I recently started using a gigabit switch alongside my TP-Link router. My room is setup like a LAN area, with a desk long enough for 4 pc's, so I have 4 cables running from the switch to the computers. My router is providing DHCP and has a PS3 and VOIP phone plugged up to it. Is there anything blaring that would cause the machines not to transfer files at gigabit speeds? Currently they transfer at 10-12mbps, which is normal for a 10/100 connection. Anything I'm missing? I can get into a lot of detail, but I need to know what needs to be told.
