Network adapters can normally be enable or disabled through their software. When a network connection suddenly stops functioning, disabling and re-enabling it can repair the problem. Disabling an adapter provides a convenient alternative to installing and uninstalling it.
- Open Network Connections by clicking the Start button >Control Panel > Network and Internet > Network and Sharing Center > Manage network connections.
- Right-click the network adapter, and then do one of the following:
- To disable the network adapter, select Disable.
- To enable the network adapter, select Enable.
If you disable the adapter, you have to enable it again to connect to a network.
