I have problem with Wifi Card Intel Wireless Link 4965AGN on Windows 7 dell laptop . I try to setup policy to block this card if network cable is connect to laptop if not card should be working. I enable Network Adapters in Device Class then match Vendor ID and Device ID. Blocking works fine when cable is pluged in, but when I disconnect cable wifi is turning on for 30sek. and again turn off. And situation repeat non stop (turn on and turn off all the time ) Any ideas where to look ?
