RTL8111/8168B fix script for ubuntu

[jaybutts]

Using the Network Interface Card on my motherboard the RTL8111/8168B.

I found I had network issues dropping packets often 100% and being disconnected all the time I found that this problem has been ongoing for awhile and the kernels from 2.6 to even 3.2 load the wrong module for some reason it loads the 8169 driver module.

I have written a script to fix it for me and for you after each upgrade. Please spread the good word

How to tell if you are effected by this bug:

If the command

lspci|grep r8168

returns the result -

05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

ANDIf the command

lsmod|egrep "r8168|r8169"

ALSO returns only the the 8169 and not the r8168 kernel module.


Below is the stable version 0.1.1 [Release Date April 1st 2012] and it is tested for upgrades and new installs on ubuntu 11.10 and 12.04 BETA.

Instructions.

Copy the script to a new text file
Save the file as 81681fixer.sh
go in a terminal to where you saved the file
run the file with this command:

 chmod+x 81681fixer.sh; sudo sh ./81681fixer.sh

#!/bin/bash
is8168=$(lspci|grep 8168|wc -l);
isusing8169=$(lsmod|grep 8169|wc -l);
isroot=$(whoami|grep root|wc -l);
isblacklisted=$(grep r1868 /etc/modprobe.d/blacklist.conf|wc -l);

if [ $isroot -ne 1 ];
then
echo "You are not root please run 'sudo su -' or su before running this script";echo "script must be run as root";
exit 1;
fi
echo "Checking that you are root user";
if [ $is8168 -lt 1 ];
then
echo "Your NIC is not RealTek 8168 this fix does not apply to you";
exit 1;
fi
echo "Checking that your Nic is an 8168";

I will test this soon as I have to upgrade my kernel already and make any fixes plus add some things like ping tests and uninstall option. There could actually be syntax error as I haven't even run it once.

Great job, I hope it works!

I also hope it will soon become moot, because my ethernet connection has been doing just fine with r8169 in the kernels used by Precise.

Well that is good to hear

Any suggestions or modifications are welcome.

isblacklisted=$(grep r1868 /etc/modprobe.d/blacklist|wc -l);

This line should be:

isblacklisted=$(grep r1868 /etc/modprobe.d/blacklist.conf|wc -l);

Am I right?

Yep, thank you, fixed that.

[ahendriks]

Okay, furthermore:

if [ $is8168 -ne 1 ];
then
echo "Your NIC is not RealTek 8168 this fix does not apply to you";
exit 1;
fi
if [ $isusing8169 -ne 1 ];
then
echo "Your nic is an 8168 but its not using 8169 driver, this fix doesn't apply to you";
exit 1;
fi

You mixed up is8168 and isusing8169? You should have an 8169 card and using a 8169 to apply the fix, am I right? You check if it is a 8168(!) card and using a 8169 driver. You should have a 8169 card and a 8169 driver... ?

[ahendriks]

Shoudn't the blacklist be done earlier in the proces... I believe so... dunno for sure...

Oh yeah, very, very, very good thread! Many thx if this works!

Yes your right, I changed the 1's to 0's, this is how I originally had it but for some reason I changed it.

hmm why do you think that? If we do it early then it will have blacklisted on a failed install.
