You can change the interface metric to make one network adapter more favorable for all TCP/IP connections. The interface metric (IPConnectionMetric) for a network connection indicates the cost of using the routes in the IP routing table. The routes are derived from the interface configuration. The cost becomes the value in the Metric column for those routes in the IP routing table. If there are multiple routes that are a close match for the route to a destination in the IP routing table, the route that has the lowest metric is used. The range of valid values is 1 through 9999.

To change the interface metric, follow these steps

Click Start, click Run, type ncpa.cpl , and then click OK.

The available connections appear in the LAN and High-Speed Internet section of the Network Connections window.

Right-click the network adapter that you want to change, click Properties

Click the General tab and under This connection uses the following items box, select Internet Protocol (TCP/IP). Then, click Properties.

In the Internet Protocol (TCP/IP) Properties dialog box, click the General tab, and then click Advanced.

On the IP Settings tab, click to clear the Automatic metric check box. Then, type a value in the Interface metric box click ok 3 times.


For win 2000 Users

In Windows 2000, change the value in the Interface metric box from the default value of 1 to a different value. The Automatic metric check box is not present.

  1. I am running a PPPOE connection to connect to the internet.
    My motherboard has only one network card.
    If I am connected to the internet, I am unable to join or host LAN games, it is choosing the PPPOE connection over LAN. I`ve checked the adapter priority and I have Local area connection right at the top, but the issue remains. (keep in mind the PPPOE connection is using the local area connection to connect to the internet) I tried changing the metric value of the local area connection to 1 which didnt help either. Any suggestions here would be greatly appreciated!

  2. Thanks, that was exactly what I was looking for.
