  • For TTU residence halls, change it to Auto Negotiate, Auto, AutoSense, or similar.
  • For any other on-campus connections, if your port is configured for 1 Gbps, change it to Auto Negotiate, Auto, AutoSense, or similar. If your port is configured for 100 Mbps, change it to 100Base-T Full Duplex, 100Mbps Full Duplex, 100M_FULL or similar.

CAUTION: If you change this setting it may affect your connection in other locations! For instance, if the computer is a laptop and you take it off campus, you may have to set this option back to its default settings.
