I was trying to update drivers from dell on my xps M140.
Then I had the blue screen of death.
It shut down.
When I started back up Windows wouldn't connect to the internet.
The computer says the inter is there but The windows won't connect.
I was trying to update so I could connect to my printer.
try do undo the driver you tried to update, like uninstall the driver, then see if your internet works. if it does, try to reinstall the driver but first restart.
