How to Enable or Disable a Network Adapter (NIC) in Windows


information   Information
A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter, and by similar terms) is a hardware component that connects a computer to a computer network.

You need a network adapter to connect a computer to a network. A network adapter can be used over a wired or wireless network. You can disconnect your computer from a network by disabling your network adapter, and you can sometimes solve connection problems by disabling and then re-enabling the adapter.


This tutorial will show you different ways on how to enable or disable a network adapter (NIC) on your PC in Windows.

You must be signed in as an administrator to be able to do the steps in this tutorial.

Note   Note
Your computer may have more than one network adapter. Each adapter is listed next to the name of the network connection that uses it. Make sure that you select the correct adapter.
