    Hi there,

    I have a serious problem with my laptop ASUS A52JB after the last BIOS upgrade. The LAN does not work at all, even after having reloaded Default profile with F10. It does not work with Linux, with Windows, with nothing :wallbash:
    The mainboard is a well know K52JB, with a dedicated chip JMicron jmc251 which controls both LAN and Card Reader.
    Interesting, the card reader works fine :confused:

    No success by downgrading the bios to any previous version: the LAN still not working

    Any idea here?
