PCI vendor 168C is Atheros Communications Inc.
(I used this database to search in, but any search engine should get you started.)
Refining the search their device 0032 yields:
Chip Number: 0x0209
Chip Description: AR9485WB-EG Wireless Network Adapter
The zip file in their notes seems to be for a "Qualcomm Atheros WiFi Driver Installation", "ProductGUID=7D916FA5-DAE9-4A25-B089-655C70EAF607", "CompanyName=Qualcomm Atheros". Try installing that one.
