Which is most important? dis- and re-enabling your connection? or
doing so only when the computer is "idle"? The former is relatively
simple and can be done using a variety of scripting techniques, or
even batch files. I imagine the latter would not be terribly
difficult (to some) either.

I would think the most straight forward way would be to script an
event sink that is triggered by the screen saver. (not personally sure
exactly how to do that, but I've seen event triggered actions
before). when the screen saver fires, the event sink would trigger
the function to disable/re-enable the internet connection. A caveat
would be that this would require the/a screen saver to be used. This
would also allow the screen saver timeout to 'control' the actions of
the connection dis-/re-enabler.

If you are not running/able to run a screen saver, or want to define
conditions other than what would trigger the screen saver... I'm sure
it's possible, but currently out of my skill set.

Hi again,
I am really thankfull to all nice people who reply to my question.



I mostly prefer to write a script that "programmatically" performs exactly
the same actions that you can do manually as follows:
From the "Network Connections" window, choose a specific connection e.g.
"Local Area Connection 1", choose the menue "Disable this network device".



Another script shall do the reverse, i.e. perform the menue "Enable this
network device" on "Local Area Connection 1".



I am sure that this is possible but I don't know how to do it. It seems
likely to me that this is done easily by a command within "netsh".



Best regards
M Shafaat

Since you haven't received many scripting solutions, here is a batch file
solution. With a small amount of effort you could translate it to a more
robust VB Script although you would still need to shell out to the Console
in order to execute devcon.exe. Note that different versions of devcon.exe
are required for Intel or AMD CPUs.

Device.bat
=======
@echo off
goto Start
---------------------------------------------------
Enable or disable a device.

Prerequisite: devcon.exe
(http://download.microsoft.com/download/1/1/f/11f7dd10-272d-4cd2-896f-9ce67f3e0240/devcon.exe)
16.4.2006 FNL
---------------------------------------------------
:Start
SetLocal EnableDelayedExpansion
set Adapter=Atheros AR5B93 Wireless Network Adapter

echo.
if /i "%1"=="enable" goto go
if /i "%1"=="disable" goto go
echo Syntax: Device enable / disable
goto :eof

:go
set HWID=x
set count=0
set found=no

devcon hwids "PCI\*" > "%temp%\device.txt"
for /F "tokens=*" %%* in ('type "%temp%\device.txt"') do (
set /a count=!count! + 1
if /i "%%*"=="Name: %Adapter%" set found=yes& set count=1
if !found!==yes if !count!==3 set HWID=%%*
)
if %found%==yes (
echo HWID=!HWID!
devcon %1 "!HWID!"
) else (
echo Device "%Adapter%" not found.
)
endlocal
del "%temp%\device.txt"

Thx, cool tool...
i am sure with that its possible to realise interesting scripts :)

in the case here i am sure it should be possible to read out from WMI
the networkcards and mix the Info with registry
HKLM\System\currentControlSet\enum\PCI
and get so the Hardware ID you want to disable with the Devcon Tool :)

nice nice

You might try a script with the DEVCON command-line exe.

http://support.microsoft.com/kb/311272

It'll allow you to enable/disable hardware of a specific ID in a
script.

Hi again,
The solution from Pegasus seems interesting to test, I would try it, thank a
lot to all.
