I have a similar problem, I guess - after installing Windows 7, adapters are found ("Network adaptor 'Microsoft' on local host" (x2, for some reason), and  "Network adaptor 'Marvell Yukon Ethernet Controller.' on local host"), but they don't work. I'm currently running on a wireless (Intel WiFi 5300), and if I recall correctly, this was the only one which worked under Vista, which is... missing now, haha. Windump only lists these 3, as well. I've uninstalled URL Snooper, Winpcap, reinstalled, run as admin, but nada.

Any help would be greatly appreciated!
