Ubuntu 12.04 and RTL8101E/RTL8201E PCI Express Fast Ethernet Controller
I am completely new to linux. I have installed kxStudio on ubuntu 12.04 (upgraded from 10.x install). I was successfully booting with the kxStudio 3.2.0-33-lowlatency kernel.
All seemed well except for poor network connectivity. So I followed the instructions in post #3 (KomodoDave) here: http://ubuntuforums.org/showthread.php?t=1964200
Here is the gist of that post:
Add lineCode:sudo gedit /etc/modprobe.d/blacklist.conf
Unfortunately after taking these steps my computer will not boot using the low latency kernel (it stops with a black screen immediately after grub). It will boot using the 2.6.32-45 kernel.Code:sudo update-initramfs -u && cd ~/Downloads && tar xvf r8101-1.022.00.tar.bz2 && cd r8101-1.022.00 && sudo sh autorun.sh
Having booted with the 2.6.x kernel I commented out the 'blacklist r8169' line in blacklist.conf but the computer will still not boot using the low latency kernel.
I need the low latency kernel because 2.6.x does not see my usb soundcard. I also believe I will need the low latency kernel for audio work.
How do I best remedy this situation? I presume the first step is to recover the use of the low latency kernel. However, because I do not at all understand KomodoDave's final command I have no idea what to do.
I can only boot with the 2.6.x kernel. With this it appears (from lspci -v) the computer is using the r8169 drivers even if I have the 'blacklist r8169' line in blacklist.conf. I understand so little!
Also, I have removed and (re)installed the low latency kernel but no difference.
Also, I never was able to boot 12.04 using the default 3.2.0-34 kernel (it stops after grub with a blank screen the colour of the desktop). I had to use the 2.6.x kernel. However, before trying to fix the network card the pc did boot with the low latency kernel.
Low Latency Kernel Is Back
I took a punt and it worked - After commenting out the 'blacklist r8169' line in blacklist.conf I ran:
I am now again able to use the low latency kernel.Code:update-initramfs -u -k -all
So I appear to be back where I started - able to use the low latency kernel but with a poor network connection.
Any suggestions to solve my poor network connectivity much appreciated.
