Change the order of network protocol bindings
If your computer is connected to a network, network policy settings might prevent you from completing these steps.
If your network seems to be running very slowly, consider changing the order of network protocol bindings. Windows attempts to communicate with services by using network protocols in the order specified in Network Connections. To make network communications faster, you can reorder the protocols in this list from most used to least used. Usually, TCP/IP will be the most used protocol.
You must be logged on as an administrator to perform these steps.
Open Network Connections by clicking the Start button , clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking Manage network connections.
Press the ALT key, click Advanced, and then click Advanced Settings.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the Adapters and Bindings tab, and then, under Connections, click the connection you want to modify.
Under Bindings for <connection name>, select the protocol that you want to move up or down in the list, click the up or down arrow button, and then click OK.
