see if it helps.

OK, I've now managed to use devcon.exe to disable/enable my WiFi adapter. Here's what I did.

1. I DL'ed the “Windows Driver Kit (WDK) 7.1.0¿ from MS, it is an ISO image several hundreds meg

2. Using UniversalExtractor (http://legroom.net/software/uniextract) I extracted the ISO to a temporary folder on my HD

3. Again using UniversalExtractor, I extracted the install file "WDK\setuptools_x64fre.msi" to a temporary dir

4. In that temporary dir you will find "WinDDK\7600.16385.win7_wdk.100208-1538\tools\devcon\amd64\devcon.exe". This devcon works fine (as far as I've tested) for me under W7x64 Pro.

Along the way UniversalExtractor will prompt you with some warnings, just click OK.

*phew* so much time wasted for such a simple thing...

Note: devcon MUST be run from an administrator cmd win.

depends on how your drivers are packaged.   I've used DPINST64.exe to install drivers from the command line.  Can't say it works perfectly with all drivers, but 90% work great.

It does not require an elevated command prompt, just a regular one, but you must be logged in with an admin account.  It's great for scripting multiple driver installations.

DPINST64.exe is a MS tool that uses INF files in the driver packages to install the drivers.

the old DevCon at http://support.microsoft.com/kb/311272/ may not be compatible with Windows 7, The new DevCon is included in the WDK in the \tools\devcon directory. There are separate versions for 32-bit applications for Windows (\tools\devcon\x86) and 64-bit applications for Windows (\tools\devcon\ia64) systems. WDK V7.1.0 is available at http://www.microsoft.com/downloads/en/details.aspx?FamilyID=36a2630f-5d56-43b5-b996-7633f2ec14ff&displaylang=en
