I just upgraded my Aspire One to Windows Vista. Everything worked perfectly until I ran Windows Update to install all important and recommended updates, including a new Atheros AR5007EG wireless network driver. The laptop gave a stop error while installing the driver update and restarted automatically. Since then I have been unable to connect to any wireless network (Vista keeps saying that there are no available networks). Also, whenever I try to reinstall any version of the Atheros driver, I get the stop error again. Please help because this is driving me crazy, and I don't want answers like "Vista sucks, install a real operating system" and similar.
