This is what someone told me in another forum. What is true about this? For 1Gbit LAN to work, you'll need GBLan adapters and cables (yes, these are different than "Normal" CAT-5 cables) in all devices on your network, including switches & routers. I did not think routers would affect it after it is hooked up to the switch. My network goes like this. Internet in to a 2wire modem/router-----gig switch-----computer-- also from the gig switch------ to another switch in another room------ to another computer, bluray, denon 3808CI, NAS(soon).
