My sony vaio pro 13 wireless capability is turned off

[Jenymackay]

Hi,
I have problem with my sony vaio pro 13, the wifi won't connect to the internet because the wireless capability turned off by itself. When i restart my laptop, the wifi turned on then suddenly turned off. How can I turn it on?
Any idea?

Thank you

I would try reinstalling the wireless driver
Get the driver from Sony's website, uninstall the driver via Device Manager in Windows, restart, install the driver.

Ok, thanks I will try. Do you mean by uninstalling the intel(R) dual band wireless?

I can give you a better idea if you can provide a screenshot of your Device Manager.

Yes, uninstall that Intel(R) Dual Band Wireless-N 7260.
Download the driver from here https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Wireless+Networking&ProductLine=Intel%C2%AE+Wi-Fi+Products&ProductProduct=Intel%C2%AE+Dual+Band+Wireless-N+7260 ONLY IF YOU CAN'T FIND IT FROM SONY'S WEBSITE

Open Intel Collaborative Performance Control (CPPC) and check CPU aggressiveness. Chances are you might find it at 100%. Reduce CPU aggressiveness to 80% (80-20 rule). This shall improve overall experience like no connection lost when packet is lost. Found this solution here: http://www.troublefixers.org/laptops/fix-sony-vaio-pro-wifi-issues/367/
