    Ubuntu 12.04 doesn't read ethernet cable and I cannot activate wifi driver

    Hi! I have an Hp mini 1000 with XP. I installed Ubuntu 12.04 LTS (32 version) but I don't have wifi. I plugged my netbook to my ethernet cable but it doesn't read it either.
    I read another posts to try to fix it by myself but I was unsuccessful.
    I tried the following codes:

    rfkill list all

    0:hp wifi: wireless LAN
    soft block:no
    hard block:no
    1::hp wwan: wireless wan
    soft block:yes
    hard block:no

    lspci --nn | grep 0280

    lspci:invalid option -- '-'
    usage:lspci [<switches>]

    Any help will be greatly appreciated . Thanks

    Re: Ubuntu 12.04 doesn't read ethernet cable and I cannot activate wifi driver

    lspci --nn | grep 0280

    lspci:invalid option -- '-'
    usage:lspci [<switches>]
    It is actually:
    Code:
    lspci -nn | grep 0280
    Not --nn. Since we're also looking at ethernet, please let us see:
    Code:
    lspci -nn | grep -e 0280 -e 0200
    Thanks.

    We see no ethernet yet. Let's widen the search:
    Code:
    lspci -nn

    We still see no ethernet. Does your device actually have one? Is it defective? Is it enabled in the BIOS?

    Let's fix the wireless without ethernet. Please download this file on any other computer. Transfer it on a USB key or similar and drag and drop it to the desktop. http://mirrors.kernel.org/ubuntu/poo...e_1.11_all.deb

    Now we install it:
    Code:
    cd ~/Desktop
    sudo dpkg -i linux*.deb
    Now unload and reload the driver so it sees the shiny new firmware:
    Code:
    sudo modprobe -r b43 && sudo modprobe b43
    Your wireless should now be working.

    I downloaded the file to my USB. I followed all the steps that you mentioned Chili555 and when I opened network folder suddenly appeared wifi. So it is working right now.
    Thanks a lot Chili555
