Interface speed poblem



  • Hi, i recently install pfsense and put it to gigabit lan cards but in pfsense web managment page they stay on 100 mb/s, when i try to change speed to interfaces to 1 Gpbs my connection to the Internet stops when change WAN speed and it is same when change LAN interface speed cant log in to machine.Enyone can help me how to manage to run lan cards to 1Gpbs and my connection to lan and wan dosent stops?

    The pfSense WAN interface is connected to which device ?

    The pfSense LAN interface is connected to which device ?



  • WAN port is connected to the ISP device.
    Lan port is connected to the SW D-Link GO-SW-8G.
    I think the problem is actualy the SW, it is possible?

    The ISP device might only be 100M.

    You should probably set both interfaces to Default (no preference, typically autoselect)

    Also make sure both patch cables are known-good, 8-conductor Cat5e or better.



  • Is it possible bcs the SW is a little stupid when i change manualy speed  interface in pfsense  dosent work or problem to be from the cable?
    Bcs when i change WAN interface speed to 1 Gps it shows red x.

    Your first suspect should be the cables.  The switch you're using is a gigabit switch, you should be getting gigabit at least on the LAN.  WAN is a different story, the hardware provided by your ISP may only handle 100 Mbps, depending on the speed you're paying for.

    Especially suspect the cables if forcing gigabit mode on the LAN interface causes it to disconnect as you're seeing.

    If the cables are good, then you might have an issue with the gigabit cards you installed in the box.  (The BSD driver might not want them to go into gigabit mode).  Unlikely this is the problem, but not impossible.
