Bandwidth Limits

Please be aware that the maximum upload permitted from an on-campus computer to an off-campus location is 650 MB in a twenty-four hour period. For more information, read Bandwidth Management (http://www.cns.vt.edu/html/data/bandwidth.html).

If you exceed the bandwidth limit, you will receive an e-mail message from CNS informing you that the bandwidth to your Ethernet portal will be restricted. To read the fulltext of this e-mail message, refer to Consequences for Exceeding Virginia Tech's Network.

Residence Hall Connections

Connections (DHCP) in the student residence halls are provided and paid for with your room. The Ethernet ports are orange and are located on a white box attached to the wall. You can set up your connection automatically using the VTnet CD that came with your room.

Notes:
  • Caution: Verify that your firewall is turned on before plugging into the network. You may use the VTnet CD to enable your firewall.
  • Caution: For Windows XP, be sure you have installed Service Pack 2 (SP2).

For manual DHCP Ethernet connection instructions, follow the link that matches the operating system on your computer:

If you have more than one computer, there are two ways to connect:

  • Use a hub. You must pay an additional monthly fee to register your hub. For more information, refer to the CNS Private Network Policy page (http://www.cns.vt.edu/html/data/privatelans.html).
  • Request an additional connection for your room. You must pay an activation fee. To sign up, visit CNS Student Telecommunications in 120 Student Services Building.
