Question no internet connection with lubuntu 14


Hello, I've a problem with my ethernet connection.

After installing lubuntu 14 I've noticed I've not ethernet connection to my router.

I tried to remove Network Manager and setting "interfaces" to dhcp but no way.
The same using static.
I've also tried to make dhclient, but the pc continues to searc with no response.
I use a Packard Bell i media 2 Ghz with Nvidia MCP 61 Ethernet Card.
Thanks in advance.

I found a thread which indicates this card might have a Broadcom chipset.

Run the command lspci from a terminal and report back what it says about the wireless chipset.

mauropegolo, your post is very, very confusing:

i cannot make any sense of this. sorry.
what internet connection is not working?
do you have any internet connection?
how EXACTLY did you try to fix it?
your description is just a brief and confused summary.

btw, if you are talking about ethernet, that is NOT wireless.

Modprobe for realtek maybe.

Boot to the live cd/dvd and see if it is connected correctly.

The driver is in the second link--
