    Hello,

    I have the following:

    4.10 - Stable
    PIII 1000MHz
    3Com 3c905B-TX showing up as xl0

    plugged in using a etl certified (whooie) cat-5e to:

    Linksys EtherFast 4116

    Using ping -f /{some address}/, I've noticed at these configured speeds
    the following:

    10baseT/UTP half-duplex == 11% packet loss
    10baseT/UTP full-duplex == 30% packet loss
    100baseTX half-duplex == 70-80% packet loss
    100baseTX full-duplex == 95-99% packet loss

    Looking back at some older posts I see that this card seemed to have some
    problems, I was hoping though that someone had a idea or suggestion to get
    this card to go a tad bit faster.

    I have tried using media autoselect to which it goes to 100baseTX
    full-duplex. Unfortunately the card/switch don't talk like lovers after
    the first autonegotiation.

    Thanks!

    R.
