Upgrading port speed in Windows

Upgrading port speed in Windows

The default port speed for customer servers (for both public and private networks) is 10 Mbps. If you would like to upgrade either of your port speeds to 100 Mbps or 1000 Mbps, open a ticket with the request. You need to approve the minimal charge before a technician changes the port speeds on your network. For more information about opening support case, see Getting support.

After the upgrade is completed on the network side, hardcode the appropriate network interfaces on your server.

Always connect to your server on the network that you aren't working on to avoid locking yourself out of the server.

Complete the following steps to force the port speed on a Windows® server.

  1. Select Start > Control Panel > Network Connections.
  2. Click the network connection that you are trying to upgrade or downgrade.
    • For Public Port upgrades select Local Area Connection 2 or FrontEnd.
    • For Private Port upgrades select Local Area Connection or BackEnd.
  3. From the Connection Status window, verify that the network card you selected is the port that you want to upgrade.
  4. Select the support tab (note the IP address):
    • For a Public Port upgrade the IP needs to be a public IP address.
    • For a Private Port upgrade the IP needs to be a 10.x.x.x address.
  5. If the IP addresses don't match, repeat steps 1-3 for the other network connection.

LAN Status

To change the speed of your LAN, use the following steps.

  1. Select the General tab again, and then select Properties. The Connection Properties window appears.
  2. In the Connection Properties window, select Configure. The driver properties window appears.
  3. Select the Advanced tab.
  4. Select Link Speed & Duplex from the property list.
  5. Select the Value tab to the right and set the port speed you are upgrading to with full duplex:
    • For 10 MBS Select: 10 Mbps / Full
    • For 100 MBS Select: 100 Mbps / Full
    • For 1000 MBS Select: Auto
  6. Click OK.

This change causes the server to immediately start with the new speed, so you might briefly disconnect while the link renegotiates.
