    Question I realize the magnitude of all the "Can't Connect to Wireless" threads, butttt....

    I am a complete Newbie to this stuff, but I have an HP Pavilion Dv7, and like everyone else who is having problems, I too, cannot connect to the internet through wireless or through a cable. I've done a bit of research and I can see that each computer has its own quirks. I downloaded Ubuntu 11.04 from the "Windows Installer" and partitioned my drive. I know that my ethernet card isn't supported. Please help me.

    Well, you need to give some information.

    Press Ctrl-Alt-T to open a terminal and type

    Code:
    sudo lshw -C network
    Then post the resulting gobbldygook back here

    **note** you will have to type your password which you will not see as you type.

    You actually have a broadcom wireless card


    product: Bcm4312 802.11b/g LP-PHY


    You should be able to find what you need in post 3 of this thread

    Awesome! Thank you. I'll try these methods out tonight.

    Also, your Ethernet card can be made to work by installing a good, working driver, too.

    Download driver r8168 version 8.028. It is pretty easy to find via Google.

    Make sure you have packages build-essential and linux-headers-<your kernel version> installed on your system.

    cd to the r8168-8.028.00 directory and run "sudo ./autorun.sh"

    Your Ethernet connection should come up. Sometimes it helps to blacklist the r8169 driver.

    Wow! How nice to see being quoted for a solution! (probably for the first time!)

    However, as already figured out, that post assumes a working ethernet connection which is not the case here (damn this r8169 bug!!). Accordingly, TBABill's method seems most straightforward. Another alternative method (for no-internet connection) is given in the community documentation: https://help.ubuntu.com/community/Wi...nternet_access


    As for the ethernet issue, this post should be all that is required: http://ubuntuforums.org/showthread.php?p=11719747

    (the above linked post uses driver version 8.026... You might wish to get the latest one (currently 8.028..)from realtek's site: http://www.realtek.com/downloads/dow...&GetDown=false . The parts of commands that contain the driver/folder name would change accordingly.)

    The downloaded driver file (.tar.bz2) contains its own installation instructions in a README file which is just running:
    Code:
    sudo ./autorun.sh
    as ratcheer suggested. Normally, this should take care of everything, but some users have reported problems even after that, hence the alternate method I linked to above.

    I'll eagerly wait to see which methods worked for you.

    TBABill's method worked! Thank you so much! I'm so happy now haha.
