http://ccm.net/ has an example of how to do this. In that example they are using a '*'. Does it work if you add that to your command?

The following is from http://ccm.net/faq/1886-enable-disable-a-device-from-the-command-line

Display all the devices in the system

In the command prompt, type

devcon find *> list.txt

To get the list in a file For example, my network card Accton appears as:

PCI\VEN_1113&DEV_1211&SUBSYS_12111113&REV_10\3&13C0B0C5&0&48: Accton EN1207D Series PCI Fast Ethernet Adapter #2

Choose a piece of the string that identifies the device, and verify it is unique:

c:\>devcon find *VEN_1113     
PCI\VEN_1113&DEV_1211&SUBSYS_12111113&REV_10\3&13C0B0C5&0&48: Accton EN1207D Ser     
ies PCI Fast Ethernet Adapter #2     
1 matching device(s) found.

Make sure that "VEN_1113" means a single network card. devcon disable *VEN_1113

Enable/disable the device

devcon disable *VEN_1113      
devcon enable *VEN_1113

This allows me to enable/disable my network card (and therefore my internet connection) from the command line.

I have tried your example but it is no use. `C:\Users>devcon find =net "*DEV_8168*" PCI\VEN_10EC&DEV_8168&SUBSYS_368217AA&REV_07\07000000684CE00000: Realtek PCIe GBE Family Controller 1 matching device(s) found.'` `C:\Users\zhilu1234>devcon disable "*DEV_8168*" PCI\VEN_10EC&DEV_8168&SUBSYS_368217AA&REV_07\07000000684CE00000: Disable failed No devices disabled.` — wuhlcom, Jul 13 '15 at 06:08
Why the apostrophes and ending star? You wrote: devcon disable "*DEV_8168*" — Magnus Karlsson, Jul 13 '15 at 08:49

I downloaded another devcon by following this, which solved the problem!

Download the “Windows Driver Kit (WDK) 7.1.0 from Microsoft: http://www.microsoft.com/download/en/details.aspx?id=11800
Download http://7-zip.org/
Mount the WDK ISO
Double click WDK\setuptools_x64fre.cab
Copy _devcon.exe_00000 to a temp folder
Rename _devcon.exe_00000 to devcon.exe
Move devcon.exe to C:\windows\system32
