802.11 book involved finding your specific hardware in the FCC Equipment Authorization System Generic Search. My Linksys WPC54gv3, for example, has these exhibits. I entered Q87 as the Grantee Code and -WPC54GV3 as the Product Code (including the leading dash). You can get these codes by reading them on your NIC.
Using the Internal Photos .pdf, I can see that this NIC uses a Broadcom chipset. Plenty of other information is available too.
