No Internet since Windows 10 upgrade

Hi

I upgraded  a Vostro 430 running Windows 7 to Windows 10

Everything seems fine except none of my Internet Browsers connect with the internet now.

The WiFi symbol shows the proper connection and Trouble-shooters show no errors.

The Proxy settings seem  unchanged.

I pinged various addresses in the cmd console and they worked.Less success with Telnet, (not too savvy with that). :/

I contacted Microsoft and Drivers were mentioned but that's where the trail went cold.

Any advice would be gratefully received.
