Windows 7 - Disable WiFi when connected to a wired physical network

Solution 1:

You can use the Windows task scheduler and trigger on a profile change. Alternatively you can also trigger the disconnect (via netsh wlan disconnect) on the Windows Firewall or Hardware Driver Event (e1express for my Intel Card, see event logger for details when connecting cable). If need to disable the card you can get the command line from here: http://wlanbook.com/enable-disable-wireless-card-command-line/ (it is a little less generic)

Here is an example event trigger you can import (change usernames and my_wired_network)
