Maximizing Ethernet Performance
Your computer performs best when the Ethernet port to which it is connected is set to
autonegotiate. Ask your network administrator to verify this setting.
Note: If you experience connection problems on your network, make sure your network
switch is set to autonegotiate, if possible. If a switch’s port is not autonegotiating, your
computer detects the appropriate speed but defaults to half-duplex mode. If the
switch’s port at the other end of the link is configured for full-duplex mode, a large
number of late events can occur on the link. If it isn’t possible to set the switch to
autonegotiate, then set the switch’s port to half-duplex. For more information, see the
documentation that came with the Ethernet switch.
