switches and CAT7 cables. my internet coming into my house is advertised as 500mb/s connection with Wide Open Web (ISP). my original configuration was from the modem, to the un-managed switch, to the terminal devices (computers, TVs, game systems and router). I got about 550mb/s to 630mb/s at my computer but I ran into an issue when the switch assigned IP addresses and changed the IP address for my home sever, so none of my devices could connect to it. I re-arranged it by placing the router in between the modem and switch to manage IP addresses, but when i speed tested on the same computer my network went down to about 86MB/s. My router is a D-link DGL-5500 and has gigabit LAN ports.
