WiFi switch not working on VAIO sve141d11L

Hello,
For some reason the WiFi on my laptop isn't working. The WiFi light is lit up but it's not connected and when I go the network and Internet settings wireless network connection switch is on off. It won't let me switch to on.

I checked airplane mode and that's not on.

I tried following the directions in this thread
https://ccm.net/forum/affich-356149-wireless-switch-not-working-sony-vaio
but since it won't let me switch to the on button I couldn't complete them.

This had never happened before and It was working fine last night.

Edit: I've solved this. I thought the settings and VAIO smart network were the same but I had to turn the WiFi on there first.

any suggestions. Thank you so much
