Manually reset your Internet Protocol (TCP/IP) settings

Having internet problems? Sometimes your computer's Internet Protocol settings can configure improperly or become damaged or corrupted. If you can't connect to the internet and have tried all other resolutions to the problem, resetting your TCP/IP settings might help.

Because TCP/IP settings are a core component of Windows, you can't simply uninstall and then reinstall to reset everything. Instead, you'll have to use a Windows component called NetShell utility to reset TCP/IP.

Below you'll find instructions on how to perform a TCP/IP settings reset.

Note: The instructions below require administrator access. If you are not the administrator, please contact the administrator for assistance before continuing.
