My has an Acer Aspire V3-551-7655 running Windows 7. The Atheros wireless network adapter will often disappears for days at a time and I am unable to make it reappear, other than it randomly reappearing for reasons as mysterious to me as the original disappearance.
When the icon has disappeared, the entire adapter is seemingly gone from the system. If I go to device managers it is not visible at all. Command prompt ipconfig/all will not detect it at all when it is in its vanished state. I have downloaded the official drivers for this adapter from the Acer website and installed them several times. When the adapter is in its vanished state the drivers will not install at all; the installer simply seems to abort part way through with no error message or explanation. When the adapter is working normally I can install the drivers, but this does nothing to prevent the adapter from vanishing again the next time I turn on the computer.
Function+F3 is the hard key that supposedly turns on the WiFi on this computer, but it only works when the adapter is visible, and does nothing at all when it is in its vanished state. I have disabled the power-saving feature that allows windows to turn off the adapter under certain circumstance. The Atheros LAN (wired) adapter always seems to work, but when the wireless adapter vanishes the Microsoft VIrtual Wifi mini port also disappears from the device manager.
If anyone has encountered a similar situation please let me know how (and if) you fixed it. Any assistance is appreciated.
