    I´ve noticed that some of the most recent 100Mbit cards I've been buying (Genius
    low end cards, model GF100TXR4) have only four connection points on the RJ45
    slot. However, the cards *do* work at 100Mbits. Anybody with the technical
    knowledge on the subject could please explain that? Why do 3Coms have all 8
    leads, while low-end use only 4? how does it affect the quality of connection?
    Are all 8 leads really used?

    Regards,
