How to make WPA work on Acer Aspire One ZG5 or AOA110

It has problem when I first install Windows XP with SP2 on this tiny netbook, Acer Aspire One ZG5 or AOA110. I can connect it to AP with WEP security setting. But WPA is not working.

The wireless card driver is the official release which I download from the Acer support site.
The driver version is Atheros_7.6.0.224.

I am still want to use WPA protection. I am sure the hardware support the WPA security. Because I use Ubuntu, a Linux distribution, on this netbook with WPA more than one year.


I did following upgrade or modification on Windows XP, and finally WPA encrypt wireless connection is OK now. I don’t know which step solve the problem, but all good for this AAO ZG5.

  • Upgrade Windows XP to SP3
  • Use Windows Update to install all update from Microsoft.
  • Install new wireless card driver. Which is 10.0.0.222, released on 12/20/2012, for Qualcomm Atheros AR5007EG wireless.

Google the driver and you will find the latest one. I use DriverGenius tool to find update.
