Install ethernet driver under debian

[Angelica Maria]

Hello,
I have a motherboard Gigabyte GA-M720-US3. I get to log Internet but network-manager brand "device unmanaged. During installation I had to squeeze a point about the non-free module r8169. I install firmware-linux-nonfree and linux-headers-2.6.32-3-686 then did a modprobe r8169 but it doesn ' has done nothing.
Here's what lspci gives me:
Code:

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)

Can you help me to manage the connection by network-manager? Thank you for your help.

Hello,
For network manager takes hold of your Ethernet interface, it is necessary to comment in / etc / network / interfaces and restart Network Manager. Now, all this can be manip useful on a wireless connection or you are bothered by a generally key wep / wap, both on an ethernet connection, you can leave like that.

Hello,
Even I do have a similar kind of a problem with my debian operating system. Well the problem is that I can use vpn and everything at once is very annoying
Here's what's in the file / etc / network / interfaces:

# This file Describes the network interfaces available on your system 
# and how to activate them ". For more information, see interfaces (5). 

loopback network interface # The 
auto lo 
inet loopback iface lo 

# The primary network interface 
allow-hotplug eth0 
iface eth0 inet dhcp

See, if you can help me with this.

Hello,
I think you should comment the following two lines in your file and see if it works

allow-hotplug eth0 
iface eth0 inet dhcp

Network manager will take control of your Ethernet card eth0 (after a restart the service or pc). Just comment the two line and see if it works or post back with error.

Hello,
And if you missed it some packages for the type of vpn you desire .... ? Some random words: openvpn, pptp, vpnc. I am trying to say that if you have not installed some of the packages which are related to these then it can give some problems, though I am not sure what packages they may. So, you try to do the clean install again will all the suggested dependencies and see if it works.
