Command/Powershell script to reset a network adapter

Question

OS: Vista enterprise

When i switch between my home and office network, i always face issues with getting connected to the network. Almost always I have to use the diagnostic service in 'Network and sharing center' and the problem gets solved when i use the reset network adapter option.

This takes a lot of time (3-4 min) and so i was trying to find either a command or a powershell script/cmdlet which i can use directly to reset the network adapter and save myself these 5 mins every time i have to switch between the networks. Any pointers?

You can use WMI from within PowerShell to accomplish this. Assuming there is a network adapter who's device name has Wireless in it, the series of commands might look something like the following:

$adaptor = Get-WmiObject -Class Win32_NetworkAdapter | Where-Object {$_.Name -like "*Wireless*"}
$adaptor.Disable()
$adaptor.Enable()

Remember, if you're running this with Window's Vista, you may need to run the PowerShell as Administrator.

Zitrax's answer:

netsh interface set interface "InterfaceName" DISABLED
netsh interface set interface "InterfaceName" ENABLED

was 99% of what I was looking for. The one piece of information that s/he left out, though, was that these commands have to be run as an administrator. Either run cmd.exe as an admin and type them in, or store them in a batch file, and then run that file as admin by right clicking on it and choosing "Run as Administrator" from the context menu.

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

tl/dr:

Restart-NetAdapter   -Name "Your Name Here"

You can get the list using

Get-NetAdapter

Solution 4

You can also try this in a .BAT or .CMD file:

ipconfig /release
ipconfig /renew
arp -d *
nbtstat -R
nbtstat -RR
ipconfig /flushdns
ipconfig /registerdns

These commands should do the same things as the 'Diagnose and Repair' for the network adapter, but is WAY faster!

Let me know if this helps! JFV

What worked for me:

netsh interface show interface

to show the interface name which for me was "Ethernet 2" and then:

netsh interface set interface "Ethernet 2" DISABLED
netsh interface set interface "Ethernet 2" ENABLED
