Hi, I've got an Acer Aspire S3-391 running Windows 7 64 bit, and I recently updated my wireless network adapter (Atheros AR5BMD222) to the latest version 10.0.0.274 as recommended by Acer's website. After updating the driver, I can no longer connect to my home wifi. When I try to connect, I get the message that no wireless connections are available (even though all my other devices can see the wifi network) and when I diagnose the problem, it says that there might be a problem with the wireless network adapter and that windows couldn't automatically bind the ip stack protocol. I've tried uninstalling the new driver and reinstalling the old one and running a system restore to before installing the new driver, both with no luck. When I try to manually configure a wireless connection, I get "an unexpected error ocurred" message. I have automatic DNS and IP address set, and when I look at my ipconfig IP, DNS, DHCP, etc all have addresses. Any help would be greatly appreciated, thanks.
