RE: auto deactivate wlan upon lan connection(docking)

You should be able to do this by creating a hardware profile.

Alternatively, here's VBS code that will do it:

' This script pings a server specified as the DHCP variable below.  If
the ping is successful,
' the script will release DHCP leases for all wireless NICs.  Users must
be local admins.

' Pick a server on your LAN and put its IP address in the field on line
11.


' Specify the local computer.
strComputer = "."

' Define the LAN DHCP server.  Put your IP address within the quotes
substituting for the xxx's.
DHCP = "xxx.xxx.xxx.xxx"

' Connect to Windows management on the local computer.
Set objWMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

' Collect a Ping response from the DHCP server on the LAN.
Set colPings = objWMI.ExecQuery("Select * From Win32_PingStatus where
Address = '" & DHCP & "'")

' If Ping was unsuccessful, do nothing.  If successful, release wireless
IP.
For Each objStatus in colPings

    If IsNull(objStatus.StatusCode) or objStatus.StatusCode<>0 Then 
        
    Else

    ' Collect all of the NICs with IPs.
    Set NICs = objWMI.ExecQuery("SELECT * FROM
Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")
       For Each NIC in NICs

          ' Find wireless NIC(s) and release lease(es).
          If InStr(NIC.Description, "ireless") > 0 Then 
            
             NIC.ReleaseDHCPLease()

          End If  

       Next

    End If

Next

WScript.Quit

The file is also attached.  You will have to substitute a LAN IP to ping
in the script where indicated.  This script doesn't disable the wireless
NIC, but will release the IP.  You could likely tweak it a bit to do
exactly what you need, but this worked great for my needs.

Hi

Is there a way to make windows auto-disable wireless when lan is
connected?
I have tried policys and some registery checking and by using the
attached
software, without any luck..
Anyone have an idea of how to solve it?
Is there any software/freewares that might do the trick?


Cheers,
chaos
