Here are the steps I followed (Please bear in mind you need administrator privileges for installing/upgrading hardware in Vista):
1. We first need the appropriate drivers that can be downloaded clicking HERE.(MIRROR) (You will be redirected to a download page where you will have to wait for a countdown to finish, and then click on the button DOWNLOAD NOW)
2. We will get a file named TIVistaDriver.zip. After uncompress it we'll get a folder named DRIVER.
3. (Step no longer necessary) We double click on the file TNET1130 (.INF) that is described as "Setup Information" and we edit it with the NOTEPAD.
4. (Step no longer necessary) We look for the following section (that starts at line #35):
;For WinXP
[TexasInstruments.NT.5.1]
%TIACXBG.DeviceDesc% = TIACXXP, PCI\VEN_104C&DEV_9066&SUBSYS_AB8013D1 ; B & G
%TIACXBG_PCI.DeviceDesc% = TIACXXP, PCI\VEN_104C&DEV_9066&SUBSYS_AB9013D1
%TIACXBG_MINIPCI.DeviceDesc% = TIACXXP, PCI\VEN_104C&DEV_9066&SUBSYS_ABA013D1
%TIACXBG_MINIPCI.DeviceDesc% = TIACXXP, PCI\VEN_104C&DEV_9066&SUBSYS_9067104C
%TIACXBG.DeviceDesc% = TIACXXP, PCI\VEN_104C&DEV_9066&SUBSYS_AB0714EA
and we delete (only!) the &SUBSYS_XXXXXXXX final part for each line. After that we exit the NOTEPAD saving the file.
5. We access the Device Manager (My Computer->Manage->Device Manager, or running the command devmgmt.msc), where we should find our not-recognised wireless card being listed as an unknown device. 6. We right-cling on it and select Properties.
7. Under the Driver tab, we click on Update Driver.
8. We choose the Option "Browse my computer for driver software"







12. You will then find the network icon on your sistray, and right-clicking on it you will be able to explore the wireless networks around.






As a final note, and as far as I know this procedure should work fine with other cards based on Texas Instruments chipset ACX111.
