    Broadcom BCM57785

    I'm new to linux, so don't be really hard on me. I bought a new laptop - Acer Aspire v3-571g intel-corei3-3110M. I tried to install different linux distros: pear os, elementary os luna and ubuntu finally. In all cases it says "Connected" to my wired internet, but actually the internet isn't working. I really don't know what to. On my old Acer laptop installed Ubuntu and the internet works like a charm. Maybe I have to install ethernet drivers? Please, help me.
    I set up outputs that I saw in other threads is most requested for help, but I'm not sure what those commands mean:

    Code:

    Re: Broadcom BCM57785

    Hi,

    is the driver loaded?
    Code:
    lsmod
    please also check:
    Code:
    cat /etc/network/interfaces
    cat /etc/resolv.conf
    route -n
    Is wireless working? If yes, install this package and show additionally:
    Code:
    sudo apt-get install ethtool
    sudo ethtool eth0

    This may mean that the package is missing, has been obsoleted, or
    is only available from another source
    
    
    E: Package 'ethtool' has no installation candidate
    I don't have a wireless connection, I only can see the users in list that are connected to wi-fi network. But to be sure I did the last command.

    I assume I had to connect my cable to the new laptop in order to check the last command, which I did (sorry I'm saying those stupid things):

    Re: Broadcom BCM57785

    For additional information: I'm currently typing all of my posts on my old laptop, where this wired connection is working; I'm also downloading from there, then I'm putting info on my flash usb; and also all of the output from my new laptop I put on this flash drive in .txt, go back to this old laptop in order to write here.

    Try to deactivate the auto-negotiation of the card:
    Code:
    sudo ethtool -s eth0 speed 100 autoneg off
