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.
