    Ethernet card missing?


    Hi there, i am pretty new to linux, so please be patient with me...
    I can't get a connection with the lan cable.
    There doesn't seem to be a eth0 device:

    /sbin/ifconfig -a

    lo Link encap:Local Loopback
    inet addr:127.0.0.1 Mask:255.0.0.0
    inet6 addr: ::1/128 Scope:Host

    wlan0 Link encap:Ethernet HWaddr 00:19:7e:7d:f9:42

    Though there is a ethernet card:

    sudo lspci

    [sudo] password for b7h:
    [...]

    08:01.1 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 01)


    Any idea what is happening?
    I have ubuntu 12.04 LTS running on a dell latitude 131L

    Thanks for your help
