Enable/Disable Network Connection

  • Artikel

Whilst waiting for lunch, i stumbled across this post on Channel9, https://channel9.msdn.com/ShowPost.aspx?PostID=158556. It is c# code for enabling and disabling network adapters. I thought you must be able to do this with PowerShell easier.

In Vista there is a win32_NetworkAdapter wmi provider - whoop. Problem solved.

 PS C:\> Get-wmiobject win32_NetworkAdapter | format-table

will get you a list of adapters installed on your machine. My wireless adapter was deviceId 5, so this line gets me the device

 PS C:\> Get-WmiObject win32_networkadapter | where {$_.DeviceId -eq 5}


ServiceName      : NETw2v32
MACAddress       : 00:13:CE:8A:4B:C5
AdapterType      : Ethernet 802.3
DeviceID         : 5
Name             : Intel(R) PRO/Wireless 2915ABG Network Connection
NetworkAddresses :
Speed            : 11000000

Saving this to a variable to work with is easy

 $wireless = Get-WmiObject win32_networkadapter | where {$_.DeviceId -eq 5}

Now i can interact with my wireless adapter and do such things as

 $wireless.Disable()

 $wireless.Enable()

Cool - add the variable to your profile and everytime you open up powershell you can interact with your network adapter, no C# console. No VBS to run. Nice clean and simple.

    I've just looked on my XP machine and it appears that Disable is not supported on XP. It must be new to Windows Vista.
