• First, remove the r8169 module from the linux kernel.

# rmmod r8169

• Download the official realtek driver from here
• Unpack the download and install the driver as per the readme instructions included with the driver. Here’s the relevant part of the readme file; well, the “Quick Install” anyway:

Unpack the tarball :
# tar vjxf r8168-8.aaa.bb.tar.bz2
Change to the directory:
# cd r8168-8.aaa.bb
If you are running the target kernel, then you should be able to do :
# ./autorun.sh (as root or with sudo)
You can check whether the driver is loaded by using following commands.
# lsmod | grep r8168
# ifconfig -a
If there is a device name, ethX, shown on the monitor, the linux
driver is loaded. Then, you can use the following command to activate
the ethX.
# ifconfig ethX up

• Finally, blacklist the r8169 driver add the following to /etc/modprobe.d/blacklist.conf:

#blacklist r8169 driver
blacklist r8169
