Accidently Disabling internet

[someproblems]

i am not sure if this is where my problem should go, but
My friend mentioned that if i go into Control Panel, click Network and Internet, click Network and Sharing Center, click Local Area connection, properties, then uncheck internet protocol version 6 (TCP/lPv6), i could speed up the internet, but i accidently clicked the "disable" button and i don't have internet, what do i do?

If the network card is enabled, and there is still no joy, try uninstalling the device driver from within Device Manager. Reboot the system to reinstall the driver anew.

WARNING: Take note of the driver/software that will be uninstalled. Gather the necessary drivers from either the website that hosts support for your particular machine, or the device manufacturer website: Just in case Windows cannot find the proper software.

If the make/model of the machine and network interface card is provided, I'd be glad to lend a hand.

EDIT: Click Start > type network connections > Enter.
