Dropped from 1000Mbit to 100Mbit



  • Today I reinstalled pfsense, because of squid wasn't uninstalled correctly.
    I hade no configuration done at all, so a reinstall seemed the fastest way to go.

    So, reinstalled with exactly the same configuration.
    pfsense says 1000Mbit on WAN and 1000Mbit on LAN, but I can only measure 100Mbit.
    Without the pfsense-router it goes up to 200 where it's supose to be.

    Any ideas?



  • Reinstalled again, reset BIOS but still only 100Mbit.
    The NIC is a DualPort Intel Pro 1000Mbit.

    The card works fine.
    Tested both ports in my dekstop = 200mbit
    Tested other cables and so on.

    Only thing left is checking the other hardware, but I don't see why it should have anything to do with this.

    Router hardware:
    Asus P5N-D
    E8600
    4Gb DDR2
    Intel PRO/1000 PT Dual Port Server Adapter

    Run 'top -SH' at the console while testing your download speed.
    Are you running out of CPU for some reason? You shouldn't be with that machine.
    Do you have a duplex mismatch between the WAN interface and whatever it's connected to?
    Bad cable? Is it exactly 100Mbps? Seems suspicious.  :-\

    It is strange.
    It worked before, same configuration, nothing has changed so why this is happening I don't know.
    Have to check the machine later this evening.

    Maxed out on 98Mbit/s



  • Aww..

    The NIC port 2 only gives 100Mbit. :(
    Why this now, the speed is 1000Mbit, says both the PC and the modem.

    Both ends set to auto detect speed and duplex?
    Your ISP decided to limit you?  ;)

    So all you did was reinstall, with the same version?

    Yes.
    Tried the card in my desktop.

    Port 1: 1000Mbit connection, 200Mbit measured
    Port 2: 1000Mbit connection, 100Mbit measured

    So the card is smoked, how it can indicate 1Gbit and deliver 100Mbit I don't know, probably firmware problems or a faulty circuit.
    Checked the physical port, but no problems visible.

    Warranty here we come!

    Huh, that is not something I would have thought of.
    Weird.  ::)
