Hey everyone,
I know these are hard to find so I thought I would post them for you all. The driver for the Cisco Aironet 802.11a/b/g CardBus Wireless LAN Client Adapter (CB21AG) for Windows 7 doesn't work with the Cisco Aironet Site Survey Utility, so we need these older drivers from Atheros to get it working. The drivers are attached to this post. Download the drivers and follow these steps:
1) Uninstall the current driver downloaded by Windows update by going into Device Manager, locating the device, right-click and Uninstall.
2) Turn off all internet connections.
3) Remove the card.
4) Plug the card back in. Automatic driver install will fail so choose to browse for the driver.
5) Select the drivers you downloaded from this post.
6) Once driver is installed, launch the Cisco Aironet Site Survey Utility and it will be working!

Unfortunately does not seem to work with Win7 64-Bit
"The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems."
I'm using card AIR-CB21AG-A-K9

Hey Peter,
I've uploaded some 64-Bit drivers that may work. Try them out and let me know if they work.
Thanks,

Hello,
I was just wondering if anyone was having the same problem as I when I install the new drivers. I noticed that in the Site Survey Utility, I can't uncheck "Display in percent" its greyed out. Does anyone have this issue?

Hi,
Its nto working for me. I am trying to install on windows 7 64-bit, but it shows all drivers are not compatible. i tried the ones you posted. My system is recognizing the CB21AG as a ethernet controller and when i try to update the driver, it says its not compatible. Please help
regards
