Vista - Disconnecting (not disabling) a wifi connection

Hi all

I need to disconnect (not disable) any wifi connection at shutdown so it
will start in an disconnected state at next logon.

Is this possible with only vbs+wmi and not using any shell command like
devcon.exe?

Thanks in advance.

Good to be back at these newsgroups,

PS: On Win XP Pro.

If you don't mind messing with the registry, then you can
"disable" your wireless software from initializing upon
startup.

Here is how it goes (this is from a win98 system, but the
principal ought to be the same). For a linksys wireless
card, you will find the startup utility in "RunServices",
which calls for executing the wireless utility upon startup:

[HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices]
"WMP54Gv4"="C:\\Program Files\\Linksys Wireless-G PCI Wireless Network
Monitor\\WMP54Gv4.exe"

Using the PCMag "StartCop" utility to disable this on
startup, you get the above entry deleted, and a new
entry (with the save value) placed in a new subkey
"RunServices-", that is, an almost-the-same registry
address, except for the "-" (minus) character at the end.
After disabling, the registry looks like this:

[HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices-]
"WMP54Gv4"="C:\\Program Files\\Linksys Wireless-G PCI Wireless Network
Monitor\\WMP54Gv4.exe"

In this configuration, the system does NOT run the wireless
utility upon startup. To re-enable the wireless upon startup,
just reverse the above change. Note that you don't necessarily
have to use the "StartCop" approach, you could store your
key/value pair anywhere, for example "saveWirelessKeyValue".

Obviously your registry entries will be different, and probably
your wireless utility too (unless you happen to have exactly
the same wireless card as I do).

However, I still claim that this technique ought to work,
i.e., removing (and restoring) the wireless utility entry
in the registry.

cheers, jw

Hi mr_unreliable and thanks for your response.

It uses the same backup+delete approach.
- I usualy dump the entry to a .reg file prior to edit/delete.

You just gave me a new heading on how to try to solve this.
Since it's a win service I'll try to tweek it using the registry.

A simple stop/start to the service won't work because the service stores
the state of the iface somewhere at the time it was shuted down and
restores it at startup. So whenever I start the service the iface will
imediately connect to where it was connected before (although the iface is
in manual mode?!?).

I guess MS considers this a MBIMTNTBUT - "Manual But Interrupted Mode That
Needs To Be Un-manual'd Temporarily" mode. ;-)

This approach by MS might be due to the fact that these portable things
tend to standby or even hibernate interrupting process that need to be
restored ASAP once "awakened".

Anyway, you gave me a nice push on this.

Thank you very much,
