Gigabit Switch and 10/100 Router on the same network

Discussion in 'Server Networking' started by Graham Brooker, Aug 26, 2009.

  1. I have a NETGEAR DG834PN modem/router which has 4x 10/100mbps ports. I have
    2x gigabit Netgear switches. The NIC on my PC is a gigabit and so is the
    port on my NAS.

    If I connect the PC and NAS on the same gigabit switch should I be able to
    get gigabit speeds. It works if I directly connect PC to NAS without any
    other network hardware between.

    Do I have to upgrade my router to gigabit to get the NIC on my PC to show it
    is connecting at a higher speed than the old 100mbps rate?

    I cannot find a Netgear modem/gigabit router combination for the UK so I
    assume I just turn off NAT & DHCP etc on my existing modem and connect a new
    gigabit router to one of its ports instead.

    Any comments welcome.

    If two devices are Gb capable and are both connected to a Gb switch, you
    should get Gb performance. If the switch is 10/100, nothing connected to it
    can run any faster.

    On a Gb switch, you will only get Gb speeds between two Gb devices. Gb to
    10/100Mb devices will run at the lower speed.

    If you connect a Gb device to a port on your Netgear, it will not run at
    Gb speeds. This device is a essentially a 10/100Mb switch with a built-in
    modem. You would need to replace it with a Gb device to get Gb performance.
