I've got a cable modem with an output of 10/100, a wireless router with 10/100 jacks, a TimeCapsule, and a D-Link Gigabit Switch. I was given the Gigabit unit to "speed things up", but it seems to me that this will have no effect at all, since the source of my data, the cable modem, is limited to 10/100. Would there be any benefit at all to having the Gigabit switch off the cable modem and it *possibly* relieving some congestion between all the computers and printers and tivo and stuff talking to each other? Assuming one or more of them actually can support gigabit traffic? Or is my original simple-minded assumption correct -- it'll make no difference at all no matter how I hook all this stuff up? TIA!
