Broadcom BCM57785

[ksjenka]

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:

Thanks to all who are helping people here

[praseodym]

Hi,

is the driver loaded?

lsmod

please also check:

cat /etc/network/interfaces
cat /etc/resolv.conf
route -n

Is wireless working? If yes, install this package and show additionally:

sudo apt-get install ethtool
sudo ethtool eth0

[ksjenka]

OK, that's the info I got:

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.

[praseodym]

Which Ubuntu version is it? Please show

uname -a

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):

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.

[praseodym]

Try to deactivate the auto-negotiation of the card:

sudo ethtool -s eth0 speed 100 autoneg off

[ksjenka]

Nope, nothing's changed
