I really try not to be dumb but sometimes it doesn’t work. I have a Cisco AIR-CB21AG-A-K9(taken right off the Cisco box). I saw the download on your website for adding support for this card to a V90. I have a V90 running XPe SP2. I am a little confused. There are two folders in the zip file. One is ADU_system32 and one is system32. I extracted the zip file into my /windows directory on my V90 before inserting the card. I checked to make sure the files were in /windows/system32 and they were. When I inserted the card, I still was prompted to install drivers. Am I missing the purpose of the download on your site? Also, I am not sure what the ADU_system32 folder is for. Could someone please offer some assistance?
