This problem has surfaced recently. After I switch on my laptop from hibernate/sleep mode, it can't connect to the Internet. It displays all the available networks (wireless) but it never succeeds in connecting to the Internet. It is able to connect to the router though.
I tried many other solutions like disabling windows to turn off the adaptor, but none of these are working.
This problem persists on both wired and wireless. Rebooting will solve the problem until next sleep/hibernate. I am not sure about BIOS, but I had updated windows and drivers recently. Mine is a Dell Latitude E6410 laptop
