Sony Vaio- Wireless switches off unexpectedly

Ask a question


I have a Sony Vaio Core laptop with i3 processor with Windows 7 installed on it. The problem is that the Wireless LED switches off unexpectedly and suddenly without any human intervention.


  • Go to Sony support page
  • Download the update and save it in the desktop, then install the update manually.
  • After installing the update it's gonna ask you to restart the computer for the changes to take effect.
  • Your Wireless adapter should work properly now.
