Wifi weird issue

[PermaChanged]

Hey guys,

On my laptop which I have just recently formatted and reinstalled everything I have a strange wifi issue. The Wifi light is off yet works fine, then when I switch it on with the toggle switch the light comes on but the wifi stops working.

Any ideas on how I can change this?

Thanks
Jonny
