I have a Compaq Presario CQ-61 320SQ, I am using Ubuntu 10.04 because after update to 10.10 my mouse and touchpad won't work, network won't work, sound won't work ... (I managed to fix most of them after almost a month of googling, but not all, my 2 Desktops have no problem with 10.10) so I decided to switch back to 10.04, where I have a problem:

My broadband speed is very low beacause of the kernel module r8169, I downloaded the good module r8101 and every time the computer boots have a rc.local entry to fix this.

Can I load the modul permanently from a specific location. I heard about /etc/modules but there I need the module name, but I have to load it from a specific path (where is the default path for that) ?

Thank you.

So I studied the script:

It creates the file r8101.ko in /lib/modules/`uname -r`/kernel/drivers/net so I think as long as nobody will delete that file, and I don't update the kernel, maybe adding r8108 to /etc/modules will work, and add r8169 to blacklist ... I will give it a try.

So I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf. It still uses the old module.:

radu@adu:~$ lsmod | grep r8
r8101                  67626  0 
r8169                  34108  0 
mii                     4381  1 r8169

EDIT: The module is loaded using this script that came with it.:


# invoke insmod with all arguments we got
# and use a pathname, as insmod doesn't look in . by default

TARGET_PATH=/lib/modules/`uname -r`/kernel/drivers/net
echo "Check old driver and unload it." 
check=`lsmod | grep r8169`
if [ "$check" != "" ]; then
        echo "rmmod r8169"
        /sbin/rmmod r8169

check=`lsmod | grep r8101`
if [ "$check" != "" ]; then
        echo "rmmod r8101"
        /sbin/rmmod r8101

echo "Build the module and install"
echo "-------------------------------" >> log.txt
date 1>>log.txt
make all 1>>log.txt || exit 1
module=`ls src/*.ko`

if [ "$module" == "" ]; then
    echo "No driver exists!!!"
    exit 1
elif [ "$module" != "r8169" ]; then
    if test -e $TARGET_PATH/r8169.ko ; then
        echo "Backup r8169.ko"
        if test -e $TARGET_PATH/r8169.bak ; then
            while test -e $TARGET_PATH/r8169.bak$i
            echo "rename r8169.ko to r8169.bak$i"
            mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i
            echo "rename r8169.ko to r8169.bak"
            mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak

echo "Depending module. Please wait."
depmod -a
echo "load module $module"
modprobe $module

echo "Completed."
exit 0

So to gather all the data to an answer, here it is:

  1. After the first compile of the new module, I had the module file r8101.ko in /lib/modules/$(uname -r)/kernel/drivers/net.

  2. I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf but I was still booting to the old module.

  3. Then I run sudo update-initramfs -u and then after restart the new module was loaded as expected (thanks to @papukaija comment).
