• WIFI device not detected after installing Windows updates.

  Original title: WiFi stops working when loading Windows (Win7).

  After that the last series of Win7 update is more my Wi - Fi works.

  My computer is the only one in the affected House. Wi - Fi is on (the radio light is on) when you start up loads of Windows, and then he went. More my factory installed Atheros wireless network card is no longer visible in the device, only the Ju Fast Ethenet controller Marvell Manager. I have re-installed the Atheros driver in the hope that the system would then find the device. No luck. Even the F8 key is operable, so using the FN + F8 key to activate the Wi - Fi is a bust.

  We know that the camera is good, but Windows doesn't see a reason any. This seems to be a matter of Win7 and not a hardware problem.

  • Please let know us if there is a FIX to this problem - I spent the last 4 days of research on this and I'm not alone.
  • I can re - install Win7 or y at - it a patch that I can use? With the help of a cable Ethernet is well when you're used to a Wi - Fi connection!
