Check Windows Control Panel, System, Hardware, Device Manager and see if the device is present or yellow flagged as faulty. If flagged, uninstall it and Refresh -- at which point it may reinstall correctly.
I'm not sure what I am looking for as the wireless device. Under Device Manager there is a Network
Adapter: Altheros AR8132 PCI-E Fast Ethernet Controller (NDIS 6.20)
There is also a large list of System Devices with titles like ACPI, ATI, PCI, etc.
Nothing is flagged.
