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.
