    Re: 12.04 and RTL8101E/RTL8201E

    If the 3.2 kernel has always been booting to that screen, perhaps that's a separate problem - the video. I'd try one of the video boot options to see if it will boot. But you need to decide which you want - the old kernel with working wireless, or if you're willing to work with getting the newer kernel running and the wireless working.

    Didn't mean to intrude on your great work chilli555 - just thought perhaps the kernel issue is separate from the wireless.

    Yes, it compiled without complaint

    Just to be clear - I am using a wired connection. It is true that I have never been able to start 12.04 with the default kernel.

    Currently, I cannot boot with any kernel. When I select 2.6.x at grub the pc displays:
    Code:
     BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4.1) built in shell (ash)
     Enter 'help' for a list of built in commands
     
     (initramfs)
    [I have unplugged exyernal hardware (usb drive & usb soundcard) but no difference. The other kernels result in a blank screen.]

    Ok something odd is happening. I guess I have done something stupid in my install/upgrade process. I am going to install a fresh 12.04.

    Thanks for your help

    After a fresh install I was able to install the r8101 drivers.

    Unfortunately I am still experiencing poor network connectivity. I have started a new thread for this: http://ubuntuforums.org/showthread.php?t=2096614

    Re: 12.04 and RTL8101E/RTL8201E

    Hey, I am having a similar problem. I have just done a fresh install of 12.10 on a toshiba satellite c850d duel booting with windows 8. I have no wireless connection. It doesn't show in the top panel or the network settings. I replaced the r8169 driver with r8101 as recommended in this thread. Unfortunately I still don't have any sign of my wireless. Below is the output from what I did.

    Of course not. These are wired ethernet drivers. Please post your own new thread and include:

    Re: 12.04 and RTL8101E/RTL8201E

    I am trying to get the RTL8101E/RTL8102E wireless in my Toshiba Satellite 855c with Ubuntu 12.10 working but so fat without success.

    I did your download of r8101-1.022.00.tar.bz2 and followed the instructions you gave. All seemed OK until I got to your instruction to:

    sudo update-initramfs -u && cd ~/Downloads && tar xvf r8101-1.022.00.tar.bz2 && cd r8101-1.022.00 && sudo sh autorun.sh

    which produced the output:

    update-initramfs: Generating /boot/initrd.img-3.5.0-26-generic
    r8101-1.022.00/
    r8101-1.022.00/src/

    r8101-1.022.00/autorun.sh
    r8101-1.022.00/Makefile

    Check old driver and unload it.

    Unless someone has got a better idea, I'm thinking I'll try one of those wireless dongles, though these seem for the most part to be a similar pain to get working. If KomodoDave's excellent solution cannot work in this case, is there one of these dongles that can be recommended?
    Many thanks.

    Re: 12.04 and RTL8101E/RTL8201E

    RTL8101E/RTL8102E is not a wireless device, it's ethernet. Would you please tell us what your wireless really is?
