WiFi switch not working

Hi,

Dell Inspiron 3520 has Fn + F2 key combination for enabling or disabling WIFI. I would suggest you to reinstall the wireless card driver. Please enter your service tag # on the link below, select the OS and then download the wireless card driver from Network section onto the Desktop screen.

While waiting for a reply for another suggestion to fix the wifi problem, my laptop prompted me to upgrade to 8.1. After upgrading, the wifi now works. I'm not going to question why; I'm just glad it works now. 

Thanks for helping. :)
