Lost WIFI latitude 7490

[Tubardus]

Hello,

 

WIFI was working just fine until today on my Latitude 7490 using a dw1820a card. This is what I see.

 

I cleaned up my clover file using the clover pack made by @Hervé and installed the kexts proposed by @Jake Lo. I can see the Wifi symbol but not  activate it.

 

Any idea?

 

Thanks
