WiFi connection of my Laptop !

Hi guys, I’m using Toshiba E205 S1904. I am running some problems with my WIFI. It’s not working properly.
I also try to install the latest version of the driver (2.1.38.0), but I get an error message. I have updated the HD graphics and WiFi drivers.
But the problem is still the same.
How can i get rid of this ? Any tips?
Thanks.
