ubuntu network with p8p67 motherboard (rtl8111e LAN)

Got new motherboard: asus p8p67 with realtek 8111e Gigabit LAN controller. On ubuntu the network works ugly - sometimes it doesn't connect to google and some other sites.

The problem is that ubuntu loads wrong driver for the network - r8169 instead of r8168. The solution is to download correct driver from realtek website and use it.

1. Check to see if the r8169 module is loaded
   

   lsmod | grep r816
   r8168 41104 0 
   -> lspci -v
   01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
   Subsystem: ASRock Incorporation Device 8168
   Kernel driver in use: r8169
   Kernel modules: r8169
   

2. Download the official Realtek driver
   Realtek RTL8111/RTL8168
   
3. Remove the r8169 module
   

   -> rmmod r8169
   -> mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko ~/r8169.ko.backup
   

   ( the ` is a backtick, it is not an apostrophe or single quote )
   
4. Build the new r8168 module for the kernel
   

   -> bzip2 -d r8168-8.009.00.tar.bz2
   -> tar -xf r8168-8.009.00.tar
   -> cd r8168-8.009.00
   -> make clean modules
   -> make install
   

5. Rebuild the kernel module dependencies
   

   -> depmod -a
   -> insmod ./src/r8168.ko
   

Remove the r8169 module from initrd

-> mv /initrd.img ~/initrd.img.backup
-> mkinitramfs -o /boot/initrd.img-`uname -r` `uname -r`

6. Add r8168 module to /etc/modules
   

   -> echo "r8168" >> /etc/modules
   

   
   Reboot, You are done!
   
7. Examine that ONLY the r8168 module is loaded for the interface
   

   -> lspci -v
