Is Your Wireless NIC Logo’d for Vista?
If you want to know if there is a signed WHQL’d driver for your wireless NIC, this page has the list you are looking for. Remember that some of the larger vendors like Atheros, Broadcom, Realtek et al produce the wireless radios in your Netgear, D-Link, Linksys etc. wireless card so if your particular model isn’t listed, it doesn’t mean no support.
Note that some drivers are on Windows Update only. This means that unless you first connect with a hardwired connection, you will never be able to pull down the driver.
