You can try it with these shell commands:
netsh interface set interface "Network Adapter name" DISABLED <br />
netsh interface set interface "Network Adapter name" ENABLED
Of course, I can't guarantee it will work.
Here's a link describing different tings you can do through WMI:

Keep in mind that it's up to the driver software for the NIC to provide the
Enable
and
Disable
methods for the
Win32_NetworkAdapter
class, and 99 times out of 100, the driver does NOT provide these methods.
