Command/Powershell script to reset a network adapter

You can also restart a NIC using wmic command:

Get interface ID:

C:\>wmic nic get name, index

Disable NIC (InterfaceID:1):

wmic path win32_networkadapter where index=1 call disable

Enable NIC (InterfaceID:1):

wmic path win32_networkadapter where index=1 call enable

Thanks for the Info that it can be done with netsh.
I wrote a simple "Repair.bat" script:

@echo off
netsh interface set interface "%1" DISABLED
netsh interface set interface "%1" ENABLED

Just call it with the name of the NIC, renamed as i.e. "WLAN" so I does not have spaces, type "Repair WLAN" into cmd does the trick.
I'll place it into system32 and make a task of it or see how to integrate it into the network context menu...

The following command worked for me (on Server 2012 R2):

Restart-NetAdapter -Name "Ethernet 2"
Replace "Ethernet 2" with the name of your adapter.

Note: To create a PS script: create a new document in Notepad, save is as `script.PS1`, insert the line above and save. Right click the file -> Run with PowerShell.

See this article from The Scripting Guys, ["How Can I Enable or Disable My Network Adapter?"][1]

tl/dr:

Restart-NetAdapter -Name "Your Name Here"

You can get the list using

Get-NetAdapter
