    You need to change the device priority in you BIOS to CD as first boot device. Please note, that the point release of 12.04.2 ships kernel 3.5 per default

    Re: Cannot connect to ethernet with wired connection

    I made a mistake and didn't turn off computer with disk inside, I just rebooted and didn't get the disk to boot. All is well now. I just need further instructions to proceed with fixing the 12.10 64 bit installation of the ethernet.

    You will probably need to set the BIOS so that the first boot device is the CD instead of the harddrive.

    Re: Cannot connect to ethernet with wired connection

    I'm having a similar problem here. I've just installed 12.04 (64 bit) on an ASUS X55A laptop - that's a few hours ago, so I only have the Base 12.04, with no updates and no ability to update. I can't connect to my LAN, but can see lots of wifi connections. None of them mine - I don't have wifi. I don't have any option in my BIOs to enable or disbale LAN. So, I can't access internet at all via the laptop, only from my pc and then try to build using a USB stick.

    So I guess this is a repeat of the atheros driver, although I checked the ubuntu page before I bought it to read that the ASUS X55A is a supported product?

    Any ideas, or is there a better/other linux distribution I should go for?

    Thanks in advance

    You will have an infinitely easier time if you can get the wireless going. Is the hardware switch on or off?
    Code:
    rfkill list all
    I solved a case a few days ago where the person could connect easily after he turned off N speeds in the router. Please try.

    If the intent is to install 12.10, upgrade the linux-image to 3.5.0-25 which includes alx, which is what I recommend, then you need to go ahead and install. I assume your mouse is working well in 12.10.

    Hi Chili555. I have no wireless...it's neighbours...it's Germany, everything's passworded, people don't like to share!
    rfkill list all shows
    0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
    1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    I'm not sure what you mean by 'turning off N speeds in the router'. The 'base' is on my wife's mac....but I've had no problems since installing 8.04 on my machine and have upgraded ever since with never a problem to connect to our dsl router

    Let's see if we can solve this first. Please do:
    Code:
    sudo rfkill unblock all
    rfkill list all
    Is the soft block fixed? Does the wireless work now?

    I don't quite understand the wireless at the neighbors or the 'base' is on your wife's Mac. Do you have any wireless capability at all, no matter where?
