Windows Vista incorrectly detects the miniport edge of PassThru as a WLAN adapter when you use the PassThru Intermediate Driver from the Windows Driver KitArticle ID: 932030 - View products that this article applies to. On This PageSYMPTOMS You create a device driver that is based on the Microsoft PassThru
Network Driver Interface Specification
(NDIS) Intermediate Driver from the Windows Driver Kit (WDK). Then, you install this device driver on a computer that is running Windows Vista. When you restart the computer, Windows Vista incorrectly detects the miniport edge of the PassThru driver as a wireless local area network (WLAN) adapter. Therefore, if you access the WLAN adapter manually, you may be unable to connect to a wireless access point. CAUSEThis problem occurs because the WLAN API incorrectly returns the intermediate driver as an interface that is not in a ready state.
