Configure a network adapter to automatically adjust speed

  • Article

TFS 2013

When a client computer is not configured to automatically adjust the link speed of its network adapter, some functions might take a long time to finish. Such functions include creating projects, saving work items, or merging code changes. In some cases, these functions might never finish, and an error message might appear that contains the phrase "The underlying connection was closed."

The speed with which a function finishes depends, in part, on the speed of the computer network. The configuration of network switches and your computers' network adapters can affect the network throughput. For example, "autosense mode" or "auto-negotiation" might be turned on, and information might be transmitted in either full-duplex mode or half-duplex mode.

To minimize the time required for a function to finish, you should confirm that these settings are set appropriately for maximum throughput. For more information about how full-duplex mode differs from half-duplex mode, contact your network administrator.
