This is how it is individually done. Hope you still need it or are interested =)
actual cmd.exe commands are in blue. The number you get from your wmic nic get name, index list is x
Start elevated Command Prompt. (administrator rights)
Get NIC list and index number: (using this commands is what tells you what x you are looking for)
wmic nic get name, index
Enable NIC with index number: (for example 7, or 12)
wmic path win32_networkadapter where index=x call enable
Disable NIC with index number: (for example 7, or 12)
wmic path win32_networkadapter where index=x call disable
for me I wanted to cycle the wireless usb internet connection which was device ID 12.
7 is my LAN adapter
