I have a 100mbps ethernet connection setup right now, I was thinking about upgrading, my computers all seem to have gigabit capable network cards in them, my modem/router has one gigabit ethernet port which means I could upgrade to a gigabit capable ethernet router.
But I'm wondering if I need to upgrade my cables or if standard ethernet/cat5/cat5e cables are capable of gigabit connection speeds; and if they are, can they also be used for 10gbps connections? If not, what are the cables I would need for these scenarios called, and would these cables also fit into non-gigabit ethernet ports (i.e. 100mbps ports) without any compatibility issues (besides the reduced bandwidth)?
