    No Internet at all

    Hi all, I am brand new to Ubuntu but have been scouring these forums for two straight days to no avail.
    I have 12.10 installed on a Toshiba laptop. I just installed it but even when wired no internet connection pops up. I cannot get wireless, I cannot get wired. Even when I installed the CD while wired it said no internet connection in the install wizard.
    I have tried installing 12.04 and 11.10 but the same issue occurred with those.

    I really want to be an ubuntu guy but I cannot even get on the internet. Help?

    Re: No Internet at all

    Thanks.

    Your laptop has network devices that are relatively new. I would advice installing 12.10.

    Wireless:
    Make sure your hardware wireless switch is ON. I have a Toshiba A665 laptop and the keyboard button to enable/disable wireless actually works.

    You may need to enable it by software also. Check this tutorial on how to use 'rfkill' to do that.

    Wired:
    Try loading manually the module 'alx', which will be available only on 12.10.

    Sources: here, here, and here.

    Let us know if you need more help with the process.
    Regards.

    Re: No Internet at all

    Hey, thanks for all the help. I checked the hardware switch and the light shows wireless as on. So I tried the rfkill list in terminal and the only thing it lists is bluetooth:

    1: hci0: Bluetooth
    Soft Blocked: no
    Hard Blocked: no

    I looked at the sources you sent me but all of those seem to rely on having some sort of connection to the internet. I do have another computer (which is how I am on this forum) so I can use a USB stick to transfer patches or fixes. Reading through the sources I just can't tell which one I need being a newbie.

    I'm confused why my wired connection would not appear. I plug directly into the modem and nothing shows up.

    Re: No Internet at all

    Let's make a test.

    Use the 12.10 installation media, and select 'Try Ubuntu' (Live).

    One you get to the desktop, open a terminal and run:
    Code:
    sudo modprobe alx
    wait a minute, and check is the module got loaded:
    Code:
    lsmod | grep -i alx
    If it is, it should display something. If it is not, the rest won't be useful.

    Then, restart your network:
    Code:
    sudo service network-manager stop
    
    sudo service network-manager start
    Try accessing the Internet with Firefox.

    If you have access, you may install Ubuntu from the icon on the desktop.

    Let us know how it goes.
    Regards.

    Re: No Internet at all

    Looks like nothing happened. See below. It won't pick up anything but bluetooth and this alx is not picked up at all. AHHH!

    One you get to the desktop, open a terminal and run:
    Code:

    sudo modprobe alx
    FATAL: Module alx not found.

    wait a minute, and check is the module got loaded:
    Code:

    lsmod | grep -i alx
    nothing appears for this code


    If it is, it should display something. If it is not, the rest won't be useful.

    Then, restart your network:
    Code:

    sudo service network-manager stop sudo service network-manager start

    Re: No Internet at all

    I should also add, when trying the alx thing I could not get onto the internet - either wired or wireless.

    Is there a way to download everything I need onto a thumb drive from my other PC and transfer it?

    Or is it possible to use a dongle with my cell phone?
