    Hi alpimj.

    Could you post the results of these commands?
    Code:
    lsmod | grep -i e100
    
    apt-cache policy network-manager
    
    cat /etc/network/interfaces
    Regards.

    Please try:
    Code:
    sudo modprobe -r e100
    sudo modprobe e100 eeprom_bad_csum_allow=1
    dmesg | grep e100
    We are interested in messages after the timestamp above:
    [ 2.135164] e100: probe of 0000:03:08.0 failed with error -11
    If it works, we'll make it persistent.

    Are you ready to make it permanent?
    Code:
    gksudo gedit /etc/modprobe.d/e100.conf
    Add a single line:
    Code:
    options e100 eeprom_bad_csum_allow=1
    Proofread, save and close gedit. Now do:
    Code:
    sudo update-initramfs -u
    You should be all set.
