CAUTION: In nearly all cases you should leave auto-negotiation enabled. If you disable auto-negotiation, make sure the link partner settings match the adapter settings. The adapter will not operate at 1000 Mbps with auto-negotiation disabled.
NOTE: The Link Config tab is only displayed for stand-alone adapters. This tab is not available for adapters in teams or VLANs.
To set speed and duplex:
From the Link Config tab, click Enabled or Disabled to modify the auto-negotiation setting.
With auto-negotiation enabled, the adapter negotiates speed and duplex with its link partner.
With auto-negotiation disabled, the adapter is forced to the specified speed and duplex setting. When disabling auto-negotiation, make sure the link partner can operate at the specified speed and duplex. If the link partner cannot operate at the adapter's forced setting, communication cannot be established between the adapter and the link partner.
If auto-negotiation is disabled, force the speed and duplex of the adapter by clicking one of the following settings:
10 Mbps HALF
10 Mbps FULL
100 Mbps HALF
100 Mbps FULL
To ensure communication, verify that the link partner supports the forced setting.
Click Apply.
Restart your computer if prompted.
The speed and duplex setting is now configured for the adapter.
