Enable/Disable Network connection

[Danyfirex]

I was needing to enable and disable a network connection. I google and find a good C++ example using interfaces. so I ported to Autoit (ObjCreateInterface  )

Cool. It's better than netsh.

_{But the depth of the blocks if a little strange. Why not just write If Not .. Then Return False}

[Danyfirex]

Rewrite it as you want. for that is the source

Sure something like this would come in handy at some point, except it does not appear to work for me, meaning the connection is not disabled, or indeed enabled.

Win 7 32

$oNetCManager:1

$pIEnumNetConnection: 5543260

$oIEnumNetConnection: 1

$pConnection: 5543404 $iCount: 1

$oConnection: 1

$pConnection: 5543404 $iCount: 1

$oConnection: 1

Very impressive (as usual)!

Thank you for sharing.

Also, better than WMI ....

¿Do you get some return value? I made the code in window 7 x64. Thanks for report. I'll check in Windows x86 Saludos

Great job!

I've checked in windows 7 x86 and work correctly.  be sure that your're running with  admin rights. Saludos

Yes, my mistake, works just fine using #RequireAdmin.

Thanks.

I found my best solution :

Site web : https://social.technet.microsoft.com/Forums/windows/en-US/b4a3c5ad-6c5d-4d83-bcd6-df12d8aea5a1/enabledisable-all-network-connections-using-cmd

Disable:
wmic path win32_networkadapter where PhysicalAdapter=True call disable

Enable:
wmic path win32_networkadapter where PhysicalAdapter=True call enable

[JohnOne]

That disables all adapters.

[pSKratCH]

That disables all adapters.

 

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
